Water will not drain from my dishwasher.

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. Try removing the drain hose to unclog any debris. Don't forget to reattach the hose before you start your dishwasher again.

The pump assembly is comprised of a pump, wash impeller, and drain impeller. The pump ejects the water from the unit, the wash impeller pushes water through the spray arm, and the drain impeller directs the water towards the drain port. Examine your dishwasher's pump assembly. Clean out any debris that may be blocking it. Replace the pump assembly if any of its parts appear to be worn or defective.

It isn't very common, but sometimes a dishwasher's pump assembly is driven by a belt. If that belt becomes worn and defective, then it cannot properly run the pump that drains your dishwasher's tub. If your dishwasher uses a drive belt, examine it now. If it shows signs of wear, replace it.

The motor plays a key role in a dishwasher's ability to drain water. If your dishwasher's motor is not functioning properly, it will negatively affect the draining capability of your machine. Test your dishwasher's motor for continuity. If it fails the test, replace the motor.

In some models, a valve has to open in order for the water to drain out of the dishwasher. This valve is controlled by a solenoid, but it is the timer that decides when the valve should open. If your timer is working fine, check the drain valve and its solenoid. If need be, replace them.
