Troubleshooting
Water pressure is too high
If the value on the prefilter water-pressure gauge is higher than 7.93 bar or 792.90 kPa (115 psi), the water
pressure is too high. If the value on either water-pressure gauge is more than 8.62 bar or 861.84 kPA (125 psi),
contact a Hypertherm Technical Service Associate for assistance.
The pump's low-pressure water parts are rated for a maximum pressure of 8.62 bar or 861.84 kPA (125 psi). In
environments with high supply water pressure, the boost pump can increase the water pressure to more than the
maximum. This can damage the filters and other parts.
A secondary bypass relief valve before the filter assembly reduces the risk of damage. This relief valve is set
to 8.27 bar/827.37 kPa (120 psi) at the factory and should not be adjusted.
Possible cause Solution
The boost pump is not needed.
If the value on the prefilter water–pressure gauge is
higher than 4.83 bar or 482.63 kPa (70 psi), turn OFF
the boost pump.
1. In the electrical cabinet, turn the switch on the boost
pump motor contactor to 0.
2. Turn OFF boost fault monitoring.
a. On the operator interface, go to the Settings
screen. Refer to the
Settings screen section,
which begins on page 54.
b. Touch the pump settings symbol.
c. Touch System Settings.
d. Touch the Boost Fault Monitor status indicator.
Green shows enabled status. Red shows
disabled status.
The boost pump bypass relief valve is not
adjusted properly.
Refer to
Adjust the boost pump pressure on page 201.
A water filter is clogged. Replace the water filters.
