Dishwasher shows E7; unit may fill but not wash, or stops shortly after starting the wash phase.

Safety first: Turn off power and ensure the tub is drained before tilting or moving the dishwasher.

• 1. Listen for pump operation: Start a cycle and listen after filling. A loud hum without water spraying indicates a jammed or failed circulation pump.
• 2. Inspect filters and sump: Remove the lower rack and filters. Check the sump area for broken glass, bones, or plastic that could block the pump inlet.
• 3. Access the circulation pump: Lay the dishwasher on its back (with towels to catch water) and remove the bottom panel. Locate the Haier circulation pump attached to the sump.
• 4. Check impeller and rotation: Remove the pump or its cover and inspect the impeller for debris. Try turning the impeller by hand; it should move freely. If stiff or locked, the pump must be replaced.
• 5. Electrical tests: Measure motor winding resistance and check any external start capacitor. Replace the pump assembly if windings are open or the motor is shorted.

Warning: The circulation pump is water-exposed; ensure all seals and clamps are correctly refitted to prevent leaks.
