1. Check for a clog in the air gap:
That's the silver dome on the back of the sink. Not all homes have an air gap for the dishwasher. (Though it is highly recommended!) Lift off the silver cover. Unscrew or unclip the plastic cap on the top. Look inside. Toothpicks are often found there.

2. Check for debris in the sump by:
Remove the lower rack, the lower spray arm, and screens. Use a #15 Torx bit to remove the cover over the drain pump suction. The hole leading to the drain pump is on the left at the bottom. Remove any debris you find.

3. If you find no debris, you almost certainly need a drain pump. After clearing any clogs, if you hear the drain pump humming, but it doesn't turn, replace the pump.
Comment back if you directions for this.

Good luck!

Hi

Kindly check for the following :

Check for hose kinks or food plugging drain hose. Start at the drain port exit.
Check the check valve and drain hose for debris.
Check pump motor for reversing during the pump out make sure the dishwasher is pausing between the wash and drain cycles letting the pump/motor reverse for the drain cycle.
Check pump motor assembly for a drain solenoid, during the pump out make sure the solenoid makes that distinctive "clunk" noise
If you have recently installed a new garbage disposal, check knock-out plug at connection.



Check pump impeller for damage.
Check that the water inlet valve isn't seeping fresh water into the dishwasher when off.

Please contact for any further clarifications.

A Fixya Rating would be appreciated if.

Thanks

You can check the drain or the filter. You will have to pull it out of the space it is now to access it. Items will get stuck in the drain clogging it.

I ran into the SAME problem with my Bosch SHX46A06UC /21. The problem ultimately ended up being a clog in the air gap vent, (meaning, SOMEBODY ran the dishwasher without the bottom filter being in place or not in place properly). Remove the air gap cover and upper surface nut to drop the air gap vent into the area under the sink. Disconnect the hoses from the air gap vent filter (placing a bucket under the hose from the dishwasher). Run the drain cycle on the dishwasher. The washer should drain into the bucket and let you know that your pump works and that there are no clogs or kinks in the drain hose. (This will also remove the clog if so). The air gap vent's smaller hose connection is MOST LIKELY where your clog is. Look at the upper end of the air gap vent. You'll see a couple of clips on opposite sides of each other, that hold the air vent cap in place. Using a small screwdriver, (or your hands if you can), depress the clips (or one at a time) to get to the point where you can pull the vent cap off the filter. Either use water or a thin, long blade screwdriver to force any objects out of the filter. You should now have full flow through both branches of the filter. Using water and a rag, clean the vent cap and filter. Mount the air gap vent filter back onto the sink. Reconnect the hoses and remove the dishwasher's internal filter(s) and clean them as well while you're at it, making sure to remove any debris that might remain underneath the filter and has the chance of clogging the unit again.

Run the washer again to test. You should be good!

Cheers!
