Viking Dishwasher Error Code E:07

E:07 on a Viking dishwasher indicates a water inlet valve fault where the control board detects water flow pulses occurring during a cycle phase when no water should be entering the tub. This typically means the inlet valve is stuck open or weeping water past its seal. The dishwasher will automatically run the drain pump for about one minute and then recheck the condition before displaying the error.

A power reset may temporarily clear the error code, but if the underlying inlet valve fault remains, the E:07 code will return once the dishwasher runs through a cycle and the control board detects water pulses during the wrong phase again. A reset should only be used as a diagnostic step to confirm whether the fault is intermittent, not as a permanent solution.

If the water inlet valve is the cause, parts typically range from $30 to $90 depending on the specific model, with professional labor adding $75 to $200 or more depending on your region and service provider. If the fault is traced to the control board, repair costs can be significantly higher, generally ranging from $150 to $400 or more for parts and labor combined.

A knowledgeable DIYer can inspect the water supply line, check for adequate water pressure, and examine the inlet valve screen for debris. Replacing the water inlet valve is a moderately involved repair that requires shutting off the water supply and disconnecting electrical connectors, and is within reach for experienced DIYers. If the valve is not the issue, diagnosing a faulty control board typically requires professional testing equipment.

Running the dishwasher with an active E:07 fault is not recommended. A valve that is stuck open or weeping can allow water to accumulate in the tub uncontrollably, increasing the risk of an overflow or water damage to surrounding cabinetry and flooring. It is best to keep the dishwasher off until the inlet valve has been inspected and repaired.
