The central heating works ok.
When i run the hot water tap slowly the boiler will not light. The ta has to be on quite fast for the boiler to ignite therefore the wate runs quite cold, turn the tap on slower for the water to warm up an the boiler shuts down.Any suggestions thank yo

Diverter valve
Whilst the diverter valve is at the bottom of the trouble for many type of combi faults, in this case I think it is a classic case of growing insensitivity to the DHW flow. Odds on this is a boiler which uses a diaphragm type water flow detection, and the said diaphragm is fragmented.
