What to do if Festool PLANEX switches off and the red LED flashes?
- NNicholas WalkerSep 7, 2025
If your Festool PLANEX sander switches off during operation and the red LED on the head of the machine flashes, it could be due to: * A clogged dust filter. Clean the dust filter on the PLANEX. * Excessive pressure causing the machine to activate overheating protection. Allow the machine to cool down, apply less pressure, or switch on the external extraction system and set the extraction control to setting 6 in extreme cases.
