Symptom Details |
|
1 |
Power Cord
- Make sure that the power cord is plugged in and
receiving the proper voltage and current for your unit. |
|
2 |
Push-to-Reset Breaker - If
your unit has experienced an over current or extremely
high temperature, the button will pop out. To reset,
simply push the button in until it protrudes about 1/8"
and stays in. If the breaker pops out again when the
unit is used, call a service technician. |
|
3 |
Circuit
Breaker in House Panel -
Check your house breaker panel - if the circuit breaker
is off, you may have too many appliances utilizing that
circuit. For best results, your power unit should be on
a separate circuit. Try to remove some of the extra
circuit load by unplugging other devices. If the breaker
continues to cut off, call a service technician. |
|
4 |
Internal
Thermal Switch in Unit -
If your unit comes equipped with an internal thermal
switch and quits running, it may require 10 minutes to
cool off before resetting itself. |
|
5 |
Electrical
Wall Outlet Plug -
Sometimes the electric wiring from the house breaker
panel to the wall outlet plug can become loose or
broken. Plug a lamp or another electric appliance into
the outlet to assure that you are getting power. If not,
call your electrical contractor. |
|
6 |
Switch in
the Wall Inlet Stuck Off -
Plug your flexible hose into the other wall inlets - if
your unit functions normally then the problem lies in
the switch or remote control circuit to the inoperative
inlet valve. The bolts holding the micro-switch in the
inlet valve may have loosened allowing it to move out of
position. Remove the wall inlet face plate and tighten
the bolts or call a serviceman. |
|
7 |
Switch in
the Wall Inlet Stuck On -
Use your finger to roll the steel ball located in the
top of the neck in the inlet. Some foreign material may
have become lodged in the hole with the ball, preventing
it from moving into it's proper position.
Caution: if this procedure does not turn
your unit off, unplug the power cord and notify a
service technician. |
|
8 |
Remote
Control Wire - Broken -
Usually, if more than one wall inlet is inoperative, the
trouble is in the remote control wiring, and the wire is
either loose of broken, and should be tightened or
replaced. |
|
9 |
Remote
Control Wire - Shorted -
Unplug one of the remote control wires that is attached
to the side of the power unit - if the unit stops, it
indicates that the remote control wire is shorted or one
of the wall inlet switches is stuck in the ON position.
If the procedure for number 6 does not shut the unit off
and you cannot locate the short, notify a serviceman. If
the unit does not stop running when you unplug the
remote control wire - either the short is in the power
unit wiring or the relay is stuck .Refer to number 20.
Caution: Checking the wiring in
the power unit should only be attempted by a qualified
service technician. |
|
10 |
Flexible Hose - Plugged - If proper
airflow is not obtained through the house, remove the
hose from the vacuum inlet, then start the power unit by
activating the wall inlet switch. If the airflow at the
inlet is good, then this will normally indicate a
blockage in the hose of wand. If a blockage is in the
wand, it can be disassembled and cleaned. If there is a
blockage in the hose, the hose should first be laid out
straight, then with the house plugged into the inlet
valve and the power unit running, pick up the hose -
starting at the end furthest from the valve and gently
stretch about 2 feet of it at a time as you proceed
along the length of the hose toward the inlet valve. If
this does not clear the stoppage, then remove the hose
cuffs by unscrewing them, and switch them to the other
ends of the hose (these cuffs have left hand screw
threads so rotate them in a clockwise direction). After
this has been done replace the hose in the inlet valve
and with the power unit operating, repeat the process of
stretching the hose. If this fails to unclog the hose,
run (handle first) a screwdriver with at least a 3/4"
diameter handle through the hose. |
|
11 |
Tubing in Wall -
Clogged - Check the airflow at the power unit.
If the airflow is good here but not at locations further
from the power unit, your tubing is either clogged or
has broken open. If you cannot repair this, contact your
service man. If you turn the power unit on and leave the
inlet valve furthest from the power unit open and then
check the exhaust from the power unit, you can determine
whether you have a break in the tubing or whether the
tubing is clogged. If very little air is coming out of
the exhaust of the power unit, then it is probably an
obstruction in the tubing and not a break. |
|
12 |
Dirt Canister
Lid - Off - On the models with lift off dirt
canister lids, the lid must be replaced squarely on top
of the canister or it will allow a vacuum leak. |
|
13 |
Dirt Canister
Gasket - Loose i If the dirt canister gasket has
been pulled loose, it will allow a vacuum leak. The
gasket may be reattached with contact cement or any of
the so called 'super glues'. |
|
14 |
Outside Exhaust
- Blocked - Check the exhaust system by removing
the tubing from the motor blower exhaust and comparing
the airflow at this point versus the airflow reaching
the outside. If blockage id detected and cannot be
removed, contact your service technician. |
|
15 |
Dirt Canister -
Not Attached - If the dirt canister latches
(some models only) are not properly closed, it will
cause an air leak along the gasket and reduce your
cleaning ability. |
|
16 |
Another Wall
Inlet Door - Open - Check all the inlet valves
to make sure that only one inlet is in use at a time.
