Failure modes to watch for
Every guide in the Flow International Flow Mach 200 / 500 / 700 library lists the candidate root causes its procedure rules out. These are the distinct failure modes we've documented so far, a useful starting point if you don't yet know which specific alarm or symptom you're chasing.
Abrasive hopper empty or bridged preventing flow
Metering orifice clogged with clumped wet garnet
Abrasive feed line kinked or blocked
Worn metering orifice bore enlarging and causing inconsistent flow rate
Orifice jewel erosion from cumulative water passage (typical life 40 to 100 hours with good water quality)
Focusing tube erosion from abrasive garnet stream
Contaminants or scale in the ultra-high-pressure water stream damaging the orifice
Incorrect jewel seating allowing micro-movement and accelerated wear

How to fix abrasive feed interruption on a Flow Mach 200 / 500 / 700 waterjet
Abrasive stoppages are usually a clogged abrasive line, empty hopper, or a worn or blocked metering orifice. Check the hopper level first, then inspect the abrasive line from hopper to nozzle.
How to troubleshoot low intensifier pump pressure on a Flow Mach 200 / 500 / 700 waterjet
Low intensifier output pressure is usually worn high-pressure seals, check valves, or a damaged intensifier cylinder. Inspect the check valve cartridges and HP seals before condemning the cylinder.
How to diagnose and replace a worn orifice or nozzle on a Flow Mach 200 / 500 / 700 waterjet
A widening kerf, taper on cut parts, or reduced cutting speed nearly always means the orifice jewel or focusing nozzle is worn. Replace both as a set when cut quality degrades.
