water dose not heat up and program will not finish,
i have tested the heater element which is okay it has an resistance of 25.13 ohms.
any help to diagonis what the problem and the part i requirer would be much appreciated

Same problem here. however after checking out the heater and thermostat as OK, I checked the voltage on the heater, 13v idle and only 40v active. I traced the wires looking for a faulty relay, and they lead back to the white microcontroller box under the control panel. I took out all the plugs (make a note of which way round the heavy duty ones go - it wouldn't start when I connected one of them upside down), opened the box and lifted the PCB. The plug at the end with the blue and orange wires is for the heater. There is a solid state switch on the board for the heater and on the back of the PCB, the solder was missing! There was no real sign of overheating, just the solder gone. I scraped back the traces a bit and resoldered, and it's working again.

The connector is right on the edge of the board, so maybe the soldering process left the solder a bit thin for the 2100 watt heater?

Getting the screwdriver out did the trick! as you look at the front of the machine took off thr right side panel. This exposes a large lump of triangular shaped concrete held on by a screw- remove screw lump slides up and out.

This allows better access to the flow through heater ( no element in this beast just this small flow through made by Bleckmann - 230vac - 2100watt.(this is a german made bit of kit and the companies web site comes with pictures an all - but thats all theyll give you- would have to say they were rapid in their response but directed me back to zanussi and lots of pounds!)

If you lay the machine back looking in from the bottom up youll find the thermostat above this heater up on the right, it will probably be obscured by some black foam padding its quite tricky to see and to get to but it looks like a brass coloured hexagonal screw with a small white coloured tube with two terminals which should have two thin red wires attached.

Other than that theres not much else in the way of hardware that can go wrong. (i since found out that the sales of these two parts are few and far between so initially look elsewhere for your problem) I took both of these off and tested them with an electric meter.
The thermostat i connected up the terminals to the meter and placed the screw end in a cup of kettle boiled water the reading on the meter dropped quite quickly indicating that it was ok! I connected the terminals on the heater to the meter and got a reading of about 25.9 ohms which is bang on for a 2100watt unit so this was ok.
I put everything back where i found it and opened the door of the machine and unscrewed the six screws at the top edge of the door panel which allows the door handle bit and the buttons to slide out as one. What i found was this, some of the wires that connect to the PCB unit (white box on right) especially the one that contains four thin red wires (the same size of red wires that go to the thermostat) were slightly loose and i mean slightly. I pushed these home and bingo the machine lives!! Long road for a shortcut but i now know this machine inside out. P.S all spare parts can be obtained via Electrolux web site via your local spares contractor thermostat £8.00 Heater approx. £40.

Same machine same problem, ive come to the conclusion that the thermosat is goosed.
Ive posted the problem with no responce so im away to get the screwdriver out and strip down the machine. when i track down the part and fingers crossed fixed the prob ill fill you in on the details!

I also have the same problem. The 70 deg program just warms the water but occationaly works through a program OK. I would appreciate any feedback.

i have the same dishwasher and exactly the same problem. The water is only warm. i remember when you open the door after theprogram finished and steam used to come out. if you figure out what iswrong pleae let me know.
