TROUBLESHOOTING – DIAGNOSING SPECIFIC PROBLEMS
PROBLEM
POSSIBLE CAUSE
REMEDY
1. The pump does
not run when push
button is pressed.
Green LED does
not illuminate.
A. No power at electrical outlet
B. You’ve plugged the controller
into an electrical outlet con-
trolled by a wall switch, (such
as the outlet under many
kitchen sinks that controls the
garbage disposal.)
• Plug the controller into a “hot”
outlet
2. The water is not
hot enough.
A. Pump was installed with
water flow going in the wrong
direction
B. There is something in the piping
that has blocked the flow of water
• Check the arrows on the pump
casing to make sure they point in
the correct direction (see page 2)
• Check the piping for obstruc-
tion
3. There is hot water
at the cold water
tap.
A. The water temperature sensor
is loose or dislodged
B. The temperature sensitivity set-
ting now in place is too low, so
the pump is not shutting down
soon enough
• Check the connection of the
water temperature sensor to
make sure it is firmly attached
to the plug and casing
• Call 1-401-942-8000 for reset
information
4. Water is not hot
enough when
pump shuts down.
A. The temperature sensitivity set-
ting now in place is too high,
and the pump is turning itself
off too soon
• Call 1-401-942-8000 for reset
information
5. There is hot water
in the cold water
lines only
A. The pump is installed back-
wards
• Reinstall the pump correctly
C. Power cord is not secured to
pump
D. Wire to push button is not con-
nected well
E. The temperature setting is
already sensing “hot” water so
the pump is not being activated
• Call 1-401-942-8000 to reset
sensitivity setting
• Shut off power, then make sure
wires have good contact
