Shark Vacuums - Page 9 - Recent Questions, Troubleshooting & Support

Shark products don't have serial numbers. They are meant to be disposable therefore have no need for serial numbers. Shark doesn't even have a parts dept.

Over 80% of steamers stop working within the first year. Mineral deposits, poor build quality, etc.

Bad PCB. Most rechargeable Sharks and Dysons fail in 2 years. Take it to your local vac shop for assessment if you want to be sure.

Brand Developers has recently discovered an issue where the cord may cause a burn or electric shock. Only the Shark Navigator Lift-Away (NV350) units manufactured prior to 18th October, 2014 (which bear a batch code 4811A to 4114A inclusive) are affected. Hope this helps.

replace battery/charger

It seems strange that it failed so quickly. Don't use tap water, it will wreck the element and potentially block up the galleries. I have a budget tip you can try. Mix up a solution of citric acid powder (safe to use - it's a baking ingredient) in DISTILLED WATER. A tablespoon per 2 cups should be strong enough. Make sure the powder is sufficiently dissolved and add it to the steamer tank. Turn it on and wait for a while (maybe 10 - 15 mins?) and pump the mop on the floor - with a bit of luck, it will purge out the steamer and start working. Drain it out and thoroughly rinse the tank. Refill with distilled water and use it until the lines and galleries are free of the powdered acid solution. Store the steamer EMPTY of all water and in future only use distilled water (citric acid powder does an amazing job of cleaning electric kettles too)

vacuum hose blocked preventing air flow

Haven't had this problem, but sounds like an obstruction of some kind. Turn the vacuum upside down and clean any lint, thread or hair around the roller and make sure there is nothing stuck in there that would impede the roller. I have a long haired dog and have to do this regularly.
