What to do if my DAB Water Pump motor does not start but makes noise?
- A
  Andrew JohnsonAug 14, 2025
  If your DAB Water Pump's motor isn't starting but is making noise, first, make sure the mains voltage matches what's on the data plate. Then, check that the connections are correctly made and correct any errors. Verify that all phases are present on the terminal board; if not, restore the missing phase. Also, check for obstructions in the pump or motor that may be blocking the shaft and remove any obstructions. Finally, consider that the capacitor might be short-circuiting or broken, in which case you should change the capacitor.

Why is the absorbed current too high in my DAB CP Water Pump?
- L
  Linda CalhounAug 18, 2025
  If your DAB Water Pump's absorbed current is too high, start by checking if the fluid density or viscosity is too high and analyse the fluid to be pumped. Also, check for any moving parts scraping against fixed parts and eliminate the cause of the scraping. Ensure the feeding voltage matches the voltage on the data plate and feed the motor with the correct voltage. Lastly, if the pump is running above its plate characteristics, reduce the flow rate.

Why does the motor protection trip too frequently on my DAB CP Water Pump?
- J
  Jerry DunnAug 21, 2025
  If the motor protection of your DAB Water Pump trips too frequently, ensure that the environment temperature is not too high and provide suitable ventilation where the pump is installed. Check the calibration of the protection and calibrate at a current value suitable for the motor absorption at full load. Also, check the motor rotation speed by consulting the motor data plate and inspect the state of the bearings, changing any worn bearings if necessary.

How to fix a DAB CP Water Pump that vibrates and operates noisily?
- T
  Tiffany TaylorAug 25, 2025
  If your DAB Water Pump vibrates and operates noisily, check that the pump and/or the pipes are firmly anchored, and fasten any loose parts. If there is cavitation in the pump, increase the system pressure, keeping within the allowed limits. If the pump is running above its plate characteristics, reduce the flow rate. Ensure that the mains voltage corresponds to the voltage on the data plate.

What to do if the motor protection trips immediately after starting my DAB Water Pump?
- C
  Craig ClarkAug 29, 2025
  If the (external) motor protection of your DAB Water Pump trips immediately after starting, check that all the phases are present on the terminal board (on three-phase models) and restore the missing phase if necessary. Look for possible open or dirty contacts in the protection and change or clean the component concerned. Also, look for possible faulty insulation of the motor, checking the phase resistance and insulation to earth, and change the motor casing with the stator or reset any cables discharging to earth.

How to troubleshoot a DAB Water Pump when the motor doesn't start and makes no noise?
- L
  Lisa HunterSep 1, 2025
  If your DAB Water Pump motor does not start and makes no noise, check the protection fuses and change them if they are burnt-out. Check the electric connections; if the fault is repeated immediately, this means that the motor is short circuiting. Also, check that the motor is live.

What causes insufficient flow in a DAB Water Pump?
- S
  Sarah BrewerSep 5, 2025
  If your DAB Water Pump supplies insufficient flow, the impeller may be worn or blocked. Change the impeller or remove the obstruction. Also, check that the direction of rotation on three-phase versions is correct; if not, invert the connection of two supply wires.

Why does the DAB Water Pump motor turn with difficulty?
- M
  Martin KennedySep 9, 2025
  If the motor of your DAB Water Pump turns with difficulty, check the supply voltage, which may be insufficient. Check whether any moving parts are scraping against fixed parts and eliminate the cause of the scraping. Also, check the state of the bearings and change any worn bearings.
