Pump “Error” or
RED LED signal
appears on the
Pressure Controller.
* Only applicable if
application is using a
pressure controller.
The pump may have
failed to prime.
Check there is water in the tank.
The pressure controller is protecting
the pump against loss of prime.
1. Simply press the “Restart” button.
2. If the system fails again, the unit is
detecting that there is air in the suction
pipe and has shut down to protect
the pump from long term damage.
3. Check the pressure gauge on the side
of the pressure control to determine if
that model pump is operating correctly
when referencing its pump curve.
4. Bleed air from system while the suction
line is connected to the pump.
a) Above ground tank: Remove priming
plug on pump casing. Allow water
to flow through via gravity until
all air has been expelled.
b) Below ground tank: Ensure foot
valve is installed, fill up suction line
and casing from discharge point.
5. Activate all appliances/outlets
sequentially from the nearest to the
furthest outlet. Repeat if necessary.
6. If problem persists, please contact
the Reece branch where the
pump was purchased from.
Refer to page 16 for more information
on priming the pump.
The suction pipe diameter may be too
small and causing high pressure loss
or cavitation. Increase the pipe size to
an internal diameter that is the same
size as the suction inlet, or larger.
Note:
This means for a 25mm inlet pump
a 32mm PN12.5 Poly Pipe must be used.
There may be debris caught within the first
impeller not allowing pressure to be created:
1. Disassemble pipework and pump housing.
2. Clean impellers.
It is recommended to call a pump
technician or licensed professional.
The Digital Water
Switching Unit has
gone into “loss of
prime” (no water
is being delivered
to pump).
* Only applicable if
application is using a
digital water switch.
The pump has failed
to prime, no water
is being detected.
The system may have a large pipe
network to charge and the pump is
running high flow with no pressure.
1. Close the isolating valve on the
discharge line to almost 90% closed.
2. Restart to ensure the pump has head
pressure and fills the line slowly.
The valve on or
between tank and
switching unit inlet
may be closed.
You will need to reprime the pump
and reset the water switch.
1. Open the isolation valve on the suction line.
2. Bleed air from system while the suction
line is connected to the pump.
a) Above ground tank: Remove
priming plug on pump casing. Allow
water to flow through via gravity
until all air has been expelled.
b) Below ground tank: Ensure foot
valve is installed, fill up suction line
and casing from discharge point.
3. Activate all appliances/outlets
sequentially from the nearest to the
furthest outlet. Repeat if necessary.
4. Reset the switching unit.
Refer to page 16 for more information
on priming the pump.
The mesh filter in
the water switching
unit is blocked.
1. Switch off power to the unit.
2. Isolate the water lines and remove
the pump barrel union.
3. Inspect/clean/replace the
switching unit mesh filter.
