I have the same problem, but worked out a solution. These days things are made to be thrown soon after their warranty, so we can keep the companies in business. As an engineer I tried to put replacement rechargeable batteries. But that did not quite work as the built in charger connection goes faulty with calcium deposits and wear. Also the electric motor needs more than the meagre 2 volts from two AA batteries to provide any pressure. So I modified the connector and made provision to connect ..

I have had this waterpick for a few years now and I had to change three units under guarantee. The battery fails and it is the end of it. Waterpik should use rechargeable batterees to resolve the problem. Pity. It is so handy.

I don't think it is a battery failure but the fine jet getting clogged. I had this with a Panasonic EW DJ40

i bought one 2 years ago but after 2 months the battery failed. The charging piont fills with water and the connections corrode. The water bottle also cracked due to the vaccum crfeated during operation.After reading the other comments I think Waterpik should show some sympathy with customers and recall this model.

good when working. ONce a button broke nothing could be fixed. It needs to be more resistant for the price we pay! It lasted me a few months.

I bought one of these a month ago as I have braces, top and bottom. Seen dentist and hygenist since and they are amazed at how clean my mouth is. Recommend use with warm water. I think it's excellent.
