Overview of Cycles
• After pressing the ON/OFF button, all LEDs will light, the digital display will show 88, and the buzzer will
beep.
• The estimated cycle time will be displayed as a two-digit number. If the cycle time exceeds 99 minutes,
the seven segment display will show 2H. If the cycle time is less than or equal to 99 minutes, the actual
estimated cycle time is displayed.
• The control makes an End-of-Cycle Alert for 1 second every 2 minutes (with a maximum of 4 beeps) for
any mode (regardless of whether delay was selected or not) after the end of any cycle.
• Cancel/Change cycle: After a cycle has started, open the door and hold the Select button down for 3
seconds. After 3 seconds, the machine will beep and the display will select the next cycle to the right. If
left on any cycle with the door closed, the machine will drain and start that new cycle automatically.
• Delay start – Select 1 to 24 hours as the amount of time to delay the start of the cycle. This will be
displayed as 1H, 2H, etc. The delay start display never shows minutes.
• When the door is closed, the display will turn off after 3 minutes regardless of a time delay. Opening the
door will turn the display back on. During the cycle run, the selected cycle LED will flash on/off.
• This model does not contain a Demo mode.
Sanitize wash cycle definition:
The Sanitized LED will only be turned on at the end of the sanitize wash cycle if the following two conditions
are met during the cycle:
1. An internal calculation the board makes based on several heat factors.
2. The water temperature in the final rinse is greater than or equal to 150°F.
The maximum time for the final rinse in the sanitize wash cycle is 60 minutes. If both of the above conditions
are met prior to the 60 minute limit, the final rinse will end immediately and both the Sanitized light and
Clean LED will turn on. If either condition is not met at the end of the 60 minute limit, the final rinse will end
and the Sanitized light will not turn on.
