Frequently Asked Questions
Why does my Dyson keep cutting out after a few minutes?
Repeated cut-outs almost always indicate a restricted airway. The most common culprit is a dirty filter or a partial blockage in the wand or cleaner head that restricts airflow.
How long should I wait before restarting a Dyson that has cut out?
Wait at least 30 minutes after a thermal cut-out before restarting. Using the vacuum before it has cooled fully can trigger another cut-out immediately.
Can overheating permanently damage a Dyson?
Occasional thermal cut-outs are a safety feature and cause no damage. Repeated overheating from chronic blockages or a missing filter can shorten motor life over time.
