Fast Time Down: Press Temp to advance to the next cycle
Error Codes: Press Spin button and “d” is displayed. Then to
view stored fault codes, turn Jog-Dial. Press Start/Pause while
the code is displayed to view the number of cycles since the er-
ror occurred.
Demo Mode: Press Pre Soak & Extra Rinse for 3 sec. Mode
cancelled when powered off.
Peripheral (Main PCB) input Tests: Press Extra Rinse and
“In” is displayed:
1. Then turn the Jog-Dial so that the Normal LED is turned on.
The Water Temperature will be displayed in Celsius.
2. Then turn Jog-Dial so that the Perm Press LED is turned on.
