how to repair the VAX 121 wet & dry?

Hi
I recently had to use the VAX 121 to take up water, in my haste the lid/motor was not lined up/fastened properly so a little water ended up in the motor (as the tank was overflowing) which then shorted out. I left the motor to dry out by a radiator for some time, but still when I switch on, it still shorts out fusing the other electrics on the kitchen ring!...is it beyond repair??
