Bosch Dishwasher Control Board Replacement in Dubai: Which Faults Point to the Board, Repair or Replace, and Cost

On a Bosch dishwasher, the control board is rarely the first thing to blame, and Bosch's own pages treat it that way. Its "not turning on" pages for the UAE, the UK, Singapore and Egypt send you through the plug, the socket, the fuse, the breaker and the door. None of the UAE, UK, Singapore or Egypt pages we read names the board. Only Bosch US names "a faulty main control board or touchpad", and only after the reset, the child lock and the door have been ruled out.

Most people who search for a control board replacement have a symptom, not a diagnosis: a dead display, a cycle that will not start, buttons that do nothing, or a code on the screen. This page sets out what Bosch says to check before the board, which codes on Bosch's US list point at the electronics, what the third-party repair guides show about repairing or replacing a board, why the part number matters, and what the work costs in Dubai.

We repair Bosch appliances. We are an independent company and not an authorised Bosch agent. If your dishwasher is inside Bosch's warranty, call Bosch first. For the wider list of faults see our Bosch dishwasher repair page.

At a glance

• What Bosch checks first: power at the plug and socket, the plug fuse (13 amp on the UK and Singapore pages), the breaker, the door, the child lock and the water inlet.
• When Bosch US names the board: for buttons that do not respond, after the reset, the child lock and the door. It calls the cause "a faulty main control board or touchpad".
• Codes that point at electronics (Bosch US list): E01, E02, E03 and E04 on the main control board or heater electronics, E05 and E06 for diverter and door sensor circuits, E19 for the detergent dispenser solenoid circuit, and E0110 for an electronics communication failure.
• Two of them skip the reset: E04 and E0110 tell you to contact support.
• Beeping with no display: Bosch US says the board "might be damaged and could need replacement", and says to try a breaker reset of about 10 minutes first.
• A new board is model-specific. The part number, not the series name, decides what fits.
• A repair in Dubai: typically AED 350 to 540 before 5% VAT for a module fault, with a 90-day warranty.

What the control board does, in Bosch's own words

Bosch does not publish a description of the board for owners. What it does publish is a list of error codes, and the list says where the board is involved.

On the Bosch US dishwasher error list, the main control board appears in these entries:

What this tells you

The board is where the dishwasher's decisions turn into switched power: the heat pump motor circuit, relays, the wash arm diverter and the door sensor all sit in the list as circuits. That is our reading of the list, and it is a modest one. We do not describe the layout of any board, because Bosch's pages do not.

It also tells you the board is not one fault. A relay fault, a diverter circuit fault and a heater electronics fault are different findings on the same module, and the repair is not the same in each case.

The part people call "the PCB"

Search results use "control board", "control module", "electronics module", "power module" and "PCB" for the same area. Bosch US uses "main control board" on its error list. A "touchpad" is also named on its troubleshooting page, which suggests the front panel's buttons can be a separate item. We found no Bosch page that says how the parts are divided on a particular model, and the split differs between models, so the rating-plate number decides.

Bosch's reset advice

Bosch US's standard instruction for most electronic codes is to reset power at the breaker for 30 seconds and call support if the code returns. Our dishwasher page describes the same reset. It is a first step and not a repair, and it cannot tell you whether the board is faulty. If the code comes back, the reset has told you something about the fault, though not what part has failed.

What Bosch checks before it blames the board

Read together, Bosch's pages put the board last. This table shows what each page covers for a dishwasher that does not turn on.

Reading the table

Four of the five pages end at the power supply, the door or the water inlet, then send you to service. The UAE and Egypt pages say to contact an electrician if necessary, and the UAE page gives BSH 048030400 and a link to Bosch's repair contact page. The UK page's only caution is the fuse rating and the electrician. The Singapore page adds the warning against DIY repair.

The US page is the only one that names the board, and it does so for one symptom, buttons that do not respond, and as the last item in the list. Its words are: "a faulty main control board or touchpad". It gives no probability and no test.

Why this order matters

The cost of a wrong guess is high. Our dishwasher page says a drain pump costs far less than a control module, and a dead display can be a plug fuse. The first five checks cost nothing. In our visits the plug, the breaker and the latch are checked first for that reason. That is our practice and not a Bosch figure.

A word on the latch

For the door itself, see our Bosch dishwasher door, hinge and latch guide.

Bosch US says a faulty door latch "may inhibit operation even if the door seems closed", and that a broken latch needs a professional "for safety reasons". The Bosch UAE page says to close a caught door lock firmly. A latch failure can look like a board failure from the front, so we check it before ordering a module. That is our practice.

