Most Common Causes
Incomplete Descaling
DIY Possible
Heavy scale buildup from Arizona hard water may require multiple descaling cycles to fully clear.
Scale Sensor Coated
Requires Service
The sensor that detects scale buildup is itself coated with mineral deposits, giving false readings.
Other Possible Causes
Residual Scale in System
Scale in areas the descaling cycle doesn't fully reach continues to trigger the alert.
Control Board Memory
The control board may need to be reset after a successful descaling cycle.
