Boiler problem

[ferguson9]

I bought my house in August but have been doing it up therefore have not been living in it. About 2 weeks ago I tried turning the central heating on to check the boiler was working and after about 5 mins the radiators were definitely warming up. I wasn't sure what I had set it to so to ensure I hadn't set it to be on all day I turned the whole boiler off.

I now want to set the boiler to come on at 10pm - 7am to ensure the pipes don't freeze with the cold weather, therefore I tried setting the timers for the central heating. However, I am getting the error "C1". I have read that this means the fan speed is too low.

Also, if it is any relevance I have had an electrician working on Wednesday and Thursday starting a complete re-wire, although I think he has only been chasing so far so don't think he has touched the fuse box or anything.

Does anyone know how I fix this? Preferably without getting an engineer out.

The boiler is a Worcester Greenstar R30HE

Hope someone can help.

Thanks!

It's a fault for which you most likely need an analyser to solve it, time to find a good repair specialist.

c6 means the fan is running slow, c1 means there is a fan fault! You need a new fan. WBosch do a fixed fee of £210. maybe ring a boiler repair man in your area. If his quote is more you know your options!

C1 does not always mean you need a new fan, likely but not surely.

yes mate it does. Its the only fault that covers it, unlike ea that covers a multitude of sins! The board knows there is a fan fault. i'd bet the boiler doesn't run at the moment.

and ben why would he need an analyser for a fan fault?

 

[bengasman]

Because this model boiler needs an analyser for fan setup according to the manual.

sorry to be pinicky but you set up a gas valve not a new fan. the pcb controls the fan khz, you cannot affect it. You can only set up the gas/air ratio via the gas valve.

If you have a c1 fault it relates only to the fan, not the gas valve. You replace fan and then check ratio and adjust at the g/v.

.... You replace fan and then check ratio and adjust at the g/v.

I wouldn't know how to do that without a fga
