Troubleshooting
Low inlet pressure - 25 PSI or less:
• Dirty nominal and absolute filters are clogged with particulate - change filter bag and cartridge
• Low or no inlet water pressure - check to see that water charge pump is on and fresh water valve
to charge pump is open
• Empty water tank - fill tank with water
• Clogged or damaged impeller on pump - disassemble pump face and clean impeller or replace
with a new impeller
• Cracked water line allowing air to be sucked in - check and find any leaks and repair
• Three way valve set to wrong position - check valve position
• Low hydraulic fluid flow to charge pump - check hydraulic fluid level and flow
• Debris in water line from tank - flush or replace with new line
Low outlet pressure - in High Pressure system:
• Insufficient engine RPM - raise RPM of engine
• Warn or blown nozzles - change nozzles
• Oversized nozzles - refer to chart to correct nozzle pattern
• Leaks - hoses, fittings, nozzles, pump valves or seals - tighten or replace, check valves for heat
indicating internal bypass
• Worn or missing button seal between spray bar and shaft - replace with new button seal
• Air lock in fluid end - remove rupture disc assembly or side port fitting, engage pump and run up
to high RPM to remove air from the manifold
• Low inlet water pressure - change dirty water filters - cartridge & bag (also 20 micron in recycle
mode)
• Low or no inlet water pressure - check to see that water charge pump is on and valve to charge
pump is open
• Leaking packing - determine which is leaking and change, flush and replace
• Leaking or cracked valves - check face of manifold for heat to find leaking valve and replace or
rebuild
• Diverter valve (dump valve) cartridge leaking - remove return hose and check cartridge, if leaking
remove diffuser tube and replace cartridge
• By-pass valve cartridge leaking - remove diffuser tube and replace cartridge
• Leaking swivel seal - remove spent seal, check shaft nipple, clean thoroughly and replace with
new seal
• Cracked swivel or thru-shaft - remove shaft assembly and disassemble to inspect shaft and replace
if damaged or cracked on nipple end
Fluctuation or pulsing of 40K gauge or inlet pressure gauge:
• Valve may be pitted or cracked - remove valve and check seats for damage - replace or rebuild
• Leaking packing - determine which is leaking and change, flush and replace
