What's Happening
The dishwasher detected more water than expected, usually from a drainage problem. Common causes include a clogged drain hose, blocked filter, missing garbage disposal knockout plug, or using regular dish soap instead of dishwasher detergent. On some models this displays as 0C or OE.
How to Fix It
Inspect the drain hose for kinks. Clean the filter and sump area. If connected to a disposal, verify the knockout plug was removed. Switch to proper dishwasher detergent. Unplug for 5 minutes, then run an empty Normal cycle.
