Potterton performa 24 - no hot water

[artomlinson]

I have a potterton performa 24 combi boiler. This morning I discovered that there is no water coming out of any of the hot water taps in the house. CH is working fine and water was fine yesterday but today there is nothing. There are no obvious warning lights on the boiler itself and the manual has been no help. Can anybody give me any ideas what might be the problem?

Thanks

yes have the water main is turned off ,have you got cold water ?

I have cold water as normal but nothing from the hot tap. The water main is still on - do you think I should switch it off?

If the boiler is in a space that is unheated, the pipes could be frozen. Check incoming water to the boiler. If they are not frozen then there is a blockage in the heat exchanger or the screen before the valve.

if you are getting cold water out of the tap and nothing coming out of the hot logic would say a blockage is there perhaps a frozen pipe try putting a hair dryer on the pipe where or if its stone cold ,good luck
