I get error code e24 when operating the dishwasher normally. I have been able to get the dishwasher to run a full cycle using a suggestion in a post on this forum, however, I have not been able to diagnose exactly what is going on.
Following is a description of what is happening: The dishwasher is set to "Auto Wash", "Sanitize". When the dishwasher is turned on, the display indicates 2:41. A motor starts and runs for a short time, another motor starts and runs for a short time. The display goes to 2:40 and a motor starts and runs for a short time. The display goes to 2:39 and "e24" is displayed.

I am able to make the dishwasher run normally by opening and closing the door a short time after the display changes to 2:40.

I have replaced the float switch, the control board, and cleaned the drain pump and hose. The results are the same as above.

I also ran the test program. The program stops at step 6 and displays e24.

I am stumped as to exactly what is wrong.
