"RINSE" lamp flashing.
RPM energizes and power is supplied to RFT for length of time set by the rinse cycle time setting. For details, see "Rinse Cycle Time" (service menu item 03) in "II.D.7.b) Service Menu Chart." RPM draws water from BT and sends it through the rinse spray arms. Rinse aid is fed into the rinse water line and sprayed from the rinse spray arms together with rinse water. Any excess water in WT drains through the overflow pipe. After RPM de- energizes, the unit enters a 1-second dwell time. After the dwell time, CB checks BT WLF/S. If BT WLF/S is open, the lights in the display rotate until BT WLF/S closes. If BT WLF/S is closed, BZ beeps for 2 seconds, the "READY" lamp comes on, and the unit returns to the ready 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 1-second dwell time, hot rinse water on the door liner and inside the rinse spray arms flows back into WT. The "RINSE" lamp keeps flashing.
During the rinse 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 rinse cycle, BZ beeps, the "RINSE" lamp goes off, the "READY" lamp comes on, RPM de-energizes, and power is cut to RFT. When DS closes again (if service menu item 11 is set for door start), the unit starts a new cycle in the selected mode.
5. Drain
This unit does not have a drain valve.
The overflow pipe in WT drains excess water from WT. To completely drain WT, remove the overflow pipe.
To drain BT, first move the power switch (GFCI) to the "OFF" position. Turn off the power supply. Lockout/Tagout to prevent the power from being turned back on inadvertently.
Use BT drain hose to drain BT. WARNING! To avoid possible burns, allow BT water temperature to fall below 104°F (40°C) before draining.
