DIAGNOSTICS AND TROUBLESHOOTING (Cont.)
Tachometer Verification Mode
To access Tachometer Verification Mode, perform steps 1 and
2 of Activating the Service Diagnostic Modes. Toggle the cycle
selector knob until the status LEDs correspond as follows:
n "SOAK/WASH and DONE" LEDs On
FILL SOAK/
Wash
NOTE: Status LED names may vary between makes and models.
Press the START button to begin tachometer verification mode.
n Tachometer verification uses the status LEDs to represent the
tachometer frequency (basket RPM).
For example, slowly turn the basket by hand; as the basket
turns, the DONE, FINAL SPIN, RINSE, and SOAK/WASH status
LEDs will illuminate one at a time in a visually repeating cycle.
The LED timing is derived from the tachometer signal itself.
