We've had a plumber in, he's replaced the circuit board, the termacouple, moved the fan (as it was in the wrong place originally). Now he wants to replace the pump, which he thinks is the reason? But i just can't see how the pump would be the cause...

If the pump is running then I would not suspect the pump at this stage. When the boiler trips out do you get any banging as it shuts down, if so then its circulation problem, some boilers have a pump over run thermostat and it burns out. This is a changeover switching device, it normally keeps the pump running when the system is hot and continues to supply a feed to the pump until the system cools as when the time switch switches off.
If you have no banging then it could be the overheat thermostat which is an interrupter on the thermocouple circuit. The O/H thermostat contacts become tarnished and because of the minute voltage (30 mv) this will cause the gas valve to trip. If all this fails then look at the gas valve Honeywell grey button type is known to cause this problem.
Suggest you change engineer it could be cheaper in the long run, take it he is putting your old PCB back. IS HE CORGI REGISTERED, ask to see his card or ask for his ID No. If your not satisfied ring CORGI 0870 401 2300 or log into www.corgi-group.com

Boiler Could Be Shutting Off On high Limit. At That point Circulating Pump Should Still Be Running Only way To find out if Pump Is Doing it's Job Is To Check Amp Draw On Motor Of Pump.

Hi tasha, you don't say the circumstances in which the boiler cuts out. for instance if it goes over temperature, or blows a fuse or just stops running when the house is still cold. can you put some more information in?. Also what make of boiler, if its a combi and what indicator lights come on when it cuts out.
If the heating is switched on and the pump fails to run the hot water cannot leave the boiler and it will in fact cut out on over-temperature. This can be checked by using a stethoscope on the pump

Pump easily the cause. This circulates the water and prevents boiler from overheating. To be sure, look at the pump when the system is on, remove a plug with a coin-slot on the end, this exposes the shaft of the pump...is it turning? if not, its the pump. If you can (carefully) check the power to the pump....no power.... system on..... very suspicious, but not the pump.

He suggested this because if the pump doesn't move the water in the boiler, then as soon as the water in the boiler is hot , the boiler will shut down because it has reached the temperatuure it has to.

Find out the make and model, ask the supplier for a registered dealer who will have a trained person on the type of machine you have, invariable if there is still a problem that he cannot fix if recognised he will have the phone number to the help desk at the makers factory, other than that this sounds like something for Watchdog, check your boiler for a phone number and model number then phone up yourself if you find it.

if the pump is starting to fail then the boiler will have to shut itself down as it has no way of removing the heat which it is producing.
so he might be right, but to be honest i'd get someone else to have a look at it...

at this rate, you will have bought a new boiler one piece at a time at twice the price. oil, gas or electric boiler? could be a bad ground to the control board fron the thermocouple.

the pump is an electrical device that could cut the whole House electricity.

Something is overheating and causing an overload.Sounds like a bad bearing in something.
