Whirlpool Dishwasher F9 E1 error code
Difficulty: Easy
·
Cost: $0–$80
·
Duration: 15–20m
The F9 E1 error means your Whirlpool dishwasher is not draining properly. This is most commonly caused by a kinked or clogged drain hose, a blocked air gap, or a garbage disposal that has not been cleared or had its knockout plug removed for new installations. Checking these components and disconnecting power for 30 seconds resolves most cases.
Common causes
- Drain hose is kinked, pinched, or clogged
- Garbage disposal knockout plug was not removed during installation — for new dishwasher connections
- Garbage disposal is clogged and blocking drainage
- Air gap is blocked with debris
- Drain pump has malfunctioned
