5
Over pressure
This code displays if the pipe pressure reaches 99% of the
maximum allowable pressure for the Transducer. Once the
pressure reduces to less than 96% of the max pressure, the VSD
will revert to normal operation.
6
Dropped Phase
When the input is three phase power, this code indicates that the
power supply has dropped from 3 Phase to 2 or 1 phase. Contact
your power supplier.
7
Overload
This code shows when current draw (Amps) are too high, Contact a
licenced Electrician to inspect and troubleshoot.
8
Over-current or
short circuit
This code shows when the motor short circuits or has seized or has
some other problem to cause high current-draw (high Amperage
draw) Contact a licenced Electrician to inspect and troubleshoot.
OTHER PROBLEMS & POSSIBLE CAUSES
5.1 Light Flashes “Failure”
This normally indicates that the pump has no water, either because the tank is empty or the pump has “lost prime” =
run dry. The pump is fitted with an AUTOMATIC RESTART so it will attempt to re-start itself several times. This is
normal, it does not mean the pump is faulty. Refer to point 3.9.2 the button instructions. Check your water supply,
is the tank empty? Does the suction pipe have an airlock in it? Is the Y-Strainer or Prefilter clogged?
5.2. Pump does not run
* Circuit breaker or Safety Switch is off or fuse has blown.
* Water level in the tank is too low - Top up or use alternative supply
* Electrical components have been flooded - Contact a licensed electrician to rectify.
* Pump plug is not connected properly, or has been flooded or wet - Isolate power at main switch, remove plug &
allow to dry, only plug it back in if it is safe to do so. If the problem continues, contact a licenced electrician to check
the cause.
* If all of the above are OK, the pump might have overheated and triggered the thermal overload switch. Turn it off
and wait 30 minutes for it to cool down and turn it on again. If the overload switch activates again, have a licenced
Electrician investigate why this has occurred before turning it back on.
5.3. Pump runs but does not deliver water
.
* Check valve is installed backwards. Arrow on valve should point in direction of flow.
* Discharge shut-off valve (if used) may be closed.
* Impeller or volute openings are fully or partially clogged. Disconnect from the power supply, and if you are
competent to do so, disassemble pump and clean. If not, have a pump technician do it for you.
* Pump is air-locked. Re-prime the pump by turning the power off, then removing the screw above the inlet, and
allow the tank water to push the air out. If the tank water does not come out, your tank must be empty. If the
water comes out, re-fit the plug , turn the power back on and test.
* Vertical pumping distance is too high. Reduce distance or upgrade to a larger pump.
5.4. Pump runs and does not stop or runs when no taps in use
* Leak in pipework or leaking toilet cisterns or underground pipe leak (wet soil, muddy, grass growing well!)
* Check this problem thoroughly and carefully, as leaks can be elusive, and cost you loss of power & water = money.

3.6 IMPORTANT NOTE
* If this fails to rectify the problem, call your dealer for service, or call us.
Note that a call out fee and labour costs apply, if it is not found to be warranty.
5.5. Pump not pumping properly
* Too high head or pump under specified - Check specifications.
* Too low water level - Check the water levels
* Loss of prime - Check water level in the tank - re-prime the pump, see 5.1
