WP21001872 – Genuine OEM Whirlpool Washer Drain Hose

The WP21001872 Genuine OEM Whirlpool Washer Drain Hose is a factory‑original replacement drain hose engineered for Whirlpool washing machines and compatible appliances across several Whirlpool‑owned brands. This essential part safely carries wastewater from your washer’s drain pump to your household drain, ensuring complete and efficient draining during the wash and spin cycles. Sourced directly from Whirlpool, this hose meets strict manufacturer standards for performance and durability. 

Available from Appliance Kingdom, a trusted Canadian appliance parts supplier based in Edmonton, AB, this Genuine OEM washer drain hose is in stock and ships fast Canada‑wide for homeowners, landlords, and professional appliance repair technicians across Canada.

Function & Importance in Your Washing Machine

In top‑load and many front‑load washing machines, the drain hose connects the drain pump to your home’s drain system. During the drain cycle, this hose carries used wash water out of the washer and into the standpipe, laundry tub, or household drain line. 

A properly functioning drain hose is critical for:

  • Efficient draining after wash and rinse cycles

  • Preventing water backflow or leaks inside your laundry space

  • Maintaining proper wash cycle timing and performance

Using a Genuine OEM Whirlpool hose ensures that the part’s length, bends, and connection ends exactly match Whirlpool’s original design, supporting reliable drainage performance and long‑lasting operation. 

Common Symptoms Indicating Replacement

If your washer’s drain hose is cracked, kinked, brittle, or incorrectly routed, you may experience:

  • Water leaking onto the floor during or after drain cycles

  • Washer not draining fully or cycling repeatedly

  • Slow draining or partial water retention in the tub

  • Visible wear, splits, or soft/brittle hose material

In many cases, replacing a worn or damaged drain hose like the WP21001872 will restore proper draining performance and eliminate leaks, returning your washer to normal operation.
