Decision path
Safe checks, in order
- 1
Confirm code and model scope
Compare the complete display and full model number with the cited manufacturer page or manual before applying any troubleshooting instruction.
Expected: The official source explicitly covers the displayed code and product family.
If not resolved: Contact manufacturer support with the full model and serial number.
- 2
Follow the official owner checks
OPn: make sure the detergent drawer is fully inserted. Ed1-Ed4: check the detergent/softener type and remove residue blocking the tray (only liquid softener is supported; powder softener must be added to the drum manually). Ed5: unplug for 60 seconds and restart.
Expected: Only the user-accessible condition identified by the official source is corrected.
If not resolved: Stop repeated resets and arrange qualified service if the code returns or the source directs service.
Reset and test
- Official 60-second unplug recovery for Ed5; others follow the checks (not called a reset).
Important: A reset may clear the display but cannot repair the underlying condition; follow only the exact model-specific manufacturer procedure.
Escalation point
Stop and arrange service when
- The code returns after the cited user-accessible checks or the official source directs professional service.
- The equipment leaks, smells burned or of gas, smokes, sparks, overheats, or trips a breaker.
