Why is my DAB VA 55/130 so noisy?
If your DAB Water Pump is noisy, there might be air trapped inside. Try bleeding the pump to remove any air. Also, check if the intake pressure is too low and increase it if necessary.
How to reduce noise in my DAB VA 55/130 system?
If your DAB Water Pump system is producing excessive noise, it could be due to a flow rate that is too high. Try selecting a lower speed. Another possible cause is air in the system, so try bleeding the system to remove any trapped air.
What to do if my DAB Water Pump starts and then stops after a short time?
If your DAB Water Pump starts and then stops shortly after, it might be due to dirt or scale interfering with the rotor and stator lining, or between the impeller and pump body. Ensure the shaft turns freely and remove any dirt or scale.
How to troubleshoot a DAB Water Pump that does not start?
If your DAB Water Pump doesn't start, begin by checking the electrical connections and fuses to ensure there's a supply voltage. Verify that the supply voltage matches the data on the pump's plate. For single-phase motors, a faulty capacitor could be the issue, so consider changing it. Lastly, the rotor might be blocked by deposits; select the maximum speed or manually free it with a screwdriver.
