TLDR
On your HOBART LXn/LXGn SERIES DISHWASHERS unit, error code 057 indicates that the wash tank's water level is too low at the start of a cycle, prompting the machine to automatically refill. While the dishwasher will eventually reach the correct level and begin operation, this suggests an underlying issue with water supply, fill valve function, or level sensor accuracy. Prompt investigation is recommended to maintain optimal cycle times and performance.
Technical Details
Repair Steps:
- Check Water Supply and Pressure: Verify that the main water supply valve to the dishwasher is fully open and that adequate water pressure is reaching the unit. Inspect the external fill hose for kinks, blockages, or damage that could restrict water flow.
- Inspect and Clean Inlet Water Filter/Strainer: Turn off the water supply and power to the machine. Locate the inlet water strainer, typically found at the machine’s water inlet connection, and carefully remove any accumulated sediment or debris. A clogged strainer is a common cause of restricted water flow and slow filling.
- Evaluate Water Inlet Valve: With the power off, inspect the electrical connections to the water inlet valve for looseness, corrosion, or signs of damage. If the valve is not opening fully or appears to be sticking, it may be faulty and require replacement. While power is off, you can visually inspect for any obvious physical blockages near the valve entrance.
- Examine Water Level Sensor: Disconnect power to the unit. Access the water level sensor (which may be a pressure switch, float switch, or probe) in the wash tank area. Physically inspect the sensor and its associated tubing (for pressure switches) for scale buildup, food debris, or obstructions. Clean any contaminants thoroughly and ensure all electrical connections to the sensor are secure and free from corrosion.
- Verify Drain Valve Closure: Although less frequent for this specific error, ensure the drain valve is fully closing and sealing properly. A small leak from the drain valve could contribute to a persistently low starting water level, requiring the machine to fill for longer before beginning the wash cycle.
Common Questions:
Q: Why does my Hobart LXn/LXGn dishwasher still run even with Error 057?
A: Error 057 is an informational message indicating a low wash tank water level at the cycle start. The machine automatically pauses, refills to the correct level, and then proceeds with the cycle, ensuring proper operation once water is replenished.
Q: What are the main causes of a low wash tank water level on my LXn/LXGn?
A: Common causes include insufficient incoming water pressure, a partially closed main water supply valve, a clogged inlet water filter or screen, or a malfunctioning water inlet valve preventing full flow. A dirty or faulty water level sensor can also contribute.
Q: Is it safe to continue using my Hobart LXn/LXGn dishwasher with this error?
A: Yes, it is generally safe to continue using the machine, as it will self-correct by filling. However, the error indicates a delay in your wash cycles and potential efficiency loss. It’s advisable to address the underlying cause to prevent future operational delays and ensure optimal performance.
