Vokera compact 25HE switching off and temperature changing?
My voters compact is about 5 years old. It has recently started switching itself off, with the light going red, when the heating is on. If the hot water is on alone, it pulsates hot then cold. The engineer has been in and fitted a new thermo heating value (?) as he believes that the boiler keep over heating. Any idea?
