Understanding the Problem
A plastic tube running beside or under the washer tub often carries water between the tub, pump, and drain. When you see water coming from that area it usually means the tube itself is split, the hose connection has failed, or an adjacent fitting (clamp, elbow or pump inlet) is cracked. Leaks are most common during drain or spin cycles when water is being forced through the hose. Because many of these hoses are behind panels or under the cabinet, the exact leak point can be hard to see without a test run and inspection. Replacing a damaged hose or tightening/replacing its clamp will usually restore a watertight seal. If the plastic elbow or the pump housing is cracked where the tube attaches, the tube replacement alone won’t stop the leak — the damaged fitting or pump must be replaced too.
Common Symptoms
Visible dripping under the washer near the tub area; puddle after a wash or during spin; wet floor only during drain or spin cycles; water tracked from under cabinet panels.
Common Causes
- Cracked or split tub-to-pump/drain hose due to age, abrasion, or freeze damage
- Loose or missing hose clamp at hose-to-pump or hose-to-tub connection
- Cracked plastic elbow, pump inlet, or tub fitting where the hose connects

Helpful Repair Tip
Run a short drain/spin cycle with towels under the machine and a flashlight; if you see water spraying or dripping from the tube area, dry the tube, run the cycle again, and watch closely to confirm the exact leak location before ordering parts.
Frequently Asked Questions
Can I temporarily fix the leaking tube instead of replacing it?
Yes — a short-term repair can be done using a tight hose clamp, a short length of replacement vinyl tubing slipped over the damaged section, or waterproof tape as a very temporary measure. These fixes can stop water for a few washes but are not reliable long-term. Replace the damaged hose or cracked fitting as soon as possible to avoid recurrence and potential water damage.
How much does it cost to replace the leaking plastic tube and how hard is it to do?
Cost is usually low: a replacement hose or small length of OEM tubing typically costs $10–$40; hose clamps are under $5. If a pump or molded elbow needs replacement, parts can run $40–$150 depending on brand. Difficulty is moderate: many top- and front-loaders require removing a service panel and disconnecting the old hose, then installing the new hose and clamps. If you're comfortable with basic hand tools (screwdrivers, pliers) and unplugging the machine, you can do it in 30–90 minutes. If the pump or tub fitting is involved, or if the washer must be partially disassembled, consider a service tech.
