Hello
I have a Worcester Bosch 28 CDi combi boiler. It has been running fine until this evening. While trying to get hot water to rinse the kids from a bath - the water would not come up to temperature.
I checked the heating thermostat and turned it down to ensure no heating demand, but the hot water runs for only a few minutes (if that) before runing cold again.
I tried the kitchen tap later in the evening. Again with no central heating demand, the water runs hot for a few miutes, then runs cold - but with a noticable leap in the pressure.
Any ideas what is causing this?
