My clrco2175 will only cycle once and then will not harvest ice

The symptoms you're describing could indicate several possible issues with your Ice-O-Matic ice maker. It's possible that the problem could be related to the timer or relay, but there are other components that could also be causing the issue.
Here are a few potential causes for the problems you're experiencing:

1. Thermostat: If the thermostat is malfunctioning, it may be causing the ice maker to freeze too long, preventing it from entering the harvest cycle properly.
2. Water inlet valve: A faulty water inlet valve can cause the purge valve to constantly dump water and can also prevent the water reservoir from filling up properly.
3. Control board: If the control board is faulty, it may not be properly controlling the ice maker's functions, including the harvest cycle.
4. Harvest assist: If the harvest assist mechanism is not functioning properly, it may not be able to break the ice free from the evaporator plate during the harvest cycle.

Given the complexity of diagnosing and repairing an ice maker, it's best to consult with a qualified technician to diagnose and fix the issue. You can search for local repair services in your area or contact the manufacturer for a referral.

Low room temperature - Most Scotsman ice makers won't produce ice when the temperature is below 55 degrees Fahrenheit. Make sure the machine is in a room or setting that is warmer. ... Faulty thermistor - A bad thermistor usually causes the bin to fill with too much ice.

E1, means low ice production
Ice machine cycle takes to long to call for a harvest. When this happens it should shut the whole unit down and then show the error code. Reset power supply, Turn off then Turn on the machine. Check for these problems. Gas leaking by the hot gas valve when in freeze mode, this valve should only let hot gas by when it is in a harvest mode. Check water control valve to make sure it is not letting water in during freeze cycle. Check water float switch to make sure it is not stuck calling for water during freeze cycle. Also make sure the machine is not in a hot location, the hotter the ambient surrounding air entering the condenser coil the longer it takes to make ice.

reduce the water pressure at the inlet valve so the trough fills up during harvest but doesn't overflow too much. There is a restrictor you can put in the valve entry, or you can just turn the tap to partly close it.

This machine has a cube size control. Which tells the machine when to go into a harvest. there is a harvest switch did you try to force it into a harvest and if you did, did it harvest. depending on ambient temperature from start of freeze cycle to harvest it should be making ice every 15 to 18 minuets and then go into a harvest. so start the ice machine and time it , run it for 18 minuets and force into a harvest. after ice drops check the ice bridge thickness. Bridge thickness should be about 3/16'' the ice dimple must not be DEEPER than 1/16". If this is good then we need to look at what is not working to harvest ice. The cube size control is a reverse - acting thermostat that controls the start of the timed freeze cycle. It must be set properly to prove the correct size cube bridge. When it is closed, an indicator light on the control board will be on. If you force it into a harvest and it harvest the ice with no problems and the ice is at the right thickness then replace the cube size control, but if dose not harvest the ice and you see the ice is at a good thickness and not to thick because if it is to thick it will freeze to every thing and will not drop. SYMPTOM. Unit freezes, but will not try to harvest. POSSIBLE CAUSE: Cube size control will not close; to check: Unplug water pump, switch unit OFF and then ON, in about 2 minutes the timed freeze light on the control board should be ON. PROBABLE FIX: If timed freeze light does not go ON, replace cube size control. SYMPTOM #2: Timed freeze light glows, but after 4 minutes unit dose not power hot gas nor purge valves Then replace control board.

Low ice production has multiple causes. First check condensing coil to see if they are dirty and not passing air. This is the most probable cause for low ice production. Next, measure freeze cycle time and harvest time. Freeze time is typically 20 to 30 minutes and harvest time is normally 1.5 to 3 minutes. If freeze time is long (> 35 minutes), first check water valve shuts after reservoir is full. If it does not shut off the water solenoid operated valve needs replaced. Second, find the harvest solenoid operated valve which branches off the compressor discharge and port high temperature gas into evaporator during harvest and see that evaporator side of harvest valve cools down to surrounding temperature in a few minutes 8 - 10 after freeze cycle starts and harvest time stops. If it does not cool off the valve is leaking by its seat and will require a technician to replace. Lastly, if long freeze cycle could be due to low refrigerant and will require and tech to charge properly. Ice machine are critically charged and a tech will know how to charge the right amount. Again, it is possible the metering device is not passing enough refrigerant and a technician can determine this by checking the superheat and subcool. Low subcooling <3 and a high superheat >20 typically indicate an txv (metering devise) needs replaced and will require a tech to replace.

