What the F21 Code Means on a Maytag Washer
The F21 error indicates Drain System Fault. The appliance cannot drain water within the expected time, usually due to a clog, kinked hose, or failed drain pump. On most Maytag units, the display will hold the code until the fault clears or power is reset. If the code returns immediately after reset, an underlying component failure is likely.
Manufacturers design these codes so technicians can narrow diagnosis quickly. For homeowners, the key takeaway is whether the issue is user-correctable (filter, supply, door switch) or mechanical (pump, motor, sensor, control board).
