Suprima Gas Valve

[mfgs]

What readings should I be getting on a suprima gas valve when its trying to ignite. I remember from before it was DC voltage but I cant remember the figure.

I think it is 300v DC across red and black wires.

:iagree: 30vDC :iagree:

300v dc?

I was getting 220v DC when it was sparking but the gas valve was not opening. Just trying to see if it is a gas valve of pcb issue. I tried a resistance test across red and black and it was showing open circuit so guessing the solenoids are knackered as there should be some resistance.

Sounds like gas valve if gas supply is OK.

Yeah got gas to the inlet, just wont open. Just wanted to make sure its getting the correct voltage from PCB for it to open. Im pretty sure its the gas valve though.

Concur, although suprima has bad reputation for PCB. Has it been changed for the updated one? Advise you to speak with Baxi/Potterton to confirm, gas valve looks the best bet.

Yeah it already has a new pcb, but that doesn't always mean its a decent one lol.

No what you mean, looks like gas valve though.
