Viking Dishwasher Error Code High Water Level

The High Water Level error means the dishwasher's control system has detected water in the tub that exceeds the normal maximum fill threshold. The machine halts the cycle to prevent overflow. The detection is performed by a HUBA-type pressure sensor that monitors tub water level during operation.

Start by performing a reset and running a test cycle to see if the error reappears. If it does, inspect the HUBA pressure sensor and its connecting air tube for damage, blockages, or loose connections. If the sensor and tubing appear intact, the inlet valve should be tested for proper shutoff. Persistent faults after those checks may point to a control board issue requiring professional diagnosis.

Repair costs depend on the failed component. Replacing a HUBA pressure sensor typically runs in the range of $75 to $200 including parts and labor. A water inlet valve replacement generally falls in the $100 to $250 range. Control board replacement is the most expensive possibility, often ranging from $250 to $600 or more depending on the specific model and local labor rates.

A reset by cutting power at the breaker for 60 seconds may clear the error temporarily if it was caused by a one-time sensor glitch. However, if the underlying cause is a failing pressure sensor, a stuck inlet valve, or a wiring fault, the error will return once the machine runs again. A reset is a useful first diagnostic step, not a permanent fix.

You should not continue running the dishwasher until the cause of the error is identified and corrected. If the inlet valve is actually failing to close, operating the machine could result in tub overflow and water damage to surrounding cabinetry or flooring. Discontinue use until the fault is diagnosed.
