Astralpool Xtreme 2 & 3 motor capacitor 120 µF for ThunderJet Elite, Helios and Max 3 robots - A6012PK

Astralpool Xtreme 2 & 3 motor capacitor 120 µF for ThunderJet Elite, Helios and Max 3 robots

This is the genuine 120 µF start/run capacitor fitted inside the drive motor of the Astralpool Xtreme 2 and Xtreme 3 robotic pool cleaners — specifically the ThunderJet Elite, Helios and Max 3 motor variants. It stores and releases the electrical charge that gives the AC motor its initial torque spike and sustains stable running current, making it the single most critical passive component in the motor circuit.

Function and importance

The capacitor provides the motor with the energy burst required to reach operating speed from a standing start, then transitions to supporting continuous winding current throughout the cleaning cycle. Without a healthy capacitor rated at exactly 120 µF, the motor windings cannot generate sufficient rotating magnetic flux, leaving the robot unable to move despite receiving mains power.

Symptoms that indicate replacement is needed

A failing capacitor typically causes the robot to emit a steady hum at switch-on but refuse to drive its tracks — the motor receives power yet cannot build enough torque to spin. Physical warning signs include a visibly bulging or deformed casing, oil seepage around the terminals, or dark burn marks on the body. A capacitance reading more than 10 % below 120 µF on a digital multimeter confirms the part has degraded beyond serviceable limits and must be replaced before further use damages the motor windings.

Model compatibility

This capacitor is the correct OEM specification for the Astralpool Xtreme 2 and Xtreme 3 robot families, covering the ThunderJet Elite, Helios and Max 3 motor assemblies. Always verify your motor part number before ordering, as neighbouring Xtreme models use different capacitor values and substituting an incorrect µF rating will cause the motor to overheat or fail to start.

Why genuine Astralpool parts matter

Aftermarket capacitors are frequently sold with looser µF tolerances or lower voltage ratings than the OEM specification demands. A genuine Astralpool capacitor is manufactured to the exact capacitance and voltage rating engineered for these motors, ensuring the winding current remains within design limits, the thermal overload protector is never unnecessarily triggered, and the motor reaches its full service life. Fitting a non-genuine substitute risks voiding any remaining warranty and can result in premature motor failure.
