Hi, I have a Electrolux ESF 6230 which I believe isn't heating any more.All programmes takes long time to finish and the washing result is poor. When the programme is finished and I open the door, the steam is not as hot as used to be./Lukas
I have unscrewed the cover on the front and inspected the PCBs. Didn't find anything burned there.
Ok for a no heat fault this isn usually either down to a faulty heater element or the control board in the door.
As you have already inspected the board and cannot see any burn marks or dry joints then you need to check the heater.
Pull the dishwasher out and remove the right hand side panel. From there at the back you will see the heater. Its the silver cylinder.
With a mutimeter you need to test the heater. It should read about 28 ohms. If faulty then it will need to be replaced.
But if the heater is fine just check the wiring going from the heater to the board. As sometimes the wires in the door can break. Quite rare on these dishwashers but can happens.
If thats ok aswell as the heater then it will be the control board. As the heater relay on the board will have burnt out inside it.
I opened the right side panel and found the heater. It measures 25 ohms. Then I plugged in the mains and turned the dishwasher on. After a little while I can measure 230 Volts across the heater. Hopefully it works now. I will let the program run for a while and see if gets hot.
No worries let me know how it goes.
No, unfortunately it only heated for a short while.
Since the heater measured ok, and all wiring is in mint condition, I've focused on the control board. I opened the control box, reconnected all the wires and started a programme. The relay is getting somewhat hot. The relay also starts switching on and off when I move the control board around. I guess it must be the relay that is faulty, right?
Thats correct the relay is the problem.
Now we just replace the control boards on these but if you are handy with a soldering iron then you can just replace the relay itself and this should cure the problem for you.

Ok, I will get a new relay and replace it.
Thank you for all advice!
