TROUBLESHOOTING
SYMPTOM
POSSIBLE CAUSE(S)
CORRECTIVE ACTION
Motor will not run
Fuse is blown or circuit breaker tripped
DISCONNECT POWER; Replace fuse or reset circuit breaker.
Power cord not plugged in
Plug into 115 Volt grounded outlet.
Motor runs hot and
Voltage is too low
Check voltage being supplied to pump.

Impeller not moving freely
Check that impeller moves freely and is not clogged.

Clogged water filter
Stop pump, shut off water, and change filter cartridge. Filter should be
installed on discharge side of pump.
Discharge valve closed
Open valve.
Pipe size too small
Re-pipe using pipe of the same size as suction and discharge ports on pump.

Clean impeller.

Pressure Drop/No Flow:
Normally, when the pump
starts, it will very quickly generate pressure and sense
flow. If there is no flow and the pressure does not rise, it
senses a “no water” condition. It can also sense this dur-
ing operation if the water supply to the pump fails. To
protect the pump from running dry:
• 15 seconds after it detects “no water”, the pump will
stop operating,
• The ‘PUMP ON’ LED will go out, and
• The ‘WATER FAILURE’ LED will begin flashing.
Restart:
Make sure that the suction line is not obstruct-
ed, and that it is connected to a water source.
• Press and release the ‘RESET’ button.
• The ‘PUMP ON’ LED should light up, and
• The ‘WATER FAILURE’ LED should stop flashing.
If flow is adequate, the pump will operate until 15
seconds after it reaches the set-point pressure and
the flow stops.
High Temperature:
When the water temperature inside
the pump reaches 158°F (70°C),
• The pump will stop operating,
• The ‘PUMP ON’ LED will go out, and
• The ‘TEMPERATURE FAILURE’ LED will begin flashing.
Restart:
Wait 20 minutes to let the water temperature
drop below 104°F (40°C):
• Make sure that the pump is supplied with water and
that the flow is unobstructed.
• Press and release the ‘RESET’ button.
• The ‘PUMP ON’ LED should light up, and
• The ‘TEMPERATURE FAILURE’ LED should stop
flashing.
• If not, let it cool some more and retry
NOTE:
If the pump continues to run hot, shut it off
and call Flotec Customer Service at 1-800-365-6832.
LUBRICATION
The motor is lubricated at the factory for the life of
the bearings. The pump seal is water cooled and self
lubricating.
PUMP SERVICE
Hazardous voltage.
Can shock, burn, or
cause death. Unplug the pump and controller before ser-
vicing them. Do not handle the pump or controller or
attempt to work on the pump with wet hands or while
standing on a wet or damp floor.
The motor has an auto-reset thermal overload protector.
If the motor overheats, the overload will cut off the
power to prevent damage and will reset after the motor
cools. If the overload trips repeatedly, check the pump
for the cause (low voltage, a clogged impeller, etc.).
