Before starting
Use only the instructions supplied for your exact model. If there is a leak, smoke, hot wiring or gas smell, stop and seek qualified help.
1. Check safety first
Leaks, smoke, electrical trips or gas odor take priority over troubleshooting. Stop and contact the appropriate service.
2. Read the exact model label
Record Model, E-Nr or PNC from the appliance label. Do not post private serial numbers publicly.
3. Describe the sequence
State which cycle, stage, approximate time, sound, smell or leak occurred. Do not recreate unsafe faults.
4. Ask for the basis of diagnosis
Which test found the defect? Is the replacement compatible? What are the total cost, warranty and approval terms?
