SOURCE: Central haeting ok but no hot water

If the valve runs at other times, the valve is OK. you have a relay somewhere that is not sending signal to the valve when in that mode.

Trace down all the relays for that cycle and check voltage going int, coming out, and to see if the coil is enrgised.

SOURCE: combi boiler no DHW

if the boiler fires when the tap is opened then the diverter valve is working ok it must be a blocked plate heat exchanger which is the stainless steel rectangular block inside the boiler connected to the pump and the mains cold water.
it will be blocked on the central heating part probably with black scale. it is possible to clean out but sometimes it is better to just change the plate. but remember to flush the system as well or the same thing will happen.

Ideal icos 18 fault code HF


According to pages 47-50 of the install guide, section on FAULT FINDING, the alternating H and F indicates Flame Detection Short Circuit Error. Actions are: Remove flame detection electrode terminal from PCB. Test for continuity between 2 terminal pins? If YES, replace flame detection electrode. If NO, replace PCB.

Water to hot for gas boiler boiler gos off


It could be dyslexia, but I think you want to know what may be wrong with your boiler in this case!
This is a VERY old design. The diaphragm is on the water section, this operates a switch to turn ON the pump, and a further device causes the diverter valve to divert boiler water from CH duty to HW duty.
From your description it appears that the boiler is shutting down on internal boiler water temperature (too high), your 'briefly too hot' HW symptom may be caused either by the boiler side of the secondary heat exchanger being blocked/caked in sludge, OR the DHW side of it being scaled. Either way a new or replacement (descaled) secondary heat exchanger MAY inprove things. It's not easy on these old clunk-pots, and EVERY disturbed seal will subsequently leak, so get a good supply of o-rings and fibre seals before you start ("you" being the competant fitter you employ)

I have just tried to run my ferroli optimax 31c boiler. The boiler fires up, but then displays a d2 message and the radiators do not heat up. Any ideas what causes this problem and how I can solve it...


D2 is not a fault what that means is delay and 2 refers to CH which means the boiler has gone into standby mode. you need to check that your CH circut is open, there is a filter on the return valve into boiler make sure this is not blocked. If this is blocked the water is just going though the boiler by-pass so then the boiler thinks its up to temp. hope this helps
