Think this must be the PCB as its totaly dead and cant see anything obvious.
It’s made by Hoover Candy group but is unbranded and has the model HJA8703 on it.

The PCB is located at the back L/H side. It’s quite a large module with the riband cable running up past the mains suppressor all the way to the front where the push button switches are.
It has a small ‘clip in’ selector with a microswitch that switches the machine on when it passes the off position.
All wiring checks out and continuity through the selector microswitch when activated so think it must be the main power board.
