Troubleshoot loud pump on Profitec Pro 500 PID.

My Pump is Really Loud

If the pump in your Profitec Pro 500 PID is very noisy while brewing or refilling the boiler, this is not normal but easy to resolve. The instructions below cover how to determine the cause of a noisy pump in your machine.

  • It is possible that if the vibration pump within the machine is loud this is due to either the pump slipping out of one of the mounts, or the screw has come out of the mount and the motor is moving around. One of the rubber mounts may be ripped, or if the machine is older the mounts could be dried out and hard, causing them to make the machine louder due to not being able to absorb the vibration well. These can all be visually inspected.
  • The pump also may be on its way to failure. This is not always the case but it can be one of the symptoms of a failing pump. Run the vibration pump pressure testing to determine if the pump is displaying any other signs of failure. Please refer to this article for instructions.
