Viking Dishwasher Error Code Cycle Error - Fill Sensor Error

This error means the HUBA pressure sensor detected a problem during the water fill phase of the wash cycle, causing the dishwasher to stop. The sensor monitors water level inside the tub, and when it reports an abnormal or absent reading, the control board halts the cycle and logs the fault. The cause can be a failed sensor, a blocked pressure hose, wiring problems, or an issue with the water supply.

A reset may clear the error code temporarily, but if the underlying problem with the pressure sensor, hose, wiring, or water supply is not corrected, the fault will return the next time the fill cycle runs. Resetting is useful for confirming whether the error is intermittent, but it does not substitute for proper diagnosis and repair.

Repair costs vary depending on the root cause. If only the pressure hose needs clearing or a connector needs reseating, costs may be limited to a service call fee, typically in the range of $75 to $150. Replacing the HUBA pressure sensor or the water inlet valve adds parts costs, and total repair expenses including labor can range from $150 to $400 or more depending on the technician and parts pricing in your area.

Start by inspecting the HUBA pressure sensor and the small hose connected to it for clogs, kinks, or cracks. Check the wiring connector at the sensor for corrosion or looseness. If those components appear intact, test the water inlet valve for proper flow and verify adequate household water pressure. If the sensor itself tests out of range, it will need to be replaced.

The dishwasher will typically not complete a cycle when this error is active, so continued use is not possible until the fault is resolved. There is no immediate safety hazard such as flooding in most cases, since the fill cycle is interrupted rather than allowed to overfill. However, operating the appliance repeatedly with a known sensor or water supply fault is not recommended, as it could mask a developing issue with the inlet valve.
