How to Fix / Troubleshooting

Safety: Use only Electrolux-approved descaling agents. Unplug the machine before internal inspection.

Steps:

  • 1. Follow the manual exactly: Ensure you are starting the descaling program as described in the user manual, with the correct button sequence and solution concentration.
  • 2. Reset machine: Turn off the machine, unplug it for 10 minutes, then retry the descaling cycle.
  • 3. Check water path: Ensure the water tank is properly seated and any descaling intake tubes are not kinked or blocked.

Advanced:

  • 4. Verify flowmeter operation: If descaling stops immediately, the flowmeter may not be registering flow. Inspect and clean or replace the flowmeter.

Resolution: If E18 persists, a firmware or control board issue may be present and should be addressed by an authorized service center.
