Possible Causes
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker. Use anti‑static precautions when handling electronic boards.
Steps:
- Inspect control compartment: Remove the front or top panel to access the main control board. Look for signs of moisture, corrosion, or burnt components.
- Check all connectors: Gently reseat all harness connectors to the control board, ensuring they are fully engaged and latched.
- Verify supply voltage: With a multimeter (and power restored), confirm that line voltage to the machine is within Manitowoc’s specified range and that neutral/ground connections are solid.
- Dry moisture: If condensation or water has dripped onto the board, correct the source of moisture (leaks, poor ventilation) and allow the area to dry completely before restarting.
Replacement: If E10 persists after verifying wiring and voltage, replace the main control board. Programming or configuration may be required; consult the service manual or a Manitowoc technician.
