Hi does the boiler have a pump or fan? When these fail and short circuit , the mains will trip
it is a swimming pool boiler, so the pump is outside
Ok , you need to check what is short circuiting. A multimeter on ohms is the best tool for this . is the circuit breaker that is tripping doing the whole system , is boiler pump etc?
Meant boiler , pump etc.
I by passed the circuit that when I found it tripped the circuit , I wonder if it is the temperature control unit ?
When a circuit is tripping it is normally something that has shorted . in my experience that is normally something with a coil, is a motor like a fan or pump , as these are heavy duty jobs . but yes it could be any component. Normally they boiler components are protected by a fuse on the PCB within the boiler . maybe it would be worth taking out the switched live from the boiler , run the system and see if it still trips . this might help narrow things down a bit
Ah but I used a separate lead to by pass the circuit , if the PCB fuse was blown ,it would not have tripped the the mains ?
I willl try as suggested & will come back to you later on.
Ok , you could also do the same for the pump, take the live out run the system etc , to try to track the faulty part down
Hi Toby I tried every possible ways it just trip the fuse ! I suspect the culprit is in the Honeywell gas valve, I wonder where I can purchase the unit ?