Codes that point at the electronics

Bosch US's list is the one place Bosch puts the electronics into codes. Here are the entries that involve the board or the dishwasher's electronic circuits, with what Bosch says to do.

Three points from the table

First, a reset is Bosch's advice for most of these, and E04, E0105 and E0110 are the exceptions. For those three Bosch sends you to support at once, so a reset gains nothing.

Second, E27 is not a dishwasher fault on its face. It says the household supply to the unit is too low, and Bosch's step involves an electrician. A dishwasher with E27 does not need a board until the supply has been checked.

Third, E19 on the US list reads as a dispenser solenoid circuit fault, while Bosch's South Africa, Singapore and Switzerland pages describe E19 as a problem with the dispenser or an internal valve. Our E19 guide covers the washing machine meaning and notes the dishwasher difference. We do not claim these are the same description.

What the table does not say

Bosch's list does not say that a code means a board must be replaced. It says which circuit reported. A circuit fault can sit in the board or in the part the circuit feeds, such as the heater, the diverter or the door switch. This is why a technician tests the part before ordering a module.

Related codes we cover separately

• E09, a heat pump heater fault, has its own guide.
• E15, water in the base, has its own guide, and it matters here because of the next point.
• E24 and E25 are drain codes: see the E24 guide and the E25 guide.

Symptoms owners report, and what they usually turn out to be

A code is the easy case. Many board faults show as behaviour, so here is a plain reading of the common ones. The Bosch US page is cited where it says something. The rest is our experience.

The child lock

Bosch US says the child lock can make "the door and controls unresponsive". It says to find the child lock button and hold it down, which "will usually resolve this issue". The button differs by model and the booklet shows it. Our dishwasher page covers the button lock for cancelling a cycle.

What we cannot say

We cannot give you a percentage for how many dead dishwashers are a board. No Bosch page does, and we do not quote a figure from repair sites. What the sources support is the order: power, door, child lock, reset, and then the board.

Safe checks, in order

These steps come from Bosch's pages and are the ones an owner can do without opening anything. They are the same whether you message us on WhatsApp or not.

1. Look at the display and write down any code. If there is a code, use the table above.
2. Check the door. Close it firmly. Bosch UAE says an open door prevents the dishwasher from starting, and that if the door lock seems caught you should close the door firmly.
3. Check the child lock. Bosch US says to hold the child lock button.
4. Check the plug and the socket. Bosch UAE, UK, Singapore and Egypt all say to test the socket with another appliance such as a lamp. The UAE and Egypt pages also say to try the neighbouring socket if it is a double socket.
5. Check the breaker. Bosch UAE and Egypt say to look at the residual-current breaker or the fuse.
6. Power cycle. Bosch US says to unplug the unit for at least 5 seconds. For most electronic codes Bosch US says to reset power at the breaker for 30 seconds.
7. For beeping with no display, Bosch US says to try a breaker reset of about 10 minutes first.
8. Check the water inlet. Bosch UAE says a water supply problem can also stop the machine starting.
9. Stop and book if the problem remains.

The plug fuse

The UK and Singapore pages say to swap in a fuse you know to be good, and to make sure it is a 13 amp fuse. That is a plug-top step for those countries' plugs. The UAE and Egypt pages do not mention a plug fuse, and plug types differ. If your plug is fused, a fuse of the rating on the plug and on the booklet is the one to use. Do not fit a higher rating to stop it blowing.

What a reset cannot do

A reset clears a temporary fault. It cannot repair a failed component. If the display comes back after a reset and the fault returns later, that is information for the technician, so note when it comes back and what the machine was doing.

What to leave alone

Bosch's pages do not tell owners to open anything, and the Singapore page says to book an engineer. The third-party guide discussed below starts by removing the control panel, and its first warning is to disconnect the dishwasher from power.

• The panels. The module sits behind them.
• The wiring. The module's connectors carry mains voltage. A shorted wire can damage a board, as the Q&A on one parts retailer's page for a Bosch board notes.
• Any soldering. Repair guides for boards exist and are discussed below. They are not instructions for a machine you own.
• A used or look-alike board. The part number decides fit.
• A bypass of the door switch. Bosch US says an improperly closed door prevents the machine starting "due to safety mechanisms".

If the machine smells of burning, trips the house electrics or shows water near the panel, switch off at the wall, close the water tap and book.

Water and the board

A dishwasher that has leaked is a different case from one that has simply stopped. Our dishwasher page says water that reaches the control module turns a cheap repair into an expensive one.

