The Electrode is an OEM part for Bosch gas ranges. It is a component responsible for generating the spark required to ignite gas burners on the cooktop. 

Causes of a bad electrode can include cracks, deterioration, or damage over time from repeated exposure to high heat during use. Corrosion from spills or residue buildup can also potentially compromise function.

Symptoms of a bad electrode include:

• Difficulty lighting one or more gas burners  
• Burners lighting intermittently or inconsistently
• Small flames or burners failing to light entirely
• Burners extinguishing unexpectedly 

This part is also compatible with some Thermador, Gaggenau and Kenmore gas cooktop models.

The Screw is an OEM part for Bosch ranges. It plays a crucial role in connecting and securing range components and panels. Over time, screws can strip, corrode, or break, preventing tight connections and proper alignment of parts.

Causes can include normal wear and tear over time, as well as damage during repair or maintenance. Replacing missing or faulty screws with genuine OEM parts is important to ensure the range operates as designed and presents no safety issues.

Symptoms of bad or missing screws include:

• Doors, panels, or panels not sitting flush
• Components detaching or coming loose
• Alignment issues between connected parts
• Reduced structural integrity

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

This replacement tube routes water between internal components to maintain a sealed, reliable flow path. Swapping a cracked or hardened tube helps stop leaks and restore proper circulation and overall appliance performance.

• Carries water between internal components and maintains proper flow
• Helps keep connections watertight to prevent drips and pooling
• Replace if you see leaks, visible cracks, kinks, or a loose fit
• Restricted flow from a worn tube can contribute to reduced cleaning/performance

• Disconnect power and turn off the water supply before servicing; allow the unit to cool
• Remove access panels and keep towels handy for residual water
• Note the original routing and connection depth; transfer any fittings or clamps from the old tube if applicable
• Push the tube fully onto fittings and secure; run a test cycle and check carefully for leaks

This screw secures appliance panels and internal components. Replacing a missing, rusted, or stripped fastener restores proper fit and alignment to prevent movement, rattling, and premature wear.

• Fastens appliance components and panels for a secure assembly
• Helps maintain proper alignment to reduce vibration and noise
• Replaces missing or damaged hardware that can cause loose fits
• Supports reliable operation after service or repair

• Disconnect power and, shut off water or gas before service
• Use the correct driver for the head type; start threads by hand to avoid cross-threading
• Tighten evenly and do not overtighten to prevent stripping or damage

A replacement hob top that restores the cooktop's upper surface for safe, stable burner operation and a clean appearance. Fits the listed Bosch cooktop assemblies and replaces worn, dented, or damaged top panels. What it does:

• Replaces the cooktop's upper surface to provide a stable mounting area for burners and grates
• Helps prevent heat and spills from reaching internal components
• Commonly used when the top is dented, cracked, warped, or shows heavy wear
• Restores proper fit and alignment of burner assemblies and trim

• One hob top (single top panel) as shown

• Disconnect power and gas before beginning repairs
• Handle carefully to avoid bending or scratching the panel; use protective gloves

This Jet is the small spray nozzle that directs a focused stream of water inside the dishwasher's wash system. Replacing a clogged or damaged jet helps restore proper spray coverage, wash pressure, and overall cleaning performance.

• Directs and meters water flow within the wash system
• Helps maintain spray arm/wash zone pressure and coverage
• Replace if clogged with mineral deposits or physically damaged
• Symptoms include poor cleaning, weak spray, unusual wash noise, or leaks near the nozzle

• Disconnect power and shut off the water supply before servicing
• Access the nozzle location and note its orientation and any seals/clips
• Clean mating surfaces; transfer any reusable seal/clip if present
• Seat and lock the jet fully; run a test cycle and check for leaks

This connector strip is the wire terminal block that joins appliance wiring harnesses for reliable electrical connections, helping restore power and control signal continuity. It's a direct-fit replacement when the original connector is damaged or burned. What it does:

• Provides a secure termination point for multiple wires so circuits can complete and controls receive power.
• Replaces corroded, loose, or burned terminals that cause intermittent power, no-heat or no-power issues.
• Maintains correct wiring alignment to prevent shorts or poor contact.
• Helps eliminate symptoms like a blank display, burners or elements not powering, or sporadic operation tied to a bad connection.

• Always disconnect power to the appliance (unplug or switch off breaker) before inspecting or replacing electrical parts.
• Verify wire locations and take a photo before removal to preserve proper wiring order.
• Replace only if terminals are visibly damaged, loose, or show signs of burning; secure all screws/nuts to factory tightness.
