[APD] pump motor gets hot
If the pump is not blocked & is generating a good flow of water, there
should be enough torque on the electric motor to generate the back EMF
necessary to prevent excessive current flow, which is the root cause of
heating. Make sure the water flow through the pump is occurring. Do not
operate a blocked pump; it will overheat irrespective of whether its a
centrifugal pump or not.
Perhaps the pump coupling is loose?
If the motor heats even with a decent load, then it may have an internal
short or was wired incorrectly or missing a fan in this configuration.
Take it back!!!
