Troubleshooting
PROBLEM
Loss of solution pump
pressure.
With the cleaning tool
open, the solution
pressure gauge reads
below the normal
operating pressure.
Loss of solution
volume at cleaning
tool orifice. Solution
gauge reads normal.
CAUSE
Water supply is turned off or the float
valve is stuck or improperly adjusted.
Solution pump inlet supply line is
plugged or drawing air.
Improper engine speed
Pressure regulator o-ring is dry.
Pressure regulator has worn o-ring
Pressure regulator is dirty, stuck open,
or improperly adjusted.
Low pump volume. (Measure the
amount of water being returned to the
water box from the pressure regulator. It
should fill a gallon container about every
17 seconds).
Defective solution pressure gauge.
Orifice (spray nozzle) in the cleaning
tool is worn, defective, or wrong size.
Debris clogging water lines or water inlet
disconnect.
Belt loose or broken
Loss of pump prime
Plugged orifice and/or screen in the
cleaning tool.
Internal block between the pressure
regulator manifold and the solution
manifold; or the solution screen is
clogged
Outlet check valve is plugged
Defective quick-connect on one or more
of the solution pressure hoses.
Cleaning tool valve is malfunctioning.
Hose inner lining is constricted.

SOLUTION
Turn the water supply on or up. Check for kinks
in the water supply hose. Examine the float valve
and adjust or replace.
Examine the water inlet strainer inside the water
box. Remove accumulated debris and replace if
required. Check for suction leaks and loose
clamps or fittings. Tighten any loose fittings or
clamps. Replace any ruptured hose(s).
Using a tachometer, check the engine speed.
Full throttle engine speed is 2850 RPM. Idle
engine speed is 1200 RPM. Refer to the "engine
speed" section for instructions on how to re-
adjust.
Lubricate o-ring, using o-ring lubricant P/N
86265430.
Check o-ring. If necessary, replace.
Clean or repair regulator. Adjust to working
pressure. Lubricate o-ring, using o-ring lubricant
P/N 86265430.
Examine the check valves, plunger cups, and
cylinder head on the solution pump. Repair,
whenever required (refer to the solution pump
service manual).
Replace gauge
Replace Nozzle or change nozzle size.
Clean or replace as needed.
Re-tension or replace as needed.
Manually prime solution pump.
Unplug or replace orifice and/or screen
Inspect all lines, remove accumulated debris
which is blocking proper flow. Replace any
defective hoses. Remove, inspect, and clean the
solution screen. De-scale unit and install a water
softener, if necessary.
Examine the check valve, remove any debris
Replace defective quick-connect(s) on solution
pressure hose(s).
Repair or replace valve.
Remove restriction or replace hose.
