I shut off the water supply and use the dishwasher to pump out all the water before opening the door. I removed the bottom access panels and checked that the float was not stuck. It moved freely. I made sure the dishwasher was off and turned the water back on. Water was flowing into the dishwasher even though it was off. This told me the water inlet valve was not shutting off. I purchished a new water inlet valves and followed the instructions on the video for installation. It worked perfectly. The new inlet valves arrived on the second working day.
