Hello everyone
This time i bought a flat and its got one of the above fitted. When HW is run you get warm water only everything ignites and runs for about 10 seconds smooth then it looks like the gas is pulsing.
When CH is turned on it runs smooth for a few minutes then gas pulses.
On both occasions the fan and pumps run on and boiler turns off and attempts re-ignition but fails then the boiler gives up but no fault lamps come on.
There seems to be a staged gas valve looking from left to right first actuator has no continuity the next 2 have continuity all the time whether running or not.
Do you think there is problem with this valve and is the sequence right to left?
Is it possible to replace the actuators or is it the complete valve? An idea of the cost and labour time for Corgi? Are there any further tests i can carry out to find the cause of the pulsing.
Thanks for your comments.
