Hi guys, i have had a problem with my backboiler for a while now and its really getting me down. The back boiler keeps locking out. I have had the PCB changed, a new programmer, and a gas engineer look at the system. He says it must be the wiring that is wrong due to a previous mishap. I have...

The boiler does have a 3am fuse on the mains

Thanks guys, i have connected the earth to the mains earth. Cheers

Hi guys, i have recently had lots of problems with my backboiler, although the problems appear to be solved now, i have a query. The boiler is a potterton house warmer with a heating system. The control unit earth isnt connected to anything, its just "floating" behind the programmer, the same...

Well, the electricians been and gone, rewired pump, mains & boiler to programmer. Still the same happening. After he scratched his head for a while, he blamed the boiler control board. It was definately NOT the programmer he said. When he had gone, i had an urge to remove the programmer...

Gas engineer has removed fire this morning if electricain cant sort the problem, then he will come back and have a look at boiler, but is pretty certain thats all ok. Electrician coming anytime soon to re-wire the lot, so with a bit of luck we will be nice and cosy and warm by tea time. I'll...

There is no fan, i have the installation booklet. The heating engineer is coming out tomorrow to remove the fire so the electrics can be looked at. Im going to get a LWC 3 Junction box to connect the mains, boiler & pump to, then connect to the programmer, i have the information booklet for the...

if i replace the fuse, then go and buy a LWC3 Junction box, and connect the boiler, pump & mains to that as on the following link (connection chart section) then there can be no doubt that the fault is not an electrical one............can there...

I have run it by CH&P, if you follow then link above, the last post tells you exactly whats happened, im having a nightmare!!

Thanks. Im really at a loss as to why im having this problem with the boiler locking out (as per link above)

The full story of the problem is here.... http://www.diynot.com/forums/viewtopic.php?p=1135220 as a result of this, i have established that the wiring is correct, i have bought a new programmer, still same problem, this is the only thing left to try. Very stressed as you can imagine.

I have the manual for the backboiler, it is definately a T1H ceramic i need. But what i need more than anything is to get to the route of the problem. Why does the boiler seem to have a permanant live?

Its a T1H ceramic, 20mm, the local Maplins dont have any in stock but im sure there is somewhere local that will have 'em, i got a glass one just to test if it will solve the problem. It was blown by someone who thought they knew how to wire the programmer!!

Im replacing it tomorrow when the gas engineer comes out and takes the fire out so i can get to it. I have been told today in a plumbing forum that it sounds like the boiler is getting permanent live and short cycling untill overheat.What cold be the problem? Any ideas?

what would be the result if a T1H time delay fuse was replaced with a F1.6amp quick bolw fuse in a back boiler control board, could it cause there to be a permanant live to the boiler?

I inherited a Potterton Housewarmer 55 when i bought my house that keeps locking out. It used to do this a while ago but stopped when i had it serviced. Since then, the father-in-law came to install us a wall unit, and knocked the programmer (Lifestyle LP241) off the wall. He rewired it (thought...

it seems that what you have just said, is exactly how it is currently wired - see original post. Could it be a faulty programmer?

there are 10 wires in all, (the one from the boiler is 4 core) & the programmer is set to G. It is a potterton housewarmer back boiler. I just need to confirm which wires got to which terminal on the programer so it works correctly. eg....pump live to ?? pump neutral to ?? etc...
