Why is my Dutypoint Water Pump vibrating or noisy?
H
haydenmarkAug 16, 2025
A vibrating or noisy Dutypoint Water Pump can be attributed to a few potential causes. One reason could be pump cavitation. Try increasing the discharge back pressure slightly by progressively closing a manual isolating valve on the discharge side until the cavitation stops. Alternatively, the rotating parts of the pump might be obstructed, for example, the impeller obstructed by foreign matter. In this case, strip the pump to inspect and rectify. Lastly, worn motor bearings can also cause these symptoms; check and rectify as needed.

What to do if my Dutypoint Water Pump won't start?

Mrs. Stephanie HarrisAug 21, 2025
If your Dutypoint Water Pump isn't starting, there are a few things you can check. First, ensure that there is electrical power reaching the pump; if not, check and rectify. Next, inspect the fuse, as a blown fuse could be the culprit; check and replace if necessary. Lastly, examine the overload trip/MCB and reset it if it has tripped.

What causes an overload trip on my Dutypoint Water Pump?
P
Patrick WrightAug 25, 2025
An overload trip on your Dutypoint Water Pump can stem from several issues. It could be due to a partial blockage in the pipework or pump chamber; check and rectify any obstructions. A momentary loss of one phase of the power supply can also trigger it; check the power supply and try again. Additionally, a discharge flow rate that's too high can cause an overload; reduce the flow rate by increasing the discharge back pressure slightly by progressively closing a manual isolating valve on the discharge side, then try again. Finally, the overload trip setting might be too low for the rated duty; check and, if necessary, reset the overload trip value.

What to do if my Dutypoint Water Pump has low or zero output discharge rate?

Linda BennettAug 28, 2025
If your Dutypoint Water Pump has a low or zero output discharge rate, consider these possible causes. The rotating parts of the pump could be obstructed; strip the pump to inspect and rectify. The pump may not be primed; prime and air-bleed the pump, after checking the mechanical seal for damage. A valve in the suction pipework might be closed or partially closed; check that all appropriate valves are fully open. Finally, the pump rotation could be incorrect; check and rectify.

Why is my Dutypoint ScubaTANK WX Water Pump break tank overflowing?
M
Maria HughesAug 31, 2025
If your Dutypoint ScubaTANK WX Water Pump's break tank is overflowing, one potential cause is a solenoid valve jammed open due to debris. To resolve this, clean the solenoid valve diaphragm:
1. Press the red STOP button(s) on the inverter control panel(s).
2. Close the incoming isolation valve.
3. Isolate the electrical supply.
4. Loosen the 4 screws as shown in Cleaning Solenoid Valve Diaphragm.
5. Remove the diaphragm and spring shown in Cleaning Solenoid Valve Diaphragm.
6. Remove all dirt from the diaphragm and housing.
7. Replace all parts.
Another possible cause is that the probe relay settings have been adjusted. Check the probe relay settings according to Correct Probe Relay Settings in the control panel. Finally, a loss of power to the probe relays can cause overflowing.

What does ACTIVE DIG. IN. 3 mean on my Dutypoint Water Pump?

daniel95Sep 4, 2025
If your Dutypoint Water Pump displays 'ACTIVE DIG. IN. 3', it means that Digital input 3 contact is opened, indicating a 'Low Water Level' condition. First, check that the incoming mains pressure is as expected. Second, check the water level in the tank. The error should reset automatically when Digital Input 3 contact is closed.

What does ACTIVE DIG. IN. 1 mean on my Dutypoint Water Pump?
J
Jane HarrisonSep 8, 2025
If your Dutypoint Water Pump displays 'ACTIVE DIG. IN. 1', it indicates that Digital input 1 contact is opened, which the system interprets as ‘External On/Off’. To resolve this, first verify that any external signal (e.g., BMS) is set to deactivate the pump set. The error should reset automatically when Digital Input 1 contact is closed.

What to do if my Dutypoint Water Pump has no water and shows a DRY RUN COSPHI error?
M
Molly JenningsNov 12, 2025
If your Dutypoint Water Pump displays a 'NO WATER- (DRY RUN COSPHI)' error, it could be due to several reasons. First, the minimum pressure requirement might not be reached within the set period. To solve this:
1. Turn off the main electrical isolator.
2. Close the discharge isolation valve.
3. Vent the pumps.
4. Turn on the main electrical isolator.
5. Check the unit runs up to the set pressure and pump motors shut down.
6. Open the discharge valve slowly, ensuring the set pressure is maintained.
Another cause might be an air lock in the pump. To resolve this:
1. Press the red STOP button on the inverter drive(s) to stop the unit.
2. Disconnect the pump(s) by loosening the union directly underneath the lid, above the pump discharge pipeline.
3. Lean/tilt the pump(s) over as fa...
