Error code guide
Whirlpool dishwashers report faults in the same 'F#E#' format as Whirlpool laundry. Models with a display show the code directly. Models without one blink the Clean light: count the first set of flashes (the F number), wait for the short pause, then count the second set (the E number). Seven flashes, a pause and one flash means F7E1.
| Code | Meaning |
|---|---|
| F9E1 | Long drain — the dishwasher took too long to drain or isn't draining. |
| F8E4 | Water detected in the drip tray (base). |
| F6E4 | Overfill or float problem — the float switch is reporting too much water. |
| F7E2 | Wash motor error. |
| F6E1 | User interface / main control communication error. |
| H2O | No water detected. |
Long drain — the dishwasher took too long to drain or isn't draining.
When to call: If everything is clear and it still won't drain, the drain pump likely needs replacing.
Water detected in the drip tray (base).
When to call: Turn the water off under the sink and call — a hidden leak can ruin cabinets and flooring.
Overfill or float problem — the float switch is reporting too much water.
When to call: If the float is free and the code returns, the inlet valve or float switch needs service.
Wash motor error.
When to call: If the code reappears, the motor needs testing.
User interface / main control communication error.
When to call: If it returns, the control or wiring needs a technician.
No water detected.
When to call: If water is on and it still won't fill, the inlet valve likely needs replacing.
Disconnect power for 30 seconds — unplug a corded dishwasher, or switch off the breaker for a hard-wired one — then restore power and start a new cycle.
