Ok thanks Dave

Thanks Dave, I’ll keep digging! I really appreciate your time and help 🙂

Hi Dave,

Thank you for that.

I really am at a loss now; I had the PCB repaired, but the same cut-out 5-10 mins into the warm cycle as per video occurs. I was informed that the PCB was faulty and fully repaired, but I need to seek clarification as to what was fixed.

The only other thing I can think of would be the power on/off button via the user interface circuit board. When pressed on/off in quick succession, this creates the same clicking/relay noise. Perhaps heat from the machine and steam due to fatigued seals is creating a short somewhere on the board? I’m really not sure, but just a thought.

It’s just very confusing as it only occurs during the first 10 mins of the heat cycle.

Temperature sensor @ 20 degrees Celsius = 18500 ohms

Hi Dave,

Do you know what the ohm reading of a turbidity + temperature sensor should be at room temperature?

Zanussi sensor in question:

At room temperature, I’m getting high resistance readings (18500 ohms or at 20k setting = 18.56).

However, the resistance does reduce when presented to a heat source.

Thanks Dave. Would you recommend the PCB be sent away for specialist repair?

Hi Dave,

Thank you for your response – much appreciated.

No I haven’t, reason being, I measured the mains supply into the PCB from the power cable and it was a steady 240V during the dishwasher working and dishwasher cut-out.
I also checked the mains supply + fuse at the wall socket – all good.
