How to Fix / Troubleshooting
Safety first: Unplug the dishwasher and close the water tap.
- Check salt level: Ensure the salt reservoir is filled and cap is properly closed.
- Access regeneration valve: The valve is usually mounted on or near the water softener/heat exchanger on the side of the machine. Remove the side panel to locate it.
- Inspect connector: Ensure the valve connector is firmly attached and free of corrosion.
- Advanced test: With the appliance unplugged, measure the coil resistance of the valve. An open circuit indicates a faulty valve.
- Replace if faulty: Replace the regeneration valve with a compatible Balay part. If E19 persists, the control board may need repair.
