TLDR
On your HOBART LXn/LXGn SERIES DISHWASHERS unit, error code 006 indicates an overtemperature condition in the wash tank, exceeding 239°F (115°C). Initially, press and hold the power button for 5 seconds to clear the error, which will drain and power off the machine. If the high temperature persists after restarting, this points to a critical issue with the heating system or temperature sensor requiring immediate professional diagnosis to prevent damage or safety risks.
Technical Details
Repair Steps:
- Verify Initial Reset and Observe Machine Behavior: The machine’s built-in instruction is to press and hold the power button for 5 seconds. Do this exactly. The dishwasher should drain and power off. Allow the machine to cool completely (at least 30-60 minutes). Attempt to power on and run a short cycle. If the error immediately reappears, a deeper issue is present.
- Inspect Water Level and Fill Valve Functionality: An insufficient water level in the wash tank can cause heating elements to overheat the remaining water or even cycle dry, triggering an overtemperature error. Ensure the machine is filling correctly. Check for proper water pressure to the unit and verify that the fill valve opens and closes as expected. A faulty fill valve could lead to inadequate water volume.
- Check Wash Tank Temperature Sensor (RTD/Thermistor): The primary cause of an overtemperature error is often a faulty temperature sensor providing an inaccurate reading to the control board, or a sensor that has physically failed. Locate the wash tank temperature sensor (likely an RTD or thermistor). Disconnect it and test its resistance using a multimeter, comparing the reading to the manufacturer’s specifications at ambient temperature. A sensor that’s shorted or reading incorrectly could falsely indicate high temperature or fail to signal the control to stop heating.
- Examine Heating Elements and Associated Relays/Contactors: If the temperature sensor is functioning correctly, the issue is likely with the heating system itself. Power off and lockout/tagout the machine. Access the wash tank heating elements. Visually inspect them for signs of damage, arcing, or corrosion. Use a multimeter to check for continuity across the element terminals and for any shorts to ground. Also, inspect the relays or contactors that control power to the heating elements. A “stuck closed” contactor or relay will continuously supply power to the elements, causing an uncontrolled temperature rise.
- Inspect Control Board (PCB): The control board manages all machine functions, including reading sensor inputs and controlling heating elements. If the sensor and heating components appear operational, the control board itself might be sending a constant “heat on” signal or misinterpreting the temperature sensor data. Look for any visible signs of damage, burnt components, or loose connections on the PCB. This requires advanced diagnostics and often necessitates replacement by a qualified technician.
- Contact Hobart Service for Advanced Diagnostics: If the error persists after performing these initial checks, or if you are uncomfortable performing electrical diagnostics, it is crucial to contact a certified Hobart service technician. Overtemperature conditions can be a safety hazard and indicate serious component failure that requires specialized tools and knowledge to diagnose and repair correctly.
Common Questions:
Q: What does Hobart LXn/LXGn Error 006 signify?
A: Error 006 indicates that the wash tank temperature has reached or exceeded 239°F (115°C), triggering a safety shutdown to prevent damage and ensure operational safety.
Q: What should I do immediately when I see Error 006?
A: Press and hold the power button for 5 seconds. This will clear the error, initiate a drain cycle, and power off the machine. Allow the unit to cool before attempting a restart.
Q: If the error persists after resetting, what’s the likely cause?
A: Persistent Error 006 suggests a fault with the wash tank temperature sensor, a continuously energized heating element (due to a stuck relay or contactor), or a malfunction in the main control board.
