Possible cause Corrective action
Ensure that the power meets Technical specifications.
If the power supply is adequate, then switch off the
power first, open the controller housing and check:
— the fuses are not blown
— wires in screw terminals #30, #31, #32 are not loose
The system requires clean power supply compliant with
the Technical specifications.
Check for brownout, overvoltage, power surges.
Check if the permeate tank is full, or if the float switch has
stuck in the upward position. Check that the permeate
pipeline is not blocked or shut off with a valve.
Push START button to see if it is manually stopped. If
nothing happens, then (remove the power first!) open
the electrical panel and check that Stop terminals are
connected with a jumper wire.
Thermal protection switch (built-in the motor junction
box) may trip due to pump stalling, jamming, or
inadequate voltage. It will release after cooling down.
Another possibility is a loose wire in the controller
terminal block or in the electrical panel (remove power
before accessing the electrical parts!)
Fill the system completely with water. One way to do this
is to enter controller settings and temporarily set 1.1 High
pressure pump delay to 255 seconds, then revert back
after the air bubbles disappear.
Avoid using long runs of small diameter pipes. Check that
there are no sharp bends if using a flexible hose.
Check the filter cartridge and replace if necessary.
