B. Sequence of Operation
The steps in the sequence are as outlined below.
1. Auto Fill Cycle
a) Auxiliary Code U-1, U-2, U-3, V-0, A-0
“AUTO FILL” lamp flashing and “RINSE,” “STANDARD,” or “LONG” lamp on.
If WT WLS is open when power is supplied and the “ON/OFF” button is pressed, the “AUTO FILL” lamp flashes and the auto fill cycle starts.
WV energizes. When BT WLF/S closes, WV de-energizes, RPM energizes and power is supplied to RFT. 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 then de-energizes for 10 seconds and power is cut to RFT for 10 seconds. RPM energizes/de-energizes (and power is supplied to and cut to RFT) the number of times set by the auto fill cycle setting. For details, see “Auto Fill Cycle” (service menu item 07) in “II.D.7.b) Service Menu Chart.” During the auto fill cycle, BT WLF/S opens/closes to energize/de-energize WV.
At the end of the auto fill cycle, there is a 5-second dwell time. CB checks WT WLS. If WT WLS is closed, BZ beeps, the “AUTO FILL” lamp goes off and the “READY” lamp comes on. If WT WLS is open, BZ beeps continuously, the “AUTO FILL” lamp goes off and “A1” flashes in the display. For details, see “III.B.3.a) Auto Fill Error (A1).”
Note:
1.If DS opens during the auto fill cycle, the “AUTO FILL” lamp goes off, RPM de- energizes, and power is cut to RFT. When DS closes again, the “AUTO FILL” lamp starts flashing and the unit resumes cycling RPM and power to RFT for the remaining number of times determined by the auto fill cycle setting.
2.BTH and WTH are de-energized during the auto fill cycle.
3.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.”
4.“STANDBY/CLEANING” button is inactive during the auto fill cycle.
b) Auxiliary Code A-1 and Later
"AUTO FILL" lamp flashing and "RINSE," "STANDARD," or "LONG" lamp on.
If WT WLS is open when power is supplied and the "ON/OFF" button is pressed, the "AUTO FILL" lamp flashes and the auto fill cycle starts.
WV energizes. When BT WLF/S closes, WV de-energizes, and RPM energizes. RPM energizes 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 then de- energizes for 10 seconds. RPM energizes/de-energizes the number of times set by the auto fill cycle setting. For details, see "Auto Fill Cycle" (service menu item 07) in "II.D.7.b) Service Menu Chart." During the auto fill cycle, BT WLF/S opens/closes to energize/de- energize WV.
At the end of the auto fill cycle, there is a 5-second dwell time. CB checks WT WLS. If WT WLS is closed, BZ beeps, the "AUTO FILL" lamp goes off and the "READY" lamp comes
