SOURCE: Not enough water
Be aware that you should remove dishwasher's power cable before touching wires or making resistance measuring !!! Check that the inlet valve get power. In case it does and no water entering the tub, check with multi-meter for solenoid's resistance (disconnect first the wires to it),if no measurement result, you should replace the valve. In case you have a measurement result, remove the solenoid from the valve and check that it's clean from any dirt. In case there is no power to the inlet valve - check that the float switch works. This is usually a small switch attached to a float. The float (usually a cylindrical) located inside the dishwasher at the bottom. As the water level rises, the float rises too. When it reaches the certain height, the float activates its switch, which cuts the electricity to the water inlet valve. If the switch is defective (stuck in the disconnected position)it will prevent power from the inlet valve. The switch is an On/Off switch and you can check it easily by a multi-metr. Good luck !!

SOURCE: Dishwasher drains continuously
I dismantled and checked various parts of the dishwasher and everything seemed to be working. I noticed with a phase tester that the pressostat never got any voltage. This led me to check the microswitch on the door which turned out to be broken (never making any connection). This is the microswitch that turns off the dishwasher when someone opens the door.
So an unusual problem - two faults at the same time i.e. clogged and overflowing drain and broken door switch!
I ordered and fitted a new door switch and now the machine is working fine again.

SOURCE: Maytag MDB6650AWW will not fill
My Maytag MDB6650AWW dishwasher would not fill. The lights on the panel were on when I tried the wash cycle. I tested the water valve but no voltage was found during the cycle. I thought it may be the timer/control circuit. I traced the power from the door switch and found no power going to the float switch leg. I found two wires completely cut through (one going to the Water Valve) and three others partially sliced.

my repairman contacted whirlpool about my washing machine staying on
wash.. to his surprise.. and mine.. and his co=workers.. this is the answer,
it worked.. and we have never heard this before.
In your original istallation booklet it tells you to let the dishwasher run til its complete
the first time you use it as it may rinse twice... my original installation man told me this also.
however.. if you suffer a "blip" in your electricity.. it could put the little dishwasher "brain"
out of whack.. it can run as long as 3 to 4 hours on wash to reset itself.. if you stop it
(like others have mentioned.. and which I did also).. it doesn't complete the reset and it
will attempt to do it the next time..
answer?.. just let it go once as unnerving as this is.. it works.. They did mention that
if it went to 5 hours.. call your repairman because you need a new mechanism.

There are actually several possible causes of your problem. I will briefly describe each in hopes that you can isolate the problem and will then know how to proceed.
If the water doesn't drain from your dishwasher, check these:
Drain line/air gap
Drain valve and/or solenoid
Drain line/air gap A clog in the drain line or air gap (if there is one) is the usual reason that a dishwasher won't drain. Often the problem is at the point where the drain line attaches to the garbage disposer or household drain line. If you remove this line, you can clear any debris from the hose or hose connection. Be sure to reattach the hose before starting the dishwasher again.
Pump Your dishwasher pump ejects the water. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher. You can reach the pump from inside the dishwasher, but first you need to remove the lower rack, the spray arm, and the spray arm support.
Look for an impeller--a round plastic fan blade-type of device that spins around. This is the wash impeller, which forces the water through the spray arm. Beneath the wash impeller is the drain impeller, which is similar in size and shape to the wash impeller. The drain impeller pushes the water toward the drain port. These components make up the pump. If any of the pump components are defective, you need to replace them.
Drain valve and/or solenoid Many dishwashers use a drain valve with an electric solenoid. When electricity flows to the solenoid, the valve opens and diverts the water to the drain. Sometimes the solenoid, or the diverting lever, sticks and prevents the dishwasher from draining or filling properly. Try to free up the solenoid to lubricate the lever. Otherwise, you may have to replace the solenoid or pump assembly. With these systems, the motor always rotates in one direction. When it's energized, the drain valve diverts the water.
Other dishwashers simply reverse the direction of the motor to drain the dishwasher. These units don't have a drain valve. Instead, there's a drain hose connected directly to the pump housing.
Belt One brand of dishwasher uses a belt to drive the pump. If this belt is broken or has fallen off, replace it.
Motor If the motor isn't turning or working, the unit won't drain. First check to be sure you have power to the dishwasher. If not, see the section "It doesn't work at all." If the motor hums but doesn't turn, it may need to be replaced.
Some dishwashers are susceptible to getting stuck if you don't run them regularly. If you haven't run the dishwasher for more than a week, you may need to manually spin the motor to free it up. If the motor is defective, you need to replace it. Dishwasher motors can't be serviced.
Timer Part of what the timer does is control the motor and drain valve. If the timer doesn't work properly, the water may not drain and you need to replace the timer. This problem is uncommon.
