Dishwasher displays E4 and may stop filling; sometimes accompanied by water remaining in the tub or poor wash performance.

Safety first: Disconnect power and close the water supply valve before working inside the tub or under the unit.

• Clean filters: Remove the lower rack. Twist and lift out the coarse and fine filters from the bottom of the tub. Rinse thoroughly under warm water and remove food debris from the sump area.
• Check spray arms: Remove upper and lower spray arms. Rinse and clear any blocked jets using a toothpick or soft brush. Reinstall securely.
• Inspect circulation pump: Access the bottom of the dishwasher. Locate the Midea wash circulation pump attached to the sump. Check for foreign objects (glass, bones, labels) around the impeller by removing the pump cover if accessible.
• Test run: Reassemble and run a rinse cycle. Listen for a strong spray sound. If E4 persists and the pump hums but does not move water, the pump motor may be failing.
• Professional service: Replacing the circulation pump involves tipping the dishwasher, disconnecting hoses, and resealing the sump; if you are not experienced, contact a technician.
