I have a problem with a 924 combi boiler.
When drawing off hot water, the system works fine for about 10 - 15 minutes and then shuts off completely under the control of the overheat thermostat at the top of the system. I have to re-light the pilot light and then the hot water will function for a little longer. An absolute pain when you want a bath.
I have tried replacing the overheat thermister but it does not help.
The central heating side works fine.
Can anyone help?
