Water Leaking from Underneath a Sub-Zero


  • Why is water leaking from underneath a Sub-Zero?
  • Why would water leak from the bottom of a Sub-Zero?
  • What would leak water below a Sub-Zero?

Steps to Verify Issue:

  1. If the amount of water is greater than a pint, it is likely from the water valve on the product or the home plumbing connections to the unit.
  2. Find the water supply shut-off valve and turn the water supply off. See also, Water Line Shut-Off Valve Location.
  3. Remove the kickplate.
  4. Find the home water supply connection to the unit.
  5. If the water is leaking from the home plumbing connections, contact a local plumber.
  6. If water leaks from the water valve on the product, the water valve may need replacement.
  7. If water leaks from the drain pan area, the pan may be missing, cracked, or broken. Replace the Drain Pan if needed.
  8. If water is overflowing from the drain pan, verify it is properly installed and level.
  9. If there is a standing puddle, solid stream, or water flow, it may originate from inside the refrigerator or freezer section. See Water Leaking from Sub-Zero for suggestions.
  10. If there is water on the door, door hinge, or door gasket, the drain tube may be clogged. See Water Leaking from Sub-Zero for suggestions.
