My Kitchenaid Custom 21 dishwasher does not drain. It seems like it is the drainange hose, how do I unclog it?

Float valve is jammed.

Look inside the machine on the floor will be a small float valve. Looks like a small upside down cup. Lift it and clear anything from underneath.

The valve is a safety feature to stop the machine from over filling. If anything gets under the valve it will jam open and stop the machine.

Not working?

Check for a clog internal or external.

Scoop as much water our as you can. Open the cover on the floor of the machine. Usually just turns and lifts out or snaps out some are screwed in. Take your time and try not to force anything. Look for a clog there.

Check for clog in the drain. The dishwasher will connect to the drain under your sink and run either directly to the drain or into your disposal unit. Remove open the connections and look for a clog. Clear if necessary.

Not the clog?

Water is pumped out by the machine via an internal pump located under the base. If it fails the water will collect until it trips the float valve. First scoop out all the water from the machine and run it again. If water comes in and it runs to the point it fills again and trips the float then either the pump or timer is faulty.

Pump check.

Remove the machine. It will be held in place by screws directly into the counter top. You may have to lower it to get it out. The front feet turn with a wrench to lower.

Turn off the water supply. Run the unit again until you get to the drain cycle.

Connect a test light or voltage tester to the terminals at the pump. Check for voltage at the pump. If you have voltage replace the pump. If no voltage the timer is faulty.

Timer problem?
Some can be replaced as a unit others are integral to the control panel. Turn style can be replaced. Touch control can not.

Hi, this is a control fault that is localized in the logic sector of the control board. the logic chip which holds all wash programing is damaged. you will need to replace the control asap if possible...
