3. DEFECT DIAGNOSIS FUNCTION
3-1. Error codes shown on Icemaker water supply control panel
2-5. Function Test
1. This is a forced operation for test, service, cleaning, etc. It is operated by pressing and holding the fill key for 3 seconds.
2. The test works only in the Icemaking Mode. It cannot be entered from the harvest or fill mode. (If there is an error code,
it can only be checked in the test mode.)
3.
Caution!
If the test is performed before water in the icemaker is frozen, the ejector will pass through the water. When the
fill mode begins (Stage 4), unless the water supply has been shut off, added water will overflow into the ice bin. 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
Harvest
Fill
Park Position
.
5. Five seconds after Stage 5 is completed, the icemaker returns to MICOM control. The time needed to supply water
resets to the pretest setting.
Error indicators in table can be checked only in TEST mode.
