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.
