hotpoint aquarius sdl 510 error lights

Hey

I have a hotpoint sdl 510 dishwasher,when I start a cycle the machine will prepare itself but then will stop and the 3h/wash, 6h/dry and 9h/end lights all flash rapidly, the drain pump also spins, it will stay in this state unless I push the power button.

Any help would be great as I cannot find any information regarding this machines error codes online at all.

Many thanks
