E2 error appears shortly after power-on; machine does not heat and no steam or hot water is produced.

Safety first: Disconnect the appliance from mains and allow at least 30–45 minutes for internal components to cool.

Inspection steps:

• Access the thermoblock: Remove the top or side cover (depending on model). The thermoblock or boiler is usually an aluminum block with heating elements and a small sensor attached.
• Locate the NTC sensor: Look for a small probe or screw-in sensor with two thin wires leading to the main PCB. On many Gorenje units it is clipped or screwed into the thermoblock body.
• Check wiring: Inspect the sensor wires for cuts, burn marks, or loose connectors. Reseat the connector on the PCB and at the sensor.
• Test the sensor (for skilled users): Using a multimeter set to resistance, measure across the NTC leads (with the machine unplugged). A typical NTC will read between 5–100 kΩ at room temperature. An infinite reading indicates an open sensor; near 0 Ω suggests a shorted sensor.
• Replace if faulty: If readings are out of range or the sensor is physically damaged, replace it with a Gorenje-compatible NTC probe designed for your model. Apply a thin layer of thermal paste if specified and secure it firmly to the thermoblock.

Note: If a known-good sensor still results in E2, the control PCB may be defective and should be diagnosed by a professional.