This light is a harvest limit light. This light's primary function is to be on as water contacts the ice thickness probe during the freeze cycle, and remain on throughout the entire harvest cycle. The light will flicker as water splashes on the probe. The lights secondary function is to continuously flash when the ice machine is shut off on a safety limit, and to indicate which safety limit shut off the ice machine. Start up of machine after turned off. !. Before the ice machine starts, The water pump and water dump solenoid are energized for 45 seconds to purge old water from the water trough. This ensures that the ice making cycle starts with fresh water. The water fill valve energizes after 45 second water purge, and remains on until the water level probe is satisfied. 2. to pre-chill the evaporator, there is no water for the first 30 seconds of the freeze cycle. 3. The water pump starts after 30 seconds pre-chill. An even flow of water is directed across the evaporator and into each cube cell.

DO THE BASICS:
Change the water filter
Add ice machine cleaner and go by the directions.
What should be kept clean?
There are 5 things to keep clean:
1. The outside cabinet & door.
2. The ice storage bin.
3. The condenser.
4. The ice making system.
5. The ice scoop.
The ice storage bin should be sanitized
occasionally. It is usually convenient to sanitize the
bin after the ice making system has been cleaned,
and the storage bin is empty.
A sanitizing solution can be made of 1 ounce of
household bleach and two gallons of hot (950F. -
1150F.) water. Use a clean cloth and wipe the
interior of the ice storage bin with the sanitizing
solution, pour some of the solution down the drain.
Allow to air dry.

How to clean the condenser.
The condenser is like the radiator on a car, it has
fins and tubes that can become clogged. To clean:
1. Remove the kickplate.
2. Locate the condenser surface.
3. Vacuum the surface, removing all dust and lint.
Caution: Do not dent the fins.
4. Replace the kickplate.
Winterizing
1. Clean the machine as explained on the next
page.
2. Turn off the water supply.
3. Drain the water reservoir. See page 24, Spray
Pump Repair and follow the instructions to remove
the pump hose (step 2, bottom hose only).
4. Disconnect the incoming water line at the inlet
water valve.
5Remove control box cover and turn the timer
into the harvest cycle.
6. With the machine operating, blow air through
the inlet water valve; a tire pump could do the job.
7. Drain pump models should have about 1¤2 gallon
of RV antifreeze (propylene glycol) poured into the
ice storage bin drain.
Note: Automotive antifreeze must NOT be used.
8. Replace control box cover. Switch off and
unplug the machine.

CUBE ADJUSTMENTS
There are three items that may be adjusted: Cube
Size, Harvest Time, and Bin Level. Note: Cube
Size and Harvest Time adjustments should only be
done by a qualified service person.
Cube size control.
The cube size control should only be adjusted to
bring the cubes to the correct shape, the overall
size cannot be adjusted. Try to adjust the cube
size control when the ice machine is in the harvest
cycle, or in the first 10 minutes of the freeze cycle.
1. Open the door and remove the control box
cover.
2. Locate the cube size adjustment screw, and to
make fuller cubes, turn the screw clockwise about
1/4 turn. This will make the freezing cycle longer.
3. To shorten the freezing cycle and make cubes
that are not as full, turn the adjustment screw 1/4
turn counterclockwise.
4. After the next freezing cycle, the cubes should
have responded to the adjustment, if another
adjustment is required, do it early in the freeze
cycle.

No where can I find anyone who has solved Uline Echelon ice maker harvesting issues. My Clr 2060 only now produces 1" solid slabs. In harvesting cycle, will not release individual cubes. Anyone fix this problem?

The thickness probe should be approximatly 1/4 inch off of the evaporator.Sounds like you might have loose grids on the evaporator.turn the unit off and remove the curtain.use a flash light and inspect the grids.There should not be space in between the joints,if there is the ice will freeze behind the grids and not properly release when in harvest. Also gently pull at the grids,if they pull towards you or wiggle then they are separating. I have removed one of the grids and had the unit continue to run for sometime until the evaporator could be replaced.The plating being spotty causes release issues as well.Finally check the level of the machine,front to back and side to side.Not being level will also cause release problems
