Hi, I have an Astoria 2 group AEP.2 and its been working perfectly for the past year.

In the past two weeks or so the element has been cutting out, seemingly for no reason. There is always sufficient water in the tank. To get it work again I have switched it off at the wall plug and/or the unit's switch and I've pressed the element reset button and or turned the little yellow temp knob up and down. At some stage it eventually starts working again but I cant determine which one of the above actions does the trick or whether it is a combination or all of them.

Does anyone have any idea what might cause this behavior?

Thanks,

Andre
