My Gledhill boilermate OV stopped heating the water, blew the on board fuse and tripped one of the three breaker switches inside the boiler. The gas boiler was showing a low temperature but was ok.
To fault find turned Gas boiler off and on to electric only. (Switch setting) replaced fuse, Reset trip. All seemed to be working. After showering the fuse blew and the trip tripped.
as the hot water call switches on the domestic hot water pump and ‘ a thermostat’ I disconnected the Domestic hot water pump replaced fuse and reset trip. All ok so reconnected pump checked the pump was working ok, it was working ok no problems
Not sure what to check now, does anyone have any ideas?
The circuit board is flashing ok and the correct elements of the display light up for calling central heating and hot water following switching the boiler back on to check.
Anyone familiar with this problem or have a methodology I can follow to isolate the problem. ?
Over temp thermostat? How do I check this?
