Dishwasher displays E17; circulation may be weak and spray arms may not rotate properly.

Safety first: Disconnect power before removing internal components.

• Clean filters: Remove and thoroughly clean the coarse and fine filters in the bottom of the tub.
• Clean spray arms: Remove upper and lower spray arms. Rinse under running water and use a toothpick or small brush to clear each jet hole.
• Inspect pump inlet: Access the sump and check for debris at the circulation pump inlet screen. Remove any obstructions.
• Check impeller condition: From the bottom, access the circulation pump and inspect the impeller for broken blades or looseness on the shaft. Replace the pump assembly if worn.
• Verify electrical supply: Ensure the dishwasher is on a dedicated circuit and that voltage is within specification.
