Hi,

I have been to have a quick look at this machine today. Customer complained of no heat.
I started the machine going on a 35quick wash and within about 2 mins of the cycle it drained and then started to fill again and did this about 3 times before stopping all together.
Next I tried it on a pre rinse cold only and it worked fine.
Then I went for the 60 wash and again it worked fine whilst it did the pre rinse but as soon as it started on to the wash cycle it ran for a few mins and drained and then started to fill and wash again.
Im thinking there is a problem with the control board but just wondered if anyone has experienced this before.

Thanks,
Ray
