Quick answer
PU — Pump failed to empty the bucket within the allowed time
Model compatibility: Frigidaire reuses codes across series and model years, so PU may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
PU is a control-reported condition, not an automatic proof that one component has failed. Wiring, sensors, airflow, water, mechanical restrictions and the control itself can produce similar displays.
Pump failed to empty the bucket within the allowed time. Platform note: General Frigidaire dehumidifier / Gallery GHDD platform. Confirm the exact model family before applying a service procedure from another Frigidaire generation.
Signs
Symptoms you may notice
The appliance may show this behavior: code returns after a restart or at the same point in a cycle.
The appliance may show this behavior: water may remain in the tub, the cycle may stop before spin/end, or the code may return during a drain step.
The appliance may show this behavior: affected function may be disabled while other functions still operate.
The appliance may show this behavior: appliance may enter a protective state to prevent additional damage.
Why it happens
Possible causes
Diagnosis may need to consider kinked or blocked drain hose — that possibility is not a confirmed failed part.
Diagnosis may need to consider clogged pump or filter area — that possibility is not a confirmed failed part.
Diagnosis may need to consider failed drain pump — that possibility is not a confirmed failed part.
Diagnosis may need to consider water-level sensing issue — that possibility is not a confirmed failed part.
Diagnosis may need to consider control or wiring issue — that possibility is not a confirmed failed part.
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Inspect the drain hose for kinks, crushing, or an obvious blockage. Stay within normal owner access and stop if a safety warning appears.
Confirm the standpipe/drain installation has not changed. Stay within normal owner access and stop if a safety warning appears.
Remove only user-accessible debris or filters described in the owner manual. Stay within normal owner access and stop if a safety warning appears.
Run one drain/cancel cycle after correcting an obvious restriction. Stay within normal owner access and stop if a safety warning appears.
Do not bypass door or lid locks, open sealed refrigeration systems, service microwave high-voltage sections, or dismantle internal gas or induction power modules.
Important safety warning. Stop using the appliance for smoke, arcing, a burning-electrical smell, repeated breaker trips, uncontrolled heating, or water reaching electrical parts.

When to call a technician
If PU returns after the safe external checks, or the appliance shows a safety warning, professional diagnosis is appropriate. A technician should confirm the Frigidaire model and test the implicated system rather than replacing a part from the code description alone.
Seeing this code on your Frigidaire appliance?
Book a specialist visit for a clear estimate and approval before any repair.
Pump failed to empty the bucket within the allowed time That technical note still has to be confirmed against the exact model and control generation.
Record the code first. One controlled reset can be reasonable when there is no safety warning. Repeated resets are not a repair.
No. The code can point to a system while the failed item is wiring, a restriction, a sensor, or another connected component.
