Customer Questions and Answers for Drain Hose by Bosch

The Drain Hose is an OEM component for Bosch dishwashers. It is a flexible plastic tube responsible for removing used wash water from the dishwasher sump to household drain plumbing located outside the appliance.

Causes of a bad drain hose include cracks developing along joints from constant bending during drainage or mineral buildup restricting water flow over time.

Symptoms of a bad drain hose involve:

• Water failing to completely drain from the bottom tub area
• Puddles or residual standing water remaining after cycles
• Drainage that is slower than usual or takes multiple attempts
• Mineral deposits left inside the hose obstructing its bore

This OEM Bosch part can also be used on Thermador and Gaggenau appliances.
