I have a baxi instant 105e combi boiler. often the pump continues running even there are no taps in use. The water gets extremely hot, this does not effect the heating. If i switch power off then back on everything is fine for a while (it happens once every 5/7 days). Boiler is 4 years old.

Ricardo thank you for your response but the pre heat is switched the lowest setting but the boiler still gets very hot i.e. all red lights are on.Tony.
