Hi @anre0828, 

Welcome to the Dyson Community!

This sounds like an unusual issue, and to help pinpoint the cause we'll need our Customer Care experts to take you through some further troubleshooting checks when you have your Dyson Corrale straightener easily to hand. If a replacement part or a repair is needed, they’ll be able to confirm if this is covered under your Dyson warranty.

Please visit Dyson.com and click the round purple button to launch the Dyson Digital Assistant. Then click the agent icon in the bottom left corner of the chat window to start a conversation with our Customer Care team. 

We'll look forward to speaking with you!
