Re: Bosch dishwasher not heating in some modes

Martin, before I gave up and called in a service engineer I thought I’d try a new Aquasensor. It was only £13.85 with postage and it was dead easy to fit. I’m pleased to say it cured my problem. The machine now heats the water in all cycles again. 😀

Thanks very much for your help, it’s much appreciated.

Cheers

Re: Bosch dishwasher not heating in some modes

Hi Martin,

Thanks very much for your reply.

I took out the main board last night and had a close look at the back of it. I couldn’t see any signs of arcing at any joint or any damaged tracks. I did a resistance check between the component pins on the wide power tracks but didn’t get any strange readings. Some joints looked a little ‘powdered’ so I de-soldered and re-soldered about half a dozen. I re-assembled and tested it again and there’s no change. It only heats the water on the hottest 70 deg cycle. The others are cold.

Is there anything else you can suggest?

Thanks
Matthew
