  • Scale Buildup: Scale can restrict water flow and reduce pressure. Descaling your machine regularly is essential to prevent this. Use a descaling solution recommended by the manufacturer. Follow the instructions carefully to avoid damaging your machine.
  • Pump Wear: Over time, the pump's internal components can wear down, reducing its efficiency. If descaling doesn't resolve the issue, you might need to adjust or replace the pump. Consider this if your machine is several years old and has seen heavy use. Regular maintenance can prolong the life of the pump and ensure optimal pressure.

• Noisy Pump: A noisy pump can be annoying and is often a sign of a problem:

  • Air in the System: Air bubbles in the pump can cause it to vibrate and make noise. Try purging the system by running the pump with the steam wand open until the water flows smoothly.
  • Loose Components: Check for any loose connections or components in the pump housing. Tightening them might reduce the noise. Inspect the pump for any signs of wear or damage.
  • Pump Failure: Excessive noise can also be a sign of pump failure. If the noise is persistent and accompanied by other symptoms, you might need to replace the pump. Pay attention to changes in the sound of your pump. Does it sound louder than usual, or is there a new grinding noise? Addressing noise issues early can prevent more significant problems down the line.

By following these troubleshooting tips, you can often identify and resolve common rotary pump problems. Remember to always unplug your machine before attempting any repairs and consult the machine's manual for specific instructions.
