Why Is My Subcold INTEGRA Freezing Up or Developing Ice?

Updated 29 September 2026

Some moisture or frost can occur inside a refrigerated appliance, but excessive ice build-up may affect cooling performance.

Common Causes of Ice Build-Up

Ice formation may be increased by:

  • Frequent door opening

  • Leaving the door open for long periods

  • The door not closing completely

  • An incorrectly positioned door seal

  • A very cold temperature setting

  • Warm or humid air entering the cabinet

Check the Door

Make sure:

  • No bottles or shelves are obstructing the door

  • The gasket sits evenly around the door

  • The appliance is level

  • The door closes tightly

Check the Temperature Setting

The INTEGRA can be adjusted between 3°C and 18°C.

If excessive ice develops, check whether the appliance is set much colder than required.

Defrosting the Appliance

If excessive ice is present, the manual recommends carrying out a manual defrost.

Before cleaning or defrosting:

  • Disconnect the appliance from the mains

  • Remove the contents

  • Allow the ice to melt naturally

  • Wipe away excess water using dry cloths or paper towels

The drip tray may overflow if a large amount of ice melts, so monitor the appliance during defrosting.

Do not use sharp tools, heaters or other equipment to accelerate the process, as this may damage the refrigeration system.

When to Contact Support

Contact Subcold Customer Service if:

  • Heavy ice quickly returns after defrosting

  • The door seal is damaged

  • The cooler cannot maintain the selected temperature

  • Water repeatedly appears underneath the appliance

  • An E1 or E3 error code is displayed
