Parts for Bosch HMV3022U/02: Control Panel Parts

This Electronic PC Board—also called a control board—serves as the appliance's central controller, coordinating inputs and outputs to run cycles. Replacing a failed board helps restore reliable power-up, cycle control, and normal operation.

• Distributes power to components according to programmed cycles
• Interprets user commands and sensor/safety-switch signals
• Controls timing and sequencing to start, run, and complete cycles
• Common signs of a failing board include no power or won't start, unresponsive controls, or cycles that stop mid-way
• Visible board damage or persistent error codes traced to the control can also indicate failure

• Disconnect power to the appliance; shut off water supply if applicable
• Use ESD protection; handle the board by its edges and avoid touching components
• Photograph wiring and move connectors one at a time to matching terminals
• Some models require configuration/programming after installation—follow the service documentation for your unit

This is a replacement mounting nut used to secure components on compatible Bosch appliances. It restores proper fastening to reduce movement and noise from loose connections. What it does:

• Secures panels, assemblies or brackets to prevent shifting during operation
• Restores proper clamp force where a stripped or missing nut causes looseness
• Helps eliminate rattling or vibration caused by unsecured parts
• Provides a direct replacement for the original fastener

• Turn off and unplug the appliance or shut off power at the breaker before servicing
• Use the correct-size wrench or socket to avoid rounding the nut
• Tighten to a snug fit; avoid over-tightening which can strip threads or damage parts
