If you’re troubleshooting restricted flow on a Multiple brands unit, the Hose (part 02-3888-01) is a common replacement item. Depending on installation, failure can present as restricted flow, intermittent operation, abnormal noise, or a cycle that won’t complete normally. After replacement, run at least one full cycle and recheck for leaks, vibration noise, and fasteners that loosen during operation. Tubes and connectors route water and drain flow. Splits, kinks, or loose connections lead to leaks or restricted distribution. Match the part number 02-3888-01 to the old component before ordering, then reinstall with careful alignment and routing. A correct-fit replacement helps restore predictable operation and reduces repeat service calls. Clean the area around the repair so debris doesn’t interfere with fitment or sealing surfaces. Take a photo before disassembly so you can confirm orientation and fastener locations during reassembly. Clean the area around the repair so debris doesn’t interfere with fitment or sealing surfaces.
