Detailed content
Key Specifications:
| Parameter | Value |
|---|---|
| Part Number | 110CPU41102 |
| Board Type | Main Control PCB (Mainboard) |
| Microcontroller | 32-bit ARM Cortex-M series MCU |
| Operating Voltage | 3.3V / 5V / 12V / 230V (multi-rail) |
| Communication Protocol | I²C, SPI, UART (for display and sensor interfaces) |
| Input Channels | Water level sensor, temperature sensor (NTC), door lock switch, pressure switch, tachometer |
| Output Channels | Motor triac driver, water valve solenoid, heater relay, drain pump relay, display driver |

Functional Features:
- 16+ Wash Program Management including cotton, synthetic, wool, quick wash, eco cycle
- Variable Motor Speed Control via triac phase-angle firing
- Temperature Regulation with dual NTC sensor input (drum + water inlet)
- Anti-Flood Protection with dual water level monitoring
- Imbalance Detection via tachometer feedback — triggers redistribution cycle
- Child Lock & Delay Start logic
Material Composition:
- PCB Substrate: FR-4 glass epoxy (Tg 170°C)
- Surface Finish: HASL (Lead-free)
- Component Mounting: SMD + Through-hole hybrid
Installation Requirement:
- Replace only with exact part number match.
- Ensure all connector pins are fully seated — partial connection causes error codes.
- Perform full system reset after board replacement (hold start/pause for 5 seconds).
Usage Notes:
- Do not expose to moisture or condensation.
- Voltage surges above 260V will damage the triac output stage permanently.
- Use a surge protector rated at minimum 1000J.
