F21 on a Whirlpool washer means what? To put it another way, it means that the Whirlpool washer is unable to adequately drain water. The drain line and drain pump can become clogged with debris and grime, resulting in stagnant water.
After a while, the washing machine’s ability to remove water is lost.. Draining the tub will take much longer if this mistake occurs.
A kinked or clogged drain hose is another typical issue, as is not using high-efficiency (HE) detergent. However, if the problem continues to appear, you should seek the assistance of a specialist. Let them take a closer look at the other conditions that have been outlined in this section. Knowing where to get washer lid switches could be useful.
Reset Its Error Code
When you encounter the F21 error, try pressing Pause or Cancel to halt the current wash cycle. Next, if water is still in the tub, hit the drain/spin button. As a result, the drain’s secondary operation must now remove the tub’s water. Washing begins anew after you watch the water flow away. To begin the repair process, simply click the “Start” button.
Clean The Washer Drain Hose
If the F21 error persists, the problem may be with the drain pipe. Place a towel on the floor to keep it dry in the event of a water leak. Disconnect the drain hose at the back. Drain hose access should be sanitized. Remove the hose and shake it with your hand to dislodge and remove any clogs that may have formed.
Straighten the drain hose before reconnecting. Drain difficulties are caused by any twist or bend in the hose. Consider learning how to clean the drain hoses of your washing machine.
Check Drain Facility or Standpipe
Drain hoses should be inserted into the standpipes or drain facilities correctly. Drainage will take place as expected. The F21 error code is a result of drain or standpipe issues. Troubleshooting instructions are provided below.
#1. Drain hose connected to the standpipe
The distance from the drain pipe to the whirlpool washer should be measured. If the distance is greater than 96 inches, remove the drain hose and store it at the base of the standpipe. And make sure it’s secure.
#2. Drain hose inserted into the standpipe
If you’ve pushed the drain hose too far into the standpipe, simply pull it upwards. Prevent clogging by leaving a space between the drain and the drain hose. When it happens, the error will be fixed.
Use The Right Detergent
Whirlpool’s washing machine is a power saver. A high-efficiency detergent is also required. If you don’t use a HE detergent, you’ll end up with a lot of foam in your washer. The drain tube is now clogged with foam, resulting in the F21 error code.
Resolve the problem by switching to a new spin or drying cycle that eliminates any remaining soap or foam. However, when washing, be sure to follow the directions carefully and only use the recommended amount of detergent.
Check The Faulty Motor
Motor failure is to blame for the F21. While the drain cycle is starting, make sure the drain pump has enough power. Ensure that the drain pump receives 120 volts when it is running
It’s possible that the supply control board isn’t sending enough power to the drain pump to get it up and running properly.
Allow the drain pump to get the proper power. After then, troubleshoot the pump to find the problem. Next, disassemble the pump to check for any obstructions. For mechanical or electrical issues, a multimeter can be an invaluable tool. Drain pump replacement is finally completed.

8 Causes And Solutions Of Whirlpool Washer F21 Error Code
To help you fix the F21 error on your own, below are some possible causes and how to fix them.
It’s possible to implement some of these solutions in a reasonably short period of time (and free or inexpensive to fix). It’s unfortunate that some people are not!
#1 Clogged Drain Hose
The drain system is implicated in the F21 error code, although there are a number of other factors at play.
It’s possible for buttons, coins, and other items that come off clothing or are left in pockets to clog the drain pipe. It’s also possible that it’s wavy.
- Remove the washing machine’s power plug from the outlet to turn it off.
- In order to reach the washer’s back, it is necessary to move it away from the wall.
- Check the washer hose for kinks, bends, and clogs by disconnecting it.
- Water or air might be used in order to check for any obstructions.
- If water won’t flow, use a long-handled hook to push the blockage through.
- Ensure that the cable is not kinked or bent before reconnecting it to the machine.
