• Failure can lead to white film/spots, cloudy glassware, mineral buildup, and reduced cleaning
• Also contributes to inconsistent softener performance over time

• Disconnect power and turn off the water supply before servicing
• Access location varies by model; note hose routing and valve orientation during removal
• Inspect hoses and seals; replace if worn to prevent leaks
• Restore water/power and run a short cycle to check for leaks and proper operation

• Remove any broken fragments and clean the area before installation
• Press or snap into place carefully; do not force or overtighten any fasteners

This inlet seal is a small rubber gasket that creates a watertight connection at the dishwasher's water inlet. Replacing a worn seal helps stop leaks and ensures the inlet valve can fill the appliance properly. What it does:

• Seals the water inlet connection to prevent drips or steady leaks underneath the dishwasher
• Maintains a tight seal at the inlet valve so the fill cycle can operate normally
• Commonly replaced when there is visible wear, cracking, or persistent water on the floor
• Helps avoid water damage and the nuisance of repeated drainage or fill errors tied to leaking

• One inlet seal

• Turn off the water supply and disconnect power before servicing
• Remove the inlet valve or access panel as needed to reach the seal; replace with the old seal removed
• Make sure the new seal is seated evenly and the mating surfaces are clean before reassembly

This push button set replaces the worn or damaged control buttons on compatible Bosch appliance control panels, restoring tactile feedback and reliable user input for cycle selection and control functions. What it does:

• Replaces broken, cracked, or missing push buttons that prevent normal panel operation
• Restores proper tactile feel for selecting cycles, options, and other controls
• Helps eliminate buttons that stick, don't depress fully, or fail to register presses
• Improves appearance of the control panel when original buttons are faded or discolored

• Disconnect power to the appliance before beginning any repair to avoid shock or damage
• Typically installs from the front of the control panel; may require removing the outer panel or trim
• Handle buttons gently—do not force; align clips or posts before pressing into place

This replacement rail restores smooth, supported movement of a dishwasher rack so loading and unloading work as intended. It replaces a worn, cracked, or bent rail to stop sagging and improve rack alignment. What it does:

• Guides the dishwasher rack along its track for consistent in-and-out motion
• Supports rack weight to prevent tipping or sagging when extended
• Replaces damaged, cracked, or worn rails that cause noisy or jerky operation
• Helps restore proper rack alignment and engagement with the rollers

• Disconnect power and turn off water supply before beginning any repair.
• Remove the affected rack to access and replace the rail; keep small clips or fasteners for reassembly.
• Inspect rack rollers and mounting clips; replace any damaged components for best performance.

This bottom case is the dishwasher base assembly that protects internal components and helps contain leaks, keeping the wash system stable and secure. It's a direct-fit replacement that restores the appliance's lower enclosure. What it does

• Forms the appliance's lower enclosure to shield the pump, motor and wiring from debris
• Helps direct and contain water in the event of minor leaks to protect surrounding components
• Provides mounting surfaces for lower hardware and supports correct alignment of internal parts
• Can reduce rattles or vibration caused by a damaged or cracked lower shell

• One bottom case

• Disconnect power and water supply before beginning any repair
• Handle the part carefully to avoid damaging edges, clips or mounting tabs
• Keep fasteners and any hardware from the original unit; verify fit and alignment before tightening
• If you see water or corrosion, dry and inspect surrounding components for damage before reassembly
