Thanks for this. It's not something I think I could do, it sounds a bit too technical for me, so will ask my dad to give it a try when he next visits in a couple of days. Thank you for the tip. :D

Thanks for the tip but unfortunately this does not work; I have tried it several times. I have, once again, been trying to get the heating to work for hours now and it just won't fire up the boiler. The green light on the SCR is on most of the time and the red light flashes occasionally to...

Thanks for this but what does 'link out' mean? Is it easy to do? Sorry to sound so dim but I do not know anything about central heating. :D

I tried to start the heating today on many occasions and have only just succeeded by, once again, turning the electric off in the airing cupboard and switching on again - although this often has no effect at all. Before I got it going, the green light was on the SCR and the red light...

Thanks for this. I'll test this theory out tomorrow and will listen for the 'click'. I don't want to turn the heating off now to check because it's a bit chilly in the house and I doubt I'll be able to get it to work again! I'll let you know if I hear anything and thanks very much for...

Thinking about it ... the green light is often intermittent. I notice now (when the boiler is on) the green light is constantly on.

Thanks for this. The receiver does have a green light. I have stood by the receiver to check this (on many occasions) and the red light flashes, then the green light will come on. Occasionally, the boiler will then fire up but often it does not despite the green light being present...

Thank you! We very recently replaced the batteries in the thermostat. The programmer is a ST6400C Honeywell The thermostat is a Drayton Digitat SCR Any ideas? Thank you once again. :D

Hello, wonder if anyone can help me? I recently had problems with my boiler (had to keep resetting it and the blue light flashed constantly) and an engineer fitted a new PCB board. This solved the blue flashing light problem but we still have problems with the boiler. We have hot water...

Thank you Eliteheat, I will follow your advice tomorrow. :D

Thanks. Excuse my ignorance - do you mean bleed the boiler?

Sorry, it's a Worcester Combination Ri :D

We were told we had sludge in system so put some Fernox chemical cleaner in the header tank, after draining system down. Since then, the boiler keeps cutting out - prob because of air lock?

Thanks; we have an indirect condensing boiler. Hope that's enough info.

Can anyone advise how to clear an air lock in our CH system? We have vented the radiators, is there anything else we can try? Thanks! :D

Thank you Gavinda, sounds like that's worth a try. I will buy batteries tomorrow and cross my fingers! :D

Thank you for your replies. Unfortunately, our thermostat is wireless with digital numbers and it's therefore not possible to see if it 'clicks' in and out of action. I put the thermostat in the fridge for a short while and the temp number decreased to 15 degrees, I then put it in the warm...

Hi, I hope someone can throw some light on this: our central heating is working but the radiators are not getting hot enough. The boiler (3 years old) is turned to maximum and the thermostat is turned up to 23 degrees. The heating is fine until the thermostat reaches 17 degrees, the rads then...

Chris, thank you so much for your helpful advice which I will flag up with the plumbers. Far North, funny you should ask about the vent on the soil pipe because I have been wondering about that myself. My plumber did not mention the vent but I understand that building that its a...

Thank you Rich for your time, Hi-Spec also. Not the ideal way to do things I know, but feel it's a slightly better option than using a macerator so fingers crossed and we'll give it a go! :)
