Hello I've just seen your posts whilst trying to come up with a solution to my in-laws boiler problem, it sounds exactly what is happening to their boiler! Did anyone get to the bottom of this in the end? I've replaced the temperature probe in the hope it was that which kept turning the heating on constant but it's still firing up

The pin comes out when we turn the hot tap on and retracts when we turn the tap off, the boiler remains lit at all times. I tapped the microswitch a couple of times and the boiler went off for a couple of minutes and the came back on again. I don't know if we should try replacing the micro switch or the diaphragm, their boiler is an Ariston EuroCombi which approx 8-10 years old. Apparently the diaphragm may have been replaced about 3years ago.

Any suggestions or useful advice would be much appreciated!

Many thanks

Hi. Seen your post in diy not about the ariston boiler problem (I know, in 2007) A bit rotten nobody helped you out with an answer. Iv'e got the exact same symptoms. How did you solve the problem, if you dont mind me askin.

Hi, Sorry to bother you, but I found your post ref your combi boiler from 2007 where you were getting your heating coming on when you wanted hot water. We're experiencing the same symptoms with our A23 MFFI now am are wondering what your problem was in the end and how much it cost to fix? Also was it something you managed to do yourself or was it a case of having to call an engineer out for?
Once agan sorry to pester but would really appreciate knowing as like yourself would do myself if at all possible
Many thanks for taking the time to read.
