I have a Philips HX 6240 air floss……I thought the battery was dead, then decided the charger was faulty, stayed on only 1 second then died, batter charge light went out after 30 seconds….not sure how to,separate it, as it has a join 2/3 the way up…..

tried something odd…..I pressed and held the power button whilst pressing the jet button at the same time, it suddenly started working jetting water out…….now works with just the jet button and charge light staying on……maybe it was a stuck button, preventing charging and it working, may have fixed it….
