Dishwasher displays E5 and will not start or complete a cycle; may stop shortly after filling.

Safety first: Turn off power and water before accessing internal components.

• Clean sump and filters: Remove the lower spray arm, filter screen, and fine filter. Clean out food debris, grease, and foreign objects that may affect water level sensing.
• Inspect pressure hose: Locate the small rubber or plastic hose running from the sump/air chamber to the water level sensor. Check for kinks, blockages, or waterlogged sections. Detach and blow through it to clear obstructions.
• Check sensor connections: Ensure the electrical connector on the water level sensor is fully seated and free of corrosion.
• Replace level sensor if needed: If the hose is clear and wiring is intact but E5 persists, replace the water level sensor/pressure switch with a compatible Zline part.
• Reset and test: Reassemble, restore power and water, and run a test cycle to confirm normal operation.
