Parts for Bosch HMC80252UC/01: Control Panel Parts

This electronic control unit manages a appliance's automatic functions and cycle logic, restoring responsive controls and normal cycle operation when the original control board fails. Replaces the appliance's main electronic control module. What it does:

• Interprets user inputs and runs wash/dry/heating cycles according to selected settings
• Controls timers, valves, pumps and other components via relay and sensor signals
• Resolves symptoms such as unresponsive control panel, no cycles starting, or intermittent operation
• Works with the appliance's existing wiring harness and user interface to coordinate functions

• Disconnect power to the appliance before beginning work to avoid shock or damage
• Handle the board carefully to avoid static discharge and connector damage
• Installation typically requires access to the console or inner panel and removal of mounting screws; retain all hardware

This electronic control unit manages the dishwasher's wash cycles and user interface so the appliance runs the selected programs and responds to controls. It replaces a failed or malfunctioning main control. What it does

• Sends power and timing signals to valves, pumps, and heaters to execute selected cycles
• Interprets inputs from the control panel and user buttons so settings operate correctly
• Reads sensor/status inputs and coordinates cycle steps; may stop operation if faults detected
• Common symptoms: no response from controls, cycles won't start or advance, display/LEDs flashing or showing errors, or erratic cycle behavior

• One control unit

• Disconnect power to the appliance before servicing to avoid shock or damage
• Handle the board carefully; avoid ESD (static) damage and do not touch circuitry
• Reconnect all wiring harnesses exactly as removed; ensure connectors seat fully

This replacement screw secures appliance panels and components at their mounting points. Swap in a new screw to restore a tight, rattle-free fit when the original fastener is missing, stripped, or corroded.

• Fastens the designated panel, bracket, or component in place
• Replaces a missing, stripped, or rusted screw
• Helps address loose panels, gaps, rattling, or misalignment at the mounting point
• Maintains proper assembly integrity after service or vibration

• Disconnect power; shut off water supply if working near plumbing
• Match to the removed fastener and replace one at a time to preserve alignment
• Start threads by hand to avoid cross-threading; use the correct driver bit
• Tighten snugly and avoid overtightening, especially into plastic or thin sheet metal
