If your dishwasher is not spraying water, the filter and pump could be clogged, the overfill float switch may have malfunctioned, or the spray arms are blocked. There may be water valve issues or inadequate pressure. You can check why it's not spraying water from the water supply valve.
It is quite common for a dishwasher to not drain because either the drain hose or the air gap (if the unit has one) is clogged up. Drain hose clogs commonly occur where the hose is attached to the main household drain line, or where the hose connects with the garbage disposer.
The easiest way to tell if your dishwasher is pumping water through all the spray arms is to take all of your spray arms and line them up at 6 and 12, so you're going to line them up, front to back.
If the inlet valve is clogged, the best thing to do is replace it, as attempting to clean it can make it more susceptible to failure. A new inlet valve for a Whirlpool dishwasher can range from $20 to $60.

Water in the bottom of the dishwasher results from clogs in the filter, garbage disposal, drain hose, drain pump, or air gap. When food or sediment build up within these systems, the dishwasher won't drain properly. Locating the blockage and clearing the debris will solve the problem.
A mixture of equal parts baking soda and vinegar poured into your dishwasher's basket and ran for 15 minutes, then followed up with a hot water rinse may loosen up clogs, according to Home Depot.

Standing water in a dishwasher is usually caused by pieces of food getting clogged in the drain. It's important to clean your machine's drain and dispose of any food debris. Before cleaning out the screen, remove the bottom sprayer arm, rinse it, and set it aside.
Dirty spray arms
By far the most common reason why your spray arms may not be spinning properly is the build-up of dirt and debris. Remove the dishwasher basket to freely access the spray arms and carefully clean them out. For more information on how to clean the spray arms, click here.
Spray arms are located at the bottom of the dishwasher and can easily be pulled out by a simple twist and lift. Spin the spray arm with your hand to see if it rotates freely. If it doesn't, it may be time to replace it.

Locate the solenoid valve, remove the inlet hose, and then unscrew the brass angle fitting. Loosen the inlet hose, and pull the hose away from the valve. Pop the screen out with a pick or small screwdriver, and clean or replace it. Reassemble the parts in the reverse order.
The check valve stops wastewater from re-entering your dishwasher through the drain hose. If the water in your dishwasher is draining, but then backs up once the drain pump turns off, you are most likely dealing with a faulty check valve.
The spray arms are usually powered by the water pump within the dishwasher. If the filter or the water pump is clogged, it will not provide enough pressure for the spray arm to spin as they should.
