Faulty Boiler Pump?

Hi, I have a BoilerMate A-Class 185 OV and the other day came home to no hot water or central heating. On removal of the cover I notice that the main board MCB had tripped and also spotted that the 3.15A slow blow fuse on the PCB had blown. I tried replacing the fuse and reset the MCB and powered up, after a short boot cycle it tripped and blew the fuse again (expected I suppose!). I tried removing the pumps from the PCB one at a time, it seems that when the boiler pump is connected it trips. Currently I have hot water and heating provided by the backup 'switch' elements. Noticed error code 24 but it's not in the manual. Could it be a seized pump drawing too much current causing it to trip, or it is more likely to be a PCB issue? With the rocker set to switch and the central heating and mains feed pumps connected everything else seems to work as normal. I haven't tested the pump manually to check if it's seized yet but I could do. Any other advice or suggestions from your experience?

Many thanks
Chris

Look like the pump

Have you removed the vent screw to see if free?

Removed cover and checked wiring inside pump.

Smell it too.

Thanks for the reply, it was the pump, it had seized.

Thanks again
