Here is a video from Bosch that shows you step-by-step what to do if your dishwasher does not drain.
Here is a common problem I have run into a number of times in the last few months. This Maytag MDB7100AWB dishwasher was dead, just as if it was unplugged.
Sometimes I see this type of dishwasher where the lights on the control panel may work, but you can’t start the dishwasher and other times I have seen were no lights work, but you can start the dishwasher.
In all the above cases I ended up having to replace the control board, part # 99002824 to repair the dishwasher.

Soil sensing is performed in all wash cycles except the Rinse only cycle. Mounted on the right side of the sump, the soil sensor transmits light from a transmitter to a receiver to measure the amount of soil in the water. This information will be used by the control to determine the length of the cycle.
Once pre-wash loosens food on the dishes, the motor stops for 30 seconds. This allows the wash water and food soils to settle for the soil sensor to check the soil levels in the water.
Now that this reading is taken, the dishwasher drains the dirty water and fills again for the pre-wash rinse. Once this rinse is complete, the wash motor pauses again, a soil level measurement is again taken. The control uses these readings to adjust the wash cycle to ensure a clean load of dishes.
In this video I show you how to remove the food chopper in a whirlpool dishwasher so it can be cleaned or replaced. If the top arm of your dishwasher is not rotating around it could be because the food chopper screen is plugged restricting the amount of water going through the pump. If this happens sometimes you can simply clean the food chopper screen, but most of the time it’s best to replace the food chopper because the blade has been damaged.
Often times I find a noisy dishwasher also has something stuck in the food chopper. In this case simply removing the food chopper and cleaning it takes care of the noise.
This video show you how to test a dishwasher heating element with a multimeter.
Testing and replacing a bad heating element in a dishwasher is a simple repair job that any one can do.
Simply set your multimeter to ohms and check the element for continuity. If you have continuity across the element then it is good. If you do not have continuity across the heating element then it is bad and it will need to be replaced.
If you have a bad dishwasher heating element you may notice the cycles take longer to finish and the dishwasher does not get things clean like it use to.

Have you noticed a white film or residue on their dishes, glassware, plastic items, utensils and tub interior?
The problem is likely not the dishwasher’s cleaning performance, but may be hard water or phosphate-free detergents.
As of July 1, 2010 seventeen States* passed laws limiting the amount of phosphorous (phosphates) in household dishwasher detergents to no more than 0.5 percent. Previous detergents contained up to 8.7 percent. As a result, major manufacturers have reformulated their dishwasher cleaning products.
*States include Illinois, Indiana, Maryland, Massachusetts, Michigan, Minnesota, Montana, New Hampshire, New York, Ohio, Oregon, Pennsylvania, Utah, Vermont, Virginia, Washington and Wisconsin.
WHAT ARE PHOSPHATES?
Phosphates are mineral additives in detergents that act as the main cleaning agent helping remove stains, break down grease and reduce spotting.
During washing, phosphates suspend food particles so they don’t stick to dishes. Plus, they soften water allowing suds to form for cleaning.
DID YOU KNOW:
Phosphates have been limited in laundry detergents since 1994. The change in dishwasher detergents is another step in the eco-conscious awareness found in today’s products and the eco-friendly choices consumers are making.
