Trouble Shooting (cont.)
2. If the motor unit still does not turn on, advance temperature to 104º F/40º C. If
the heating light is on and the pump is not running, unplug the unit for a few
hours then repeat step one. If the motor unit still fails to start, disconnect the
motor unit per instructions and take the motor unit to your dealer.
Note: if you regularly need to unplug the unit to allow the jets to operate, you
are having a low voltage problem. Make sure your motor unit is not connected to
an extension cord and that the circuit you are using does not have another
major appliance connected to it. Poor household wiring and/or connections can
cause a low voltage situation.
Problem: No LED temperature display.
Cause: Loss of power to the motor unit.
Solution:
1. Test the GFCI on the power supply.
2. If the GFCI is functioning, take the motor unit to your dealer.
3. If the GFCI is not tripping and the LED temperature display is flashing, the water is
too hot. To allow the high limit to reset, let the tub cool to below 100º F/40º C then
repeat #1.
4. If the above happens repeatedly or the motor unit does not reset, take the motor unit
to your dealer.
Problem: Weak jets.
Cause: Air or a solid obstruction in the plumbing. If the tub was just filled, it is probably
air.
Solution:
1. Check to see that the jets are turned on.
2. Make sure the water height is at least 2 inches above the top of the uppermost jets.
3. Verify that no plugs or other coverings are over the suction inlets in the tub. (The
suction inlets are the lower fittings.)
4. Turn the jets on and off several times to clear the air.
Problem: All jets lost power while operating.
Cause: Obstruction in the plumbing.
Solution:
1. Remove the filter. See the instructions on page 17.
2. Check to see if the suction strainers are in place and free of debris.
3. If these are clean and you still have weak jets:
A. Unplug the motor unit.
B. Drain the tub.
C. Disconnect the hoses.
D. Separate the motor unit from the tub.
E. Inspect the plumbing exposed by opening the unions for blocking materials
such as hair, leaves, string, plastic bags, etc.
F. Clean and flush the motor unit with full pressure from a garden hose placed
in the top large hose connector of the motor unit.
G. Re-assemble and try again.
4. If no blocking objects were found and there is still no power, debris is probably
lodged inside the pump. Take the motor unit to your dealer.
