Omega odw717x dishwasher doesn't heat water

Hi,

we have a Omega odw717x dishwasher that doesn’t wash properly. The Cycle finishes successfully but when finished the dishes are not cleaned and the tablet is not dissolved and it’s not hot inside like before. We cleaned filters , water pumps and drains fine.

When we cleaned filters and inside the filter place, it worked 2 times but it stopped working again.

We opened the dishwasher from the bottom to look for a thermostat as we thought that might be cause but we were not able to find it.

I don’t have a photo from inside of it now but I can take if that helps.

Any ideas and help appreciated.
