Hi
SIME Friendly Format 80E Combi-boiler - 5 years' old
For month now, boiler keeps cutting out (every few seconds). Hot water taps running lukewarm/cold/lukewarm/cold. Plumber says thermister needs changing. He operated boiler without thermister to test it, and, although kitchen tap ran v hot (constantly), bathroom tap still ran warm/ cold/warm ... (although boiler didn't cut out). Radiators warm, but not great. Can anyone help?
