• Carries discharge water from the drain pump outlet to the home drain connection
• Damage such as splits, pinholes, or hardening can cause leaks during the drain cycle
• Kinks or blockages can lead to slow or no draining and water left in the tub
• Visible wear, brittleness, or recurring drain errors are common signs the hose needs replacement

• Disconnect power and turn off water supply before servicing
• Pull the washer forward to access; keep towels or a pan ready for residual water
• Detach the old hose from the pump/outlet and household drain; transfer and reuse clamps or brackets as required by your model
• Route the new hose without kinks, secure all connections, follow your model's manual for drain placement, then run a test drain and check for leaks

• Directs water between internal components as designed
• Maintains proper flow for filling, circulation, or draining
• Helps seal connections when correctly clamped and routed
• Common symptoms of a failed hose include leaks under the unit, slow or incomplete draining, erratic filling, or water-related error codes

• Disconnect power and shut off the water supply before servicing
• Note routing and orientation; replace one end at a time to match the original path
• Inspect and reuse OEM clamps if in good condition, or replace if corroded or weakened; fully seat all connections
• Run a brief test cycle and check all joints for leaks after installation

• Helps prevent hose detachment, air leaks, and lint escaping at the connection
• Supports proper exhaust airflow by keeping connections sealed and stable
• Common symptoms pointing to replacement: hose won't stay on, visible gaps or lint around fittings, rattling at the vent, or longer dry times from poor ventilation

• Disconnect power; for gas dryers, shut off gas supply before moving the appliance
• Slide a clamp over the hose, seat the hose fully on the collar, position clamp over the fitting, and tighten with a screwdriver or nut driver
• Do not overtighten; avoid crushing thin foil ducting; ensure the hose is straight and not kinked
• Restore power and verify strong airflow at the exterior exhaust

Includes 2 adhesive pads, 2 brackets, 4 screws, and installation instructions.

This bracket secures a component or panel inside your appliance, keeping it properly aligned and stable during operation. Replacing a bent, cracked, or missing bracket restores solid mounting and helps prevent vibration and further damage.

• Provides a rigid mounting point for a specific component or panel
• Maintains proper alignment for reliable fit and function
• Replaces damaged, deformed, or missing bracket hardware
• Typical symptoms include loose or rattling parts, misaligned panels, vibration, or components shifting out of place

• Disconnect power (and shut off water or gas, if applicable) before servicing
• Note the original bracket's orientation; transfer any reusable hardware to the new bracket
• Use existing or manufacturer-specified screws; tighten securely without over-torquing
• Verify component alignment and clearances before restoring power/service

This hose clamp secures a hose connection to prevent leaks and keep your appliance running smoothly. It provides a tight, reliable hold on the hose fitting so water or air stays contained during operation.

• Helps stop drips, seepage, or loose connections
• Common fix when you see moisture around a hose joint
• Useful if a clamp is rusted, stretched, or no longer holding tension

• Unplug power and shut off water (if applicable) before servicing
• Note clamp position/orientation before removal
• Use appropriate screwdriver or nut driver to tighten evenly
• Do not overtighten—ensure a snug, leak-free seal without damaging the hose

This factory fastener secures appliance components such as panels, brackets, and covers. Replacing a missing, stripped, or rusted screw restores a tight fit and helps reduce vibration, rattling, and shifting during operation.
