How to Fix / Troubleshooting
Safety first: Disconnect power before opening the control panel.
- Hard reset: Unplug the unit for at least 10 minutes to allow capacitors to discharge. Plug back in and test.
- Inspect control connections: Remove the front or top panel to access the control board and display board. Reseat all ribbon cables and harness connectors.
- Check for burn marks: Look for obvious damage on the PCB such as burnt components or discoloration. If present, the board must be replaced.
- Surge protection: If the error occurred after a power outage or surge, consider using a surge protector once the board is replaced.
- Replace control board: If E8 persists after reseating connectors, replace the main control PCB with the correct SPT part number. Transfer any wiring one connector at a time to avoid miswiring.
