2-5. Function TEST
1. This is a compulsory operation for TEST, SVC, cleaning, etc. It is operated by pressing the water supply control KEY for 3 seconds.
2. It operates in the Icemaking mode, but not in the Ice-Removing mode or water supply process. (If there is an ERROR, it
can only be checked in the TEST mode.)
3. If the water supply control KEY is pressed for 3 seconds in the Icemaking mode (no matter what condition the Ice-Making
tray is in) the Ice-Removing operation starts immediately. Water is not yet frozen, so water is poured instead of ice. If the
control doesn’t operate normally in the TEST mode, check and repair as needed.
4. After water is supplied, the normal CYCLE is followed: Icemaking
→
Dump
→
Fill
→
Park Position.
5. When Stage 5 is completed in the TEST mode, minimize MICOM in 5 seconds, the time needed to supply water resets to
the previous status in the TEST mode.
