4.If BT WLF/S fails, BT BUWLF/S assumes control. If BT BUWLF/S remains closed for 1 minute, o1 or o2 error appears in the display. For details, see "III.B. Error Codes."

5.The wash/rinse start switch is inactive during the auto fill cycle.

2. Ready Cycle (Unit Inactive)

"READY" lamp and "RINSE TEMP." or "WASH TEMP." lamp on.

WT WLS closed. After a rinse cycle, RPM de-energizes, and the "READY" lamp comes on. WTH energizes when WT water temperature is at the wash temperature setpoint or lower. WTH de-energizes when WT water temperature is 5°F (3°C) above the setpoint. For details, see "Wash Temperature Setpoint" (service menu item 04) in "II.F.7.b) Service Menu Chart."

BTH energizes when BT water temperature is 3°F (2°C) below the rinse temperature setpoint or lower. BTH de-energizes when BT water temperature reaches the setpoint. WV energizes/de-energizes when BT WLF/S opens/closes. For details, see "Rinse Temperature Setpoint" (service menu item 05) in "II.F.7.b) Service Menu Chart."

Note:

1.The thermistors control WT and BT water temperatures.

2.If one of the thermistors has an open or short circuit, WTH or BTH de-energizes and an error code appears in the display.

3.WTH and BTH are controlled regardless of SPS operation.

3. Wash Cycle/Rinse Cycle

"WASH" lamp and "RINSE TEMP." or "WASH TEMP." lamp on.

When a rack is loaded from the wash compartment entrance and the wash start switch closes, WPM energizes, power is supplied to DFT and the "WASH" lamp comes on. WPM draws water from WT and sends it through the wash spray arms. The upper spray arm WPM starts first, followed by the lower spray arm WPM. Then, the conveyor starts to move the rack. After the wash start switch opens and the extended wash cycle time (factory default: 30 seconds) has expired, WPM de-energizes and power is cut to DFT. For details, see "Extended Wash Cycle Time" (service menu item 01) in "II.F.7.b) Service Menu Chart." When the rinse start switch closes, RPM energizes and power is supplied to RFT. 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 the rinse start switch opens and the extended rinse cycle time (factory default: 15 seconds) has expired, RPM de- energizes, power is cut to RFT, the "WASH" lamp goes off and the "READY" lamp comes on. For details, see "Extended Rinse Cycle Time" (service menu item 02) in "II.F.7.b) Service Menu Chart."

After both WPM and RPM de-energize, the conveyor stops. If SP is opened during operation, SPS opens, WPM and RPM de-energize and the conveyor stops. If the wash/ rinse start switch is closed when SPS closes, WPM and RPM energize and the conveyor restarts.

Note:

1.If WT WLS opens after WPM energizes, WPM de-energizes and RPM energizes for the supplementary fill cycle time (factory default: 450 seconds) to supply hot water into
