How to Fix / Troubleshooting
Safety first: Unplug the machine before extended maintenance.
Deep descaling:
- Use correct descaler: Only use Gorenje-approved or manufacturer-recommended descaling solution. Avoid vinegar, which can damage seals.
- Repeat descaling: Run two full descaling cycles back-to-back, ensuring you follow the exact water and solution ratios in the manual.
- Flush thoroughly: After descaling, run at least 1–2 full tanks of fresh water through the hot water and coffee circuits to remove residue.
- Check flow meter: If the error persists, inspect and, if necessary, replace the flow meter, as incorrect pulse output can trigger E11.
Advanced: Some models require a service-level reset of the descaling counter via a hidden menu, which should be done by an authorized technician.
