Zanussi ZDT21006FA Dishwasher no heat 91153920500

Hi,

I had a call to look at this dishwasher this week, the customer said it wasn’t heating. I pulled it out and checked all the usual suspects, the heater and motor tacho but they all checked out fine. I ran the dishwasher to see if I had any power to the heater and it started to heat and worked perfectly. I have since had a call from them saying it hasn’t heated since. Anyone know of any intermittent heating faults on these?

I had one where it had an intermittent connection to one of the thermostats on the element (broken spot weld).

Thanks, something to look at.

We have had a number of these dishwashers with a reported no heat fault and when the tacho is tested it seems OK. And if the element continuity is correct.
We always replace the tacho. It has worked every time. Beko coil part number 372205506 fits.

Excellent, I will check that out too.

Just thought I would update this. I called back today and the tacho had gone, fitted the Beko tacho and it’s all working fine again.