How water gets there

Our leak table lists the door seal, the hoses and the pump housing as the usual sources of a leak, and our door seal guide covers the first. Bosch US's E15 entry is water in the base with leakage protection activated, and it says to turn off the water inflow, then contact support. Our E15 guide covers it.

What this changes

If water has been near the front of the machine, tell the technician. We check the seal, the hoses and the pump housing along with the module, because a new module on a machine that is still leaking will fail again. The cost of the seal or the hose is quoted separately.

A forum case worth knowing

On the AppliancePartsPros forum, an owner of a Bosch SHE3AR72UC reports E09 at the end of every cycle starting right after a control board was replaced, and the case in the thread is unresolved. We cite it as a forum post. It is a single case and not a statistic, and it shows that a new board does not clear a symptom whose cause lies elsewhere.

Repair or replace the board: what third-party sources show

Bosch's pages say nothing about repairing a board. Two third-party sources show what the market looks like, and we label them as such.

A component-level repair guide

iFixit's community has a guide for a Bosch SRI45T45EU/18 control module, a specific module with a stated symptom of total failure, no display, no sound and no button response. The guide repairs the board by replacing several components, including a voltage converter chip, a protective resistor, a capacitor and a varistor. It uses a soldering iron and a multimeter and warns to disconnect the dishwasher from power before the rest of the steps. It also says the replacement resistor "must be fire-proof / flameproof".

Three limits matter here:

• It is one module on one model. The guide does not claim the same fix works elsewhere.
• Its commenters disagree: one needed only two parts, and another said two others looked fine.
• It says nothing about compatibility or programming after a repair.

A parts retailer's listing

PartSelect, a US parts retailer, lists a Bosch main control board, manufacturer number 00266746, as replacing six earlier numbers. Its page carries a note that the module has been updated with new smaller LEDs, its model cross-reference section is empty, and its Q&A shows a suggested alternative board that is discontinued. A customer there notes that shorting a wire may damage the control board.

What we take from the two

• A board can be repaired at component level, by someone with the skill and the equipment, on a failure that is a few components. We will not tell you every failed board is repairable.
• A replacement module is a matched part. The numbers get superseded, the revisions differ, and a fitment list may be absent.
• Neither source is Bosch. Bosch does not say how it treats a failed board.

What we do

Our service page lists the work as "repair or replace the module". The technician says on the quote which it is. If a replacement is needed, we ask for the E-Nr and order against it, and the part number appears on your invoice. We do not claim that a part is original Bosch on the strength of a number. If a component-level repair is possible on your model, the quote says so, and you can choose.

Which panel do you mean?

Searches for "front panel replacement" and "panel replacement" on a Bosch dishwasher can mean three different things, and the price and the part differ.

What to do about each

If the buttons are dead, do the child lock and reset steps first. If they stay dead, a technician decides whether the fault is the panel, the module or the connection between them. For a damaged outer door front, send a photo and the E-Nr and we quote it as a separate job from the electronics. We found no Bosch page that prices or describes door-front replacement, so we do not describe how it is fitted.

Home Connect and the "power module" question

Some searches say "power module" for the electronics, and some owners wonder whether a Wi-Fi fault means a failed board. Our dishwasher page covers Home Connect: it is a Wi-Fi module and app on selected models, and connection problems are usually the router or the app. We check the module only if the machine also misbehaves. A dishwasher that runs normally but has lost the app is not a board fault on that evidence.

If the failure followed a power event

Some boards fail after a trip or a cut. Bosch's pages do not tie board faults to power events, so we do not claim a cause. What Bosch US does list is E27, household power too low, with a breaker reset and an electrician for the incoming voltage if it recurs.

What helps the technician is a short note:

1. When it happened, and whether the lights flickered.
2. Whether other appliances were affected, or the breaker tripped.
3. Whether the machine was running at the time.
4. Whether anything else on the circuit changed: a new appliance, an extension lead.

If other appliances were affected, have your building's electrician look at the supply as well. A new module on a supply with a fault is a poor investment. This advice is ours.

Reading a quote for a module

A control module is among the larger single items on a dishwasher quote, so read it as you would any significant bill. This applies to ours as much as to anyone's.

1. Is the part named? "Control module" or "panel" is a start. "Electronics" is not enough.
2. Is it tied to your E-Nr? The quote should say which model code the part was ordered against.
3. Was the simple cause ruled out? The latch, the supply, the child lock and the code.
4. Was a leak checked? If water reached the module, the quote should mention the seal, the hoses or the pump housing.
5. Is repair offered as well as replacement, where it is possible? If the answer is "replacement only", ask why.
6. How long is the wait for the part, and is the price the same?
7. What is the warranty, and what does it cover? Ours is 90 days on the part and labour for the repaired fault.
8. What do you pay if you decline? It should be a number, not a range.
9. Is VAT shown as a line? Ours is 5% and is added to the quote.

