Vokera Compact 28 Gas Valve Fault

[the_ace]

Heres a funny one for ya'll, went to a compact 28 which will not ignite. Its had a new pcb and 2 gas valves as its getting to ignition stage and wont open the gas valve.

I checked for 240v at the board and 240v at the plug going in to the gas valve. I'm left thinking its a bad batch of gas valves as I just put another new one in and it still won't open!

The boiler is getting replaced but i'm curious as to what the problem could be, any ideas?

Did you check the neutral ?

Quite right, which is why I've moved it.

Just a thought.
The green pcb fitted to latter models requires the seperate ignition board fitted as well.
Earlier models fitted with red pcb must be replaced with new red pcb.

Know a few engineers being caught out with this.

Apologies I meant to put this in the private forum, after a lot of swearing and walks to the van I got this sucker. The harness from the PCB to the gas valve was showing 230v at the gas valve end but the valve wouldn't open, I suspected the plug was loose so moved the pins on the valve slightly plugged it back in and hey presto its was back in action!

Interestingly the Vokera tech guy I had on the phone was adamant it was a faulty valve, and he told me I had to have the valve plugged in to check it was getting 240v, I was getting 240v at the plug without it plugged in
