Arizona hard water has created scale beyond what a single cycle can remove.
Wrong Descaling Solution
DIY Possible
Using vinegar or non-approved descaler doesn't dissolve minerals effectively.
Other Possible Causes
Flow Sensor Coated
The water flow sensor is coated with scale, giving incorrect readings.
Internal Blockage
Scale has blocked internal passages that the descaling cycle can't reach.
