If you are searching for “why is my nugget ice maker squealing,” start by identifying when the sound happens and comparing it with the sounds described in your product manual.
For the CB24M-B nugget ice maker, the user manual identifies several sound-related situations. It states that a slight sound during the first moments after startup is normal because the appliance performs an automatic self-check. It also states that pumping or gurgling can become louder when the water level is low and the pump is drawing the remaining water from the tank.
The manual does not provide a specific diagnosis for a sound described as “squealing.” For that reason, this guide does not assign an unconfirmed cause to the noise. Instead, it explains the approved checks, cleaning steps, and safety instructions provided for the CB24M-B. If the problem continues after following those instructions, contact customer support.
Start With the Time the Noise Occurs
When trying to understand why your nugget ice maker is squealing, the first useful question is: when did the noise start?
A sound that appears immediately after startup is different from a sound that begins after moving the appliance, when water is low, or after the machine has been operating for some time.
The CB24M-B manual specifically notes that the machine may make a slight sound during the first moments after startup. This is described as part of its automatic self-check and does not affect performance.
If the sound is brief and only happens as the machine starts, allow the appliance to continue its normal cycle. If the issue remains present, use the remaining manual-based checks in this guide.
Did the Sound Begin After Delivery or Moving the Ice Maker?
The CB24M-B manual gives specific instructions for first use after transport.
During transportation, the appliance may tilt or experience movement. The manual instructs users to place the unit upright for six to eight hours before first use. This allows the refrigerant and refrigeration oil to settle properly.
The manual also warns that starting the machine too soon after it has been tilted may cause abnormal noise or permanent damage to the compressor.
If the appliance was recently delivered, moved, tilted, or transported in a vehicle, turn it off and ensure it is standing upright on a stable surface. Allow it to remain upright for the recommended time before operating it again.
If the appliance has been stored in a cold environment, the manual instructs users to wait at least three hours for it to warm to room temperature before plugging it in.
Check the Water Tank and Water Level
The CB24M-B has a water tank and a water filter. The manual states that a louder pumping or gurgling sound may occur during operation when the water is running low and the pump is drawing the remaining water from the tank.
Before making any other changes, check whether the water tank needs refilling.
Use fresh potable water. Fill the tank below the MAX line. Do not overfill the tank. The manual also advises against using water that is microbiologically unsafe or of unknown quality.
The Add Water indicator should remain off during normal water supply. If the Add Water indicator stays on, the troubleshooting guide instructs users to:
- Fill the tank to the MAX level and press to restart;
- Remove the water filter and check or clean it when necessary;
- Confirm that the water tank is correctly installed;
- Check water inlet pipelines, if applicable.
The manual notes that distilled, demineralized, or filtered water may help prevent scale buildup and extend the life of the ice maker.
Confirm Correct Placement Before Use
The CB24M-B should be placed upright on a flat, level surface.
The user manual specifies at least 15 cm, or 6 inches, of clearance on both sides and at the back of the appliance. Keep the area around the machine clear, including the hot-air outlet.
Before operating the ice maker, make sure the drain plug is firmly inserted. Also check that the water tank, water filter, and ice basket are installed correctly.
The appliance is intended for household use. It should be connected directly to a properly installed grounded wall outlet. The manual states that an extension cord or relocatable power tap should not be used.
Do not operate the appliance if the power cord or plug is damaged, or if the appliance has been dropped or damaged in another way.
Understand the Ice Basket Full Function
The CB24M-B uses an Ice Basket Full indicator. When the ice basket is full, the machine stops making ice. The manual states that it resumes automatically within 30 minutes. Remove ice cubes promptly; when enough water is available, the unit may restart making ice immediately after ice is removed.
This function is separate from the Add Water indicator and should not be confused with a water-supply issue.
If the machine’s ice-making cycle appears normal but no ice is being formed, the manual lists several items to check:
- Room temperature and water temperature;
- Whether the room temperature is above 90°F / 32°C;
- Whether the water is warm;
- Whether the drain is restricted;
- Whether there is standing water in the water tank.
The manual recommends using chilled or cold water and keeping the appliance in a cool place for the best results.
Follow the Approved Cleaning Instructions
Regular cleaning is part of the CB24M-B maintenance instructions.
Before cleaning, turn the appliance off and unplug it. The manual also states that users must not immerse any part of the appliance in water or another liquid.
For regular cleaning, remove the ice basket and water filter. Rinse the ice basket and water filter with diluted detergent and water. Clean the water tank with a soft cloth moistened with water. Clean the exterior with a soft cloth dampened with soapy water, then dry it with a soft cloth.
The manual recommends cleaning the ice basket and water tank once a week to remove dirt and fibers.
Do not use solvents or chemicals to clean the appliance. Do not use mechanical devices to defrost, force-clean, or remove frozen parts.
Use the Self-Cleaning Function as Directed
The CB24M-B manual recommends self-cleaning at least once every one to two weeks.
To start a self-cleaning cycle, fill the tank with water below the MAX line. Press the CLEAN button. The manual describes this as a 10-minute self-cleaning cycle. When complete, the appliance turns off. Open the drain cap and allow the water to drain into a sink.
For scale or mineral buildup, the manual provides a separate deep-cleaning procedure:
- Fill the tank with water below the MAX line.
- Add distilled white vinegar or a citric-acid descaling agent.
- Leave the mixture for 12 hours.
- Press CLEAN to start a self-cleaning cycle.
- Repeat for three cleaning cycles.
- Drain the mixture.
- Run three further cleaning cycles with fresh water for rinsing.
Use only the cleaning methods described by the manual. The manual does not authorize unapproved solvents, internal lubrication, forced disassembly, or repairs performed by the user.
Do Not Disassemble the Ice Maker
The CB24M-B manual states that there are no user-serviceable parts inside the appliance.
Do not disassemble, repair, modify, or replace any part of the ice maker yourself. All service should be performed by qualified personnel only. The warranty section also states that unauthorized repairs, tampering, modification, and partial or complete disassembly can affect warranty coverage.
If you are asking why your nugget ice maker is squealing, do not attempt to solve the issue by removing panels, applying oil, accessing internal components, or forcing parts to move. These actions are not included in the CB24M-B user instructions.
When to Contact Customer Support
The troubleshooting guide states that users should contact customer support if problems persist.
Contact support if the issue continues after you have followed the approved setup, water, filter, cleaning, and transport instructions. The manual also directs users to contact support for water leakage.
Have your order ID ready before contacting customer support.
