Quick answer
The F9E1 code on built-in Whirlpool dishwashers is a long drain. Work through the drain line and cycle power.
Model note: Whirlpool reuses codes across series and model years, so F9E1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

A plain-language reading of the code — always confirm against your model’s documentation.
Mean
F9E1 reports a long drain because the dishwasher is not draining.
Understanding F9E1
A long drain is the potential cause Whirlpool gives for F9E1. The water is not leaving the dishwasher, so the help text starts with the drain line.
Drain line checklist
Pull the filter and clean it well under running water.
Follow the drain hose from the back of the dishwasher to the sink, and look for a kink, a pinch or a clog. It should be routed on the correct side, inside the frame.
With a garbage disposer, run it to clear anything caught, and confirm the knockout plug was removed from its inlet on a new installation.
If an air gap is used, refer to its maker for taking off the cap and clearing blockages.
Reset the control
Resetting can sometimes solve this the way restarting a computer does. Leave the dishwasher without power for 30 seconds, either unplugged or with the home panel breaker off.
Other codes to compare
A failing drain motor is F9E2. The drain-and-lockout fault is F8E4.
