How to Fix / Troubleshooting
Safety first: Ensure the appliance is unplugged before any inspection. Do not open the power supply if you are not qualified.
Step-by-step:
- 1. Check outlet and breaker: Test the wall outlet with another device and verify that the circuit breaker has not tripped.
- 2. Inspect power cord: Look for visible damage, cuts, or burn marks on the Siemens power cord and plug.
- 3. Verify main switch: Ensure the main power switch on the machine (if present) is in the ON position and not physically broken.
- 4. Internal fuse check (advanced): Remove the cover and locate the internal fuse on the power supply board. If blown, replace only with the exact Siemens-specified type and rating.
- 5. Professional repair: If the fuse blows again or the machine remains dead, the power supply or control board is likely faulty and must be serviced by Siemens.
