Viking Dishwasher Error Code F3

Error code F3 on your Viking dishwasher indicates that the water level inside the appliance is higher than normal. This can lead to operational issues and potentially cause damage if not addressed promptly.

Overfilled Dishes: Excessive water usage due to overfilled dishes can trigger the F3 error.
Malfunctioning Float Switch: The float switch is a safety feature that monitors the water level. If it fails to operate correctly, it may not signal the dishwasher to stop filling with water.

1. Check for Overfilled Dishes:

Open the dishwasher and inspect the dishes. Ensure that none of the items are obstructing the movement of the spray arms or preventing the door from sealing properly.
Remove any excess or improperly placed items that could be causing the overfilling.

2. Inspect the Float Switch:

Locate the float switch, usually a small, dome-shaped device at the base of the dishwasher tub.
Gently lift and lower the float to ensure it moves freely. It should move up and down without any resistance.
Clean the float and the area around it to remove any debris that might interfere with its operation.

3. Verify Float Switch Operation:

Manually operate the float switch to see if it effectively interrupts the water flow when lifted.
Listen for a clicking sound, which indicates that the switch is functioning correctly.
If the float switch appears damaged or fails these tests, it may need replacement by a professional technician.

4. Adjust Loading:

Educate users on proper loading techniques to prevent overfilling. Distribute dishes evenly and avoid blocking the detergent dispenser or spray arms.

5. Run a Test Cycle:

Close the dishwasher door securely and run a test cycle to monitor for the F3 error.
If the error persists, despite following the above steps, it is advisable to seek professional assistance from technicians familiar with Viking dishwashers.

Addressing the F3 error promptly and accurately ensures the optimal performance of your Viking dishwasher and extends its lifespan.
