Firebird 120 no hot water

[mikeho]

I have a firebird 120 combi boiler and no manual.

Cold water, central heating is all working fine.

There is no pressure on the hot water apart from an initial burst, hot water does not heat up.

I have had two plumbers out, one said it might be the pump, the second one has said he thinks it is the blending valve.

Any suggestions or help to source a manual would be appreciated

You can get the manual off the firebird website. If the mains coming into the boiler is ok I would suspect a blocked check valve they tend to break up after a while can be quite a common problem.. easy to check it is the first valve on the cold main into boiler just undo both nuts and remove and check.that would account for loss of pressure,once you have sorted that out and there is no hot water it could be the flow switch or pump
