Identify the Cause of the Stuck Descale Light
The most common reason for a stuck descale light is mineral buildup or a faulty sensor. Ensure the machine actually needs descaling by checking the water hardness setting and recent usage. If the machine is new or has been recently descaled, the sensor or circuit might be malfunctioning.
