SOURCE: drain pump and no water going in
This most likely is not a level switch problem. Take the kick plate off (after turning circuit breaker OFF), look down in the base off the dw and youll probably see some water. Use a wet vac or towel to remove all water. The drain pump will now shut off and unit should function normally. You can now run the dw with the kick plate off and using a flashlight look for leaks. The bosch dw has a float switch in the base, water will activate this switch which will shut off the water valve and only allow the drain pump to run....it thinks it has a leak!
Make sure the disposal is draining properly & drain hose is not kinked as these are the most common reasons for your problem.

SOURCE: drain pump won't stop
that usually happens when there is water in the base of the dishwasher where the motors are. Check to see if there is water in the base. This will trigger a float that turns off the water and on the drain pump.Remove the water and it should fill. However note that water came from somewhere, so find where it is leaking.

sounds to me that you may have some suds residue in the dishwasher that keeps it from draining completely. Get you some dishwasher cleaner which you can purchase at wal-mart or wherever you buy your detergent, and clean out your dishwasher. It is a inexpensive test. Alot less expensive than having a tech come to your house. Make sure that your drain hose is mounted higher that where it goes into the drain. This is also a common problem that I encounter in the field. Hope this helps. Let me know if I can help you futher.

If the cycle does not stop draining that is usually because of a faulty
water level switch that controls the water level in your appliance.
The faulty sensor cause the machine to think that there is still water inside, even when water has drained completely.
Check if the floating sensor is stuck or faulty.
Some machine may use a membrane switch instead of a floater.

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.
