Frigidaire Dishwasher Not Draining or Water Left in Tub? A00126401 Drain Pump – Fix No Drain Fast
Standing water in the bottom of your dishwasher after a cycle is almost always caused by a failed drain pump. In Frigidaire and Electrolux dishwashers, the A00126401 drain pump removes wastewater from the tub at the end of every wash and rinse cycle. When the pump motor burns out, the impeller jams with debris, or the housing develops a leak, water stays in the tub and the dishwasher may throw drain error codes. ⚡ Most common drain failure on Frigidaire-platform dishwashers. Part A00126401 is the genuine OEM drain pump assembly that restores full drainage immediately — OEM and XPart aftermarket options available.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Dishwasher powers on and wash cycle runs normally
- ✔ Drain hose is unkinked and not clogged at the sink connection
- ✔ Filter and sump area cleaned and confirmed clear of debris
- ✔ Garbage disposal knockout plug removed (if newly installed disposal)
- ✔ ONLY problem is water remaining in tub after cycle, no drain, loud noise during drain, or i20/i30/i40 error codes

Before replacing the pump, remove and clean the dishwasher filter and sump — a debris-jammed impeller is the most common cause of pump failure and cleaning it out first may restore drainage without a part replacement. If the motor is burnt out or the housing is cracked, the pump must be replaced.
⚙️ Installation
Skill Level: MODERATE — 30–45 minutes. Disconnect power and turn off the water supply before beginning. The drain pump is located at the bottom of the dishwasher tub — remove the lower spray arm, filter assembly, and sump cover to access it. Disconnect the wiring harness and drain hose, twist the pump counterclockwise to unlock it from the sump housing, and install the new A00126401 in reverse order. Run a short cycle and confirm full drainage before reinstalling the lower rack.
💡 Pro Tip
Frigidaire dishwasher drain pumps fail most often because debris bypasses the filter and jams the impeller — not because the motor itself has failed. Remove the filter and sump cover and check for glass shards, food debris, or grease buildup around the impeller before ordering a pump. A 10-minute cleaning job resolves roughly 30% of “not draining” calls on this platform. If the impeller spins freely and the motor still won’t run, then replace the pump.
