Viking Dishwasher Error Code 3-3

Error code 3-3 on a Viking dishwasher is a Pump Flow Error. It means the control board has detected insufficient or inconsistent water flow through the wash system. As a safety measure, the control will not allow the flow-through heater to activate until proper flow is restored. The first step is to confirm the water supply valve is fully open.

A reset may temporarily clear the 3-3 code, but it will return if the underlying flow problem is not corrected. The control monitors flow conditions actively during each cycle, so the fault will reappear whenever water movement falls outside acceptable levels. Addressing the root cause, such as a restricted supply valve or failing pump, is necessary for the error to stay cleared.

Repair costs vary depending on the failed component. If the issue is simply a closed supply valve, there is no parts cost involved. Inlet valve replacement typically ranges from $75 to $175 in parts and labor, while circulation pump replacement can range from $150 to $400 or more depending on parts availability and local labor rates. A control board replacement represents the higher end of potential repair costs.

Start by verifying the water supply shutoff valve under the sink is fully open. If flow is still insufficient, inspect the water inlet valve for mineral buildup or failure, check the circulation pump for obstructions, and examine the spray arms for clogged ports. If these components are functioning correctly, the control board may require evaluation by a technician.

The dishwasher is designed to disable the flow-through heater when the 3-3 code is active, which prevents heater damage from running without adequate water circulation. However, running the appliance with an unresolved flow problem can place additional strain on the circulation pump. It is best to diagnose and correct the fault before continuing regular use.
