The pump capacitator
may be damaged. Contact a qualified service technician to
confirm the capacitator is damaged.
The pump shaft may
be locked or jammed. Check for blockages that may be
causing the pump to seize:
1. Turn the power off.
2. Rotate the fan and ensure it spins
freely with no resistance.
3. Remove pump casing and check for objects
jammed between moving components.
It is recommended to call a pump
technician or licensed professional.
The electronic card in
the pressure controller
may be broken.
* Only applicable if
a pressure controller
has been installed.
If a pressure controller has been installed,
the electronic card in the controller may
need to be removed and replaced with
a new card, or a new unit entirely.
This should only be done by
a qualified electrician.
Voltage failure. Check with a licensed electrical
contractor to ensure voltage is
correctly supplying the unit. Refer
electrical data in manual.
The pump will
not start, but is
making noise. The pump may
be jammed. If there is a humming sound coming from
the pump motor, this may be due to
debris or damage to the impellers being
blocked and no longer turning or damage
due to incorrect pump selection.
1. Check pump internals for debris.
2. Check system pump requirement.
This should only be done by
a qualified electrician.
