Hi,
Having problems with hot water flow. Water runs hot for 30 secs then cold for 30secs and sometimes trips the boiler. Sensor was showing over heating boiler.
Had halstead engineer in this morning - changed PCB, checked pump but still not working. He thinks there is a blockage somewhere in the system however, have bled and checked all radiators and they get to varying temperatures but are not very regular.
Please help!
