How to fix KitchenAid Sanitize light flashing
Get hot water to the sink first
Run the kitchen hot tap for about 30 seconds before you start the dishwasher. Incoming water should be at least 120°F (49°C).
Keep the door shut
Opening the door during a Sanitize cycle lets heat out and can stop it reaching temperature. Add forgotten dishes before you start.
Reset and retry
If the light still flashes, do a 30-second power reset and run the cycle again.
When to call a technician
If the light keeps flashing with hot water at the sink and the door left closed, have the heating system checked.
