Viking Dishwasher Error Code F10: Blocked Spray Arm... | appliancefaults.com

Technical Background:

The F10 error code on a Viking dishwasher typically indicates a problem with the water circulation system. The Main Control Unit (MCU) monitors the flow of water and pump motor current. If the flow is restricted or the motor current is abnormal, the MCU triggers the F10 fault. This usually involves voltage readings from sensors or current sensors on the circulation pump motor circuit. If the MCU detects an out-of-range signal, it generates the error.

Symptoms:

The dishwasher displays the F10 error code. Dishes are not cleaned properly, especially those on the upper rack. The dishwasher may be making unusual noises during the wash cycle.

Possible Causes:

Blocked spray arm nozzles
Debris in the pump impeller
Faulty circulation pump motor
Damaged spray arm
Low water pressure
Control board malfunction

Solution:

1

Disconnect power to the dishwasher at the breaker panel.
2

Visually inspect the upper and lower spray arms for any blockages. Remove and clean any debris with a small brush.
3

Check the pump impeller for obstructions. Access the pump housing (typically behind the lower spray arm) and remove any foreign objects.
4

Verify water inlet valve operation using a multimeter to test for 120V AC when the dishwasher is filling.
5

Inspect the circulation pump motor windings for continuity using a multimeter. A lack of continuity indicates a faulty motor.
6

Check the water pressure at the supply line. It should be at least 20 PSI.
7

If all other components test good, consider replacing the control board. This is rare, but possible.

Safety Warning:

Always disconnect power to the dishwasher before performing any repairs. Use Lock Out Tag Out (LOTO) procedures to prevent accidental re-energizing of the circuit. Some components may retain a high voltage charge even after the power is disconnected.

Prevention:

Regularly clean the spray arms and filter to prevent blockages. Avoid placing large food particles in the dishwasher. Periodically run a dishwasher cleaner to remove buildup.

Expert Tip:

Viking dishwashers often have a service mode. To access it, press and hold the 'Start/Reset' and 'Heated Dry' buttons simultaneously for 5 seconds. This will allow you to run diagnostic tests on the various components.

Frequently Asked Questions

•How do I access the pump impeller on my Viking dishwasher?

Typically, you need to remove the lower spray arm and the filter assembly. Then, you should see a cover plate that can be removed to access the pump impeller. Be careful when removing any parts, and make sure to note the order of assembly.

•What voltage reading should I expect on the circulation pump motor?

The circulation pump motor typically operates on 120V AC. You should measure this voltage at the motor terminals when the dishwasher is in a wash cycle. If you don't see voltage, check the wiring and control board.

•Where can I find a wiring diagram for my Viking dishwasher model?

Wiring diagrams are usually located inside the dishwasher, often taped to the back panel or inside the control panel. You can also try searching online using your specific model number, or contacting Viking directly for assistance.
