Worchester bosch 25si RSF water heating problem

[lestolley]

My worcester bosch 25si RSF gas combi boiler has a problem with hot water? It's sometimes only warm. I notice when the heating is off and the bath is being filled the radiators start to warm up. is there a diverter valve on this boiler or some other change over mechanism?

They do have a water valve assembly, this may have something to do with it. It is a twin pipe HE I believe.

I don't know Dave, i'm not conversant with new boiler technology if it's not got a three way valve i'm a bit lost, but it's getting on the wife's nerves because she likes HOT baths not warm ones, any suggestions on how to fix the problem would be appreciated.

No three way valve, so it's probably the flow switch, which when operated will shut down the heating pump. Does the red hot water light come on when a tap is opened?
