The dishwasher hose is a corrugated pipe between the dishwasher and garbage disposal, so open it up and check. Make sure it is not damaged, kinked, or clogged.

if the dishwasher hose is bent, straighten it with your hand. If it’s damaged then replace it with a new Hose and if you find it clogged with debris then clean it by blowing.

To drain out the water, set the maximum speed and listen to a humming sound if the water is not draining out. A humming sound occurs if there is any problem with the pump.

The last thing to check before cleaning or replacing the pump is the impellers. Water may not drain out if something has stuck in the impellers.

Fix 7: Check Drain Valve

The drain valve uses an electric solenoid that opens the hole to pass out the water. If it gets stuck then it blocks the water to go out into the sewer. So check it and if you found any fault then replace it with a new one because no repair works on that.

PCB (Printed Circuit Board) controls the speed of the pump motor with the help of a sensor. So check the Printed Circuit Board and in case your PCB is damaged then use solder tracks to fix it or replace it with the new one. In case your processor is broken then replace the entire control unit.
