CS0415 Cleaning Indicator Issue:
Symptoms: Cleaning light red after less than 2 weeks of usage.
Problem : hung slabs or simulated hung slabs ( run with no water for 48 hours) is the cause for
various reasons.
Observation : Customer sees red clean light on
To re-set the clean light : Customer/ Tech will have to let the clean cycle run all the way. 70 minutes
the light will go from blinking green ( during cleaning ) to solid green. But 70 minutes is a long time for a
tech to wait.
Following could cause faster/more frequent hung slabs:
1. Low or no fill on water
a. line pressure low,
b. fill tube alignment ( pointing down the standpipe drain )
c. RO water system capacity,
d. kinked lines to or inside product
e. leaking lines inside or outside the product
f. check fill level in reservoir ( should be within 1/2" of standpipe)
.
2. Leaking reservoir
a. drain cap
b. reservoir drain pump gasket
c. Goose neck drain tube fully seated and in vertical orientation ( slow siphoning of water during
recirculation would be observed)
d. reservoir level ( less probable)
3. Obstructed Cutter grid
a. foreign object on grid
b. thermistor wire blocking grid
c. ice guide missing or loose ( blocking slab as it travels)
d. cutter grid unplugged
4. Water quality causing stacking slabs
a. Through control diagnostics change to delay harvest mode ( high mineral content water
makes ice difficult to cut )
b. verify in diagnostics on control. Will get blinking clean light in step #8.
5. Unlevel product
6. Evaporator
a. dirty , especially the front of side walls ( make slab hang on plate)
b. weld slag on back corners of the evap plate
c. toed in evap plate
1. front should be wider than the back
2. top should be wider than the bottom
d. verify alignment between evap side walls and water return into the iceguides.
