Hello My name is Ian ~ I am not on the site constantly so please be patient whilst waiting for responses to you queries


Hi Ian


Can you help with the problems I'm having

Dales-Electronic :

OK as you will be aware there are two types of fault code with this boiler A type which cause a full boiler shutdown and F type which doesn't. A03 is either a water circulation fault (check that the circulation pump is turning) or alternatively it indicates that the circulation sensor cannot register a heat change, has come adrift from its clip or finally the sensor is faulty. I attach a link to the service manual which gives you the fault finding procedure to help you locate and rectify the problem. Kindly understand that until you have cleared this A fault nothing will work ~~ ~~ Ian


Thank you for your help Ian
