AEG 6051-042.239666
Product Name: Electronic Control Module (Main PCB — Inverter Variant)
Model Series: 6051 Series — Inverter Motor Control Board
Applicable Products: AEG Front-Loading Washing Machines with Inverter Motor (Lavamat, ÖKOMix, ProSteam, L9 series)
Product Description:
The AEG 6051-042.239666 is a main electronic control board with integrated inverter motor drive for AEG front-loading washing machines equipped with brushless DC (BLDC) or inverter-driven AC motors. Unlike the standard 6054 series, this board directly controls the inverter power stage (IGBT module) that drives the motor, enabling precise speed control, energy efficiency, and quiet operation.

- Current sensing: Real-time motor current monitoring for overload protection
- Error diagnostics: Stores up to 30 fault codes with timestamps
- Energy optimization: Adjusts motor power dynamically based on load weight (auto-detection via tacho signal)
Materials:
- PCB: FR-4, 4-layer, 2oz copper, HASL finish
- Power Components: IGBT module (Infineon / STMicroelectronics), electrolytic capacitors (105°C rated), toroidal inductors
- Connectors: JST-VH / Molex Mini-Fit Jr. locking connectors
- Enclosure: No enclosure — board-level component, mounted inside machine cabinet
Advantages Over Standard 6054 Board:
| Feature | 6054 Board | 6051 Board |
|---|---|---|
| Motor Control | Triac (fixed speed) | Inverter (variable speed) |
| Energy Efficiency | A+ to A++ | A+++ |
| Noise Level | 55–65 dB | 44–52 dB |
| Spin Speed | 1200 RPM max | 1400–1600 RPM |
| Motor Type | Universal / Induction | BLDC / Inverter AC |
Installation Requirements:
- Must be installed by qualified technician — inverter board carries mains voltage on power stage
- All connectors must be fully mated — partial connection causes motor stutter or E-codes
- Perform inverter calibration after board replacement using service mode
- Ground the heatsink — IGBT module heatsink must be connected to chassis earth
