• Helps hold inlet hoses or fittings securely in place.
• Replace if the existing ring is cracked, flattened, or leaking.
• Can resolve symptoms such as visible dripping at the inlet, loose inlet fittings, or reduced fill performance.

• Turn off water supply and power to the appliance before beginning any work.

• Fits the CW H98/HB style pump assembly and interfaces with the pump shaft and housing.
• Designed for direct OEM-fit replacement where this impeller is specified.

• Recommended for users comfortable disassembling pump housings; refer to your service manual for specific steps.
• Disconnect power and turn off the water supply before starting service.
• Inspect the pump housing, seals, and shaft for wear; replace any damaged components to prevent repeat failure.
• Use appropriate tools and handle plastic parts carefully to avoid cracking.
