Water leaks in a commercial refrigerator can lead to serious issues if not addressed promptly. The first step is to locate the source of the leak. Often, leaks occur around drain lines or where ice has built up and started to melt.

Inspect all visible parts of the refrigerator for signs of water. Pay special attention to the area around drain lines. If you find ice near these areas, it could indicate that the drain line is blocked, causing water to overflow and leak out.

Clear Drains Regularly

Blocked drain lines are a common cause of water leakage in commercial refrigerators. To prevent this:

  1. Turn off your refrigerator.

  2. Locate your drain lines—often found at the bottom or back of the unit.

  3. Use a plumber’s snake or a long wire to gently clear any blockages.

  4. Pour warm (not hot) water down the drains to ensure they’re completely clear.

Regular maintenance like this keeps water flowing freely away from your unit, preventing leaks.

Defrost Evaporators

Frost accumulation on evaporator coils is another frequent issue that can lead to blocked drains and subsequent leaking. Defrosting should be part of regular maintenance:

  1. Switch off your refrigerator.

  2. Open doors and allow ice to melt naturally, or use a hairdryer on a low setting if needed.

  3. Never chip away at ice with sharp objects as this can damage components.

  4. Once defrosted, clean up any excess water immediately to avoid refreezing.

This process helps maintain optimal airflow and cooling efficiency.

Adjust Settings Carefully

Improper settings on your commercial refrigerator can contribute to unnecessary ice buildup:

  • Check that temperature settings align with manufacturer recommendations.

  • Ensure that doors seal properly when closed.

  • Verify that defrost cycle settings are correct for your specific model.

Adjustments here help prevent future issues with frost and leaking by maintaining consistent temperatures throughout the unit.
