How do I run the Calibration cycle on my washing machine?
Power off and then power on the washer, then hold down Temp. and Delay End simultaneously for 3 seconds to enter Calibration mode until the 'CB' message appears. Press Start/Pause to run the Calibration cycle, and the drum will rotate clockwise and counter-clockwise for about 3 minutes. When the cycle is complete, '0' appears on the display and the washer will turn off automatically.
