Bosch Washer Gasket & Seal

This water inlet hose gasket seals the connection between the supply hose and the appliance's inlet fitting. Replace a flattened or damaged washer to stop drips at the coupling and restore a reliable, watertight connection.

• Creates a watertight seal at the inlet hose-to-appliance connection
• Helps prevent drips, puddles, and water damage around the machine
• Replace if the old gasket is cracked, hardened, flattened, or missing
• Common symptoms: leaking at the hose coupling or needing to retighten the fitting to stop drips

• Disconnect power and turn off the water supply before servicing
• Place a towel to catch residual water, then detach the inlet hose from the appliance fitting
• Remove the old gasket from the hose coupling and seat the new gasket evenly
• Reattach and hand-tighten the coupling; open water supply and check for leaks—do not overtighten

This O-ring is a small rubber seal that prevents water leaks by sealing a connection point inside your appliance. It's a simple, inexpensive part that restores a watertight joint when the original O-ring is worn or damaged. What it does:

• Seals mating surfaces to stop or prevent water leaks at fittings and connections
• Maintains pressure integrity in fluid pathways
• Replaces cracked, flattened, or hardened O-rings that allow dripping or seepage
• Helps restore normal operation by re-establishing proper sealing where the original failed

• Disconnect power and shut off the water supply before replacing any seals
• Remove the damaged O-ring and clean mating surfaces; ensure the replacement seats evenly
• Inspect surrounding parts for damage; replace additional worn components as needed
• Do not stretch or nick the O-ring during installation; use the correct size for a proper seal
