Viking Dishwasher Error Code ECONO WASH + LED2

The ECONO WASH + LED2 error code on a Viking dishwasher indicates a high water level fault. This means the pressure sensor, specifically the HUBA pressure sensor, has detected that water inside the tub has risen beyond the acceptable threshold. The pressure sensor monitors tub water level by measuring air pressure changes in a chamber connected to the tub. When water rises too high, the pressure reading exceeds the normal operating range, and the control board triggers this fault code to halt the cycle and prevent overflow or flooding.

The HUBA pressure sensor is a critical safety and operational component. It translates water column height into an electrical signal that the control board reads to determine when to stop the inlet valve and when to begin draining. If this sensor fails, reads incorrectly, or if the air chamber or tubing connected to it becomes blocked or kinked, the board may receive a false high-level signal even when the actual water level is normal. Conversely, a stuck-open or leaking water inlet valve can cause genuine overfilling, which the sensor correctly detects.

Diagnosis begins with a normal reset to clear any transient fault, followed by a test cycle to check whether the error returns. If it returns, the pressure sensor and its associated tubing should be inspected for blockages, cracks, or disconnection. The inlet valve should also be checked for proper shutoff behavior, as a valve that does not fully close will continuously allow water to enter the tub even when the fill cycle is complete.
