Parts for Thermador TSS48DAB-06: 15 - Lower Unit & Tubing Parts

This discharge tube directs wastewater from the appliance's pump to its drain, preventing leaks and enabling proper drainage. It restores reliable water flow so the appliance can empty as designed. What it does:

• Channels pumped wastewater from the pump outlet to the drain line or drain pump housing
• Replaces cracked, brittle, or clogged discharge tubing that causes leaks or reduced drainage
• Helps resolve symptoms like water pooling in the tub, incomplete drain cycles, or water under the appliance
• Works as the fluid path between pump and drain—fits into existing clamps and fittings

• Disconnect power and water supply before beginning any repair
• Inspect and replace any worn clamps or fittings when installing the tube
• Ensure proper routing and secure clamps to avoid kinks or chafing

This defrost heater melts frost and ice from the evaporator to help restore normal airflow and cooling performance. It replaces a failed heater to reduce excessive frost buildup and repeated frost cycles. What it does:

• Heats the evaporator during the defrost cycle so accumulated frost and ice melt away
• Helps prevent airflow restriction and reduced cooling caused by frozen evaporator coils
• Commonly replaced when you see excessive frost, frequent defrost cycles, or poor cooling in the refrigerator/freezer
• Works with the freezer's defrost control system (timer/thermostat/board) to run only during defrost

• Disconnect power before servicing to avoid shock or injury
• Inspect surrounding components (defrost thermostat/thermistor and wiring) for damage; replace if faulty
• Handle the evaporator and heater carefully—avoid bending coils or damaging fins

This drain pan collects and channels defrost and condensation water away from the evaporator to prevent leaking and overflow. Use this replacement to restore proper water flow and reduce pooling under the appliance. What it does:

• Catches defrost and condensate from the evaporator system
• Directs water toward the drain or evaporator heater for evaporation
• Helps prevent water leaks, puddling, and potential floor damage
• Supports normal defrost cycle drainage

• Disconnect power to the appliance before service
• Remove access panels or kickplate to reach the pan; keep small fasteners organized
• Clean surrounding area and drain path before installing the new pan
