How to Resolve a Loud Rotary Pump on the ECM Sychronika

Troubleshoot loud rotary pump on ECM Synchronika.

My rotary pump is really loud

If you feel as though the rotary pump in your ECM Synchronika is loud or louder than it should be, read the following to troubleshoot the issue.

Is the machine plumbed in?

  • Yes. Move on to the next question.
  • No. The rotary pump is designed to have water pressure build up against it. If it is drawing water out of a bucket, it may be slightly louder than if it were plumbed in. This is normal.
  • No. You can try raising the water source to be level or higher than the machine. For example, if you have the line going into a bucket, put it on the counter instead of the floor.

Is the pump drawing water?

  • If no water is being drawn the pump will be louder. Try priming the machine if water is not being drawn in.

Inspect the area around the pump

  • Make sure nothing is touching and vibrating off the pump to make it appear as loud.

Inspect the nuts on the underside of the machine to ensure they are tight, but not too tight.

  • If the nuts are loose it will cause the pump motor to be loud from movement.
  • If you tighten the nuts and tighten them too much it will cause the pump to be loud due to not being able to adequately absorb the vibration, or the mount will rip.
  • From the factory the Synchronika has two nuts on the underside to prevent the pump from moving during shipping. If you have not removed these, then the pump will run louder because the mounts can not absorb the vibration.
  • If there are no visible signs of anything being loose, the pump is drawing water, and the machine is functioning fine but the pump is too loud, the bearings within the pump may be failing due to wear and tear, etc. Replace.
