TLDR
On your HOBART LXe SERIES DISHWASHERS unit, the BOOSTER LEVEL SENSOR error indicates the booster pressure switch is detecting an out-of-range condition, either open or short, preventing operation. This usually points to a faulty sensor, wiring issues, or a malfunctioning pressure switch itself. Immediate inspection and replacement of the defective component are required to restore machine functionality.
Technical Details
Repair Steps:
- Safety First: Disconnect Power. Always begin by disconnecting the HOBART LXe SERIES DISHWASHERS from its main electrical supply to prevent injury during troubleshooting.
- Inspect Wiring and Connections. Locate the booster level sensor and its associated pressure switch. Carefully examine all wiring leading to these components for any signs of damage, fraying, corrosion, or loose connections. Secure or repair as necessary.
- Test Booster Pressure Switch. Using a multimeter, test the booster pressure switch for proper continuity and resistance. Consult your Hobart LXe service manual for expected values. Confirm the switch is not stuck in an open or short circuit condition.
- Verify Water Levels and Fill System. Ensure that the booster heater is receiving the correct water fill and maintaining the appropriate water level. Issues with water supply or fill valves could indirectly affect the pressure switch readings.
- Replace Faulty Components. If the wiring is intact and connections are secure, but the pressure switch or sensor tests faulty, replace the defective component with a genuine OEM Hobart part.
- Reset and Test Operation. After replacing any parts, restore power to the dishwasher. Follow any specific Hobart procedures to clear the error code. Run a full cycle to confirm the error no longer appears and the machine operates correctly.
