Dehumidifier will not start and displays E1 on the control panel

Safety first: Unplug the dehumidifier from the mains before removing any covers. Do not work on the unit while it is connected to power.

Steps to check and fix:

• 1. Power reset: Unplug the unit for 5–10 minutes, then plug back in and try to start. If E1 returns immediately, continue.
• 2. Locate the ambient temperature sensor: On most Beko dehumidifiers, the room NTC sensor is clipped near the air intake grille or on the evaporator inlet area, connected by two thin wires to the main PCB.
• 3. Inspect wiring and connector: Remove the front or side panel as per the user manual. Check the small 2‑wire harness from the sensor to the control board. Look for broken wires, pinched cable, or loose/corroded plug. Reseat the connector firmly.
• 4. Test the sensor (if you have a multimeter): Disconnect the sensor from the board. Measure resistance across the two sensor leads. At room temperature (~20–25°C), an NTC sensor typically reads between 5–20 kΩ (exact value depends on model). If it reads open (infinite) or near 0 Ω, the sensor is faulty.
• 5. Replace the sensor if defective: Order a compatible Beko ambient NTC sensor using the model number of your dehumidifier. Clip the new sensor in the same location and route the wires as originally installed. Connect to the same PCB socket.
• 6. If sensor and wiring are good: If resistance is within normal range and wiring is intact, the fault may be on the main control PCB. In that case, replacement of the main PCB is usually required and is best done by a qualified technician.

Do not bypass or short the sensor permanently; this can cause improper operation and icing or overheating.
