Hi all, about 6 months ago our Potterton Suprima 50 Boiler failed to ignite and went into lockout status. I performed a few checks which pointed me to the gas valve itself. I left it over night and 'tapped' the gas valve - et voila it burst back into life.
Last week the same thing happened again but now it will not ignite whatsoever. I did a few checks on the valve and discovered that coil 1 resistance is 1.3k Ohms however coil 2 is getting no reading. I assume that therefore it is open and possibly the cause of the problem. On ignition sequence I am measuring over 300 DC going into the valve however I did also replace the PCB just in case it was not energising the valve. The result is the same. Oh, I am seeing a spark from the electrode and also replaced the red lead.
I would appreciate it if someone could check my diagnosis and give me an idea of what sort of labour charges I should be paying to have someone fit the valve.
Thank you!
