Hi . does it make any sounds as though it tries to start up?
Is, does the fan run?
There a quite a few things it could be at this stage. , internal fuse, overheat stat , PCB , fan . need to work through them
If the pump isn't running then could be flow switch isn't operating ,check to see if the pump is running
Ok .if the pump didn't run the flow switch won't operate and you'll get a no flow fault . can you check to see if you have power to the pump ?
Yes , it is going to be pump or flow switch . do you have a voltage tester or multi Meter? What pressure do you have?
Ok . check the internal fuses,
Also if there is an overheat stat that need resetting ,press in type
If pump has gone ,short circuited it could have blown the fuse
It will definitely have one . but sounds like the pump
One thing you could try is bypass the pump by try to operate the flow switch by hand and see if boiler tries to fire , ypthis would confirm its the pump
Ok . it could have overheated for a reason . either. The temperature sensors for heating and hot water could be faulty or the domestic heat exchanger could be blocked
Did you mean the central heating iusnt working ?
Hi. I've got to go and look at a job be back at 4. Check the diverter head is operating .takeof f head and check for movement
