SERVICE MODE SELECTIONS
1. t01 Software version number test (UI, MC)
Check the software version.
2. t02 Error codes
Check for any error codes reported by the controls.
3. t03 User interface test
Verifies all LEDs operate correctly.
4. t04 Water valve and dispenser test
Verifies the dispenser motor works and can locate all 4 dispensers positions.
5. t05 Water level sensor test
Fills to overflow water level, then pumps out water.
6. t06 Drain Pump test
Test drain pump.
7. t07 Heater and Thermistor test
Test the heater and thermistor. The estimated temperature by fahrenheit is
displayed to SSD.
8. t08 Tumble test
Verifies washer tumbles (i.e., Wash Cycle).
9. t09 Spin test
Verifies washer spins. Note: No out of balance detection will be performed
here, so the washer will spin up regardless of the out of balance that is
placed in the drum.
