Most likely Pump or Diverter Valve.

Although its electrical I'd guess the Heating Engineer would sort it , and service boiler at the same time .

Do you know what system you have, is it a combi, system boiler, standard boiler with water cylinder and wet rads etc, 3-Way diverter or 2 1-way for heating and hot water.

Plumbers normally ask electrician to tell them which part is the issue before they change it although electricians will do it all.

its a ideal classic wall mounted, fanned, balanced flue gas boiler

As Deke said, a heating engineer will be able to fault find and replace failed part, and I bet it's either pump or diverter valve, small chance it could be gas valve but doubt it.

I have known a pump that's been off all summer seize up then throw mcb, unscrew little plate in centre of pump and see if it turns freely with a screwdriver, if its a new type of pump with small plug, un-plug it and see if you can power up, if not best let the heating guy take a look.

main concern is sparking fuse box..

You have a short that is why the trip is tripping should be fairly easy to diagnose by a competent person.

Well from experience i think an electrician should be your first call. As an example this week i have had 2 such call outs after the plumbers had changed the pump, valve, stat & programmer. They havent got a clue so throw part after part at the problem. An electrician will test section to find the faulty part. On my two jobs both had cable faults, one was burnt behind the flue & the other job a pvc/pvc cable was buried under the patio had a 95% short live to earth. But as normal the plumber had changed & charged for every part in the system except the boiler. The electrician may be able to change the part himself or you might have to call a plumber in.

Very true Slips I did say a competent person not many plumbers are competent.

get the cable meggerd first, will be cheaper than calling in a plumber to change the boiler, then discovering the cable is at fault
