E17 appears; dishwasher may stop during drain or at program end

Safety first: Disconnect power before working inside the tub or base.

• Clean sump and filters: Remove all filters and thoroughly clean the sump area. Ensure no food debris is blocking the sensor opening.
• Locate sensor: On some Rosières models, a water presence or optical sensor is fitted in the sump wall. Clean its surface gently.
• Check wiring: From the underside, verify that the sensor connector is secure and wires are intact.
• Test cycle: Reassemble and run a rinse program to see if E17 reoccurs.
• Replace sensor if needed: If the error persists and drainage is physically normal, replace the water presence sensor.
