My dishwasher runs through its selected cycle ok via push-button control however does to get hot. I stripped the unit down to test the heater element (part no: 50277796004) which measured 26ohms impedance around its terminals, this would imply the heater element is ok. Any ideas what a working dishwasher heater element should read. Or, am i barking up the wrong tree and the fault is with the temp sensing element. Any help would be gratefully received!!
I have the same problem. First fault was caused by poor workmanship on the assembly of the PCB. There is a relay (the largest component on the board) which was badly soldered and caused some arcing resulting in solder splattered around the plastic casing and a lost electrical connection. This relay switches the mains voltage on to the heater i.e. 240V around 8.5A for a 2kW heater. (26 ohms suggests a 2215W heater for the case mentioned). Re-soldering this connection solved the problem for about a year. Now the dishwasher is showing the same problem. I have tested the relay and it is operational, but does not seem to be turning on during a wash cycle. A new board costs around £100. Zanussi will not even provide the technical details to allow a home fix. I will post my finding if I get to the bottom of this problem. It may be to do with electrical temperature sensor. My hunch is the controlling PCB is cheaply made and will not last a reasonable lifetime. A dishwasher is in itself a very simple piece of equipment with only a few valves, a pump and a heater so should not give problems in its first five years of life subject to normal usage. I will not consider purchasing any Zanussi appliances in the future.
Value of 26 ohms is about right. how hot does it get? max water temp is about 65 degc

I have the same problems on a Zanusi DE540X...the machine runs through the cycles OK but won't heat the water.
Do you know where Ican get a service manual from....preferably as a download?
