Re: SIMPLE PCB REPAIR TIPS
MIELE EL200 D PCB
There are post in the forums about this, but thought it would be helpful here.
Fault after switching on a program, rinse light flashes indicating no spin/motor fault.
Find the small round reddish brown fuse, if o/c chances are orange relay contacts are
welded together. Change both and should be good to go. Cost of repair to board approx £8-10.
Parts from http://www.farnell.co.uk Relay Part No.1629053. Fuse Part No. 1596442Re: SIMPLE PCB REPAIR TIPS
One from a member of the public. 😀
Hotpoint TDC dryness module, no heat fault.
1x RT314024 and 2x RT114024 required.

Re: SIMPLE PCB REPAIR TIPS
Gram Fridge K400RU and similar freezer
danfos board 077F2310BJ and 077F2311RU
was asked to take a look at this unit and a freezer of the same make
both these units use a small Danfoss control board mounted at the top
fault was no compressor run
fault was traced to the relay on the board which is a bi-stable relay, therefore the voltage is only applied momentarily, so it is difficult to measure the voltage at the relay to determine if its failed
during the time I played with this board I found a test procedure that was aimed probably at production testing. both the boards in these units have 3 push buttons but only 1 is obviously accessible but the other 2 are there but you have to feel for them.
procedure
turn off unit at wall
press and hold centre and right hand button
turn on unit at wall
after a few seconds release buttonsif you now press the left hand button the relay will open and close press once “open” press again “close” and so on
it will revert to normal operation after about 30 secs or if you turn off and on again
at £100 a board or there abouts and in short supply this is a much cheaper option
hope this helps someone

Re: SIMPLE PCB REPAIR TIPS
whirlpool azc6470 (produced in 2012) condensor dryer. fault f04 which means earthing fault, open thermostat or faulty pcb. if no earth fault or open thermostat change all three “hf115f relays on the board should solve the trick. must reset pcb afterwards to get the dryer operational
Re: SIMPLE PCB REPAIR TIPS
Another variation on the Indesit/Hotpoint dishwasher pcb with no heat fault.
Re: SIMPLE PCB REPAIR TIPS
Hotpoint/ Indesit dishwashers completely dead after power surge or power cut, later models/ heat pump style eg FDF780X but loads of others. ( the ones with the power pcb under the door).
Flat above a local pub, company came out to test the fire alrams and turned the power off and back on again, Dishwasher (although not on at the time) never worked again… nor did the Hotpoint Fridge Freezer.
Popped the board out to see hole in top of capacitor:the 10 ohm resistor alongside was open circuit and burned underneath- could not see that until I changed the cap. cap is 10uf 400v (RS 365 4751) once both replaced machine up and running.
now on to the fridge!Re: SIMPLE PCB REPAIR TIPS
Hotpoint Fridge Freezer model FF4DXUK but loads of others, the type with a power pcb at the rear.
Appliance dead (no light even) after a power cut (see above post)
PCB had blown 10uf capacitor and 10 ohm resistor (3 watt wire wound in this case) open circuit. Replaced both and all now working fine.Re: SIMPLE PCB REPAIR TIPS
I have a diplomat adp8234 PCB not heating. no power to the coil on the relay. any advice.

This thread is purely for people to add repair tips etc. You should post a new question in the Trade Technical Thread. 😉
Re: SIMPLE PCB REPAIR TIPS
On all of these errors/faults, check the capacitor C17 for domeing, remove & replace as necessary with 10v 680mf.
