Dishwasher runs but spray arms do not rotate properly; poor cleaning and E7 error displayed.

Safety first: Unplug the dishwasher and ensure it is cool and empty before working underneath.

• 1. Check spray arms: Remove upper and lower spray arms and clean out any blocked jets under running water. Ensure they spin freely when reinstalled.
• 2. Listen to the motor: Start a cycle and listen. A loud humming without water movement suggests a jammed or failed circulation pump.
• 3. Access circulation pump: Remove the lower front panel and, if necessary, tilt the dishwasher carefully. Locate the main wash motor/pump assembly attached to the sump.
• 4. Inspect impeller: If accessible, remove the pump cover and check for broken glass, seeds, or debris jamming the impeller. Remove obstructions carefully.
• 5. Wiring check: Inspect the motor wiring harness and capacitor (if fitted) for loose connections or burn marks.
• 6. Replacement: If the motor is seized, leaking, or shows signs of overheating, replace the complete circulation pump assembly.
• 7. Professional help: Because the circulation pump is central to operation and requires base access and sealing, many users should have a technician perform this repair.
