Why Xylem LOWARA SMB /SVE motor does not start?
The motor of your Xylem Extender might not be starting due to several reasons: a cut-off in the power supply, which would require restoring the power; triggering of the motor's thermal overload protection, in which case you should eliminate the fault and reset the switch; or a faulty motor coil, necessitating a check, repair, or replacement of the motor.
What to do if Xylem LOWARA SMB /SVE Extender motor runs but no water is delivered?
If the motor of your Xylem Extender is running but no water is being delivered, consider these possibilities: there might be no water on the suction side or inside the pump unit, requiring you to fill (prime) the pump unit or suction pipe and open the on-off valves; air could be inside the suction pipe or pump unit, necessitating venting of the pump unit and checking the suction connections; there might be a loss of pressure on the suction side, requiring you to check the NPSH and modify the system if needed; the non-return valve could be blocked, in which case you should clean the valve; or the pipe might be clogged, requiring cleaning.
How to fix Xylem LOWARA SMB /SVE Extender booster set if it is off?
If your Xylem Extender booster set is off, it could be due to a power supply cut-off. In this case, restore the power supply. Another possible reason is that the switch is in the OFF position; if so, turn the switch ON.
Why Xylem LOWARA SMB /SVE booster set does not generate the required pressure?
If your Xylem Extender booster set isn't generating the required pressure, check the following: ensure the on-off valves are open; eliminate any air in the suction pipe and prime the pump units; decrease excessive negative suction head; increase the diameter of the pipes if there's excessive pressure loss on the suction side; replace the foot valve if it's damaged; and reduce water loss if there's excessive pressure loss in the delivery pipes or valve.
Why does my Xylem Extender have frequent start-ups and stops?
Frequent start-ups and stops in your Xylem Extender could stem from a faulty diaphragm pressure tank, requiring repair or replacement. It may also be due to an incorrect pre-charge of the diaphragm pressure tank; in that case, set the new pressure pre-charge value according to the pump unit and setpoint. Also, the pre-charge value of the diaphragm pressure tank might be at zero, meaning the diaphragm pressure tank must be pre-charged.
How to resolve water loss from Xylem LOWARA SMB /SVE pump unit?
If you're experiencing water loss from your Xylem Extender pump unit, it could be due to a worn or damaged mechanical seal, which would require replacement. Another cause could be undue mechanical stress on the pump unit, suggesting the need to support the pipes.
Why Xylem LOWARA SMB /SVE pump unit speed fluctuates without stopping and water consumption?
If the speed of your Xylem Extender pump unit increases and decreases without stopping and without water consumption, it could be due to water loss from the non-return valve, requiring you to check the hydraulic system and the valve. Another possibility is a damaged or undersized diaphragm pressure tank, suggesting the need to repair or replace it.
How to reduce noise from Xylem Extender?
Excessive noise from your Xylem Extender could be due to the return of water when the pump unit is not running, indicating a need to check the non-return valve. It might also be caused by cavitation, suggesting a check of the suction. Another potential cause is hindered rotation of the pump unit, pointing to undue mechanical stress on the pump unit.
What causes tripping of the differential protection in Xylem Extender?
Tripping of the differential protection in your Xylem Extender can be caused by a damaged motor, requiring replacement. It may also be due to a faulty or worn power cable of the motor, in which case you should replace the cable. Another possible cause is a differential switch not compliant with the specifications, suggesting replacement of the differential switch. High differential current may also be the reason; in that case, contact a qualified technician to have the electrical system modified.
Why does Xylem Extender pump unit run at maximum speed without stopping?
If your Xylem Extender pump unit runs at maximum speed without stopping, it could be because the pressure setpoint is not suitable for the system, meaning the value is higher than the pressure that the pump unit can deliver. In that case, set the new setpoint according to the performance of the pump unit. Another reason may be a sensor that is either not connected or damaged, suggesting that you check the hydraulic and electrical connection of the sensor.
