Re: Zanussi ZDT6255 5-beeps error (Motor fault)

I tried to post more details about where I’d got to with this problem yesterday, but the forum logged me out and I lost it all 🙁

In short: I found that the unit came back to life after I’d tipped it back to check the impeller… However, I discovered that the outer manifold was leaking… The screw thread was snapped and it couldn’t be tightened to seal the O-ring.
I’ve now replaced it with a new manifold.

While I was investigating the leak I noticed that the machine wasn’t heating. After confirming that the element is okay (reads 24 Ohms) I checked the PCB and I’ve found that resistor R8 has split in half and R9 is burnt out.
These two resistors are on the tacho circuit and as I’ve read that it won’t heat without a working tachometer (I’ve checked the tacho itself and it correctly reads ~220 Ohms) I can understand the failure to heat.

Unfortunately, the resistors are too badly damaged (see photo) to read properly 🙁 R9 is ’10?’ possibly ‘104’ but as the last number is the multiplier it’s pretty critical I get it right!

Is there anyone on this forum who can tell me the correct values of these two resistors?
I’m going to ask Zanussi tomorrow but I’m not expecting much success…
