Maytag Dishwasher Error Code F9 E2 — Drain System Blockage
What this means
The F9 E2 error code indicates water is not draining from the dishwasher tub. This is typically caused by a clogged drain hose, a blocked garbage disposer connection, a kinked drain line, or a failed drain pump. Standing water will remain in the bottom of the tub after cycles.
Alternate codes: F9E2
Step-by-step fix
4 stepsCheck the garbage disposer
If the dishwasher drains through a garbage disposer, run the disposer to clear any blockage. Also verify the knockout plug was removed when the disposer was installed.
A forgotten knockout plug is the most common cause of drainage issues in new installations.
Inspect the drain hose
Check the drain hose behind the dishwasher for kinks, clogs, or improper routing. The hose should loop up high before connecting to the sink drain or disposer.
A high loop or air gap prevents sink water from backflowing into the dishwasher.
Clean the drain filter
Remove the bottom rack and clean the drain filter and fine mesh screen at the bottom of the dishwasher tub. Remove food particles and debris.
Clean the filter after every few loads to prevent buildup.
Check the drain pump
If the filter is clean and the hose is clear, the drain pump may be faulty. Listen for a humming sound during the drain cycle — humming without draining indicates a stuck pump.
Small items like broken glass or toothpicks can jam the drain pump impeller.
When to call a professional
If the drain pump is not operating and all other components are clear, a technician should replace the drain pump.
