HotPoint Dishwasher BFT68 - Error F75 or P45?

The dishwasher didn't complete a cycle after a series of elecronic sounds that came from inside the casing.
the flashing error was either F75 or P75 but I'm no sure as the LED display is faulty.
On opening the door there was still water inside that hadn't pumped away. Switched it all off and emptied the water out and checked there was nothing blocking the outlet. I then ran it on a rinse cycle but after 6 mins the error appear again.
Any ideas on what it is?
