"STANDBY/CLEANING" Button Start

When the "READY" lamp is on, the unit starts operation in the selected mode when the "STANDBY/CLEANING" button is pressed.

"STANDARD" or "LONG" lamp flashing (depending on the wash mode selected). WPM energizes and power is supplied to DFT for the length of time set by the wash cycle time setting. For details, see "Wash Cycle Time (Standard Mode) or "Wash Cycle Time (Long Mode)" (service menu item 01 or 02) in "II.D.7.b) Service Menu Chart."

WPM draws water from WT and sends it through the wash spray arms. When the wash cycle time has expired, CB checks BT WLF/S. If BT WLF/S is open, the wash cycle is extended and the lights in the display rotate. If BT WLF/S is closed, the unit enters a 5-second dwell time and then proceeds to the rinse cycle. If BT WLF/S does not close within 10 minutes after the auto fill cycle starts, "A2" appears in the display, and the unit shuts down. During the 5-second dwell time, detergent containing wash water on the door liner and inside the wash spray arms flows back into WT.

During the wash cycle, WTH energizes when WT water temperature is at the wash temperature setpoint or lower. For details, see "Wash Temperature Setpoint" (service menu item 04) in "II.D.7.b) Service Menu Chart." WTH de-energizes when WT water temperature is 5°F (3°C) above the setpoint. BTH energizes when BT water temperature is 3°F (2°C) below the rinse temperature setpoint or lower. For details, see "Rinse Temperature Setpoint" (service menu item 05) in "II.D.7.b) Service Menu Chart."

BTH de-energizes when BT water temperature reaches the setpoint. WV energizes/de- energizes when BT WLF/S opens/closes.

Note: If DS opens during the wash cycle, BZ beeps, the "STANDARD" or "LONG" lamp goes off, the "READY" lamp comes on, WPM de-energizes and power is cut to DFT. When DS closes again (if service menu item 11 is set for door start), the "STANDARD" or "LONG" lamp starts flashing and the unit starts a new wash cycle.

4. Rinse Cycle

The rinse cycle starts automatically after the wash cycle. When the mode is set to "RINSE," the rinse cycle can also be started by either the door switch or the "STANDBY/CLEANING" button. For details, see "Wash/Rinse Cycle Start Initiation" (service menu item 11) in "II. D.7.b) Service Menu Chart."

Door Switch Start

When the "READY" lamp is on, the unit starts operation in the selected mode when DS closes.

Note: If the "STANDBY/CLEANING" button is pressed when the "READY" lamp is on, the "READY" lamp goes off and the "STANDBY" lamp comes on. When the "STANDBY" lamp is on, the unit will not operate even if DS closes. To cancel standby, press the "STANDBY/CLEANING" button.

"STANDBY/CLEANING" Button Start
