TROUBLESHOOTING:
WATER PUMP
PROBLEM
CAUSE
SOLUTION
Loss of solution volume at
cleaning tool orifice:
Solution
pressure gauge reads normal.
Hose inner lining is constricted.
Remove restriction or replace hose.
Air leak in chemical supply line,
priming valve or metering
valve.
Check for air leaks. Replace faulty
parts.
Defective quick-connect on one
or more of the high pressure
hoses.
Replace defective quick-connects(s) on
high pressure hoses(s).
Loss of solution pump
pressure:
With the cleaning
tool open, the solution pressure
gauge reads below the normal
operating pressure.
Water supply is turned off or the
float valve is stuck.
Turn the water supply on or up. Check
for kinks in the water supply hose.
Examine the float or replace.
Solution pump inlet supply line
is plugged or drawing air.
Examine the water inlet filter 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).
Improper engine speed
Using a tachometer, check the engine
speed. Full throttle engine speed is
3000 RPM. Idle engine speed is 1500
RPM. Refer to the “engine speed”
section for instructions on how to re-
adjust.
Pressure regulator o-rings are
dry.
Lubricate o-rings, using o-ring
lubricant
Pressure regulator has worn o-
rings
Check o-rings. If necessary, replace.
Pressure regulator is dirty, stuck
open, or improperly adjusted.
Clean or repair regulator. Adjust to
working pressure. Lubricate o-rings,
using o-ring lubricant Part
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 17.6 seconds).
Examine the check valves, plunger
cups, and cylinder head on the water
pump. Repair, whenever required
(refer to the water pump service
manual).
Defective water pressure gauge. Replace gauge
Orifice (spray nozzle) in the
cleaning tool is worn, defective,
or wrong size.
Replace Nozzle or change nozzle size.
Debris clogging water lines or
water inlet disconnect.
Clean or replace as needed.
Belts loose or broken
Re-tension or replace as needed.
Loss of pump prime
Manually prime water pump.
