On Whirlpool dishwashers, error code F9E1 has a documented potential cause of 'Long Drain': the dishwasher is not draining within the expected time. The identical content is republished on Maytag's and KitchenAid's product help sites.

Before you work on your dishwasher

  • Power: Unplug the dishwasher or switch off its circuit breaker before removing panels or touching wiring.
  • Water: Turn off the water supply valve before disconnecting hoses or the inlet valve.
  • Heat: Water and the heating element can be hot right after a cycle; let the dishwasher cool first.
  • Sharp debris: Wear gloves when reaching into the filter or sump; broken glass often collects there.
  • Stop: If you smell burning, see smoke or sparks, or find water near wiring, switch off the breaker and call a technician.
  • Disconnect power before accessing internal dishwasher parts: Unplug the dishwasher or switch off the circuit breaker that powers it before removing panels, the filter, or the drain pump cover, or before reaching into the sump.
  • Shut off the water supply before disconnecting hoses: Turn off the water supply before disconnecting the drain hose, siphon connection, or water inlet, or before pulling the dishwasher out for service.
  • Hot water and steam scald risk: Open the dishwasher door carefully during or right after a cycle. Hot water or steam can escape and cause burns; wait until water noises stop and steam subsides before fully opening the door.
  • Sharp debris near the filter and drain pump: Wear gloves and use caution when removing the filter, pump cover, or other parts for cleaning; broken glass or other sharp debris can collect near the drain pump impeller.
