Maytag Atlantis intermittently misses drain stages

The problem

A 14-year-old Maytag Atlantis washer completed wash and refill stages but did not start either drain stage unless the timer was manually advanced. The user also found that briefly opening and closing the lid at the point where draining should begin would immediately trigger drain and spin.

Likely cause

The accepted reply said a faulty lid switch was unlikely because the lid switch should cut the motor and the drum was reported to stop and restart normally when the lid was opened and closed during spin. The strongest suggested cause was a sticking drain pump, though this was noted as unusual. A partial blockage in the pump, filter, or sink u-bend connection was also suggested as a possible cause.

What fixed it

Check the drain pump and filter for blockage, and if the drain hose connects to a sink u-bend, check that connection for a partial blockage. The exact repair was not confirmed in the discussion.

Checks to try

• Observed that the washer would drain and spin only after manually advancing the timer
• Observed that briefly opening and closing the lid when drain should start would trigger drain and spin
• Checked lid-switch behaviour during spin: opening the lid stopped the drum and closing it restarted spinning
• Recommended check of drain pump for sticking or blockage
• Recommended check of pump filter for blockage
• Recommended check of sink u-bend connection for partial blockage
