What Does Error Code CAL Mean on a Whirlpool Dishwasher?
Calibration needed — sensor recalibration required.
CAL is a status indicator, not a fault code. The control board flags that the dishwasher's sensors — commonly the turbidity (soil) sensor and temperature sensing used to gauge water clarity and heating — need to re-establish baseline readings. It appears when stored calibration data is lost, usually after a power interruption or a control board reset. Unlike true error codes, CAL requires no parts and clears on its own once an uninterrupted cycle lets the sensors self-calibrate against clean water.
