Dehumidifier shows P1 and stops dehumidifying, water tank may be empty

Safety: Always unplug before reaching inside the tank compartment.

Steps:

• 1. Remove and reinstall tank: Pull out the water tank completely, then slide it back in firmly until it clicks or sits flush. Ensure no objects prevent full insertion.
• 2. Check float: Inspect the float inside the tank for free movement. Clean any slime or mineral deposits that may cause sticking.
• 3. Verify continuous drain setup: If using a hose, ensure it is connected to the correct drain outlet and not causing backflow into the tank area. The hose should slope downward with no kinks.
• 4. Inspect tank switch: Look for a small micro‑switch or sensor lever in the tank cavity. Press it gently to confirm it moves and clicks. Clean around it if obstructed.
• 5. Replace tank switch if faulty: If the switch does not change state when pressed (checked with a multimeter), replace the Beko tank presence switch assembly.
