Understanding the Problem
Brief explanation: The drain hose on a Kenmore 800-series washer carries wastewater from the washer's drain pump to the standpipe, laundry sink or drain. Over time the hose can crack, split, clog, kink, or loosen at the pump or standpipe connection — causing leaks, slow draining or a washer that won't drain at all. Diagnostic & repair steps: 1) Confirm model and buy the right hose: Locate your washer model tag (usually inside the door or on the back). The drain hose is often a model-specific shape/length but many owners use a universal replacement (3–8 ft, ~1.25–1.5 in ID). Buy a hose and at least two worm-gear clamps (stainless steel). 2) Tools & supplies: flathead & Phillips screwdrivers, pliers, utility knife (if cutting hose), bucket, towel, flashlight, replacement hose, clamps, zip-ties. 3) Safety first: Unplug the washer (disconnect power). Turn off the water supply and shut off water valves if you’ll be moving the washer or exposing the inlet. Keep towels and a bucket handy for residual water. 4) Drain residual water: Run a drain/spin or manually drain the tub into a bucket by tipping the washer back slightly (if safe) or removing the lower access panel and opening the pump port (if applicable). 5) Access the drain hose: Pull the washer away from the wall to reach the back. Follow the hose from the pump outlet to the standpipe or sink. 6) Remove the old hose: Loosen the clamp at the pump outlet (use screwdriver or pliers for spring clamp). Release the clamp at the standpipe/sink. Slide the old hose off and discard it. Inspect the pump spout/outlet for cracks, jagged edges or broken tabs. 7) Inspect and clear blockages: Before installing the new hose, look inside the old hose and the pump outlet for lint, small clothing, sediment or soap buildup. Use a flashlight and remove any obstruction with pliers. Check the standpipe, P-trap and sink for clogs. 8) Install the new hose at the pump: Slide the hose onto the pump outlet far enough to cover the barb/spigot (about 1/2"–1" depending on pump), and position a worm-gear clamp over the connection. Tighten the clamp securely but don't crush the hose. 9) Route & secure the hose properly: Route the hose up and over the washer tub rim (or to the designated clip). Ensure the high-loop or air gap is in place to prevent siphoning. Insert the hose into the standpipe or sink drain properly — do not push it too deep. Secure with a clamp or zip-tie to a stable anchor point on the washer to prevent it being pulled loose during spin. 10) Connect at the standpipe/sink: Use a clamp or the existing hookup to secure the hose at the drain. If using a laundry sink, make sure the hose isn't submerged — the end should sit above the flood level. 11) Test the repair: Plug the washer back in, run a short drain/spin or small wash cycle while watching for leaks at both connections and along the hose. Check for proper drain speed and listen for pump noise. Tighten clamps if needed. 12) If problems persist: If there's still no drain or slow drain after confirming the hose and connections are clear and secure, the drain pump impeller, pump motor, or an internal blockage (trap/P-trap/standpipe) may be faulty — test/replace the drain pump next. Safety note: Always disconnect power before working on the washer. If you need to access the pump from inside the cabinet or work under the machine, wear gloves and eye protection. If you’re unsure about the pump or electrical components, consult a professional.
Common Symptoms
Visible leak at the back of the washer, water on the laundry room floor during or after a cycle, slow draining or washer not draining, intermittent drain errors or loud gurgling from the drain hose.
Common Causes
- Cracked, split, or deteriorated drain hose
- Loose or missing hose clamp at the pump or standpipe
- Blockage inside the hose, standpipe or P-trap (lint, coins, small items)
- Kinked hose or improper routing causing restricted flow
- Damaged pump outlet or pump-to-hose connection (requiring pump replacement)

Helpful Repair Tip
Run one short drain-only cycle with the washer empty and watch the back connection area — a visible stream or spray during that short cycle quickly confirms a failing hose or loose clamp.
Frequently Asked Questions
How long should a replacement drain hose be for a Kenmore 800 washer?
Most replacement hoses are 3–8 feet long. Measure the distance from the washer pump outlet to your standpipe/drain location and pick a hose a little longer than that so you can make a high loop (prevents siphoning). If you have an uncommon install, use the model tag to order a model-specific hose.
Can I use a universal drain hose instead of an OEM Kenmore part?
Yes — many people use a universal washer drain hose successfully. Make sure the inner diameter matches the pump outlet (typically about 1.25"–1.5"), the hose is long enough, and you secure it with proper clamps. If the pump outlet or cabinet mounting requires a specific molded end, you may need the OEM hose or adapter.
