Re: Worcester Greenstar Camray External 12/18 oil boiler.
I have an ongoing problem with the above boiler. When set to work from demand via the timer or when manually switching it on the boiler will not run for any length of time unless the boiler control thermostat on the boiler is turned to max. The lower the control is set the short time it will run then stop. If I turn the control up to max it will run again for a short time then stop, I assume this is the boiler control thermostat shutting the boiler off as if left to cool for a while it will again fire up and run. The boiler itself and the radiators will heat up fully.
Also, about half the times it is supposed to fire up via the timer or the one-hour boost the boiler won’t fire up. It sort of locks out but the lockout light on the burner reset button is not eliminated however pressing the burner reset will start the boiler if the boiler the boiler control thermostat is set high enough.
We had it serviced in August and after testing it was not used again until about three weeks ago. The tank is full of oil, new filled in Sep. I have spoken with the oil company and they say they have no reported problem with that batch of oil.
We had the usual service engineer who services the boiler out to look and after spending some time with it basically giving it another service, fitting another nozzle even though the one fitted in the service hadn’t been used, and fitting a new photocell the problem remains and his conclusion is because of various parts being obsolete due to age, it was installed in 2008 he thinks we need a new boiler. Frankly, I’m not buying that and sent him away.
Being an ex-electrician I have looked at the electric side of things and noted, all the in-house control systems seem to be working and are calling for the boiler to turn on and supply 230V for it to do so.
When the boiler has been switched off by the boiler control stat I have linked out this stat and sometimes it will run and sometimes it it still won’t until it is cooler. I’ve checked the continuity switching of the boiler control stat and it appears to work continuity-wise, as for resistance values I have no idea what is normal values with reference to temp.
I’m going to think it is a control box problem but they are very pricy to just buy on the off chance.
In the summer one radiator was removed, this was done by closing the valves and removing the rad. When it was replaced it was filled gently in the usual manner to remove the air and everything worked fine afterwards and the usual inhibitors topped up via the header tank in the roof space.
I’ve checked around the whole system for leaks and bleed it several times. The boiler has no pressure gauge fitted. I was told by You need a new boiler mate man the pressure was OK. But being an open vented system wrong or right I don’t see pressure being a problem unless due to pump pressure but as said once the system gets running it works fine.
Any advice would be appreciated before I go spending reducing funds on having another person look at it and tell me to buy a new one due to age when I’ve checked and parts are still available.
