⚠️ SAFETY WARNING: This appliance operates on 230V mains voltage. Before any inspection or disassembly, turn off the main circuit breaker or unplug the power cord. When working on the door, pay extreme attention to the mechanical risk caused by the sudden snap of the hinge springs. ReeFix provides this diagnostic report exclusively for educational and informative purposes.

QUICK TEST
- User Menu Check: Check on the G6730SC model display that the AutoOpen option has not been accidentally deactivated in the settings.
- End of Cycle Listening: During the last 15 minutes of drying, position yourself near the upper edge of the door:
- Motor hum present, but the door does not open: 55% probability (Stripped nylon gears). This often happens when the door is manually pushed inward while the pin is still extended.
- Total absence of noise: 25-30% probability (Burnt DC motor or faulty limit microswitch).
- Hinge Check: Inspect the wire harness passing through the lower hinge to rule out mechanical wire breakages.
DECISION FORK
- DIY Repair (Medium Difficulty):
If the test reveals free-running humming or mechanism blockage, you can independently replace the Miele AutoOpen door opener actuator module on eBay. A Set of precision Torx screwdrivers for Miele and about 40 minutes are required. Replacement cost: €65 – €120.
- Call a Technician:
Recommended if the wiring and actuator are intact during the test with a Professional digital multimeter on eBay, indicating an issue with the power TRIAC on the mainboard or the NTC sensor. Estimated total cost (part + labor): €115 – €210.
- Dishwasher Replacement:
Not recommended. The failure in the AutoOpen system is isolated and the low repair cost makes replacing the entire appliance uneconomical.
CONFIRMED DIAGNOSIS
In 80% of cases, the anomaly lies in the wear of the push assembly or in the mechanism of the Miele door lock and latch on eBay.
Summary report for the technician:
"Miele G6730SC: failure to activate AutoOpen at the end of drying. Check the condition of the nylon reducer teeth on the push module, electrical continuity of the DC motor winding, state of the position microswitches, and presence of the power supply signal output from the Power Module."
Prevention note: To protect the lifespan of the new component, always wait until the pin has completely retracted before closing the door.
If you hear the motor humming without door release -> replace the AutoOpen actuator; otherwise check the wiring continuity in the hinge and the output from the mainboard.
