Bosch Wfmc3301uc/03 Parts

This hose inlet is the molded connection that routes incoming water into the appliance and provides a sealed mating point for the fill hose. It restores proper water flow and helps prevent leaks at the hose connection. What it does

• Directs incoming water from the fill hose into the appliance's water system.
• Provides a sealed connection to prevent drips or leaks at the hose attachment.
• Can cause no-fill or slow-fill symptoms when cracked, clogged, or loose.
• Works with the inlet hose and nearby fittings to maintain correct water supply.

• Turn off power to the appliance and shut off the water supply before starting.
• Inspect and replace any damaged gaskets or clamps when installing this part.
• Hand-tighten fittings, then snug with appropriate tools; avoid overtightening plastic fittings.
• After installation, restore water and power, run a short cycle, and check all connections for leaks.

This T-shaped water hose connector routes incoming water to separate internal hose lines, restoring proper water distribution inside the appliance. It replaces a worn or cracked hose tee to stop leaks and restore flow to internal components. What it does:

• Joins three water lines so water can be directed to multiple internal points
• Stops leaks caused by cracked or damaged tee fittings at hose junctions
• Restores reliable water flow to downstream parts that depend on the split connection
• Prevents hoses from separating at a failing junction

• Turn off and disconnect the appliance from the water supply before servicing
• Inspect hose ends and clamps; replace clamps or seals if worn
• Push hoses fully onto each barb and secure with appropriate clamps
• After installation, restore water and check all connections for leaks

This fastening ring secures mating appliance components by locking parts in place to prevent movement or separation during operation. It's a simple yet essential hardware piece that helps maintain proper alignment and reliable function. What it does

• Holds mating parts together to prevent wobble, vibration, or dislocation
• Keeps seals and assemblies properly seated to reduce noise and misalignment
• Helps maintain correct component spacing for smooth operation
• Commonly replaced when the original ring is bent, worn, or missing

• Designed for use with compatible OEM assemblies; follow for correct placement
• Inspect mating surfaces and replace any damaged clips, seals, or gaskets before reassembly
• Use proper tools to avoid deforming the ring during installation; do not force into place
• Disconnect power and follow safety procedures before servicing the appliance

This temperature sensor (thermistor) measures internal temperature and sends readings to the appliance control to help maintain proper operation and cycles. It replaces a failed sensor so the control can accurately monitor temperature. What it does:

• Senses temperature and provides a variable resistance signal to the control board
• Helps the appliance regulate cooling/heating cycles and defrost timing
• Commonly associated with incorrect temperature, improper cycling, or temperature-related error codes
• Used wherever precise temperature feedback is required by the control system

• One temperature sensor (thermistor) with attached lead/harness as shown

• Disconnect power to the appliance before accessing or replacing the sensor
• Handle sensor and wiring gently; avoid pulling on the lead or bending the sensing element
• Reconnect connectors fully and route the harness away from moving parts or high-heat areas
