I wasted a lot of time following the expert advice to repair my unit by
taking the cover off of the main unit and using compressed air to blow
out the lines. The problem turned out to be in the lower panel of the
handle (4 screws to remove). The heater is a large block of aluminum
with a stainless cover held on by screws. The lower nozzle of the
heater was blocked by water/soap reacting with the aluminum while in
storage. Blowing out the lines as recommended with air compressor just
warped the stainless cover resulting in time spent flattening this back
I would recommend the following steps:
1. Make sure that fluid levels are up in both the supply water bladder and the soap dispenser.
2. Pry off the left side access cover and ensure the pump drive belt is
still in position. Switch the unit on and see that the pump is
3. With the unit plugged in and the handle laying flat
on the floor (using the foot release lever) , remove the clear bezzel
over the red impeller, switch the unit on, and pull the trigger for
soap. Liquid stream should shoot straight up past the impeller. If not
the lines are plugged somewhere.
4. Unplug the electric power. Remove the four screws and remove the lower handle access cover (with the red light in it).
5. All the fluid lines are clear plastic so you can identify which have fluid movement.
6. Disconnect the line from the soap activation switch (pliers on the
squeeze hose clamp) feeding the heater (large aluminum block). Blow air
(with your mouth NOT the air compressor) into this line and see if
fluid movement is observed in the clear plastic lines. A little
tentative about soap in your mouth, use a turkey baster filled with
water). I saw no movement of liquid. Nozzle exiting the heater blocked.
7. Remove this hose and use a small drill bit to twist the debris
loose. You may elect to remove the heater shinny cover for better
access. Gaskets are reusable. Blow thru the hoses again to assure
8. Button unit up.
9. With the clear bezel
off and the red rotor exposed, plug unit in, soap and water supplies in
place, switch on power and pull soap trigger. Should see vertical
stream. Mine was about 5 inches initially then jumped to about 10
inches high. Knew blockage was cleared.
10. During shampoo
operation if soap stops (red impeller stops spinning) first check fluid
levels and fill. That doesn't work, I unscrewed the clear bezel and
pulled the soap trigger with the unit switched on. Less than a second
vertical stream appeared every time.
11. Now you know how to fix and achieve continuous operation.
12. The unit must be thorougly cleaned before putting it away for
storage to prevent the reoccurance of the blockage in the heater. After
following the manufacturer's instructions, by flushing (operating the
unit) with clear water in the bladder and the soap dispenser, I did one
final thing. By removing the fresh water storage/collection plastic
container, a black round fitting is exposed that channels the water
from the bladder into the spray system. I used a length of automotive
heater hose that was the same diameter as the seal on this fitting
(turkey baster with bulb off will work) and blew hard while the unit
was switched on and the clear bezel was off. One last big blast of
water spewed from the unit. This cleared all the lines from the bladder
through the pump, switch, and heater and blows it out just prior to the
This is long but specific.
Not so technical, take each step as presented.
