E21 error code

Hello
You try this it may help.
How do I fix error code E21 dishwasher?") Circulation Pump Blocked

1. Remove any excess water before removing the base of the machine to release the pump.
2. Check and remove any blockages preventing the circulation pump from turning and Replace if any damage is found.

Hello Deena,
Error Code e21 means the water is not pumping out fast enough.The most likely reason is because the washer drain filter is clogged.
Here is a solution:

1. Pull the machine out from the wall.
2. Then take the panel out in the rear. Once the panel is off you will see the drain pump.
3. Disconnect the drain Tube between the Tub and the Pump.
4. Look inside the pipe you will find the Drain Filter.
5. Clean the filter out ( you will be surprised of "things" found in the filter) then put the machine back together
6. Try a full cycle.

That should end your problem.
Best of Luck!

The E20 error code is a class code that indicates a drain problem in the washer. This is consistent with the drain and spin problem that you are observing. To determine the exact error code, follow these steps:

Wake the machine by pressing any button

Wait 5 seconds

Press and hold the START and PAUSE/CANCEL buttons simultaneously

The exact error code (E21, E23 or E24) will be displayed.

If E23 or E24 are displayed, you will normally need to replace the control board due to a failed drain pump relay.

If the E21 code is displayed, I recommend that you follow these troubleshooting tips:

Check the washer drain to see if it is clogged.

Check the washer drain hose for a clog or restriction.

Make sure that the washer drain system complies with the installation instructions for the washer.

Try to gravity drain the washer by placing the drain hose in a bucket on the floor. If the washer will gravity drain, you may be able to

unplug the washer

and remove the bottom front service panel using the procedure in the image below. Arrange towels to catch residual water that may be in the washer and check the pump filter and drain trap for a clog or debris. If you find no clog or debris, then you may need to replace the drain pump. NOTE: You should not attempt this procedure unless you are completely confident in your technical ability to safely access and check the pump. Do not disassemble the drain pump hose if the washer is full of water.

It is the customer fault code. Simply turn on and turn off appliance.
E11 - problem with fill water
E21 - problem with draining water
E41 - door open
All other errors require service staff !!!

Hello debbiecantu1 - Typically error code E21 indicates an issue with the water not pumping out fast enough. Does the unit make a humming noise? If so, either the drainage hose/pump is clogged and needs to be cleaned. Try setting the cycle to spin only and verify if water pumps out. If it does not, then the unit could possibly be experiencing an issue with a faulty pump, timer, door lock assembly or control board. Contact a professional to move forward accurately.

If the control detects that the washer still has water in it even though it is apparently dry, the control will continue to run the drain pump and will not go into the spin model. If the tub is completely dry, you could have a problem with the water level pressure switch or the control board. This would normally cause an E21 error code on the washer. I provided the technical information for this washer in the image below. The washer will normally signal an error code with a series of blinking lights on the console when the washer will not go into the spin mode. I recommend that you continue to allow the drain pump to run for a while and see if an error code will appear. This will normally indicate the likely failed component that is causing this problem. The information below is intended for technicians. Follow electrical safety guidelines if you use this information. Unplug the washer to disconnect electrical power before accessing internal components. Some of the checks below call for live voltage checks. I do not recommend that you conduct this type of test on the washer. Live voltage checks should only be conducted by a service technician.

Hi, water not draining fast enough. Try holding the start/pause and cancel key together for 3 seconds. The door lock, wash, rinse and final spin leds should light. Any error codes should be displayed when holding those keys. If you see a different error code, post it. If not, I would suspect a clogged pump.
Drop the bottom front panel. The pump sits on the right side. Disconnect the drain hoses and clean them and the pump impeller out.

check drain pump for obstruction, (access from rear panel) pull hose boot from tub and ck basket in hose. read tech sheet for code definition while your there. have plenty of towels and wet vac ready

E21 Water not pumping out fast enough. .
Check for Restriction in drain pump or hose...
No restriction. Go to step (2).

2. Start the washer and check for 120 VAC at the
drain pump. if no voltage Replace the control board.
120 VAC. Remove the pump and check for
blockage. If blocked, remove the restriction,
if not, replace the pump.

E21 is telling you that it has not drained the water out. You may have something stuck in your drain pump.
