If turbulence or loss of suction occurs, check the motor housing seal first–common failure points include warped gaskets or debris buildup along the cyclonic separation chamber’s inner rim. Replace the seal if gaps exceed 0.5mm; use OEM part #WH-2023-B for models released post-2018. For older units, silicone-based adhesive (Loctite 515) reinforces worn edges temporarily.
