Scotsman Ice Machine Troubleshooting Guide

1. Scotsman Ice Machine Is Not Producing Enough Ice

Many ice production issues stem from the environment around your ice machine. Examine the exterior and interior temperature, floor level, and machine cleanliness to troubleshoot your machine when it's not producing enough ice. If you try all these troubleshooting steps and your ice machine is still experiencing low production, call a technician and schedule repairs.

• Check the room temperature: Maximum ice production for each machine is partially calculated based on the room temperature where the unit operates. If your location exceeds 70 degrees Fahrenheit, the machine will not produce the maximum amount of ice.
• Check the water temperature: The recommended water temperature for ice to form properly is 48-50 degrees Fahrenheit. If the water used to make the ice is too warm, the ice will not freeze well.
• Level the machine: Ensure that the machine sits balanced and level on the floor or countertop.
• Deep clean the machine: Grime, frost, and debris buildup could cause low ice production, so make sure you regularly deep clean your ice machine. 
• Check the waterline and water regulator valve: Call a technician to examine your machine if you believe the issue is related to the waterline or water regulator valve.

Tip: Any cause listed above also applies to low ice storage in compatible bins.

2. Scotsman Ice Machine is Leaking

External and internal leaks point to significant issues with your ice machine. While leaks inside the machine should be handled by a certified technician, it's possible to troubleshoot leaks outside your machine yourself. Perform the following steps to find the source of the problem.

• Turn off your machine before inspecting: Avoid any potential accidents or electrical injury by unplugging your machine before looking for the source of the leak. This precaution may also prevent the leak from expanding.
• Inspect the machine to determine the source: If the leak originates from a plumbing issue, you may need to call a technician or a plumber.
• Check the shutoff valve: If the leak stems from the water shutoff valve, contain the leak to avoid water damage and call a plumber to rectify the problem.
• Look for drain obstructions: Check the drains and clear any obstructions.
• Inspect the water line: Similar to water shutoff valve malfunctions, a cracked or loose water line requires the help of a plumber to return your machine to normal function.
• Deep clean the machine: Once repairs are made, deep clean your machine to prevent other buildup issues.
