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.
To correct this issue, you can use Gaggia Food-Safe Lubricant or a petroleum jelly such as Vaseline to lubricate the o-ring. Only a little bit of lubricant is needed.
