Start at the interfaces
Map the rubber parts to the tub, cabinet, pump, dispenser and door. A door gasket is controlled by several surfaces and retention points; a connector hose is controlled by end geometry and the component positions. Keep each part tied to the same assembly revision.
Record the complete exposure cycle
Water temperature alone is incomplete. Include detergent or bleach identity, concentration, cleaning products, contact duration and whether the part dries between uses. Show movement of a tub or pump relative to the cabinet and any contact with nearby edges.
- Door seal: retention, folds, port orientation, closure and drainage.
- Drain hose: discharge duty, route, supports and end retention.
- Short connector: end fit, branches, clamp access and motion.
- Sealing sleeve: inner/outer contact surfaces and installation interference.
Make acceptance observable
Specify installation and functional checks on the real appliance: fit, closure, drainage, retention or leakage as relevant. Do not infer model compatibility, anti-mold performance or a cycle-life claim from a matching appearance.
