My Zanussi ZSF6160 dishwasher (2 years old)stopped heating during both the wash and drying cycles. A repair man imediately suspected the control relay rather than the heating element. He subsequently dismantled the control module and found a black burn mark on the back of the control module PCB.
This call out cost me £30 and he then quoted me a further £216 to fit a new control module!!!!!
Once I had regained my composure I armed myself with soldering iron and multimeter, took the heating element control relay off and found it to be working perfectly, thus it was the PCB trace that had failed with carrying the 10A current thus with some extra beefy wires soldered to back of PCB to avoid any further PCB burn out I have cured my dishwashers ills and it now works perfectly again! The way the repair man knew exactly what the problem was I suspect that this is a common problem (design flaw) so I want to let others know that all that is required is a bit of resoldering rather than a hefty repair bill or a new dishwasher
Is this weak PCB trace, carrying 10A, built in obsolescence?

Re: Water not heating
Probably not, believe it or not. If they actually designed a trace to fail under load, then they could not predict when it may happen. Yes, things get more load-some over long use and demand more current, but the pcb trace was probably not intentionally too small. Let's say it was designed too small. So at first startup it carries 9.5 Amps. The next factory unit draws 9.8 amps. the next unit, wait a minute, draws 10 amps and blew the trace before it got shipped. I think this under-design was a simple oversight, but one that should have demanded a product recall from Zanussi that would send a tech to every unit to install a pcb with a beefier trace. Email Zanussi and complain! Just curious...can you measure how wide is this pcb trace? It should be about 1/4 inch wide.

the dishwasher might accept cold water but must heat the water up during the cycle. If it does not then check the heater circuit......element...thermos NTC, with a meter for electrical continuity....some dishwashers stop mid cycle if the re is no heat but some go right through on cold depending on the make.. good luck
not familar with the code but usually wash has a built in thermo stop to wait for water to heat to correct temp,if it works normally in a rince cycle and spins out and finishes properly i would look at heat element or stat,hope this helps

Hi Guys My dishwasher this morning has desided to not work correctly. Its a ASKO 1302 about 20 years old. It has been a very good machine.
Over the last couple of weeks during the washing cycle, the dishwasher has been making a loader noise than usual.
1. Today, the dishwasher timer, travels all the way through its cycle, but very little washing take place. 2. Soap power is still there, plates not clean!!!! 3. Water is hot 4. At the end of the cycle, there is no water in the dishwasher.
5. I'm thinking the problem could be the pump needs replacing. What do you think? Greg
Just bought a Bosch dishwasher and we were told that they have no heating mechanism to dry the dishes, which is why they are more energy efficient. You are supposed to leave the door closed for at least one hour after the cycle is complete. The heat that has built up inside during the wash cycle will dry the dishes. It is also recommended to always use JetDry. If you follow this advice, the dishes will come out fine.
Check disposer plug. If a garbage disposer has been recently installed, it is possible the disposer drain plug was not removed. The drain plug is a plastic piece in the disposer that blocks the hole where the dishwasher hose connects. Also check the hose connected to the disposal. Mine apparently had a kink in it. When I straightened the hose the dishwasher drained at full speed (I recently had a plumber re-route a hot waterline. He must has bent the hose). Hope this helps. If not go to the GE website. That's where I found my answer.
