Hi All
Recently purchased a flat and i know the boiler has not been used for months as the place was unoccupied.
It does power up for a few second then BOTH fuses blow on the PCB, the display shows '7' when the power is on.
Could this be something simple like a stuck CH pump (Grundfoss) or fan ??
The PCB is visually ok (no burn marks/tracking etc)
I also have access to another F24B which is in full working order in the flat above if i need to swap parts to fault find.
Bot were fitted at same time an in good condition, its just the non working has been laying dormant for months..
F1 and F2 quick blow fuses are blowing - 3.125a. In the pic below on top rhs of pcb.

Where can i start testing ? Uplug te pump ?? Remove the pump ??
Cheers
