  If the motor of your WOERNER Water Pump doesn't start, it could be due to an interrupted voltage supply or a blocked pump. First, check the power supply, the connection to the voltage supply, and ensure the operating voltage of the motor matches the voltage supply. Also, inspect the fuses and motor protection switches. If the voltage supply is fine, disassemble the pump and motor to check for smooth operation. If there's a blockage, replace the affected component.

Why WOERNER GFZ Water Pump has no build of pressure?
- A
  amandabaileyAug 15, 2025
  A lack of pressure in your WOERNER Water Pump can stem from several causes. It could be due to air in the delivery pipe, a leaking pipe line, or a malfunctioning pressure relief valve. Try deaerating the pipe lines and removing any leakage. Inspect the pressure relief valve for correct opening pressure, dirt, or damage; clean or replace it as needed. Other potential causes include using an inappropriate lubricant, an empty reservoir causing air absorption, or a defective pump unit. Refill lubricant if the reservoir is empty. If the issue persists, the pump unit may need to be sent back to Woerner for testing.

  If the WOERNER Water Pump motor isn't working, several factors could be at play. The lubricant might be unsuitable, the system pressure could be too high, or the ambient temperature might be too low. Try changing the lubricant, checking the pressure control valve, and increasing the ambient temperature. Also, the pump or motor might be fixed. Disassemble the pump and motor to check for smooth operation. If there's a blockade, replace the affected component.
