Parts for Bosch WTG86400UC/02: Control Panel Parts

This is the program selector knob that mounts on the control panel's selector switch. It lets you grip and turn the program switch to choose cycles; replacing a cracked or loose knob restores smooth, accurate selection. What it does:

• Attaches to the selector switch shaft so you can set programs/cycles
• Provides a secure grip and proper indexing of cycle positions
• Keeps selections aligned with the control markings for accurate settings
• Common symptoms: cracked/broken knob, spins freely or falls off, cannot select cycles, or must turn the bare shaft with pliers

• 1 program selector knob

• Disconnect power to the appliance before servicing
• Pull the old knob straight off the selector shaft; apply even, straight pressure to avoid stressing the control panel
• Align the keyed hub/orientation with the shaft and press firmly until fully seated
• Rotate through all positions to ensure smooth engagement and correct alignment

This coupling connects the dishwasher motor to the wash pump so the motor can drive the impeller for normal water circulation. Replacing a worn coupling restores drive between motor and pump and helps the dishwasher pump water effectively. What it does:

• Transfers rotational force from the motor to the pump impeller for wash and drain cycles
• Prevents slipping when the motor runs, ensuring consistent water circulation
• Commonly replaced when the motor runs but the pump doesn't turn or performance is reduced
• Can help stop grinding, clunking, or unusual noises coming from the pump area

• Disconnect power to the appliance before any service to avoid shock or injury
• Access usually requires removing the access panel and/or pump housing—follow OEM service instructions
• Inspect the surrounding seals and pump components when replacing the coupling; replace any damaged parts

This display mounts behind the control panel and provides the readout for settings, time, and status. Replacing a failed display restores a clear, reliable view of your appliance's operating information and alerts.

• Presents cycle/status information and remaining time as provided by the control
• Communicates prompts or fault/error indications on the control panel
• Common failure symptoms: blank/dark screen, dim or flickering display, missing/garbled segments, or intermittent readout
• Installs in the control panel area; interfaces with the appliance's main control

• Disconnect electrical power before servicing
• Remove the control panel/fascia to access the display; note connector orientation
• Handle the electronics with ESD care; avoid touching circuitry and LED elements
• Transfer any light pipes, seals, or brackets from the original part if applicable, then test before final reassembly

The Power Cord is an OEM part for Bosch electric dryers. It provides power to heating elements and motor components, enabling all dryer functions. Working seamlessly behind wall panels and the control board, the cable supply facilitates safe and reliable drying performance cycle after cycle.

Symptoms of a bad power cord include:

• The dryer fails to power on or heat
• Flickering lights or control issues  
• Burning smells coming from internal areas
• Cable sheathing showing defects or damage

Causes for failure relate to insulation breaks, fraying, or cuts to wiring over time. Accidental impact, animal/insect damage, or general wear and tear may also degrade cable supply integrity.

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

Replace a cracked or worn console facia with this facia panel. It restores a clean factory appearance and secure fit for the control area so buttons and displays align properly and the console mounts solidly.

• Provides the finished exterior trim for the control console
• Supports and aligns user interface components behind the panel
• Helps secure the console to the appliance front with correct fitment
• Common reasons to replace: cracked plastic, broken tabs, loose/rattling console, worn or damaged surface

• Disconnect power to the appliance before servicing
• Access the console, remove retaining screws/clips, and release locking tabs carefully
• Transfer any reusable components from the old panel to the new panel and verify alignment before tightening fasteners
• Avoid overtightening screws and protect the surface finish during reassembly

Pre-programmed power module—also called the main electronic control board—for the dishwasher. It manages power to pumps, heater, and valves to run each cycle correctly and can help restore operation when the original control has failed. What it does:

• Distributes power to the circulation pump, drain pump, water inlet valve, heater, and other loads
• Coordinates timing of wash, drain, and dry functions based on sensors and the user interface
• Common symptoms: no power/won't start, cycle won't advance or ends early, intermittent shutoffs
• May present as no heat, won't fill, or won't drain when related components test good

• 1 programmed power module (electronic control board)

• Disconnect power at the breaker before servicing; verify no voltage is present
• Use ESD precautions and handle the board by the edges only
• Photograph wiring and transfer connectors one at a time; ensure locks are fully seated
• Mount securely in the original location and inspect harness routing before restoring power

This programmed operating module is the appliance's user interface control. It interprets button/selector inputs, drives the display or indicator lights, and communicates with the main control so selected programs respond and run correctly.

• Interprets keypad/selector inputs and sends commands to the control system
• Powers and updates display/LED indicators and status tones
• Enables start/pause/cancel and option selections
• Typical symptoms of failure: unresponsive controls, blank/flickering display, erratic inputs, won't start a program, UI communication error codes

• Disconnect power at the breaker before servicing; allow capacitors to discharge
• Use ESD protection and handle the board by its edges
• Transfer any model-specific trim/overlay and reconnect harnesses one at a time, ensuring full seating
• After reassembly, restore power and run the appliance's test/program check for proper operation

This replacement panel insert restores the appearance and sealed edge of the appliance control area, covering the control pocket and giving a finished look while helping protect controls from spills and debris. What it does:

• Replaces a worn, cracked, or damaged control panel insert that exposes the control pocket
• Helps keep moisture, food, and grease out of the control area
• Restores a flush, finished appearance to the front control section
• Can prevent loose trim pieces from snagging or catching during use

• Panel insert replacement part

• High-level swap: remove necessary access panels or screws, lift out the old insert, and press or fasten the new insert into place
• Use basic hand tools; avoid forcing the part to prevent damage to surrounding trim
• Disconnect power to the appliance before starting work to reduce shock risk
• Replace broken or missing mounting clips or fasteners before finishing installation
