I have identified a 1/4 broken bridge rectifier (RC202) on the control circuit board. There are two of these and I will replace both. Hopefully this will fix the issue

The fix will need to wait till the weekend though ..

Yes it did. Both rectifiers have been replaced (the broken one and to be sure the other one too). Thanks for asking
