Possible ACB failure?  Empty Possible ACB failure?

Post  Levi1970 Fri Feb 20, 2015 9:57 am

Our boiler (GlowWorm 40FF) stopped working last week. After some investigation I discovered that it was no longer receiving a demand feed from the BoilerMate2000.
Looking at the BM2000 and reading other posts on this forum I feel the ACB (PCB) has developed a fault and requires replacing.
All the fuses appear ok, the red LED display is not working and all 3 green LEDs are lit.
If I wire up the boiler to a plug socket and turn the emergency knob on the BM2000 to either position 1 or 2 the whole thing seems to work ok, all be it on constant.
My thinking is that the ACB has died and is no longer demanding hot water from the boiler. Please advise.
