Re: Indesit DI620 – Please help 🙂
I just came here to thank you for the helpful information. I was able to fix my Indesit Dishwasher with this issue using the information here. It turns out a zener diode had gone on my timer module PCB as a previous user had said. This must be a common issue with this board.
On mine it was the one labeled DZ02 which can be replaced with a BZX85C 12V 1.3W, you can get these on eBay etc or from a retail store in the UK Maplins (order code QF55K)
I wrote up the process I went through to help others on my blog below.
