What to do if the motor protection switch Q2/Q3 is triggered in my Hydac Water Filtration System?
- MMrs. Angela SimonAug 12, 2025
If the motor protection switch Q2/Q3 in your Hydac Water Filtration System is triggered, it indicates that the electric motor of the evacuation or vacuum pump is overloaded. To resolve this, switch on the motor protection in the electronic control unit, check the operating viscosity, drain fluid from the vacuum pump, rinse, and refill with fresh water.
