Hello, my name is***** am a plumbing contractor. Dishwashers use a pump to drain the water out of the bottom of the dishwasher. It sounds quite possible that the pump is not working.
The drain pump uses an impeller to force water through the drain hose. If the drain pump motor is not working, the dishwasher won’t drain. To determine if the drain pump is defective, check the pump motor for continuity using a multimeter. If the motor does not have continuity, or if is getting power but won’t run, replace the drain pump. Drain pumps are not repairable—if the drain pump is defective, you must replace it.
Okay thanks. They have gotten a lot quitter.
