The 6 µF capacitor is an electrical starting element of the motor of the ESPA NIPER pump, which provides the necessary phase shift for reliable startup of the single-phase asynchronous motor.
A capacitor defect manifests itself in typical symptoms: the motor hums without starting, overheats excessively, or repeatedly trips the thermal fuse.
The 6 µF capacitance is precisely dimensioned for the NIPER pump motor and guarantees optimal starting torque without overloading the winding.
Replacing a defective capacitor is the most common and cheapest repair for an electrical fault of a pool pump – the part is easily accessible after removing the motor cover.
