Model issues and repair guidance

Use a direct power-unit test to keep building tubing separate from the collection canister. Clear the hose and affected branch first, then inspect the pail seal and documented filter before control, fan, or motor work. If suction changes after the lower canister is removed, inspect both oversized latch points and the complete rim gasket for an uneven seal before checking the internal fan path.Compare several inlets with the utility port; broad loss moves to pail, filter, and seal, while one weak branch stays in hose or tubing. A change after pail service points to both latch points and the rim gasket before the internal fan path.
