Baxi Combi 80e - faulty gas valve 5107339

Baxi Combi 80e - faulty gas valve 5107339

GC.No. 4707506

Hot water is intermittent. It goes hot and then runs cold and hot again. The boiler makes clicking noises and the lights on a control panel randomly flashing from time to time. It seems like a PCB Fault but actually it is a harness or a gas valve problem. If you disconnect the gas valve wires there should be a resistance between top 2 pins around 1.5lOhms and bottom 2 pins around 2.5kOhms. Between top and the bottom around 4kOhms. If there is no resistance between any of them then replace the gas valve.
