Question about Dishwashers
Our machine is not heating the water. I have confirmed that the heater unit has a internal resistance of 26ohms and is getting 240v on the active side. However it is only getting 85v across it's active and neutral that goes back to the control board. I am guessing that the control board needs replacing as the resistance from G5 to G6 is only 2Kohms instead of the 6Kohms as mentioned in your previous post.
I was hoping to get a copy of the wiring diagram to confirm, before having to purchase a new control board.
It sounds like the control board is faulty. have you checked for dry solder joints on the control board? also it is important the check the resistance of the taco on the wash motor. last of all don't worry to much about the 2k ohms of the temp sensor as it can vary lots depending on the temperature.
if you give me ur email i can send you the service manual and wiring diagram.

mine had this exact same problem - it turns out that the relay on the control board had not been soldered on properly. mine has shorted out over time, and caused a lot of charing of the localised area. i checked the relay, it was okay, so have resoldered the board and all is working for now.
i called Electrolux - 1800 001 218 - to report the problem, as i believe there are too many peoplew reporting this issue for it to be a one off. i was also concerned about a fire risk, as the charing on mine was considerable.
too be blunt, Electrolux didn't seem to care too much, unless if i wanted to pay to have someone come look at it, despite the fact that i am an electrician.
Electrolux currently say that this is the first time this problem has been reported - despite that fact they are aware of this thread. i would encourage anyone whoi has this fault to call the above number and report your problems to them, as i believe a recall may be waranted, and, should your unit have serious problems (fire) it is on record.
Electrolux currently have a recall on a couple of other dishwashers due to the fact they pose potential fire risks - see www.recalls.gov.au

I have had a similar problem and yes, the problem is the load side connection between the power relay and the circuit board. I have resoldered it and laid over that part of the board circuit, heavier wire to reduce local heating. Unfortunately, the problem arises again from time to time.
It's just a very poor piece of electrical design !
I believe the only permanent solution is to insert a secondary relay between the circuit board and the heater feeder wire in order to reduce the current (and hence potential to overheat that section of the circuit board. I am considering fitting a relay with a 240 volt ac coil but to simplify wiring but need to get a wiring diagram in order to arrange the neutral side connection for the pull in coil.
A circuit diagram would be VERY helpful.
