    • Make sure the water line is properly connected to the dishwasher.
    • Check that the water supply valve is open for proper operation.
    • Verify that your household water pressure is above 20 psi.
    • Inspect the water line for any kinks or bends that may obstruct water flow or cause low pressure. Replace and secure damaged water lines according to local codes.
  3. Address Drainage Issues: If you encounter an OE error code, it suggests a drainage problem. To tackle this, perform the following:
    • Examine the drain hose for kinks or blockages.
    • Clear any buildup or obstructions, especially if you have a garbage disposal.
    • Ensure the drain connection on the garbage disposal is clear of any obstructions.
    • Install the drain hose to the garbage disposal, creating a tight seal.
    • Confirm that the dishwasher is not fully drained, as the overfill protection system may trigger an E1 error code in case of overfilling.
  4. Testing the Heating Element: To verify whether the heating element is faulty, follow these steps:
    • Unhook the water supply and disconnect power by turning off the breaker.
    • Access the heating element and test for continuity. If there is no continuity, the element is faulty and requires replacement.
  5. Replacing the Heating Element: If the heating element needs replacement, follow these instructions:
    • Undo the bolt in the middle to remove the old element.
    • Attach the new heating element, ensuring you remove the center nuts from the bolt before connecting the ground wire.
    • Optionally, consider disassembling the sump for easier installation and removal of the heating element.
  6. Water Test and Maintenance: After completing the repair, conduct a water test to check for any leaks by fully submerging the heating element. Applying a small amount of dish soap around the gasket may help with lubrication.
  7. Final Checks: Before every load, ensure the dishwasher door is properly closed, the gasket is making a seal, and there are no obstructions hindering proper closure. Additionally, unplug the unit and let it dry completely for up to 48 hours to reset the flow to its default setting. Proper loading of the dishwasher is essential for optimal performance.