When relocating the equipment, take care not to pull on the sewer connection by accident. Doing so will cost between $19 and $35 to replace the entire drain hose.
#2 Dirty Filter
By removing the front bottom panel, you can access the pump, mesh hair catcher, and wiring.
First, remove the screws holding it in place.
Brush the crud out of the filter. Use running water to rinse and replace.
#3 Clogged Pump
A F21 Whirlpool washer error message may be displayed if the pump itself is clogged or the corrugated tube that connects the pump is blocked.
The pump is located at the bottom of the washer, behind the front bar:
- Unplug the machine from the wall to disconnect it from the network.
- Removing the bottom panel is as simple as unscrewing the screws and lifting it out of place.
- It’s a good idea to lay down towels or a container at this point to catch any leaks.
- Remove the drain filter from the washer.
- Remove any foreign objects that may be causing the obstruction.
- Make sure the washing machine filter and other parts are clean.
- Restore order to the situation.
- Reconnect the machine to see if it now works.
You’ll need to replace the pump if the old one has failed. You may expect to pay anywhere from $30 to $160 for a model and store.
#4 Damaged Cable Loop
It is not acceptable for a cable loop to have any loose contacts or breakage. To ensure that the plug is firmly seated in the groove, you can either twist or solder the ends if you notice an issue.
The machine won’t be able to pump water if there’s a problem like this. The F21 error code is generated as a result of this.
Use a multimeter (multitester) to check each wire individually if there is no evident damage.
#5 Broken Pump Motor
It is possible that the pump motor has failed if you are certain that the wires are not damaged and the drain hose and filter are not clogged.
A multimeter can be used to check. To work effectively, the pump requires a voltage of precisely 120 volts, not more or less.
Lower readings mean you’ll need to replace the pump, which can be found underneath and hidden behind the machine’s front panel.
#6 Defective Pressure Switch
The drain pump is connected to the main control board through a pressure switch. It is possible to get an F21 error code if there is an issue with this connection.
In the event that the pressure switch needs to be replaced or repaired, use a multimeter to do so. Getting to this pressure switch isn’t a big deal:
- Disconnect the machine from the wall outlet and turn it off.
- Remove the top cover.
- Remove the bar by undoing the three screws holding the back panel in place.
It is located on the right side of the washer, to the right of the detergent dispenser. A rubber tube connects the little disk to the hose.
The cost of a new one is going to be roughly $70.
#7 Defective Control Board
The control board of a Whirlpool washer might potentially malfunction, resulting in an F21 error code.
This can happen if the drain cycle is not started because there is no signal. Drainage times are taking longer than usual, which is why the F21 fault code is blinking.
The control board can be severely damaged by de-soldered wires and short circuits.
Replacement of the burned board will cost between $200 and $450, depending on the severity of the damage.
A simple soldering job could solve the problem.
#8 Sewer Blockage
If the machine is pumping water out, but the drain tube is leaking, you may have a sewer clog.
Coins, socks, and scraps of paper can clog these pipes.
Remove the nozzle from the pipe, and then clean the pipe of any debris.
Replace the adaptor if the clearance is too narrow due to dirt or dust from the outflowing water.

Clog in the drainpipe
To avoid using HE High-Efficiency detergent
Is the drain hose kinked or clogged?
Keep an eye out for any obstructions in the drain line. Straighten the hose to ensure that water flows freely. Drain hoses, drainpipes, and utility sinks should be cleared of any obstructions. Secure the drain hose with the U-shaped drain hose form. For more information, refer to the provided documentation, such as the installation instructions.
Are you using HE High Efficiency detergent?
Only use HE (High Efficiency) detergents while washing your clothes. Excessive suds can be caused by using a detergent that isn’t HE or by using more detergent than the manufacturer recommends. The washer’s water removal will be slowed or halted by the buildup of suds.
Depending on the size of the load, just a modest amount of concentrated detergents labeled 2x and higher will be needed. Always adhere to the manufacturer’s instructions when using a product.
