Firenzi DW930/1 replacement PCB

[Jifl]

Hi,

I’ve got a busted Firenzi DW930/1 dishwasher (a Whirlpool in disguise) – the circulating pump started activating only sporadically, and now doesn’t at all. But it wasn’t the pump: with careful multimetering, I’ve traced it back to the IC on the PCB, and is beyond simple repair. A replacement PCB is £146 all-in – only a little short of a brand new dishwasher from Argos!

Is there any way to get a second hand PCB, e.g. from a dishwasher that was beyond economic repair for a different reason? Does anyone know how to get one, or if you’re in the trade, even have one around? I’m even prepared to desolder the IC from a board that is broken in a different way, and fit it to mine.

The PCB can also be found in a Caple DI414 or Whirlpool APDW/2/2

Any help gratefully accepted! Thx.

Hi

The most common problem you will have is that this dishwasher will have a ASKOLL type wash motor fitted.This motor will operate sporadically and then totally fail due to its design.

I would very much doubt if the IC is the cause of your problem.

Yes, I’d seen the helpful page about that, and indeed the Askoll motor had already been replaced. But on closer investigation, if I short together the right lines on the PCB, it runs fine. Two transistors between the IC and the edge connector are also fine. It’s the signal from the IC that fails to get generated (and there is perfect connectivity from the IC pin onwards).

So this time I’m afraid it is the IC.
