Dishwasher displays E14; wash arms do not rotate and cleaning is poor

Safety first: Turn off power and allow the unit to cool before removing wash arms.

• 1. Remove and clean wash arms: Detach upper and lower spray arms. Rinse under running water and use a toothpick or small brush to clear blocked jets.
• 2. Check for obstructions: Inspect the tank for items protruding into the path of the arms, such as tall utensils or racks installed incorrectly.
• 3. Clean sump and filters: Remove and clean all filters and check the circulation pump inlet for debris that could reduce pressure.
• 4. Test pump performance: Run a cycle with racks empty and observe spray arm rotation through the door (if safe) or by briefly opening mid-cycle. Weak or no rotation suggests pump or impeller wear.
• 5. Electrical check: Verify correct supply voltage to the wash pump during operation.
• When to call a technician: If the pump impeller is worn or the motor is weak, replacement of the wash pump assembly is required.
