I have found this question which i need an answer to please:

Glow worm 45/2 back boiler burners ignite for about 2 mins then go out?
my glow worm roars into life for about 2 mins then cuts out the pilot light is still lit but i get nothing more from the burners.

Someone had the same problem and solved it by checking the overflow in the loft, as the ball was rusty and there was no water in it, however i have also checked mine, and it is full of water and the overflow ball is ok as well, so what can any other problem be.

Someone has even mentioned they changed the thermostat, and that did not help with anything.

Any one out there who can help me?

check your pump it might seem as if its spin but the shaft can break

Well finally sussed it...the pump was under the floorboards next to the chimnney, and was seized, so have ordered a replacment as is faulty.

Stupid place for a pump, but then again maybe thats the way people worked 10-15 yr ago.

plenty of water in tanks, and hot water is fine which is on same timer as CH, both been put on constant just to see if it it fires up, but it doesn't, so am now thinking either it is something to do with the CH tIMER FAULTY, or deffo the PUMP
wherever that is !

I just been pullin my hair out, trying to suss where the bl**dy pump will be , but its nowhere to be seen.

What do you mean by gravity fed craig ?

cant see it being under boiler..make sure there is plenty water in the 2 plastic tanks

thanks for your patience, i have checked both tanks, one which is above the water tank in the bathroom, which is full of water, its a big black rectangular plastic box with water, and then i went into the loft as two pipes were leding upstairs, and once i got up there, there was a minitaure version of the same black plastic water tank with the big orange ball, overflow kind of thing theres aswell. No sign on any water pump at all, as my friend told me there might be somthing up there which will have a reset button and that would be the pump, but no luck.

Would it be under the heater/chimney front. I know gas valve is there as i have googles an image of it, but cant find an image of a water pump for the model i want, so i can at least see what it looks like.

check you tanks in the loft and make sure there is also water in them if you cany find a pump..it may be gravity fed

craig, February 2008

i have checked the hot water tank which is in the bathroom, and there is no pump anywhere, believe me i have looked everywhere.
I have a feeling it is under the room heater where he boiler is coz its one of these very old back boilers that is installed in the chimney

Have u got a link for me so i can see what it will look like for this type of model boiler ?

b1ggz, February 2008

where will be the pump on these systems, as i have looked everywhere but cant find it, what will it look like, sorry if thats sound dumb, but that is a very old system , appreciate your help

IF ITS ONLY RUNNING FOR A WHILE CHECK THE PUMP AS THE PUMP MAY BE FAULTY. TRY TURNING IT UP AS ITS GOT 3 SPEEDS ON IT IF IT WORKS I WOULD STILL REPLACE IT. LET ME KNOW IF ANY OTHER PROBS
