Material water consistency Inlet water pressure is fluctuating
below the regulator-set pressure. The water pressure regulator (DD) reduces
the pressure at the water metering valve
(DF) to a constant value. Adjust the water
pressure regulator (DD) so the pressure is
less than the lowest pressure possible from
water supply.
Water pressure and flow is
constant, but there is less dry
material entering mix tube. There is not enough dry material in the
hopper. Add more dry material to the hopper,
and keep adding dry material to maintain the
level as close to the hopper grate as
possible.
The material dosing auger shaft (FD) is dirty
or worn and needs to be cleaned or
replaced.
There is a debris in the water
control assembly (D). Verify the water inlet screen (DCC) is in
place and that it is clean.
Disassemble the water assembly and clean
any debris.
Clean debris from water dosing port (FCC).
Water does not turn on, low
flow, or water does not turn off. Solenoid damaged or clogged with
debris. Clean or replace water control solenoid (DE).
Incorrect solenoid installed. The solenoid must be “normally closed” type.
Use only genuine Graco replacement parts.
There is debris in the water control
assembly (D). Verify the water inlet screen (DCC) is in
place and that it is clean.
Disassemble the water control
assembly (D) and clean any
debris. Clean debris from water dosing port (FCC).
