Error Code Explained

What Does the Wolf LOW WATER Error Code Mean?

The Wolf CSO low water indicator alerts when the water reservoir level has dropped below the minimum required for the selected steam cooking program, or when the reservoir is not detected as properly seated. Steam cooking is not possible without adequate water in the reservoir.

Root Causes

Common Causes of the Wolf LOW WATER Error Code

  • 1
    Empty Water Reservoir
    The water reservoir has been depleted during a steam cooking session and needs to be refilled.
  • 2
    Reservoir Not Correctly Seated
    The water reservoir drawer is not fully closed and seated, causing the water level sensor to read no water.
  • 3
    Failed Water Level Sensor
    The sensor detecting water level in the reservoir has failed, falsely reporting the reservoir as empty.
