no water from hot taps

[johnk]

I have no water coming from my hot taps. I have a Combi boiler which seems to be OK with no fault lights lit, the central heating seems to work as normal but the presuur goes really high when I use it. There is plenty of water from the cold taps. Anyone any ideas?

there are valves underneath most combis where the pipes come out,maybe the valve for the hot water is turned off and thats why you cant get no water through the taps. as the water warms up in the heating pipes the pressure increases,as long as the boiler does not empty itself of water through the safety overflow pipe it should be ok.

If the pressure is too high, the boiler won't heat the water for safety reasons
