Start with the safe check: The Clean light flashes seven times, pauses, then flashes once
Confirm that the repeating sequence is seven flashes, a pause, then one flash—not seven total flashes with no second group.
Run the next safe step: The Clean light flashes seven times, pauses, then flashes once
Record the pattern as F7-E1 only after seeing the complete repeat. Use Whirlpool’s model-specific code guidance for the exact dishwasher before replacing a part.
What success looks like: The Clean light flashes seven times, pauses, then flashes once
The full code and model number are recorded and the supported model-specific check has either resolved the issue or identified a service need.
Stop and escalate: The Clean light flashes seven times, pauses, then flashes once
If the pattern returns after the supported checks, arrange Whirlpool service rather than guessing at a heater, sensor, or control.
