HAIER WASHING MACHINE PCB BOARD

About HAIER WASHING MACHINE PCB BOARD

Haier washing machine PCB (Printed Circuit Board) is the main electronic control unit that manages all operations of the washing machine through programmed circuits.

Key Functions:

• Wash Cycle Control: Automatically controls washing, rinsing, and spinning processes.
• Motor Operation: Regulates motor speed and direction for proper drum movement.
• Water Level & Inlet Control: Manages water filling and draining based on sensor inputs.
• Sensor Monitoring: Receives signals from water level sensor, lid/door switch, and temperature sensor (in some models).
• User Interface Communication: Connects with the display/control panel to execute user-selected programs.

Main Components:

• Microcontroller (main IC)
• Relays and triacs
• Capacitors and resistors
• Power supply circuit (SMPS)
• Connectors for motor, pump, valves, and sensors
