Error Code Explained

What Does the Viking Defrost Drain Blocked Error Code Mean?

During each defrost cycle in a Viking No Frost freezer, meltwater from the evaporator coil flows through a drain tube to a drip pan below the unit where it evaporates. If the drain tube becomes blocked with food debris or ice, meltwater overflows into the freezer compartment and pools at the bottom or on shelves.

Root Causes

Common Causes of the Viking Defrost Drain Blocked Error Code

  • 1
    Food Debris Blockage
    Small food particles have accumulated in the drain tube over time and created a blockage.
  • 2
    Frozen Drain
    Ice has formed in the drain opening, preventing meltwater from flowing during defrost cycles.
