Error codeF21
ApplianceWasher
Water that fails to leave a front-load Maytag washer is what F21 is about. Maytag’s wording is brief: F21 indicates a drain problem. Only a couple of checks are listed.
What to check
Follow the drain hose and see whether it is kinked.
Ask whether the hose might be clogged.
Reset the control by unplugging the washer for 5 minutes and plugging it in afterwards. Maytag says this can sometimes solve the problem.
When the hose is clear, the reset is done and F21 returns, arrange a technician visit.
Other front-load messages
F20: the reverse situation, with water not coming in.
