Hobart LXn/LXGn - Error 032: Booster Water Level Fill Error

🛑 Critical / Stop Operation
Warning: The information provided here is for educational purposes only. Working with commercial kitchen equipment involves high voltage, gas, and high temperatures. We strongly recommend contacting a certified service technician for any repairs. We are not responsible for any damage or injuries resulting from DIY repair attempts. This information is provided 'as is' without any guarantees of completeness or accuracy.

TLDR

On your HOBART LXn/LXGn SERIES DISHWASHERS unit, error code 032 indicates that the booster water level failed to reach its set point within the allotted time. This typically points to an issue with the incoming water supply, low water pressure, or a malfunctioning fill solenoid valve. Promptly check these elements to restore machine operation.

Technical Details

Repair Steps:

  1. Verify Incoming Water Supply: Ensure the main water supply valve to the dishwasher is fully open and that there are no kinks or obstructions in the fill hose. A partially closed or completely shut-off service valve is a common oversight.
  2. Check Water Pressure: Use a pressure gauge to verify the incoming water pressure at the dishwasher’s supply connection. The pressure should be between 15 – 65 psi (103 – 448 kPa). Low water pressure can prevent the booster tank from filling adequately.
  3. Inspect Fill Solenoid Valve:
    • Power down and unplug the dishwasher for safety.
    • Locate the fill solenoid valve, typically found at the water inlet point.
    • Check for any debris or blockages in the valve’s internal screen filter. Clean if necessary.
    • With the machine powered back on and calling for water, use a multimeter to check for 24V AC or 120V AC (depending on the model variant) across the valve’s terminals. No voltage indicates a control board issue; voltage with no water flow indicates a faulty valve.
    • If the valve receives power but doesn’t open, the valve itself is likely defective and requires replacement.
  4. Examine Water Level Sensor/Probe:
    • After isolating power, access the booster tank.
    • Locate the water level sensor or probe within the tank.
    • Inspect for scale buildup, debris, or damage that could impede accurate level detection. Clean the probe thoroughly if scale is present.
    • Verify the wiring connections to the sensor are secure and free from corrosion.
  5. Test Control Board Output (Advanced): If all external water supply and valve checks are satisfactory, and the fill solenoid valve is not receiving power, the issue might lie with the control board. This typically requires a qualified technician with specialized diagnostic tools to test the output to the fill valve and verify board functionality.

Common Questions:

Q: Why does my Hobart dishwasher show error 032 even with the water supply on?

A: Even if the water supply is on, the error can occur due to insufficient water pressure, a kinked fill hose, a clogged fill valve screen, or a malfunctioning fill solenoid valve that isn’t allowing water into the booster tank.

Q: What is the normal water pressure range for a Hobart LXn/LXGn dishwasher?

A: For optimal operation and to prevent error 032, your Hobart LXn/LXGn series dishwasher requires incoming water pressure between 15 and 65 psi (103 – 448 kPa).

Q: Can I reset error 032 myself, or do I need a technician?

A: You can attempt to clear error 032 by pressing the ENTER button after checking the incoming water supply and pressure. However, if the error persists after these basic checks, a qualified technician should be contacted to diagnose potential issues with internal components like the fill valve or control board.

When to call a technician

For this error, we recommend calling a certified technician. Do not continue operation or attempt repair yourself.
