This umbrella-style seal fits around the dishwasher pump shaft to help prevent water from leaking between the pump and the tub. It keeps the pump assembly sealed so your dishwasher can drain and run without unwanted leaks. What it does:

• Forms a flexible watertight barrier around the pump shaft to reduce leaks at the pump/tub interface
• Helps maintain proper drainage by keeping pump openings sealed
• Commonly replaced when you find water pooling under the dishwasher or active leaks near the pump area
• Designed to resist dishwasher detergents and typical wash temperatures

• Disconnect power and shut off water before starting any repair.
• Access typically requires removing the dishwasher toe kick and possibly the pump assembly; follow the service manual for your model.
• Inspect the pump housing and surrounding seals/fasteners; replace any damaged components to restore a reliable seal.

This bypass jet (.31) directs precise flow inside the appliance to restore correct fluid or gas passage where the original jet is worn or clogged. Use when flow issues or inconsistent performance are traced to the jet. What it does

• Replaces the factory bypass jet to re-establish proper flow through the relevant valve or passage.
• Helps correct symptoms such as reduced flow, uneven delivery, or functional inconsistencies tied to a worn or blocked jet.
• Works as a direct-fit service part when the original jet is damaged, corroded, or improperly seated.

• One bypass jet (.31) as shown

• Installed in a valve or assembly; access may require partial disassembly.
• Turn off power and shut off water/gas supply before starting work.

• Helps maintain proper water flow into the machine by ensuring a tight connection
• Commonly used when the inlet hose connection leaks or water drips from the valve area
• Durable rubber construction suitable for standard household water pressures

• One valve inlet washer

• Turn off water supply and unplug the appliance before beginning work
• Remove the inlet hose, replace the old washer with the new one, and reattach the hose hand-tight; finish with a wrench only as needed to avoid over-tightening
• Inspect hose and valve fittings for damage or corrosion; replace damaged parts as necessary

The Spark Ignition Switch is an OEM part for Bosch ranges and cooktops. It controls the ignition of surface burner flames by emitting an electrical spark when activated.

Causes of a bad switch can be general wear and fatigue over thousands of start cycles. Exposure to moisture, dust or metal debris could also damage electrical components internally.

Symptoms of a bad spark ignition switch include:

• Burners failing to light even when valves are turned on
• Intermittent or irregular lighting of some burners
• No electrical sparks emitted from the ignition electrode

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