Whirlpool 88174303, 3/4 HP Garbage Disposal Review
The Whirlpool 88174303 is the largest disposal from this brand covered so far, a genuine 3/4 HP unit sold as a genuine OEM replacement for the earlier GC5000XEA model. Unlike the smaller Whirlpool units already reviewed here, this one is listed with Whirlpool Corporation itself as the manufacturer of record, rather than a third-party licensed manufacturer.
This is also the first Whirlpool disposal built around an induction motor rather than the RPM specs quoted for the smaller models, and it pairs that motor with an ABS polymer grinding chamber. Both are genuine, specific design choices worth understanding clearly before you decide if this is the right step up from a 1/2 HP disposal.
This review covers what the Whirlpool 88174303 actually delivers at 3/4 HP, what an induction motor means for daily use compared to the instant-torque motors covered on other brands, and how it stacks up against other 3/4 HP disposals already reviewed on this site.

Whirlpool 88174303, 3/4 HP Garbage Disposal Key Features
3/4 HP Induction Motor at 1725 RPM
The 88174303 runs a 3/4 HP induction motor rated at 1725 RPM. Worth understanding clearly: an induction motor takes a moment to reach full operating speed, unlike the permanent-magnet motors used on several other brands covered on this site, which hit full torque the instant they’re switched on. That’s not a defect, induction motors are a long-proven, reliable design used across countless appliances, but it’s a genuine mechanical difference worth knowing if you’re comparing this unit against an instant-torque competitor at the same horsepower.
At 3/4 HP, this is a genuine step up in grinding capacity from the 1/2 HP Whirlpool models already covered on this site, built for a household that regularly puts more volume and tougher waste through the disposal.
ABS Polymer Grinding Chamber
The grinding chamber is built from ABS polymer, a durable plastic that won’t corrode the way an exposed metal chamber can over years of use. Whirlpool’s listing doesn’t specify the material of the internal grinding wheel or impellers on this particular part number, so it’s worth reaching out to Whirlpool directly if the exact composition of every internal grinding component factors into your buying decision.
Continuous Feed Operation
Like the rest of the Whirlpool lineup, the 88174303 runs on continuous feed operation, switch it on, keep feeding waste through with the water running, and skip the pause-and-check-for-clogs routine that batch-feed disposals require. It’s the standard operating style most households already expect.
Genuine OEM Whirlpool Part
This listing is explicitly marketed as a Genuine OEM Whirlpool part, replacing the earlier GC5000XEA model. Whirlpool’s own messaging on this listing points to over 100 years of appliance manufacturing experience behind the part, and being listed with Whirlpool directly as manufacturer, rather than a third-party licensed manufacturer as seen on some of the smaller Whirlpool models covered on this site, is a detail worth knowing if buying direct from the brand matters to you.
Installation and What’s Included
The listing confirms the included component is the food disposer unit itself. At 16.37 lbs, this is a notably heavier unit than the smaller 1/2 HP and 1/3 HP Whirlpool models already reviewed here, worth factoring into your installation plan, particularly if you’re doing the swap yourself without help supporting the unit during mounting.
Maintenance
As with any disposal, avoid chemical or lye-based drain cleaners entirely, since that kind of corrosion damage typically isn’t covered under warranty regardless of brand. Run cold water while grinding to keep grease and fats solid enough to flush cleanly through the trap rather than coating the chamber.
Daily Use Experience
For a household that regularly grinds through heavier or more frequent waste than a 1/2 HP disposal comfortably handles, larger bones, thicker vegetable trim, a full sink after a big meal, the 88174303’s 3/4 HP induction motor is built for that added volume. The tradeoff for the induction design is a brief ramp-up to full speed rather than instant torque, a small difference in feel that’s worth knowing about rather than being surprised by on day one.
Warranty
Whirlpool backs the 88174303 with a 1-year limited warranty, stated directly in the product’s own listing. In line with the rest of the Whirlpool lineup covered on this site, that’s shorter than the 5-year and longer terms offered by several competing 3/4 HP disposals from other brands, a real factor to weigh against the Whirlpool name and the genuine OEM sourcing behind this particular part.

Conclusion
The Whirlpool 88174303 brings genuine OEM sourcing and a real 3/4 HP step up to the brand’s disposal lineup, backed by an ABS polymer grinding chamber and the same continuous feed simplicity found across Whirlpool’s smaller models. The induction motor is a proven, reliable design, even if it lacks the instant torque of the permanent-magnet motors used by some competitors.
Where it falls short of several other 3/4 HP disposals covered on this site is warranty length, 1 year against terms that run five years or longer elsewhere. If direct Whirlpool sourcing and brand trust matter more to your decision than the longest possible warranty number, the Whirlpool 88174303 is a solid pick for a household that has outgrown a 1/2 HP disposal.
