Hi, can anyone help. My Boilermate 2000 has suddenly lost power (no lights at all) after I adjusted the timer and I have no heating or hot water. The Potterton boiler panel is also off showing no lights, I believe this is also powered by the Boilermate. I was advised it would be the ACB due to age so off I went and bought a new one as the BM is 15 years old, but until now trouble free. After changing board, I checked the isolating switch fuse and still no lights? I have removed all the additions off the ACB so its just got the live power feed connected and still nothing, what should I try next??????
