My Volkera Compact 25 boiler has a red light on. I increased pressure from 1 to 2 and reset boiler. It flashes green then turns red again. I have tried to reset twice. The heating is on when I do this. I have a young child in the flat so want to get the heating working asap. When i reset i can hear boiling water noises then red light comes on and it all goes quiet.
Hi . does it do the same for hot water?
Please give me as much information as possible , please so I can make a proper diagnosis
sorry don't know what you mean by this? should i turn on a hot tap and see what happens?
ok done that - left running for 20 seconds. red light still on, no change and no sounds from boiler. the heating is still on at timer. pressure still at 2.
Pressure is fine. Did you reset the boiler before running hot tap?
no. should i? and should i turn off heating at timer switch?
Yes try turning the power to boiler off , then back on , then run hot tap, thanks
and switch off heating at timer switch?
one more thing - when i switch off boiler at dial the light flashes green. mean anything? i've switched off heating at timer.
No. Its normal
Does the Hot water work ?
no hot water. and red light back after 20'ish seconds
it sounds like the boiler is trying
Please understand thus may take a while. Even in front of the boiler it can take a while to diagnose a fault , thanks
Can you hear a fan running?
that's fine. i just hope you can help.
fan? not sure. do you mean after i've switched on and green light is flashing? Maybe.
Could you hear a fan running and sparking noises as though the boiler is trying to light?
can i just check i am switching on OK? With my boiler there are 2 dials on front - 1 for hot water and 1 for heating. i turn the heating dial to off (it gently clicks) wait 30 seconds then turn back to about 4 (our of 10).
should i try again and figure out noises?
Yes please. But can you turn the whole power off at the switch , then back on .then listen for the sounds the boiler is making . can you hear the fan running , ignition sparking? Thanks
oh, is there another switch other than the dial on the front? i haven't been able to find anything else. any idea where it might be?
It could be beside the boiler or where the programmer is , if its in a different place to the boiler
i'll go and look
i can't find another switch. it's not with programmer and not on boiler. do you have a picture of my exact model so that you could tell me where it is exactly?
That's ok . if you do it how you did it before with the boiler switch , but is the hot water working?
ok. so switch off, wait for 30 secs, switch on then turn on hot water. and listen for sounds.
so perhaps its a fan that starts (it sounds like the regular boiling noise) with a faint electrical sounds, then when you expect the boiler to kick in there's just a gurgle of water. it did this twice. then red light, then lots of gurgles.
Ok . I'm sorry to say its nothing that can be sorted tonight . the fan and or air pressure switch needs replacing . these can be tested with a multimeter. Do you have one?
i have no idea but I would say no (hubby is away and naturally he kno
'knows' the tool box. what should i do tomorrow if we don;t have a multimeter?
Is your boiler under warranty?
Do you know how old your boiler is?
