Steps to Verify Issue:

CAUTION:
Do not to disconnect the drain tube from the drain trough.
Do not to put anything down the tube such as a brush as it may pierce the tube.

  1. Turn off the refrigerator either at the Unit On/Off button or turn the control dial down past 1 to OFF.
  2. Remove the crisper glass shelf, then the crisper drawer. Water or ice may collect behind the drawer.

  1. If there is ice on the floor of the refrigerator section, make sure the refrigerator dial control is set correctly to 38°F or 5 on a dial control. See Temperature Settings.
  2. Remove ice by defrosting unit or use a steamer to melt.
  3. Remove the two screws holding the kickplate to remove the kickplate at the bottom of the unit.

  1. On 601, 501, and 201 models, also remove the lower grille by removing the screws on right and left corners and then pull the bottom of the grille out and up to release it.

  1. Mix one quart of warm water with two caps full of bleach and a few drops of dish detergent to make a solution.
  2. If there is standing water in the trough that runs across the back wall, remove the water with a turkey baster, sponge, or towel.
  3. The drain trough extending across the back of the refrigerator is now visible. Use the turkey baster or similar to squirt or pour the bleach solution down the drain until it no longer overflows into the refrigerator and drains into the pan below the unit.

  1. Remove the drain pan when done, and clean it out since solution sitting in the pan could damage the plastic. See Sub-Zero Drain Pan Removal.

All Models Except 601, 501 601, 501 Models

  1. Install the kickplate and screws.
