5.1 - Vacuum Troubleshooting
Vacuum is not turning on.
Possible Cause
Solution
Vacuum may not be get-
ting 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 ex-
changed 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, re-
connect 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 ma-
chine.
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 reg-
ularly 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 mo-
tor. To avoid repeat prob-
lem, 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 ex-
changed 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
disconnected wires. Re-at-
tach or replace wires.
Pump runs but there is no spray.
Possible Causes
Solutions
Blockage or kink some-
where in the line.
See chart on page 4 of
this
document
to diagnose the
location of the blockage.
