    Why is my ITV IQ 135 working, but not making ice?
    • K
      Kimberly ToddAug 16, 2025
      If your ITV Ice Maker is working but not producing ice, consider these potential issues: * **Refrigerant Leak:** The system might be leaking refrigerant. Repair the leak and recharge the refrigerant. * **Faulty Compressor:** The compressor could be malfunctioning. Replace the compressor. * **Valve/Capillary Issues:** The expansion valve might be closed or damaged, or the capillary could be obstructed. Open or replace the valve (or capillary) and dehydrating filter. * **Moisture in Refrigeration System:** Water or humidity might have entered the system. Charge compressor oil, replace the capillary and dehydrator (use an anti-acid one), create a vacuum in the installation, slightly warm up all components and charge refrigerant.

    Why does my ITV Ice Maker work inconsistently?
    • D
      Daniel WebbAug 27, 2025
      If your ITV Ice Maker is working inconsistently, here are a couple of things to check: * **Low Water Pressure:** If the water pressure is lower than 0.7 BAR, especially when other taps are in use, for smaller units try regulating the water trough float. Larger machines might require installation of a mains pressure raising unit. * **Appropriate Water Pressure:** If the water pressure is within the range of 0.7 to 6.5 BAR, regulate the water level in the trough.

    Why is my ITV IQ 135 Ice Maker leaking water?
    • J
      Jonathon CuevasAug 30, 2025
      If you're experiencing water leaks in your ITV Ice Maker, here's what might be happening: * **Overflowing Trough:** Water from the trough might be overflowing into the ice bin because the buoy valve isn't closing properly. Adjust the water level, reduce the water pressure, and clean or replace the valve. * **Defective O-rings:** The o-rings in the lower bearing could be defective. Seal with silicone or replace them.

    Why is the compressor in my ITV IQ 135 working intermittently?
    • D
      Donald GrahamNov 18, 2025
      If the compressor in your ITV Ice Maker is working intermittently, the following could be the reasons: * **Dirty Condenser:** The condenser might be covered in dust or debris. You should clean the condenser. * **Obstructed Air Circulation:** Ensure there's enough space around the unit for proper airflow. Re-establish air circulation. * **Defective Condenser Fan:** The fan might not be working correctly. Check and replace the fan if necessary. * **Defective Fan Pressostat:** The fan pressostat may need adjustment or replacement. Check, replace, or adjust it. * **Defective Safety Pressostat:** The safety pressostat could be faulty. Check and replace it. * **Defective Compressor Start System:** There might be an issue with the compressor's starting mechanism. Check and replace it...

    What to do if the ice from my ITV IQ 135 Ice Maker is too wet?
    • E
      Erica ChaneyNov 20, 2025
      If your ITV Ice Maker is producing ice that is too wet, consider these factors: * **High Room Temperature:** If the room temperature is above 35ºC, relocate the unit to a cooler place. * **High Water Temperature:** If the water temperature is above 30ºC, ensure that the filter and inlet tube are away from heat sources. * **Poor Water Quality:** If the water quality is over 1500 ppm, lower the water trough and install a water purifier. * **Dirty Condenser:** If the condenser is dirty, clean it. * **Valve Issues:** If the pressure-controlled valve on the cooling water needs adjustment or is defective, adjust or replace the valve. * **Low Compressor Output:** If the compressor output is low, replace the compressor. * **Refrigerant Leak:** If there is a refrigerant leak, repair ...
