  1. My battery and charging problems were solved by spraying the plug and pins with contact spray. Corrosion completely prevents the waterpik from charging I highly recommend to try this first!

  2. Help my water pick is about 2 years old and the part that my batteries go in the little coils broke off (2) of them can I replace e the bottom where the batteries go or should I buy another one? I am on a limited income! Thank you Janice Wertz

        1. Hi Rick, Your WP-871 toothbrush and the similar WP-860, WP-861, WP-862, WP-872, WP-881, WP-882 toothbrushes from Waterpik will open up in the same way. The older toothbrushes from Waterpik had a groove across the bottom of the handle which you could use a coin or large screwdriver to undo an eighth of a turn. Does your brush have this groove?
