The Thread Bolt is an OEM part for Bosch dishwashers. It serves as a fastening component, securing the water inlet in place and ensuring a proper water supply connection.

Causes of a malfunctioning Thread Bolt can include cross-threading or over-tightening during installation, leading to stripping or damage.  

Symptoms of a bad Thread Bolt include:

• Leaks around the water inlet area Loose or rattling water inlet valve 
• Difficulty in accessing or removing the valve assembly 

This genuine OEM Bosch part is also compatible with Thermador, Gaggenau and select Kenmore models.

The Funnel is an OEM part for Bosch dishwashers. It helps accurately guide water from the inlet valve onto wash arms and other components inside the dishwasher.

As water flows through the funnel during each cycle, small debris particles can become trapped. Over time, a buildup of mineral deposits or grime occurs inside the funnel.

Causes are normal mineral accumulation from hard water, along with food particles or grit trapped during dishwasher use.

Symptoms of a bad funnel include:

• Reduced or uneven water pressure to spray arms
• Clogs or blockages that hamper water flow
• Mineral deposits visible inside the funnel

This genuine OEM Bosch part is also compatible with Thermador, Gaggenau and select Kenmore models.

This operating module is the dishwasher's electronic control board that runs the user interface and manages wash cycles, displays, and touch/selection inputs for reliable cleaning performance. What it does:

• Controls cycle selection, start/pause, and display indicators
• Communicates with sensors and valves to sequence wash, drain, and dry functions
• Restores responsive touch/buttons and correct cycle reporting when a failed control causes no power or unresponsive controls
• Helps resolve intermittent errors, blank displays, or failure to start tied to the main user/control electronics

• Disconnect power at the breaker before inspecting or replacing the module
• Access typically requires removing the control panel; keep screws and panels organized
• Handle the board by edges and avoid static discharge; do not touch electronic contacts

This temperature sensor (thermistor) measures appliance temperature and sends a signal to the control board so the unit can maintain proper cooling cycles. Replaces a failed or intermittent sensor for more reliable temperature control. What it does:

• Detects internal temperature and provides a changing resistance signal to the control board
• Helps the control board regulate compressor and fan operation for consistent cooling
• Commonly linked to symptoms like incorrect temperatures, frequent cycling, or related error codes
• Works as a direct-replacement sensing element

• One temperature sensor (thermistor) as pictured

• Disconnect power before servicing to avoid shock or damage
• Handle the sensor and wiring gently; avoid kinking or pinching the harness
• Access may require removing interior panels or covers; keep mounting hardware for reinstallation
• Test with a multimeter or follow OEM service instructions before replacement

The Prolongation is an OEM replacement part for Bosch dishwashers that connects the dishwasher to the water supply, allowing for the proper filling of water during the wash cycles. It ensures a secure and leak-free connection between your dishwasher and the water source. It is designed to withstand the water pressure and temperature variations, providing a reliable and consistent water supply for your dishwasher.

A bad prolongation can occur due to wear and tear, damage, or improper installation. Signs of a faulty fill hose include leaks, cracks, or a decrease in water flow.

Symptoms of a bad prolongation include:

• Water leaks around the connection points  
• Reduced water flow or inadequate water supply 
• Visible cracks or damage to the fill hose  

Replace your worn-out or damaged prolongation with this genuine OEM Bosch part to restore your dishwasher. This Bosch part can also be used on Thermador and Gaggenau appliances.
 

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 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

This regeneration valve directs brine through your dishwasher's built-in water softener during recharge cycles, helping prevent hard-water film and spotting. Replacing a faulty valve restores consistent softening and better cleaning results.

• Opens to route salt brine through the ion-exchange resin during regeneration
• Helps maintain proper water hardness feeding the wash system
• 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
