TLDR
On your LXe SERIES DISHWASHERS unit, if the machine fills too high or leaks from the door, it typically indicates either improper leveling or a malfunctioning fill solenoid valve. Unlevel installation compromises the door seal and drainage, while a leaking solenoid causes continuous water intake even when not required. Addressing these issues promptly is crucial to prevent water damage and ensure efficient operation.
Technical Details
Repair Steps:
- Check Machine Leveling: Visually inspect the dishwasher’s stance. Use a spirit level (bubble level) on both the front-to-back and side-to-side planes of the top rim of the machine or its frame. Adjust the machine’s leveling feet (typically adjustable threaded feet at each corner) using an appropriate wrench. Ensure all feet are firmly in contact with the floor and the machine is stable. The machine should be level for proper door sealing and drainage. Refer to the Hobart LXe installation manual for precise leveling instructions.
- Inspect for Fill Solenoid Valve Leakage: Locate the main power switch for the dishwasher and turn it OFF. Observe the machine’s interior for a few minutes. If water continues to flow into the machine despite the power being off, the fill solenoid valve is likely stuck open or leaking internally. A leaking fill valve will cause the machine to overfill or continuously dribble water, leading to potential leaks from the door or overflow.
- Contact Hobart Service: If you confirm the fill solenoid valve is leaking, do not attempt to repair it yourself unless you are a qualified technician. A leaking solenoid valve requires replacement, which involves working with water and electrical components. Contact your local authorized Hobart Service Office immediately to schedule a service call for diagnosis and replacement of the defective fill solenoid valve. Provide them with the model and serial number of your LXe unit.
- Check Door Gasket/Seal: While not explicitly mentioned as a cause in the original description, door leaks are a symptom. A compromised door gasket can contribute even if the machine is level. Inspect the door gasket (seal) around the perimeter of the door opening for cracks, tears, hardening, or debris. Clean the gasket thoroughly. If it’s damaged or brittle, it may need replacement by a service technician.
- Verify Drain Operation: Ensure the drain hose is properly installed and free of kinks or obstructions. Verify the drain system (pump, air gap if applicable) is functioning correctly and evacuating water efficiently. Slow draining can sometimes mimic overfilling issues.
Common Questions:
Q: Why is proper leveling so important for my Hobart LXe dishwasher?
A: Proper leveling ensures the dishwasher’s door seals correctly, preventing water leaks during operation. It also allows for efficient draining and prevents water from pooling in the wash chamber, which can lead to hygiene issues or inefficient washing.
Q: What is a fill solenoid valve and why would it leak?
A: The fill solenoid valve is an electronically controlled valve that regulates the flow of water into the dishwasher. It leaks when internal components (like the diaphragm or piston) wear out or become obstructed by scale/debris, preventing it from closing completely, thus allowing water to continuously enter the machine.
Q: Can I continue to use my Hobart LXe if it’s overfilling or leaking?
A: No, it is strongly advised to power off the machine and discontinue use immediately if it’s overfilling or leaking. Continued operation can lead to severe water damage to your kitchen, potential electrical hazards, and further damage to the dishwasher’s components. Contact a qualified technician promptly.
