Alpha Boilers Guide

Hi

I have an Alpha HE  boiler model CB33 yesterday a yellow/orange “B” lamp started flashing. I restarted boiler 3 times, no success. It’s making some loud noics! Anyone an idea what is wrong and how to solve it?

Hi Nathan

Per manual B lamp flashing means ” restricted flow or a pump fault”. If it makes loud noise it is pump fault almost for sure. You will need to get the pump replaced. As it is a bigger job, you may want to have a specialist doing it rather than yourself.