Attempting to clean from two or more inlets at a time
will reduce the airflow below the level required to deep
clean your carpets. |
|
17 |
Motor Protection
Screen - Clogged - This usually occurs due to
allowing the dirt canister to overfill, or a broken
filter bag (some models). |
|
18 |
Relay Stuck - On
- Refer to #9. If after using the procedures described
it appears the relay is sticking on, unplug the power
cord to cut off all electricity to the power unit.
Caution: Checking the wiring in the power unit should
only be attempted by a qualified service technician. |
|
21 |
Relay Stuck -
Off - If the procedures described in #1, 2, 3,
4, 5, 6 or 7, do not correct the power unit not
starting, then it could be a malfunction of the relay,
the low voltage transformer could be burned out, or
there could be a loose wire in the power unit. If you
suspect a malfunction in the power unit, contact your
service technician. |
|
22 |
Transformer -
Burned Out - Refer to #21 |
|
23 |
Loose Wire in
the Power Unit - Refer to #21 |
|
24 |
A Hose Plugged
Into Another Inlet Valve - Cleaning from more
than one inlet at a time will reduce the airflow to less
than is required to deep clean your carpets. |
|
25 |
P.C. Board Relay
Stuck On - Refer to #9. If after using the
procedure described in #8 it appears that the relay is
sticking on, unplug the power cord to cut off all
electricity to the power unit. Caution: Checking the
wiring in the power unit should only be attempted by a
qualified service technician. |
|
26 |
P.C. Board
Transformer Burned Out - If the procedures
described in #1, 2, 3, 4, 5, 6 or 7 do not correct the
power unit not starting then it could be a malfunction
of the relay, the low voltage transformer could be
burned out, or there could be a loose wire in the power
unit. If you suspect a malfunction in the power unit,
contact your service technician. |
|
27 |
LED Light
- Some units have an LED light at the unit. If the LED
light is not on, refer to #5. If you have power at the
unit but LED light is off, contact your local service
technician. |
Problem: Little
or No
Suction Power |
|
 |
|
|
|
|
| |
Problem:
The
Unit
Will
Not
Start
|
|
1)
Check
the circuit breaker on your electrical panel.
2)
Check the circuit breaker of the unit.
3)
Check the 24 volt circuit:
To check the 24 volt circuit, proceed as
follow;
Establish the contact between the two ports of a wall
mounted air inlet valve with a piece of metal (ex. coin). If
the system starts, the suction hose is defective.
If
the system does not start check the 24 volt circuit on the
unit; Establish the contact between the two screws of the 24
volts circuit plate using a piece of metal
(ex.
Screw driver) . If the unit starts, the 24 volt wire is
either cut OR unplugged from one of the wall mounted air
inlet valves.
If the system still do not start after steps
1, 2 and 3, the printed circuit is defective.
Call your dealer.
|
|
| |
|
Problem:
The
Unit
Will
Not
Stop
1)
Check
the 24 volts circuit as follows:
Disconnect one of the two 24 volt wires on the unit . If the
unit stops, the two wires are in contact somewhere in the
circuit OR a wall mounted air inlet valve is defective.
If
the unit does not stop, the printed circuit is defective.
Call your dealer.
NOTE:- If you notice a vibration coming from the motor, call
your dealer.

|
Problem:
Crack In PVC Pipe |
This is
another common cause of suction loss. This problem may occur
when someone in
the attic area steps on the pipe by accident. |
|
 |
1) Cut out the defective
pipe section.
2) Slide over the
existing pipe a pair of slip couplings.
3) Insert the new pipe
section in position.
4) Apply PVC glue and
slide back into position the two slip couplings and
your done!
Helpful Tip
Practice the procedure several times without the glue so
that when you apply the glue, this procedure will be problem
free. |
