How to Fix / Troubleshooting

Safety first: Unplug the dishwasher before accessing the side panel.

  • 1. Check salt and settings: Ensure the salt reservoir is filled and the hardness setting is correct. This will not clear E19 alone but prevents further issues.
  • 2. Access softener valve: On many Constructa models, the regeneration valve is mounted near the water softener on the side of the tub. Remove the side panel to locate it.
  • 3. Inspect wiring: Confirm the valve's electrical connector is secure and wires are intact.
  • 4. Listen for operation: During a regeneration phase (usually at the end of a cycle), you may hear the valve click. Lack of sound can indicate a failed coil.

When to call a technician: Replacement of the regeneration valve or softener assembly is a job for a professional due to the integrated hydraulic design.
