Maytag Washer Error Code d8/F21

The d8/F21 code means the washer took longer than 8 minutes to drain without the pressure switch reaching its reset level, which signals to the control board that draining did not complete successfully. The machine stops the cycle to prevent damage and alert you to the problem. This is almost always related to a restriction in the drain system, such as a clogged filter, a sealed drain hose connection, or a failing pump.

Clearing the error code will allow the washer to restart, but the code will return if the underlying drainage problem is not resolved. To clear it, unplug the washer for one minute or use the control panel reset sequence for your specific model. Always address the root cause before assuming a reset is a permanent fix.

If the fix is simply repositioning the drain hose or cleaning a clogged pump filter, the repair costs nothing beyond your time. If the drain pump needs to be replaced, parts typically range from $30 to $100 depending on the model, plus labor if you use a technician, which can bring the total to $150 to $300 or more. A defective pressure switch is generally a lower-cost part, usually $15 to $50, and is more straightforward to replace.

Start by unplugging the washer and checking that the drain hose is not sealed tightly into the standpipe, since an air gap is required for proper drainage. Next, locate and clean the pump filter or coin trap, removing any lint or debris. If the hose and filter are clear, run a drain cycle and listen to confirm the pump is running and moving water. If the pump runs weakly or not at all, it may need to be replaced.

You should not continue running cycles while this code is active, because the tub may still contain standing water and the washer has halted to protect itself. Running additional cycles without fixing the drain issue can strain the pump motor and potentially cause water to remain in the drum for extended periods. Resolve the drainage problem first before resuming normal use.
