Check to make sure the last wash cycle completed properly—if your dishwasher has a “Clean” indicator light, it should be illuminated. If not, the wash cycle may have been interrupted. Close the door and press the Start button.
Try running the garbage disposal (if you have one)—if it shares the same drain as the dishwasher, this can prevent the dishwasher from draining.
Check the drain hose that runs from the bottom of your dishwasher to the drain pipe (usually below the sink). Make sure it’s not pinched or kinked. If necessary, replace it with a new hose.
Remove the drain hose end from the nipple it’s connected to below the sink or disposal, put the end in a bucket, then fill and drain the dishwasher to see if a garbage clog will simply blow out. If that doesn’t work, but you see a small dribble of water, you may have to pull the dishwasher out and remove the drain hose in order clean it out or replace it. (Remember, there’s still water in the unit—so put a drain pan under it before removing the hose.)
If you recently installed a new garbage disposal, make sure the knock-out plug was removed. It’s right inside the nipple where the drain hose from the dishwasher attaches to the disposal. If it’s not removed, the dishwasher can’t drain properly.
The check valve is located underneath the dishwasher, just before the drain hose. It’s a one-way valve, allowing water to drain but not return to the dishwasher. Remove the drain hose from the dishwasher (remembering to put a drain pan underneath) and check to make sure the valve is clean and opens correctly.
If there are no obstructions to the drain system and your dishwasher is still filling with water, you may need to replace the pump.
Take the filter out of the bottom of the machine, usually done by twisting anticlockwise and lifting out. Clean thoroughly and put back, twisting clockwise to lock the filter back in place.
Underneath the filter is a removable plastic cover over the propeller. This can be pried out using a blunt knife and then lifted out. Check if the propeller moves freely and is clean of debris. Replace the clip and filter.
