Re: Starting Capacitor size for a 220v, 50Hz 2.5 kw water maker high pressure motor

The 48 mfd you measured is approximately 20% below the specified value for that motor.  Industry standards say a 10% deviation is OK.  I would not discount the capacitor as the culprit.  Also, try and rotate the motor from the cooling fan end by hand to see if the motor or pump is locked up – verify the power is off.  Good Luck.
