Diplomat ADP 8224 Dishwasher E3 error

Re: Diplomat ADP 8224 Dishwasher E3 error

Did you get the problem fixed?

I have the same…..Tested the Heating element 25.6kohms so OK
Tested the thermostat in hot water it switches

But the heater element doesn’t get hot

any other clues? I have of yet not looked for the thermostat in the door, but guess where I’m off to now?

The cycle completes in 45 mins and the water temp changed from 18.3 to 20.5 Deg C, but thats probably because of the circulation pump and not the heater element. or just natural convection from the surrounding air.

Contary to popular belief there is no door Thermostat unless its that invisable kind that cowboy service engineers change and charge you a
fortune!!!!!

This post has been read by almost 2500 people and still no one can come up with an answer…………..hum!, maybe no one knows the answer or is willing to tell more likely!!

Correct it’s a thermistor but definitely not invisible 😉

Oh for a wiring diagram…………… 😥 😥

The door thermistor seems only to report the maximum temperature reached during the cycle therefore has no influence on the Heater operation.

(The heater element works fine – Having put 240V across it, it heats up)

Is there a flow switch in the circuit? Or any other kind of condition/operation that needs fulfilling before the heater operates?

Apart from the obvious, like door lock, power on, overtemp not tripped.

Re: Diplomat ADP 8224 Dishwasher E3 error

The thermistor in the door is the temperature control. It gives variable values depending on temperature, these are matched against a comparator array of resistors on the PCB to interpret temperature.

If you have continuity everywhere there is little left but the pcb itself.

Found and solved the problem

The main heater relay on the PCB – It cost a whole £2.45

The original part “Finder 45.61” replacement “Finder 45.71” the replacement has a higher temperature rating than the original hence the number change.

If your handy with a soldering iron this could save you the £70 call out + £130 for a new PCB, or even the £50 some are being charged to repair said item.

Good Man Rest!

Same problem on mine! Have a replacement part on order.

Thanks very much for the help on this one.

The E3 problem has just started happening on my dishwasher.

I’m quite handy with a soldering iron so I should be able to handle replacing the relay… But could you give me a hint as to where the PCB is located and how to access it? Is it in the door or within the body of the machine? Any hint as to what panels to remove, appreciated greatly.

cheers,
Tony

Hi Tony

From memory (a sleep deprived one at that!) I seem to recall everything being in the door panel. If you remove the front panel you can then remove the screws which hold the internal cover on and take this out. I remember that the cables could all be removed as they all had plugs on. The PCB could then be taken out, the relay replaced and all put back together. In total it only took me about 20 minutes to sort it.

Good luck!

Ian

Hi

Can someone tell me where the resettable thermostat is please. My machine doesn’t seem to have any water injecting into it, did a reset and there’s water now but won’t heat up, hoping it just needs the thermostat reset.

Appreciated.

Re: Diplomat ADP 8224 Dishwasher E3 error

Look at the heater. There is a dome poking through the floor of the machine under it. This is the safety thermostat. Obviously, you need to get under the machine to see if it has a red button to press (some don’t). Remove plug, door outer and lower front panel to access.

Re: Diplomat ADP 8224 Dishwasher E3 error

Pressed it with no improvement, the red button doesn’t seem to have any resistance when pressing the button, very loose. Can I bridge the thermostat to test if that’s the problem?

Appreciated.

Re: Diplomat ADP 8224 Dishwasher E3 error

If it doesn’t “click”, it hasn’t tripped.

You need a test meter to solve this. Basic resistance checks trough the heater, safety and wiring back to the pcb will eleminate the components.
