Troubleshooting
This control center was inspected and tested under
operating conditions before shipment from the factory.
In case of trouble, check the items listed below.
A. Disposer motor will not start and water
does not flow.
1. No incoming line power, turn line power on.
2. Electric disconnect switch is not ON. Turn electric
disconnect to ON position.
3. Electrical disconnect switch has been reactivated
and 30-second delay has not yet expired. Wait 30
seconds and try starting again.
4. Control circuit fuse FNA2 is blown. Replace fuse.
B. Disposer motor stops while grinding but water
continues to flow.
1. Control center wired for automatic shut-off. Press
start button. If disposer runs for 10 minutes then
shuts off, the automatic shutoff is active. If the
manual setting is desired, change as indicated in
the feature section.
2. Disposer is jammed. Press stop button and
follow directions for unjamming that were
supplied with the disposer.
3. Disposer motor overload protector has tripped.
Follow instruction in C1.
C. Disposer will not start but water flows.
1. Overload protector on the disposer may have
tripped. Press stop button. Locate red reset
button on front of disposer electrical cover.
Press to reset. If motor had been running, wait
five minutes for the motor and overload to cool
down before starting.
2. Disposer is jammed. Press stop button and
follow directions for unjamming that were
supplied with the disposer.
PERSONAL INJURY
• Allow only trained personnel to operate disposer.
• Use baffles and guarding to avoid splashing and
ejection of materials.
• Do not put fingers or hands into the disposer.
• When attempting to remove objects from a
disposer, use long-handled tongs or pliers.
• Turn power off before clearing a jam, removing
an object from the disposer or pressing the
red reset button.
PROPERTY DAMAGE
Use only an FNA2 replacement fuse. Using another
replacement fuse will result in product damage.
ELECTRICAL SHOCK/PROPERTY DAMAGE
• Troubleshooting other than what is recommended
in this section should only be performed by
qualified service personnel.
• Further troubleshooting performed by untrained
personnel could result in electric shock or damage
to the control center.
• All electrical checks must be performed by a
qualified professional.
D. Water flows constantly before start button
is pushed.
1. Water solenoid valve is installed backward.
Water flow should be in the direction of the arrow
on valve.
E. Water flow does not decrease to 1 GPM.
1. Incorrect solenoid valve combination
connections. See Water Solenoid Valve, page 7.
2. Incorrect trip point adjustment. See Current
Sensing Control Setup, page 8.
3. Food load is present in disposer.
F. Water flow does not increase.
1. Insufficient food load is present.
2. Incorrect trip point. See Current Sensing Control
Setup, page 8.
3. Solenoid valve wiring incorrect in panel.
4. More than two water solenoids wired into
system. System should have one solenoid with
a 1 GPM flow control and one solenoid with a
7 GPM flow control.
NOTE: Use shutoff valves to adjust water flow for
multiple trough or sink nozzles.
G. Overload trips frequently.
1. Do not overload disposer with excess amounts of
garbage and water (see disposer instructions for
recommended water flows).
