sound in radiators, pump constantly on?

disconnecting all the connections on the pcb, and then reconnecting it.
that often works for various makes of pcb.

Ormus: would it be worth getting a plumber in to try this method first, before buying a new pcb?
And if so, what sort of costs would be involved?

Thanks:)

You don't want a plumber, you want an RGI (Registered Gas Installer).

Yes, forgot to say, the plumber I used last time was 'gas safe registered'. Thanks for pointing it out for other users, though.

just bumping this, thanks

I bet its just a sticky relay - the PCB can probably be repaired for a few quid if you know someone who's handy with a soldering iron.

Unfortunately I'm not 'handy' and don't know anyone who is.

Which is why I'm interested in learning if it is worth trying the tip from Ormus of disconnecting and reconnecting the old one first, and how much a 'professional' is likely to charge.

Still having problems with the pump and would like to get it sorted asap. I'm abit reluctant to fork out hundreds on this without knowing it is definitely the pcb though.

I've read a few threads which mention things like the 'control thermostat' and the 'motorised valve'. Being non-techie I don't understand any of this, though:o

So, I suppose my queries are:

How do I find out that it IS the pcb at fault?
Would I be better buying a 'recon' pcb from ebay, if still available (mentioned in an old thread)?
Do I need a boiler engineer or gas-safe plumber to fix it?

All answers appreciated, thanks:)

The pump has now started to come back on again at times, after it has stopped.

I have never had to 'restart' the boiler though which gets mentioned on other threads, it is just the pump which keeps running even when the hot water and ch controls are set to 'off'.

The boiler also makes occasional noises - this seems to be not long after the controls are switched off - though I've not been close enough to tell what or when yet.

Is it safe to keep the boiler on, with pump going, until I manage to sort out who to get in (that no doubt will be more fun and games)?

Thanks

If you get a professional involved, don't waste money on Ormus' tip. It is no reflection on Ormus. I would follow his tip myself - it is half an hour which stands a 50-50 chance of curing the problem. But if you get a professional in, you should spend your money on a fix, not on something with a 50% chance that you need to call them in again for a proper fix.

Thank you for the advice dvardy.
