Dehumidifier displays P1 and will not start dehumidifying

Safety first: Turn the unit OFF and unplug it before removing any panels or buckets.

Steps to resolve P1:

• Empty the bucket: Slide out the internal water bucket (if your Whynter model has one). Carefully empty all water and rinse out any debris or slime.
• Check bucket seating: Reinstall the bucket firmly until it clicks or sits flush. Many Whynter dehumidifiers have a small switch that must be pressed by the bucket edge.
• Inspect the float: Inside the bucket, verify the plastic float moves freely up and down. Clean off mineral buildup or mold that may cause it to stick in the “full” position.
• Check the bucket switch: With the unit unplugged, locate the bucket/full switch near the bucket cavity. Make sure the actuator lever is not bent or broken. Gently press it by hand to confirm it moves freely.
• Test operation: Plug the unit back in and power it on. If P1 clears, monitor for normal operation. If the code returns immediately, the float switch or bucket switch may be faulty and require replacement.

When to stop: If you see damaged wiring, cracked plastic around the switch, or the switch feels loose inside the cabinet, stop and contact a qualified technician.
