Viking Dishwasher Error Code 3-2

Error code 3-2 on a Viking dishwasher indicates a Pump Flow Error. The control board has detected that water flow through the wash system is insufficient or inconsistent. As a protective measure, the control will not allow the flow-through heater to activate until proper flow is restored. This code is triggered during the service cycle.

A reset may temporarily clear the code from the display, but the error will return during the next service cycle if the underlying flow problem has not been corrected. The control is designed to recheck flow conditions each time the cycle runs, so the root cause must be addressed to prevent the code from reappearing.

If the fix is as simple as clearing a clogged filter or fully opening the supply valve, there may be no parts cost at all. If the wash pump motor has failed and needs replacement, parts and labor costs typically range from $150 to $400 or more depending on the specific model and local service rates. Getting a diagnostic visit from a qualified technician will give you a more precise estimate for your situation.

Start by confirming the water supply valve is fully open and the inlet hose is not kinked. Next, clean the sump filter and check the spray arms for blockages. If those steps do not resolve the issue, the wash pump motor may need to be tested and potentially replaced. Resolving the underlying flow restriction is the only way to clear this error.

The dishwasher is designed to block heater activation when this error is present, which is a built-in safety feature to prevent the heater from running without adequate water flow. You should not attempt to bypass this protection. Identify and correct the flow issue before running the unit through a normal wash cycle.
