We have a Zanussi Diswasher ZDT 6053 which on occasion does not heat the water during the cycle. This happened before and when i cleaned out the filter it worked again, however this time no luck when i cleaned the filter. Any suggestions would be appreciated?

check main pcb in the fascia for burnt track or bad solder joint on pcb heater relay.open circuit heating element?.should be around 29 ohms across the heater terminals if its OK.A heater with limescale build up inside them can also cause a no/intermittent heat issue
