Pump module has stopped
running.
Water leaks out of thermal
valve.
Filter housing leaks.
Pump module runs but
there is no fog coming out of
the nozzles.
Pump module runs but
there is no fog coming out of
the nozzles.
Transformer may be faulty.
Inlet water pressure has
dropped below 20 PSI.
Water is being restricted from
leaving the pump module and
it is over heating.
O-ring may be displaced or
broken.
Housing could be cracked.
There may be a large leak in
the high-pressure plumbing of
the system
The water pressure regulator
on the pump module may be
completely backed off.
Valve controller may be
restricting the flow of water to
any of the nozzles.
The low inlet water pressure
safety switch may not be
isolating the pump and
allowing it to run without water.
Check transformer line voltage and secondary
voltage.
Check inlet water pressure for low conditions.
You may have to monitor gauge for water
fluctuations.
Make sure enough nozzles are running to
permit enough water to flow from pump
module to keep it cool.
Inspect and replace if necessary.
If water freezes in housing it will be damaged.
You have loose or missing atomization
nozzles.
A reusable hose fitting or manifold connection
has come loose or has not been made
correctly.
The drain solenoid on the pump module is
stuck open allowing all the pumped water to
leave the system.
An auto drain valve on manifolds isn't closing,
verify that the sealing ball is seating properly.
Check pressure gauge = 1000 psi. Turn the
hand wheel on the regulator clockwise to
increase pressure to 1000 psi.
The pump must never be ran without any high
pressure water leaving the system, otherwise
the pump will overheat.
A very dangerous situation, the pump needs
water to run cool. Check the inlet water
supply and integrity of the pressure switch.
