A:Answer You do not need a plumber to clean the lower filter, just follow the cleaning instructions given in the manual. It is a very simple and straight forward procedure. Worse case, if you do not feel comfortable doing it yourself, any handyman should be able to help you out. I have found that plumbers are a bit more expensive than the average handyman. If you decided to not clean it, you may find the machine to start smelling foul. Good Luck!
