What does 'Control is hot' mean on my Kärcher Floor Machine?
- KKendra LewisAug 31, 2025
If your Kärcher Floor Machine displays 'Control is hot! Allow to cool down!', turn the safety switch to the "0" position. Allow the control to cool down for at least 5 minutes. Reduce the brush pressure significantly if you are on rough ground. If the issue continues, contact aftersales service.
