Error Code: 1C Difficulty: Moderate

Problem: Filter clogged / Load or detergent issue

How to Fix 1C Error

CLEAN THE FILTERS. This code often indicates a clogged filter. Open the dishwasher and remove the lower rack. Twist and lift out the main filter assembly from the bottom of the tub.
WASH THE FILTERS. Separate the cylindrical micro-filter from the coarse filter plate. Wash both thoroughly under warm running water using a soft brush to remove food particles and grease.
REINSTALL AND TEST. Reassemble the filter components and lock them back into place in the dishwasher. Run a new cycle. If the code returns, use less detergent and ensure dishes are not blocking the spray arms.

If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
