What PU Means
On Frigidaire dehumidifiers with a built-in pump, Frigidaire lists PU as a failure to pump out the bucket in the allotted time.
Common Causes of PU
- Kinked or blocked pump hose
- Frozen hose in a cold location
- Clogged pump pickup
- Failed pump
🔧 One Safe Check You Can Try
Turn the unit off and unplug it before handling water. Then follow Frigidaire's steps: verify the pump drain hose connection, check the hose for blockages, kinks or freezing, empty the water bucket and inspect the pickup, then plug the unit back in and restart. If PU returns with a clear hose, book service.
⚠ Why You Shouldn't Go Further Than That
- Owner checks cover the hose, bucket and pickup. Replacing the pump itself requires opening the housing near live wiring.
- Damage caused during a repair attempt may not be covered by your warranty — check your warranty terms first.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
