Ariston combi boiler

Hi, my combi boiler has been on summer setting for months now, no radiators or timings, the settings on timings are all on off, so we should only be having hot water but about 4 times in the last two weeks, twice today the radiators have come on, I think after we have been running the hat water, any ideas what is wrong?

Sounds like your diverter valve is passing on the boiler, this diverts the heat either to the rads or to the taps, if its passing through the heating chanel it'll heat up the rads- may also be a scaled up secondary heat exchanger, hope this helps you

Many boilers seem to use a more or less common type of thermister although actual fixings vary. My experience of one of these from another brand of boiler was 670 ohms at 10 deg C and 10 -11 k ohms at 20 deg C

RAds don't get hot anymore


rads not heating could be down to old system ie pipework etc and sludge building up. r there any cold spots on rads? when boiler turning off do u mean going to reset? if so could be over heat prob at boiler . there should be a pressure pipe coming from boiler going to outside if its a combi. if this is leaking your expansion vessel might need re charged as this is where the water will be going.

Ariston Microgenus 27mffi combi boiler


im an engineer and recently had exactly the same thing with this ariston boiler, i found out it was the the 'air pressure switch', this is a switch which is part of the ignition, it works in conjuction with the fan. when the boiler fires up the air pressure switch makes, if its faulty it can break the circuit mid flow and cause the burner to shut down therefore giving intermittent hot water and heating, theres a possibility that the aps tubes may be damaged as well so ensure they'e condition is good. hope this helps you

If the pump is not circulating change it. If the pump is ok you may have a blockage in the diverter valve
