Beko DW686 – soft ticking noise below control panel issue

[bluin]

I have an integrated Beko DW686 (full size). It’s in excellent condition but has just started to make a soft ticking noise when switched on – just below control panel. This lasts for a few seconds and the control panel does not display until the ticking stops. I can then run the dishwasher fine when ticking stops – but I’m guessing this will become a bigger issue over time.

*Additional: If i leave the dishwasher on, when i press start program it sometimes makes the same ticking noise and will lock me out of the control panel (i can still see display – and again no error codes). It’s still illuminated with the program preset but the program/cycle won’t start until the ticking subsides. If I leave it on the program and shut the door the cycle will eventually start, when ticking stops.

I have not received any error codes and nothing is blocked (my wife swills the items before it goes in the dishwasher – so even the filter doesn’t get dirty)

Things I have tried/looked at:

• Unplugging for an hour to reset
• Checking for debris in base of dishwasher and water
• Checked nozzles etc…
• Tried doing a reset using the buttons – but doesn’t seem to apply to my dishwasher

Any advice would be greatly appreciated, as I’m quite happy to replace any advised parts myself (my layman instincts thinks that it’s a noisy relay and i need to replace control panel/PCB – but I know nothing about dishwashers)

sounds like the main board is failing

they seem to be quite cheap often under £40 for the part

Thanks for taking the time to reply, Dave.

I realise this is diagnosis over the ether, so no guarantees etc – but would this be the part I should experiment with replacing:

Additional: I will need to remove the wooden fascia panel off the front of the appliance when I attempt to fix this, but i can’t find any instructions/info on my machine on how to do this. Some integrated Bekos have screws others have a combination of clips and screws. Is there a chance you know how the fascias are attached on this particular model? (knowing my luck, I’ll fix the problem but ruin the aesthetics in the process…)

module look correct and yes its likely its the fault. may just be an ageing capacitor but that gets into electronics

check with site before you buy as to look up part no you need the serial no on Beko

as for the outer door it all depends if the kitchen fitters are good or not

go round all the screws on the inside of the door. remove each one. if its less than an inch put it back. there should be 4 long screws if its done correctly

after that the outer door should slide down and come off

Thanks, good advice – and it’s reassuring that you think it may be the issue, too (i realise there are no guarantees – but appreciate an informed/experienced opinion).

I will update the thread when I get around to changing the part. Which could be very soon if it stops working altogether…

Excellent – thanks for the detailed tutorial, Dave I really appreciate your experience and time given.

It finally died over the weekend so I’m ordering the PCB today.

I’ve been scrolling through dishwasher PCB replacement on YouTube and so far they only show ‘freestanding units’ as examples (front display). My dishwasher is ‘integrated’ and so the panel is on the top. Do you have any advice for removing the independent front facing panel at the top of machine? (I’m presuming this is the only panel I need to remove and the PCB is behind it).

i.e. should i expect resistance, will there be clips or velcro etc? Should i expect anything to be attached to it?

Any advice would be appreciated.

take the bottom of the door off first

then you can remove the control panel

if you dont take lower door off then the wires would be too tight to work on it

Brilliant – thank you!

So, remove the lower section of the front skin first (to give me room) and then remove the the upper thin panel (if needed)?

*when you mention ‘control panel’ – is that the PCB? (they’re separate on my machine)

[electrofix]

as long as you can access all the wires and the panel to disconnect then do it anyway you can

dave

[bluin]

Thanks, Dave

From where the ticking sound is coming from I think you’re correct – in order to replace the PCB I will need to remove the lower skin. But, i will heed your advice and remove the above panel to access wires to the existing control panel which the ‘new PCB’ will need to plug into.

Thanks again for all your help. Hopefully, it will be prove to be the fix. If not it was worth a ~£40 educated guess/punt as the machine is in excellent order…

panel comes off a treat

carefully take all the screws ouT and ease it off

the only thing to beware of is some of the metal edges can be very sharp

Dave

[bluin]

Thanks for all your great advice, Dave!

No matter what the outcome you’ve made this experience a lot easier and safer. The sharp edges i would have completely overlooked while concentrating on everything else. You will have definitely saved me some blood loss.

I will update the thread for continuity and for the benefit of other searches – but your help has been invaluable, throughout – greatly appreciated.

Taken lower skin/panel off, looked up into the above panel and looked behind insulation etc and i cannot see anything that looks like the PCB that i ordered (i checked with BEKO that it was the right part)

Part:https://shop.ukwhitegoods.co.uk/1755…control-module

Should i take the new PCB out of protective plastic box? Very confused – expected to see replica of the PCB box in an obvious place behind panels/insulation.

My limited knowledge has come into play – am I missing something obvious – or looking in wrong place?

I’m even wondering if this is the part I should have ordered – it’s called a ‘display’ PCB?

https://www.bekospares.co.uk/display-pcb/product.pl?pid=3997652&query=dw686

but i thought that was just the display.

With insulation/compactness – it’s much trickier than i expected…

[bluin]

I’m resolving the issue by buying a new one.

PLUS, the kitchen fitters completely screwed me 7 years ago by rooting pipes and cables before fitting the kitchen and it’s been a bigger nightmare removing it. Even the kitchen floor is a different height to that which the appliance sits on (they didn’t floor all the way back) – which made things very tricky again.

Will fit myself this time.

been there kitchen fitters are a pain

been to a dishwasher today for a client. had a new kitchen fitted and they did not connect the water pipe

as for the module its the correct part no

the display module is as you thought just display
