Ideal Response 120 combi - flashing LED and no heating
On an Ideal Response 120 combi, does anyone know what a flashing "Central Heating" LED (behind the cosmetic cover) means? The symptoms are the boiler won't light if the CH is on though the pump pumps the CH water OK and the DHW works. MTIA -- bof at bof dot me dot uk |

The boiler lights OK when it's DHW, and the CH doesn't get hot even when the DHW is running. I'm sure the pump's OK as when I switch off the DHW there's a couple of seconds surge of hot in the CH. -- bof at bof dot me dot uk |

Firstly I'm sorry if I put you on the wrong trail here. You may well have a model that has not yet eaten its heat exchanger (yet). I don't have a manual for this model - what does it say? -- Ed Sirett - Property maintainer and registered gas fitter.

Check the pressure vessel charge. This goes flat quickly on these models. Check the system pressure. It has a low pressure switch, so if pressure low problems. I'm not sure if it also has a CH flow switch, if so check this. |

In message ews.net,
Doctor Drivel writes Check the pressure vessel charge. This goes flat quickly on these models. Check the system pressure. It has a low pressure switch, so if pressure low problems. If the pressure's stable and, from prior experience, if the pressure does drop it won't light the DHW either. I'm not sure if it also has a CH flow switch, if so check this. Thanks, the CH light flashes continuously, irrespective of whether the CH/DHW/stat switch etc. are on or off, which seems to imply that there's an internal fault of some kind before attempting to run the CH. -- bof at bof dot me dot uk |

There's a reset swtich somewhere IIRC. First thanks for all the suggestions. The cutout switch I know of is on the bottom right, but if that pops out it shuts off the DHW and the CH. This fault is something specific to the CH. -- bof at bof dot me dot uk |
