Dishwasher help - water not heating

Myser

So you've confirmed that it is the relay that is faulty?

They only have a finite number of switching cycles.

You can usually find a suitable replacement from electronic component companies such as RS, CPC and Maplin. They'll probably also be much cheaper than Electrolux!

I couldn't find a way of proving the relay as you can't run the dishwasher at the same time as having access to the PCB , and a search on the Internet didn't show any suppliers other than Electrolux , without me knowing the exact specifications I needed.

But if this works it is still cheaper than a new dishwasher - and if it doesn't I have 2 water heaters and a relay to sell on !!

Thanks again Myser for your suggestions with this , especially about being able to get just a relay (rather than full PCB) - new relay arrived over the weekend , and once I had replaced it for the old one on the PCB I now have the dishwasher working properly again with hot water :j

I spoke too soon......

After several good washes it is back to not heating the water

I'm wondering whether the relay was actually correct for this model - and interestingly they are shown as no longer available on the Electrolux website.

There are 2 markings on top of the relay relating to current :

7A 250V ~
12A 250VAC

Anybody know which of these is the current that the relay can pass through when doing the heating ? If it's the 7A then it's probably blown as the heater is 2kW (so 8/9A) ......

Thanks

Myser

Can you post a photo of the markings on the relay.

I've not posted pictures before - see if this works.

Hmm - I just have a red x when I look at my reply - is there a preferred way to post photos ?

I'll try from photobucket.
