Bosch 668109 Sump Drain Hose Replacement Part

Product Description

The BOSCH 668109 is an OEM-style replacement sump drain hose designed to restore proper drainage function in dishwasher appliances. The sump drain hose connects the sump assembly at the base of the dishwasher to the drain pump or outlet, allowing wastewater to exit the unit during and after wash cycles. This part addresses common failure points caused by everyday wear, cracking, or blockage in the drain path. Installation is typically performed by appliance repair technicians or qualified service pros during routine maintenance or in response to standing water or drainage error codes.

This replacement hose is suited for residential dishwasher applications where the original sump drain hose has degraded, kinked, or become damaged over time. It is manufactured to OEM specifications to ensure a precise fit and reliable seal at connection points. Technicians servicing Bosch-brand dishwashers will find this part a direct drop-in replacement for the original component, minimizing diagnostic time and callbacks.

Installation Notes

Installation should be performed by a qualified appliance technician. Disconnect power to the dishwasher at the breaker and shut off the water supply before beginning any service. Access to the sump area typically requires removing the lower spray arm, filter assembly, and in some models the kick plate or lower panel. Inspect all clamps and connection points for wear when replacing the hose, and ensure all fittings are fully seated before restoring power and running a test cycle.
