The emergency stop (Q) is
engaged.
Disengage the emergency stop (Q).
The air supply is inadequate.
Make sure the air compressor is capable of supplying
the minimum air flow requirement for your system (see
Technical Specifications, page 66
). Make sure the air inlet
pressure gauge reads 100-175 psi (6.8–12 bar, 0.68–1.2
MPa). If the gauge does not read 100–175 psi, check the air
compressor for proper setup. Make sure the air inlet filters
are clean, and replace if necessary.

1. Make sure all fitting connections are tight. Check the inlet
water pressure regulator for proper flow direction installation
see
, or
. Check the
inlet water pressure regulator screen filter for debris, clean if
possible. If no flow can pass through the regulator, replace it.
The water pump air regulator
is malfunctioning.
Disengage the blast control switch (B). Adjust the pump inlet
air pressure regulator until the pump air pressure regulator
gauge reads 100 psi (6.9 bar, 0.69 MPa). If you are unable
to attain this setting, check the air inlet filters and make sure
the supply air pressure is greater than or equal to 100 psi. If
the above steps do not resolve issue, replace the pump air
pressure regulator.
The water pump is
malfunctioning.
Rotate 3-way selector valve to the OFF position. Open the
rinse valve and make sure the pump cycles, and water flows
from the rinse hose. Close the rinse valve and verify that the
pump stalls. If the pump continues, creeps, or will not prime,
refer to manual 333397 for pump service.
The pop-up cannot seal.
Make sure the pop-up is clean and free of debris in the o-ring
sealing area. Check for proper pop-up alignment in the closed
position (there should be no gaps between the o-ring and the
pop-up). Remove the o-ring and make sure the o-ring gland
is clear of debris. Replace the o-ring and/or pop-up if worn.
Unable to fill or
pressurize the pot
with water.
The water pressure regulator
is malfunctioning.
Adjust the water pressure regulator until the pot pressure
gauge reads 185 psi (12.75 bar, 1.275 MPa). If this
adjustment is not possible, service the water pressure
regulator (see manual 309474).
