What Does F21 Means In Your Whirlpool Washer?

Your whirlpool washer gives you error code F21, and you don’t know how to fix it. In this paragraph, we’ll inform you what does F21 means in a whirlpool washer, its causes, and its solution. 


#1. Reset the washer 

To terminate the ongoing wash cycle, whenever the “F21” error code occurs, hit “Cancel or pause.” If there is still water inside the washing machine bucket, press “spin or drain” to initiate a second drainage cycle. After all the water has drained, pick a new washing process and press the “Start button.”


#2. Drainage hose

If you noticed error code b”F21″ again after resetting the washing machine, t means there is an issue also with the drainage pipe. For this purpose, remove the drain line from either the back of the washer, then place clothes on the bottom floor to cover any water leaks. Wipe the hose’s inlet and spin it vigorously to eliminate any obstructions. Level the drain hose before reconnecting it to the washer since twists in the connection might produce a drain problem. Read about how to clean washer drain hoses and how to install washer drain hose.


#3. Drainpipe or standpipe facility 

The drain hose must be correctly installed into the standpipe facility for good drain efficiency. Therefore, problems in the hose or the drain facility can also cause the F21. Measure the length from the base of the washing machine upper part of the drain hose,  at the area standpipe is linked to the drain hose.  If the gap between the base of the top load washing machine and the top of the drain hose is more than 96 inches, then detach the drain hose and tie it to the standpipe for a secure connection. If the drain hose is put too deep into a drain hole, take that out gently to provide an air space between the drain and the hose. If you need help with any of these tasks, call a plumber.


#4. HE detergents only

Do you know that the Whirlpool Duet washer is a powerful machine that needs the use of high quality and good efficiency detergent with the letters “HE” just on the label? Different kinds of detergent might generate excessive foaming during the wash cycle, which causes drainage to be slowed or stopped, resulting in the “F21”   code error. Remove the surplus water and soap from the machine to fix such issues and choose a fresh “Drain or Spin” cycle.  You have to follow the directions that are mentioned on the item bottle for the right amount of use, or fill a little to the “Fill” line within the dispenser when you are using HE detergent only. By using a HE detergent, the  F21 never occurs. 


#5. Services

A power reset may be required if the code error “F21” remains following resolving procedures with the drain hose, drain facility or standpipe, and detergent.  Just Wait 30 seconds after turning off the Duet Whirlpool washer. Reconnect the power supply to the washer and start a new and fresh washing cycle. If the “F21” problem still appears when power is supplied, and then it’s better to contact Whirlpool for help.


#6. Damaged control board

A malfunction in the mainboard might also generate a Whirlpool washer F21 code. When there is no signaling to start the drain cycle, this might happen. It indicates that draining times are more remarkable than usual, resulting in an F21 fault signal flashing. Fault currents and de-soldered cables can cause significant damage to the control board. Whether this happens, you’ll need to repair the burnt board (it will cost between $150 and $500). If not, soldering should be able to fix it.

#7. Sever pipe blockage

A malfunction in the control board might also generate a Whirlpool washer code error F21. You may have a sewage obstruction if water is flowing out of the washer yet pouring out the drain tube. Coins, rubbers, socks, and paper may block such plumbing lines. In this scenario, remove the pump and clear any material from the pipe. If the adapter clearance becomes too thin due to debris or dust from the far water, it must be replaced. Here are the ways to clear a clogged waste pipe.
