5.1 - Vacuum Troubleshooting
Vacuum is not turning on.
Possible Cause
Solution
Vacuum may not be getting
power.
Check the electrical con-
nections and the switch.
Look for loose or damaged
wires.
To check the switch:
Unbolt the switch plate.
Take a picture of the layout
of the wires or tagging the
wires for future reference.
Switch the wires from
the vacuum switch with
the wires from either the
pump or heater switch.
Turn on the pump or heater
switch (whichever one you
exchanged wires with). If
the vacuum turns on, then
you know the vacuum
switch is bad.
Vacuum is not producing suction.
Possible Causes
Solutions
Recovery tank is full.
Empty the recovery tank.
If the vacuum exhausts but
there is no suction, then
the hose from the recovery
tank to the vacuum motor
is disconnected.
Open the machine and
find the hose running from
the recovery tank to the
vacuum motor. Check if
it is disconnected. If so,
reconnect it. If it has a leak,
replace the hose (Part #
PH627 if 1.5”, PH628 if
2”).
Vacuum hose blockage
(if there is no suction or
exhaust).
Check for blockage in
the hose, starting from
the cleaning tool to the
machine.
Clogged filter in vacuum
tank.
Clean out filter regularly.
Drain valve/cap is loose
and is causing air leakage.
Tighten the drain valve/cap.
Hose cuffs are loose and
causing air leakage.
Tighten all hose cuffs
regularly as may loosen
over time. Use a glue to
prevent cuffs from coming
loose (optional).
Lid on tank is loose and is
causing air leakage.
Make sure the lid is tight.
Vacuum blows water out the exhaust.
Possible Causes
Solutions
Foam building up in the
recovery tank.
Use a defoaming solution
in the recovery tank.
There is a loud grinding noise coming from the
vacuum.
Possible Cause
Solution
Debris has been sucked
into the vacuum motor
chamber. Usually results
from dry vacuuming.
Replace the vacuum motor.
To avoid repeat problem,
DO NOT dry vacuum with
your extractor.

5.2 - Pump Troubleshooting
Pump doesn’t turn on.
Possible Causes
Solutions
Bad switch at control
panel.
Unbolt the switch plate.
We recommend taking a
picture of the layout of the
wires or tagging the wires
for future reference. Switch
the wires from the pump
switch with the wires from
either the vacuum or heater
switch. Turn on the vacuum
or heater switch (whichever
one you exchanged wires
with). If the pump turns on,
the pump switch is bad.
Loose or disconnected
wire.
Disconnect the power cord
from the electrical outlet.
Open up the machine and
look for any loose or dis-
connected wires. Re-attach
or replace wires.
