Client Problem
📍 Location
Karen, Nairobi, Kenya
🏠 Client
Residential home with a Samsung front-loading washing machine
The client contacted Garblex Home Solutions after their Samsung washing machine door would not open after completing a cycle. The display showed a door lock error code, preventing the machine from starting any new cycles.
The client had attempted basic troubleshooting, including switching the machine off and unplugging it, but the door remained locked. Forcing the door posed a high risk of damaging the latch, hinges, or drum, so they requested professional on-site washing machine repair in Karen.
🧠 Professional Skills Applied
Our certified technician applied the following professional skills during diagnosis and repair:
- Samsung-specific diagnostics – Deep understanding of Samsung door lock systems and error codes
- Electrical troubleshooting – Testing the door lock assembly and PCB signal continuity
- Mechanical inspection – Assessing drum alignment, door hinges, and latch mechanism
- Error code interpretation – Accurate analysis of Samsung DE / door lock fault codes
- Preventive maintenance checks – Inspecting drainage, hoses, seals, and filters
- Safe handling techniques – Unlocking the door without causing physical damage
Step-by-Step Diagnosis
After a systematic inspection, our technician identified multiple contributing issues:
Faulty door lock mechanism – The latch solenoid failed to disengage after the cycle
Residual water in the drum – Even minimal water triggered Samsung’s safety lock system
Minor drum misalignment – Added pressure on the door latch during spin cycles
Stored PCB error signals – Repeated door lock errors recorded by the control board

The following professional repairs were carried out on-site:
Door lock replacement – Installed a Samsung-compatible OEM door lock assembly
Drum realignment – Corrected alignment to reduce strain on the door mechanism
Drainage inspection and cleaning – Removed residual water and cleared hoses
PCB reset and diagnostics – Cleared stored error codes and confirmed stable signals
Full operational testing – Completed wash, rinse, and spin cycles successfully
✅ Results
- Washing machine door opens and closes smoothly
- DE / door lock error codes fully resolved
- Machine runs quietly with no leaks or excessive vibration
- Client resumed normal laundry use immediately
