    Mine did the same thing, but it's a Frigidaire model FDBB2040FS0. I don't see any breakers thrown in my circuit breaker box, so I'm guessing there's a breaker somewhere in the dishwasher that got thrown *or* the dishwasher was going into "burn, baby, burn" mode & melted through some wiring instead. I'm searching the web for info. on a reset button. If I can't find any info, I may just pull the dishwasher out & look for one around the outside. Good luck with yours.

Our Whirlpool dishwasher model WDT720PADM1 stops in the middle of cycles or won't start the cycle after water has been pumped in.

All of the things that you are describing are controlled by transistor circuits, and relays, and solenoids. The next time it fails would be the time to call a service repairman with the test equipment and training to locate the failing circuit card or component and replace it. The ticking sound could be a bad relay chattering or a defective solenoid opening and closing. There is no way to diagnose the problem remotely. Even if there were it would require special training to locate and replace the part. Hope that is helpful.

Dishwasher took 3 hours to complete cycle

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.
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
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?

My dishwasher was in the middle of a cycle and it just quit. The buttons dont light up. It doesn't turn on at all. What could be wrong with it?

Sonya, have you checked the circuit breaker in your home's circuit breaker panel to see it has been tripped? Also, is the dishwasher door tightly shut? If the breaker is tripped, reset it to see if the dishwasher trips it again. If it does, either breaker is faulty or the dishwasher has a short circuit in the electrical circuitry. You'll need an authorized service person for that.

No power or lights in the front panel

Check the fuse / circuit breaker inside washing machine. There may be a extra control circuit fuse normally on the control PCB.

My Kenmore portable dishwasher quit working in the middle of the wash cycle. It has power going in, but no longer runs at all. I need a service manual or a troubleshooting guide. Is there a circuit breaker...

This seems to be that the Anti Flood system has triggered. This device detects water leaks / spills to the bottom of the washer and automatically puts the washer in pump out mode and shuts off the water inlet. The device is made up of a pollystireene float and micro switch that activates once the float detects any leaks / spillage. Dry water and check for leaks and this should solve the problem

Suddenly stopped working - won't run on any cycle.

First check the electrical supply. I have seen dozens of dishwashers which did not have the hot wire connected tightly enough (inside the connection box behind the lower panel). Sometimes the loose wire caused the breaker to blow. If you have control lights but the dishwasher will not start it could be a bad door latch saftey switch. $10 part, cheap. Hope this helps, Ken
