Gaz, BG will come out to non-BG customers, BG customers get a £12 discount. Cheers, Gary.

Decided to buy the pcb over the counter (£182) as didn't want to wait any longer without proper heating and water. Got home and found that my son had got it working by switching prog to on and it starting first time on 'reset'! Then I saw a post on another forum about BG doing boiler repairs...

Hi to anyone still interested (lol) I am definitely getting around 220V DC across the red and black to the gas valve; 478V AC! Honest!! The ohmic values of the valve solenoids are approx 1350 and 2800 (very similar to that suggested by ChrisR. Saturday morning, tried a few more joints...

Chaps, I know mains is ac. I was expecting 300V DCcos that's what the manual says the reading should be!

Hi again. Whilst dormant the voltage across the gas valve was zero but as the prog kicked in the pcb sent 217V - 219V dc to the valve. I was expecting 300V dc as per manual. Is this confirmation of anything? Maybe not enough oomph to open valve fully? It's worse now as it has to be set...

Hi again. I had to reset it this morning, not particularly cold. Put it on permanent 'on' as we got up late! I went out a short while ago (boiler been fine since I reset and put 'on') and with boiler at rest I put meter across the gas valve. As it opened it fluctated between 217V and...

Hi All. - UPDATE - This afternoon's setting went in to lockout! On going out to check I can actually see the spark every time of its 8 attempts! :? Possible gas prob? :( It kicked in when I thumped the bottom of the boiler a few times quickly though probably coincidence. :roll:

Hi gaz. Yep, thanks for that. I suspect the pcb hence the resoldering as it's a darn sight less expensive than a new one! So you reckon my (boiler's) symptoms point to the pcb for sure? Cheers. All the best.

Hi All. I’m an appliance engineer not a gas fitter however I hope someone is able (and willing!) to help/advise. :( I have a Potterton Suprima 80L boiler which is suffering from intermittent lockout. I’ve reflowed a couple of joints on the pcb and changed the electrode (will try more joints...
