Essentials freezer shows E10 and the alarm may sound continuously.

Safety: Ensure the unit is plugged into a properly grounded outlet. For internal checks, unplug before handling wiring.

Steps to address E10:

• 1. Confirm actual temperature: Place a separate freezer thermometer inside and allow it to stabilize for several hours. Compare the reading to the set temperature.
• 2. Check door seal and usage: Make sure the door is closing fully and not being left ajar. Overloading the freezer or frequent door openings can trigger a high temperature alarm.
• 3. Inspect cabinet sensor: Access the cabinet NTC sensor (see E1 procedure). Ensure it is firmly attached to the liner and not hanging loose in air, which can cause inaccurate readings.
• 4. Test sensor resistance: If the actual temperature is normal but E10 persists, test the cabinet sensor with a multimeter. Replace the cabinet NTC temperature sensor if readings are unstable or out of range.
• 5. Reset alarm: Many Essentials models allow you to silence or reset the alarm via the control panel. After correcting the cause, press and hold the alarm or reset button as per the user manual.

Note: If the freezer is genuinely not reaching temperature, see the no-cool and poor-cooling fault entries below for further diagnosis.
