OEM vs Aftermarket Dishwasher Drain Pump for Frigidaire: Honest Comparison (A00126401)

Your Frigidaire FFID2426TD6A won't drain, and there's standing water at the bottom after every cycle. You've checked — the drain pump is shot. Now you're staring at two options: a $180–$240 OEM replacement from an authorized dealer, or a $90.99 aftermarket assembly from Heima. The price difference is real, but so is the anxiety about whether aftermarket will actually work.

I've installed both types hundreds of times. Let's break down what you're actually getting with each.

Quick Answer

For most home repairs, the aftermarket A00126401 delivers identical performance at less than half the OEM cost. It fits the same models (FGID2466QF7A, FFBD2407LW0B, and 100+ others), uses the same mounting points, and handles the same drainage demands. Save the OEM premium for commercial installations or warranty-required repairs.

Side-by-Side Comparison

When OEM Makes Sense

There are three situations where I'd tell you to spend the extra $100–$150 on OEM:

Your dishwasher is still under manufacturer warranty. Using aftermarket parts can void coverage on other components. If your FGID2468UF0A is only 18 months old, stick with OEM to preserve your remaining warranty.

You're repairing a rental property for tenant complaints. Some property management companies require OEM documentation for insurance purposes. It's annoying, but cheaper than a liability claim.

You need same-day pickup from a local dealer. If your dealer actually stocks the pump (rare) and you can't wait 1–2 days for shipping, the convenience premium might be worth it. But call first — most dealers special-order these anyway.

When Aftermarket Wins

For standard residential repairs, aftermarket crushes OEM on value. The A00126401 replaces the exact same part numbers (AP5690431, 154736201, 5304492415, PS8689824), which means Frigidaire, Electrolux, and Kenmore all used variations of the same pump design across dozens of models.

The motor windings are identical spec. The impeller diameter matches. The mounting bracket uses the same three-screw pattern. When you're dealing with a clogged or defective pump on a FFID2426TS2A that's five years old, you're not paying for innovation — you're paying for branding.

Here's what actually matters: will it drain properly and handle debris without failing? The aftermarket version uses the same permanent magnet motor design that OEM does, rated for the same GPM flow and thermal protection. I've never seen one fail prematurely due to quality issues. The common failures (clogs, debris damage, seal leaks) happen with both types because they're inherent to how dishwasher pumps work.

The one-year warranty also beats OEM's typical 90-day coverage. If something goes wrong, you're covered longer.

The Real Installation Differences (Spoiler: None)

Both pumps install identically on compatible Frigidaire, Electrolux, Kenmore, Gibson, Kelvinator, and Westinghouse models:

1. Disconnect power and water supply
2. Remove lower dish rack and spray arm
3. Take out the filter assembly and sump cover
4. Disconnect the drain hose and wiring harness
5. Remove three mounting screws securing the pump
6. Swap in the new assembly (aftermarket or OEM — same process)
7. Reconnect everything and test

Difficulty level is moderate either way. No special tools required beyond a Torx driver and needle-nose pliers.

Pro tip: If your dishwasher has an unpleasant odor even after installing a new pump, the old pump wasn't your only problem. Run a cleaning cycle with Affresh dishwasher cleaner to clear out biofilm buildup in the spray arms and filter housing. A new pump won't fix smell issues caused by residue elsewhere.

Our Verdict

Save your money. The aftermarket A00126401 delivers the same drainage performance, fits the same 100+ Frigidaire and Electrolux models, and costs less than half what OEM dealers charge. Unless you're under active warranty or need same-day dealer pickup, there's no practical reason to spend $180+ on a branded pump. Install the Heima version, pocket the savings, and move on with your life.

Frequently Asked Questions

Will the A00126401 fit my Kenmore dishwasher if it originally had part number 154736201?

Yes. The A00126401 directly replaces 154736201, AP5690431, 5304492415, and PS8689824. These are all cross-reference numbers for the same pump design used across Frigidaire-manufactured dishwashers sold under Kenmore, Gibson, Kelvinator, and Westinghouse brands. Check your model number against the compatibility list, but if your original pump had any of those part numbers stamped on it, this fits.

How long does a dishwasher drain pump typically last after replacement?

Expect 5–8 years with normal use, regardless of OEM or aftermarket. Pump lifespan depends more on water hardness, how often you pre-rinse dishes, and whether debris makes it past the filter. The most common failure isn't the motor dying — it's the impeller getting damaged by glass shards, toothpicks, or other objects that shouldn't be in the dishwasher. Run the disposal before starting your dishwasher to minimize drain clogs.

Can I install this myself or do I need a technician?

If you're comfortable disconnecting appliances and using a screwdriver, this is a DIY-friendly repair. The pump is accessible from inside the tub (no need to pull the entire dishwasher out), and you're just swapping a component. Budget 45–60 minutes for your first time. The difficulty is moderate because you're working in a confined space and need to disconnect hoses without flooding your floor. Lay down towels and have a shallow pan ready — there's always residual water in the sump area.
