Jandy ePump 2.7 THP Variable Speed Pool Pump with Digital Control MECH-06 Error Fix: Capacitor Failure — Motor Hums But Will Not Start

Error code MECH-06 on the Jandy ePump 2.7 THP Variable Speed Pool Pump with Digital Control means: Capacitor Failure — Motor Hums But Will Not Start. The pump motor hums audibly but does not spin — the run capacitor has failed or is out of specification; the capacitor provides the electrical phase shift needed to start and run the motor; a failed capacitor prevents the motor from developing starting torque; the motor hums because it is energized but cannot rotate; turn off power immediately to prevent winding damage from locked-rotor current; test the capacitor with a multimeter that has a capacitance (μF) measurement function — the value should be within ±10% of the rating printed on the capacitor; replace with an exact match for μF and voltage rating

The most successful fix is "Test and Replace Run Capacitor with Exact Match" (medium difficulty, ~45 minutes). Estimated DIY cost: $15-$30. HomeMD has 2 community-ranked fixes for this error.
