Common Questions
Why does my Dreame keep showing Error 8 even after emptying?
Dustbin sensor dirty. Remove bin, wipe sensor inside bin cavity with dry cloth. Also ensure filter not completely clogged (rinse and fully dry before use).
My L10s Ultra shows Error 13 but all contacts clean - why?
Check dock power supply. Ensure dock plugged into working outlet (not switched outlet). Try different outlet. If still failing, dock charging circuit may have failed.
Can I ignore Error 18 and keep cleaning?
No. Running with overheating motor damages motor permanently. Let cool 30 minutes, check for airflow blockages. If repeats, motor bearing worn—needs service.
Dreame error codes vs voice alerts - are they the same?
Yes. Voice alerts correspond to numbered errors. Some models only speak alerts without showing numbers. Fixes are identical whether you hear alert or see number.
How do I clear error history in Dreamehome app?
App → Settings → Cleaning Records → View Error History. Errors logged but can't be deleted. History helps diagnose recurring problems.
My Dreame shows errors in Chinese - how to change language?
Dreamehome app → Settings → Voice Language → Select English. If option missing, robot may be China-region model (not officially sold globally). Contact seller.
