Motor does not stop running

I couldn’t find any error code 2H but I did find an error code H2O. This code means insufficient water pressure. If the display reads 2H, it usually means the start delay function is turned on. The dishwasher will turn on in 2 hours if door is closed. This dishwasher is advanced. To understand all operations you should read the user guide or manual.

If you have set the unit to heated water or your hot water is not hot will delay the wash cycle. The heater in the dishwasher is very slow!
The following is from the user manual.

TROUBLESHOOTING
First try the solutions suggested here and possibly avoid
the cost of a service call...
Dishwasher is not operating properly
Dishwasher does not run or stops during a cycle
Is the door closed tightly and latched?
Is the right cycle selected? Refer to the "Cycle Selection
Charts."
Is there power to the dishwasher? Has a household fuse
blown or circuit breaker tripped?
Has the motor stopped due to an overload? The motor
automatically resets itself within a few minutes. If it does not
restart, call for service.
Is the water shut-off valve (if installed) turned on?
Dishwasher will not fill
Is the overfill protection float able to move up and down
freely? Press down to release.
Dishwasher seems to run too long
Is the water supplied to the dishwasher hot enough? The
dishwasher runs longer while heating water. Refer to the
"Dishwasher Efficiency Tips" section.
A delay automatically occurs in some wash and rinse cycles
until the water reaches the proper temperatur

Hope this helps?

The unit normally has a 1:20 to 1:30 fill cycle with pauses in between while the wash motor starts and stops without running a diagnostic mode this normally happens when the control outputs power to the wash pump motor but the pump doesn't start

Hey Bill,
Not professing to be any kind of a dishwasher repairman but I have had a similar issue with the start and stop thing and it turned out to be the timer motor had started to go, and in going it 'burned' a couple of sets of the contacts as well. Check with a local appliance repair centre and see first if they agree with me, and if they have anyone who can rebuild the timer - Typically not too hard to get access to and remove - In my case in Canada, it had to go to Toronto pre-paid but $70 was cheaper then a new dishwasher and it's worked great for years

Hi,
That sounds like a sensor and/or control board issue...

The board has gone wacky and is not running the cycles correctly.

First thing I would do is to get a new board in there and see what happens..

THE MOTOR SHOULD MAKE NOISE IF ON, CHECK THE MOTOR OR TIMER.

If you hear a hum when it should be washing, the motor has seized. Replace motor. If it fills with water and stops quite, run it through a test using the tech sheet under the bottom panel to access. These dishwasher have had issues with the motor.

I have a Bosch Dishwasher, SHU6805UC/U06, During a cycle it was interrupted by opening the door. It was left open for an hour. When the door was closed again the lights came on but the cycle did not continue. The motor did run but no water was rushing. Power interrupted to the machine did not enable it to reset or restart. How do we get it going again?

Just on a whim i would say the bearings in the motor are worn.Any leaks?It's also possible that some broken glass went through the screen and into the pump motor if any glass has been broken.

Sounds like you have a one of four possible issues. More info to diagnose would be helpful. (age, which mid cycle) If the motor runs when you turn the timer dial than it is a belt/motor pump issue. If the motor does not run than a bad motor start switch or the water level switch. More than likely the motor/pump assembly as this is usually the problem on these models. If newer check with whirlpool the manufacturer to see if it is covered by warranty.
