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.
