Dishwasher displays E22; water may remain dirty and filters may clog quickly.

Safety first: Turn off power before reaching into the sump area.

• Thoroughly clean filters: Remove the coarse and fine filters and wash them under hot running water with a soft brush.
• Inspect sump: Shine a light into the sump and remove any visible debris, such as bones, seeds, or glass.
• Check drain hose height and routing: Ensure the drain hose is installed at the correct height and without sags that can trap dirty water.
• Run a hot cleaning cycle: Use a dishwasher cleaner to remove grease and biofilm from internal surfaces.
• Review loading habits: Scrape excess food from dishes before loading to reduce future blockages.
