Hello all,
New here so please forgive my ignorance. I have a Main 24 HE combi boiler and it’s playing silly bugg*rs. When given power it runs constantly, providing both heating and DHW. We have to turn it off at the selector switch when we don’t want heating/hot water otherwise it just burns gas.
Have read through the manual and following the trouble shooting I have:
The only other thing the troubleshooting says to do is clean the DHW heat exchange but I can’t see that making a difference, can you? Maybe I’ll try it if I get time over the weekend.
Has anyone experienced this fault before? Or have any clues what could be causing the issue?
Any thoughts welcome,
Thanks

Have read through the manual and following the trouble shooting I have:
- replaced the timer clock, no joy
- replaced the PCB, no cigar
- removed, cleaned and tested the thermistor, no luck
