===My Brew Unit is Squeaking While Brewing or Rinsing===
If you hear a squeaking sound while brewing or rinsing, your brew unit o-ring likely needs to be lubricated. In some cases, your brew unit o-ring may need to be replaced. You can use Gaggia Food-Safe Lubricant or petroleum gel, such as Vaseline to lubricate the o-ring. Only a little bit of lubricant is needed.

Inside the unit are two tracks which should be lubricated every six months or so for best results in the cup. Watch the video on the right to get the low down on food safe lubricant and how to keep the brew unit functioning smoothly.
