Parts for Bosch HMB50152UC/02: Control Panel Parts

Fixes microwaves that won't start, stop mid-cycle, or show error codes. This control board restores proper operation and display functions. Moderate DIY repair.

This electronic control board manages dishwasher cycle selection, timing and user-interface signals so the appliance runs the chosen wash programs. It restores responsive controls and proper cycle sequencing when the original board fails. What it does:

• Receives input from touchpads/controls and starts/stops wash cycles according to selected settings
• Controls timers, relays and communications between components for correct wash/drain/heating actions
• Common symptoms: unresponsive buttons, dishwasher not starting, stuck in one cycle, or inconsistent cycle behavior
• Replaces a defective main control that causes erratic or no control function

• Disconnect power at the breaker or unplug the appliance before starting work
• Handle the board by the edges and avoid static discharge; use an ESD strap if available
• Reinstall mounting screws and connector plugs securely; do not force connectors
• Follow the manufacturer's service instructions for setup, diagnostics or any required configuration
