I have a Baxi Combi 80e. I have an issue that the hot water doesn't run constantly when the tap is on and will turn to cold and then get hot again. The boiler will ignite whilst it's running hot and go out when running cold.

This is actually worse when running the bath tap. Would this be thermostat of some description ?

Hopefully someone can help before I call out an engineer.
