boilermate 2000/no main lights on at all

hi there im"e an engineer currently working on the b/mate 2000 ,the fault the customer was describing sounded like the potterton suprima board clicking , on investigation it looks like the main board on the b/m 2000 has gone ,there are 3 green lights showing but nothing on the led display,is it the main a.c.b ? many thanks

marky123,

Yes almost certainly as there are green lights but display is blank. I can't imagine any fault other than ACB board failure that can cause this.

I expect the Suprima board will have failed too. They only seem to last about half an hour ;-)