If a quote cannot answer the first three, ask for a second opinion before you approve.

Freestanding and integrated machines

The fault is the same on any model, but the visit is not. This comes from our own work and not from a Bosch page.

• Freestanding: the front panel and the module are easier to reach, and the machine slides out for testing.
• Fully integrated, behind a cabinet door: the machine often has to be pulled out of its cabinet, which takes longer and is the reason our quotes sit higher for it.
• Semi-integrated: the control panel is on show and the rest sits behind the cabinet front.

Tell us at booking which type you have. The control panel on an integrated machine may be on the top edge of the door, and a photo helps.

Matching the part

A replacement board has to match the machine. These are the points to check.

The E-Nr

The E-Nr is on the rating plate, a sticker usually on the edge of the door or on the inner side of the tub, depending on the model. Bosch Singapore says to note the E-Nr and the FD number to book a repair. Our dishwasher guide explains where to find it. Send us a photo of it, as it saves a visit.

Why the series number is not enough

Our dishwasher page explains that two Serie 4 machines with different model numbers can use different pumps, heaters and control modules. The same is true of boards, so a part bought by series name is a guess. Our Serie 6 and Serie 4 guides cover the line-up.

Superseded numbers

PartSelect's listing shows one number replacing six. That is normal for a part that has been revised. It also means the number on an old board may not be the number to order. We trace it from the E-Nr, not from the old board.

Module or panel

Some machines have a separate front panel with the buttons, and Bosch US names a "touchpad" next to the board. Ask the technician whether the fault is in the board, in the panel or in the connection between them. The quote should name which.

Configuration

We found no Bosch statement about whether a new module needs configuring to the model. We will not claim either way. The technician tests the machine after the fit.

The visit and the cost

The AED 99 inspection includes the visit, the diagnosis and a written quote. If you approve the repair, the AED 99 comes off the price. If you decline, it is all you pay.

What the visit covers

• The symptom, run on the machine.
• The simple causes first: the supply, the door latch and switch, the child lock and the code.
• The connections, where the module meets the panel and the wiring.
• The module, tested last when the others pass, as in Bosch's order.
• The water history, so we check for a leak that harmed it.

Typical costs, excluding 5% VAT

What moves the quote

Three things. The part matters most: a module costs far more than a latch. Access matters, since an integrated dishwasher behind a cabinet panel takes longer to pull out and refit. And stock: our dishwasher page says model-specific parts such as control modules and heaters are ordered once the fault is confirmed, so the price is the same if the part is not on the van but you wait for a second visit. We tell you the lead time before you approve.

A worked example

A technician confirms a failed module on a freestanding machine. The all-in price is AED 460, with the AED 99 inspection included. VAT adds AED 23, so you pay AED 483. If you decline the quote, you pay AED 99 plus AED 4.95 VAT, a total of AED 103.95.

The warranty

Every repair carries a 90-day warranty on the parts fitted and the labour for the repaired fault. If the same fault returns inside 90 days, we come back at no charge. The part number is listed on your invoice.

Repair or replace the dishwasher

Compare the written quote with a current price for an equivalent new machine. A workable rule, and it is ours and not Bosch's: if the repair costs less than about half of a new equivalent and the machine is under about ten years old, repair it.

Our dishwasher page works an example with assumed prices: an eight-year-old Serie 4 with a control module fault and a quote of AED 520, against a new machine at about AED 2,200, puts the repair at 24%. If the tub, racks and seals are sound, repair it. If the door seal is split and the racks are rusting, this is the first of several bills, so consider replacing. Check current prices before you decide.

Three questions help. How old is the machine? What else is wearing: the seal, the racks, the pump? And is the board the cause or a symptom of a leak? A quote for a module on a machine that is still leaking is not good value until the leak is fixed.

What to tell us

• The E-Nr from the rating plate, as a photo.
• The display, as a photo, with any code.
• What happened first: the machine stopped mid-cycle, a cycle would not start, or it was dead after a power cut.
• What you have tried: the child lock, the door, the plug, the breaker, the reset.
• Any water: a leak, a split seal or water in the base.
• Anything electrical: a trip, a smell, a hot patch.
• Access: whether the dishwasher is integrated behind a cabinet panel, and your building's access rules.
