Troubleshooting guide

it from the drain hole. The water in the reservoir will 
flow down the drain.
5. Replace the overflow tube after all of the water has 
drained from the reservoir.
6. Start the cleaning cycle as follows:
a. Touch and hold the ON/OFF button (Figure 9, 1).
b. Touch and release the LIGHT button (Figure 9, 4) 
three times, then release the ON/OFF button 
(Figure 9, 1).
c. The display (Figure 9, 3) will show “CL” to confirm 
the beginning of the cleaning cycle. 
7. When water begins to flow over the evaporator 
(approximately three minutes), add one package of U-
Line Ice Machine cleaner to the water reservoir.
8. Reinstall inside front cover.
9. When the self-cleaning process stops (approximately 45 
minutes) the unit will remain off for an additional 15 
minutes. When clean cycle is completed, display will 
automatically switch back to set temperature and unit 
will run as normal operation.
10. Clean the storage bin (See INTERIOR CLEANING). 
Sanitize the bin with a solution of 1 tablespoon of 
bleach in 1 gallon of warm water. Rinse thoroughly 
with clean water.
11. To ensure that the drain system is working properly, 
pour 1 gallon of cool, fresh water into the ice bin. The 
water should drain freely. If your unit is equipped with 
a drain pump, it should drain the ice bin.
When ice production resumes, the water fill valve will 
energize, fill the water reservoir, and shut-off after three 
minutes. The compressor begins to operate and water 
flows over the evaporator assembly (ice cube tray). 
Initially, the water flow may not be uniform, causing 
uneven sized cubes or water to spill into the ice storage 
bin. This is a normal situation that will correct itself within 
the first 24 hours of operation. 
IMPORTANTIMPORTANT
• Discard all ice produced in the first harvest.
• Should power to the unit be interrupted during 
the self-clean cycle, it will be necessary to repeat 
the complete cleaning cycle after power is 
restored. 
Inlet Screen
Interval - Every Twelve Months
The solenoid valve inlet screen must be cleaned at least 
once each year as follows:
1. Shut off the water at the main supply valve.
2. Pull the unit out to access the back panel.
3. Disconnect electrical power to the unit.
Figure 12
4. Disconnect the hose connector 
(Figure 12, 1)
 from the 
water solenoid valve 
(Figure 12, 2)
.
5. DO NOT remove the inlet screen 
(Figure 12, 3)
 from 
the water solenoid valve. Use a toothbrush to gently 
clean any sediment from the inlet screen. 
6. Re-connect the water supply hose connector 
(Figure 
12, 1)
 to the water solenoid valve 
(Figure 12, 2)
. 
Tighten the connector securely.
7. Open the water main supply valve and check for leaks 
at the water hose connection. Ensure that the water 
supply line is not kinked.
8. Reconnect power to the unit before re-installing.
9. Make sure the drain system is working properly and the 
drain hose is not pinched or kinked. Pour 1 gallon of 
cool, fresh water into the ice bin. The water should 
drain freely. If your unit is equipped with a drain pump, 
the pump should drain the ice bin.
10. To ensure that the drain system is working properly, 
pour 1 gallon of cool, fresh water into the ice bin. The 
water should drain freely. If your unit is equipped with 
a drain pump, it should drain the ice bin.
Ice Cube Thickness Adjustment
Interval - As Required
Ice thickness adjustments are made using the control 
panel as follows:
Figure 13
1. To enter the thickness adjustment mode:
a. Touch and hold the UP ARROW button (Figure 
13, 1).
