Baumatic BKD60SS All the lights are flashing at once & beeping sound. ?

Turned my dishwasher on at bedtime & woke at 4.00am to a Beep,beep,beep....and all the lights flashing together. Opened the door & it was very hot inside. It sounds like it either isn't getting any water or it is trying to pump out. I have checked the water inlet & filter. I have unplugged it from the wall socket & left it for 15mins & retried, but it is still the same. The booklet is not at all helpful in the troubleshooting section and does not mention what flashing lights etc, could mean. HELP!
