If your Necta Koro displays "set boiler," follow these steps to troubleshoot and fix the issue:

1. Check the Boiler Thermostat:
- If the thermostat has been triggered due to overheating or dry operation, reset it by pressing the central red button.

2. Ensure Water Supply:
- Verify that the machine is receiving water. If the water supply is blocked or not functioning, the boiler may not fill properly.

3. Inspect the Air Break System:
- The Air Break system controls water flow to the boiler. Ensure the float tank and micro switch are functioning correctly. If the micro switch is not signaling properly, it may cause an error.

4. Run Initialization (Initializare db):
- Perform a full initialization to reset any system errors. Use the machine’s navigation keys to access the settings and complete the initialization process.

5. Check the NTC Temperature Probe:
- The boiler temperature is controlled by an NTC probe. Ensure it is functioning correctly and within the expected resistance values.

6. Restart the Machine:
- After performing the checks and resets, restart the machine to see if the error is resolved.

If the issue persists, further diagnosis may be needed, such as checking wiring connections or replacing faulty components.

To resolve the drink selection issue on the Necta Koro ES coffee machine, follow these steps:

1. Open the top panel hatch to access the decaffeinated coffee option.
2. Wait for the “Decaffeinated” message to blink on the display.
3. Insert a dose of the desired ground blend.
4. Close the hatch.
5. Make a drink selection as usual.
6. Wait for the drink to finish dispensing and collect it.

Important: After dispensing, the machine automatically resets to standard configuration.

If no decaffeinated drink is selected after opening the hatch:
- The machine retains the “Decaffeinated” input.
- Manually reset it by pressing the “Cancel decaffeinated” button.

This will restore the standard drink selection configuration.
