I've noticed that the water pressure on my hot tap has been low lately & while showering the water went hot & cold. Now I have no hot water & the heating light is flashing. Can anyone tell me what the problem could be, thank you?
prsum you have a combi if so check the pressure gage should read 1.5 bar if too low boiler will switch off, need toping up.
