hi
well if its like mine and the 3 others that ive repaired it can be wedged by a strategicly placed piece of wood.lol
the worcester boys should have put a new board on it though,and they are guaranteed to fix it,play hell with them that its still not right,dont pay again for them to NOT to fix it.
it should also be guaranteed for 12months after they have repaired it.
you need to remove the bottom cover ,3 screws,between the cb and the front plasic fascia near the middle,insert a piece of wood so that its a tight fit and very slightly pushing the cb inwards.
please make sure electrics off before doing this mod.
mines lasted over 2 years by just doing this and the others have lasted 3 years+ before acting up again.

ok thanks evolu. by reading what you have told me to do it sounds as though maybe a solder joint on the cb may have failed and the slight bending of the cb enables the solder joint to close up and operate normally, anyway i will try it and i will post back and let you know what happens.
thanks
thanks

hi,give it a try and see.it worked for me and a few others.
you could remove the cb and repair but its a bit of a pain on this model,and whilst it is out you may aswell replace it for a new one.
a piece of wood is free

UPDATE:
Cleaned the system and refilled but not put inhibitor in yet. Still having issues as described in previous point with continued sparking even though pilot is lit.
Anyway tried evolu's solution with a bit of wood and doesnt work for me, so now im left with a dodgy circuit board. Does anybody know how i can make sure it is the cb before i fork out for a new one?
thanks

Because the flame detection is high impedance its very susceptable to any leakage path to earth!
Clean the insulator on the flame detector electrode as well as measuring the conductivity between the tip and the PCB.
If you are burning candles near the boiler then you might have fine carbon on the pcb in the area of the flame detection circuit.
Inspect and if necessary wipe with dry soft tissue ( and see if any marks appear on the tissue ).
I once went to a Sri Lankan Temple where they burnt camphor and the smoke from that had stopped the Worcester boiler from working.
There is also usually a high resistance resistor on the PCB in series with the flame detection electrode, often 1 Meg. These sometimes go open circuit or very high resistance.

thanks tony.
can you please explain in a bit more detail on how to go about doing this. And in relation to the spark whereabouts is the flame electrode
can you explain whereabouts on the pcb resistor is and would i need a megger to check
thanks[/quote]

I am sorry but I cannot give specific details on jobs which must be done by a competent engineer and normally one who is gas safety registered.
Use a megger if you want to, its your boiler after all, but that is likely to damage the PCB !
If you cannot do these jobs safely yourself then the obvious answer is to get a professional.

thanks again tony.
got the "professionals" in from worcester twice at a total cost of £440 and it still doesnt work correctly!
well they should have left you a report on both occasions with a list of parts replaced, so what did they do? I would get them back if its less than 12months since they came.
