Possible Causes
Loose or damaged harness between main control and display, Failed user interface board, Defective main control PCB, Electrical noise or grounding issues
How to Fix / Troubleshooting
Safety first: Disconnect power before accessing control compartments.
- Inspect connections: Open the control panel and verify that all ribbon cables and harness connectors between the main control and display are fully seated and free of corrosion.
- Check for moisture: Look for signs of water intrusion in the control area. Dry thoroughly and correct any gasket or seal issues.
- Visual inspection of boards: Examine both the main control PCB and user interface for burned components, cracked solder joints, or swollen capacitors.
- Grounding and power quality: Confirm that the dishwasher is properly grounded and that supply voltage is stable and within Insinger specifications.
- Board replacement: If wiring is intact and E16 persists, replace the user interface board first (if separate). If the fault remains, replace the main control board.
