Cycle Steps 1. Auto Fill Cycle 2. Ready Cycle (Unit Inactive) 3. Wash Cycle 4. Rinse Cycle
• SPS must be closed for RPM to energize • Cycle started by wash start switch • Cycle started by rinse start switch
• RPM time: (service menu item 03) • SPS must be closed for WPM to energize • SPS must be closed for RPM to energize
• RFT de-energized during Auto Fill Cycle • The upper spray arm WPM starts first,
followed by the lower spray arm WPM
