Fault
Possible Cause
Remedy
4.The pump is running continuously.
a) The pump cannot deliver the
set pressure. The EZ Boost
controller or the sensor is
defective.
• Try to lower the pressure setting,
see section 7.2.3. Note that the pump
may run for about 15 to 20 seconds
before it stops.
• Check that the control indicator LED
is flashing.
• Check that the pipe end of the sensor
is not blocked. If so, remove the
blockage.
• Try to stop the pump by means of the
on/off button. If this is not possible,
the EZ Boost controller is defective.
Replace the EZ Boost controller.
• Refer to fault 13 to troubleshoot the
pressure sensor.
5. The EZ Boost controller indicates
“No contact to pump”.
a) The pump cable is longer than 650 feet.
b) Cable breakage
c) Cross communication with adjacent EZ
Boost controller.
d) The EZ Boost controller communication
part is defective.
e) The BMQE motor communication
part is defective.
• Reduce the length of the pump cable.
• Switch off the main power supply to
the EZ Boost controller. Switch on the
main power supply again. The pump is
now connected direct to the main
power supply without interference
from the EZ Boost controller.
Does the motor start?
Yes:
The cable is OK. Go to point d).
No:
Switch off the mains supply again.
Remove cable and cable plug from the
motor and ohm out cable including
plug.
Is the cable OK?
Yes:
The motor is defective. Replace the
motor.
No:
Replace the cable.
If another EZ Boost controller is installed:
• If pump cables run parallel to each other
physically separate them by 12 - 14
inches (305-355 mm) or rewire using
shielded cable.
Are the three EZ Boost controller supply
board LED’s in pos. 2, 3 and 4 on and is the
control indicator LED flashing? See section
7.3.3.
Yes:
The mains supply is OK.
Is the LED “No contact to pump” of the
new EZ Boost controller also on?
Yes:
The EZ Boost controller is OK. Go to
point e).
No:
The EZ Boost controller which was
removed is defective.
• As a consequence of the above
mentioned checks, replace the BMQE
motor.
