How to Fix / Troubleshooting

Safety first: Unplug the machine before accessing the switch area.

External check: Press the switch repeatedly with the machine unplugged. If it feels spongy, sticks, or does not click, the internal mechanism may be worn.
Wiring inspection: If you can safely remove the switch cover, check that spade terminals are firmly attached and there are no signs of overheating or melting.
Switch replacement: The most reliable fix for an intermittent switch is replacement with a genuine SEBO switch. This typically involves removing the outer housing and desoldering or disconnecting the old switch.
Professional help: If you are not experienced with electrical work, have a technician replace the switch to ensure safe wiring and insulation.

Do not spray cleaners or lubricants into the switch; this can worsen contact problems and create a fire risk.
