when this fault happens it normally floods the base of the machine and lift a float . this float is underneath where the motor and works are. if you tilt the machine backwards slowly !! I sress slowly as do it too quick and the water can get places it should not be. you need to give it time to leak out on the floor
once the water is out, try it again. If the fault repeats then you have a leak in a hose or similar and you have to find it
