My Glowworm economy plus 40B, fires up OK from cold when calling for heat but main burner goes out after a few minutes, have checked thermostat and power to gas valve soilinoid both OK when calling for heat. Do I have a faulty gas valve or soliniod?
The gas valve solenoid coil went high resistance after a few minutes use causing the gas valve to drop out, changing coil fixed the problem

Have you checked the header tank is full of water.The boiler will be shutting off as a safety measure if the tank in the loft is empty.If it is empty push the ballvalve down,the coil will refill with water then the boiler will refire up.
