This water inlet valve controls incoming water flow to the appliance, ensuring proper fill during cycles and helping prevent overfilling. Replaces a worn or leaking valve to restore normal water delivery and cycle performance. What it does:

• Opens and closes to allow water into the appliance when a cycle requests fill.
• Prevents water flow when the machine is idle, helping avoid leaks or flooding.
• Commonly fails when leaking, not filling, or filling continuously.
• Electromechanical valve operated by the appliance's control board or timer.

• One water inlet valve

• Disconnect power and turn off the water supply before starting any work.
• Verify valve orientation and hose connections match the appliance before finalizing installation.
• Inspect inlet hoses and clamps for damage; replace if brittle or cracked.

• Do not overtighten; snug to manufacturer torque recommendations if available
• If threads are damaged, replace the mating nut or insert as needed

This retaining nut secures threaded connections on compatible Bosch appliances to keep components tight and stable during operation. A small replacement that restores proper fastening and prevents parts from loosening. What it does:

• Fastens and secures mating threaded components to maintain mechanical stability
• Prevents vibration-induced loosening of attached parts
• Helps maintain proper alignment of secured components during use
• Can stop intermittent movement or rattling caused by a missing or damaged nut

• Turn off and unplug the appliance before servicing to avoid shock or injury
• Verify correct nut location and thread engagement before tightening; do not force threads
• Tighten to snug fit—avoid overtightening which can strip threads or damage components

This replacement rail restores smooth rack movement and proper alignment in compatible dishwashers. It helps support the rack and keep rollers on track so the rack slides in and out without binding. What it does

• Supports and guides a dishwasher rack so it rolls smoothly along its track
• Helps prevent the rack from slipping off or catching while opening or closing
• Can reduce grinding or scraping noises caused by a damaged or bent rail
• Restores proper rack alignment for reliable loading and unloading

• One rail

• Turn off power to the appliance before beginning any service
• Remove the affected rack and rollers as needed to access and replace the rail
• Inspect rollers and mounting clips; replace any worn hardware to ensure proper fit

This replacement hose clamp secures a hose to its fitting to maintain a tight, leak-resistant seal. Replacing a worn clamp helps stop drips and keeps fill, drain, or circulation lines firmly in place for reliable operation.

• Applies clamping force to hold a hose on a barb or stub connection
• Helps prevent leaks at hose joints
• Common symptoms: water leaking at a hose connection, hose slipping off, poor fill or drain performance
• Replace when the original is loose, corroded, distorted, or lost tension; also recommended when installing a new hose

• Disconnect power and shut off water supply before servicing
• Expect some residual water; protect the work area
• Note the clamp's position/orientation; use appropriate hand tools for the clamp style
• Ensure the hose is fully seated and clamp is secure; run a test cycle and check for leaks

This genuine bearing supports smooth, low-friction rotation of a moving component inside your appliance. Replacing a worn bearing restores quiet, consistent operation and helps protect the shaft and housing from accelerated wear.

• Provides radial support and alignment for a rotating shaft or arm
• Reduces friction to improve efficiency and minimize noise
• Helps prevent wobble and uneven wear on mating parts
• Typical signs of wear: grinding/squealing sounds, rough or seized rotation, excessive play

• Disconnect power and water supply and allow hot components to cool
• Access the assembly; note the original bearing's orientation and depth
• Inspect the shaft and housing; replace if grooved, bent, or heat-damaged
• Press the new bearing in squarely; avoid striking the inner/outer race and verify free rotation before reassembly

This is the appliance's main power on/off switch. It restores reliable control of electrical power to the unit so you can turn it on and off consistently.

• Controls AC power to the appliance's user interface and electronics
• Worn or stuck switch can cause no power, intermittent power, or inability to shut off
• Spongy or loose button feel may indicate internal switch failure

• Disconnect power before service to avoid electrical shock
• Access typically requires removing the control panel or console
• Note wire positions or take a photo before disconnecting
• Do not force tabs; transfer any clips or boots from the old switch if present

This suspension damper stabilizes the tub/drum by absorbing movement and vibration during operation. Replacing a worn damper helps reduce shaking and noise, improving spin performance and overall machine stability. What it does:

• Absorbs and controls tub/drum movement to reduce vibration and noise
• Helps prevent banging, "walking," or out-of-balance shutdowns during spin
• Can address excessive shaking, rattling, and longer spin times
• Restores smoother, more controlled operation when the original damper is worn

• One suspension damper

• Disconnect power and turn off water supply before servicing
• Access location varies by model; support the tub/drum to relieve load before removal
• Note orientation and reuse existing mounting hardware if new fasteners aren't provided
• After installation, re-level the appliance and run a test cycle to verify stability

• Guides overflow water away from the tub into the proper return/drain path
• Helps maintain correct water level during fill
• Can address water collecting in the base pan or leaking from the lower front area
• Useful when the leak protection/float has been tripped or cycles stop due to a detected leak

• Disconnect power and turn off the water supply before servicing
• Access the overflow/water-channel area per your model's service procedure
• Note orientation and transfer any clips or seals from the old part if present
• Reassemble, restore power/water, and run a short cycle to check for leaks
