Dishwasher displays E20; circulation pump may run dry or cavitate, and water level may appear incorrect.

Safety first: Disconnect power before removing filters or accessing the sump.

• Clean filters thoroughly: Remove the Dacor filter assembly and wash under running water. Ensure all mesh sections are clear.
• Inspect sump area: Look into the sump for food, glass, or foreign objects that could block water flow to the circulation pump.
• Check sump seal and housing: From underneath, inspect the sump for cracks or leaks that could allow air into the system.
• Prime the system: After cleaning, pour a liter of water into the sump before starting a cycle to help prime the pump.
• Replace sump assembly if damaged: If the sump is cracked or warped, install a new Dacor sump assembly to restore proper circulation.
