WATER WILL NOT DRAIN OUT ERROR 21 - Frigidaire GLTF2940ES Front Load Washer

E21 means a blockage in the drain pump.
I would check the impeller spins freely. A coin from a pocket can cause that error as it gets stuck in the impeller.

The Whirlpool washer error code F21 means the washing machine has a "water draining issue", meaning the drain pump itself, or the drain hose is clogged and the washer is having problems draining the water out

Can't remember the exact error code, but my crosley front loader would not spin. I found out this was because all the water was not being pumped out. I wash a lot of dog blankets and found out the drain basket was completely blocked. I was able to remove and clean from the back and this fixed my problem. I guess it could be the pump but check this basket first. The way I did it from the back was hard so I suspect there is a better way to access the basket.

An "F21" or "F02" error code is indicative of a slow draining cycle, normally caused by a clogged or kinked drain hose. If an "F21" or "F02" error code appears, check the drain hose on the back of your washer to ensure that it is not clogged or bent. Once the drain hose has been unblocked, the error code should disappear and the machine drain properly. However, if you have a high efficiency washing machine and the error code continues to appear, make sure you are using the correct detergent; because high efficiency machines use much less water than traditional washing machines, they require the use of a low sudsing detergent. Traditional detergents may produce too many suds, which can block the machine's drain hose and lead to slower draining cycles.

F21 on the tech sheet says Long Drain If the drain time exceeds 8 minutes the water valve turns off.
NOTE: After 4 mins the "Sd" error will be displayed then 4 mins later the f/21 error code will be displayed.
Press Stop two times to clear the display.

(Solutions:) Check drain hose
unplug washer and check electrical connections at pump
Check filter for foreign objects
If these fail it says to replace pump.

The error code F-21 refers to Long Drain. The washer has sensed that it has not drained out completely and cannot go into further cycle.

If yours is a HE 2 washer, afer few minutes, Sd error will be displayed and then after couple of minutes F21 error code will appear. Water valves will be turned off and stops running.

If yours is a HE front load, when drain time exceeds 8 min, F21 error will be displayed. The water valves will be shut off and pump will stop running.

Unplug the machine. Unscrew the 3 screws under the front edge of the washer. The service technician manual is attached to the panel that slides down and off. Find F21 code. See suggested procedures. Note: My drain pump filter had a baby wash cloth in it along with some change that was disrupting the flow. It is exceptionally easy to remove, clean, and reinstall. Just line up installation notches when reinstalling. Whirlpool should have mentioned this filter in the User & Care Guide, but I could not find it anywhere in there.
