Viking Dishwasher I20 Error: Drain fault
What Viking Dishwasher i20 Code Means i20 is a drain fault — water isn’t leaving the tub. Clean the drain filter first (solves 60% of cases), then check the drain hose for kinks. If connected to a garbage disposal, run the disposal first. If draining still fails, the drain pump likely needs replacement (from $200).
