OEM vs Aftermarket Frigidaire Drain Pump: Honest Comparison (137221600)

Your Frigidaire ATF6000ES0 won't drain, and you've traced the problem to the pump. Now you're staring at two price tags: $45–$85 for an aftermarket 137221600 drain pump, or $140+ for the OEM part from Frigidaire. The performance is essentially identical, but the price gap is massive.

I've installed both versions dozens of times across models like the ATF7000FS1 and ATFB6700FS0. Here's what actually matters.

Quick Answer

Unless your washer is under warranty or you're preparing to sell it, the aftermarket pump makes more sense for 90% of homeowners. You'll save $60–$95, get the same 1-2 year warranty, and experience identical drain performance. The OEM pump only wins if you need perfect cosmetic matching or instant dealer availability.

Side-by-Side Comparison

When OEM Makes Sense

There are three scenarios where I'd spend the extra $40–$95 for the OEM pump:

Your washer is still under manufacturer warranty. Using aftermarket parts can void coverage on related components. If your ATF6700FE2 is less than a year old, stick with OEM and file a warranty claim.

You're flipping the appliance or prepping for a home sale. Buyers and inspectors can spot aftermarket parts. If you're selling within six months, the OEM logo adds perceived value.

You need it installed today. Authorized Frigidaire service centers stock OEM pumps. If your washer is leaking and you've got three days of laundry backed up, paying $60 more for same-day availability beats waiting for shipping.

When Aftermarket Wins

For most homeowners repairing models like the ATF8000FS2 or ATFB6000FS0, aftermarket delivers identical results at half the cost. The pump motor, impeller, and outlet port are functionally the same—they move the same gallons per minute and handle the same detergent residue.

The installation notes warn you'll need to configure the replacement pump's outlet port direction to match your old pump. This sounds complicated but takes about 90 seconds—you're just rotating the outlet housing to align with your drain hose. You'll also reuse the old mounting bracket, which is held by two screws.

Here's the reality: both pumps fail at roughly the same rate after 5–7 years of use. The drain pump gets clogged with lint, hair ties, and detergent buildup regardless of the brand name stamped on the housing. When the impeller seizes or the motor burns out, it doesn't matter if you paid $50 or $150—you're replacing it again.

Our Verdict

Save the $60–$95 and buy aftermarket unless you're under warranty or need same-day installation. The Heima 137221600 fits 200+ Frigidaire, Electrolux, Kenmore, and Gibson models (including ATF6500GG1 and ATF7000FG1), drains just as reliably, and comes with the same 1-year warranty. Spend the savings on preventive maintenance—run a washer cleaner cycle monthly to extend your new pump's life.

Frequently Asked Questions

Will an aftermarket pump void my extended warranty?

It depends on your warranty provider. Manufacturer warranties (Frigidaire's standard 1-year) can be voided by aftermarket parts. Third-party extended warranties (like those from home warranty companies) typically don't care as long as the part meets OEM specifications. Read your warranty fine print or call the provider before ordering.

Do I need to reconfigure the pump outlet direction?

Yes, on most installations. The replacement pump ships with the outlet port in a neutral position. You'll rotate the outlet housing to match your old pump's angle—typically 90° or 180°—so it aligns with your existing drain hose. The pump housing has stops that click into place, making it impossible to install incorrectly.

What causes drain pumps to fail on Frigidaire washers?

The most common culprit is debris clogging the impeller—coins, bobby pins, and lint build up over years of use. The motor can also burn out from running dry if the water level sensor fails. On models like the ATF6700FS2 and ATF7000ES1, detergent residue hardens around the impeller shaft, causing the motor to overheat. Running a monthly washer cleaner cycle and checking pockets before washing dramatically extends pump life.
