I figured out the problem for my Clean & Renew unit. Mine is 2 years old. About 3 months ago, I cleaned the buildup of whisker material from the TOP of the drain port [Left Side as you look at the unit] If you take out the cleaning solution cartridge and turn the unit upside down, you see the pump and the return ports. The return port is the smaller of the two. I found that there was a mass of dried whiskers in a few clumps clogging the return port. These clumps must have come loose and got caught within the drain port. I had noticed when I had the leaking problem I could hear bubbling just after the pump ran and the shaver turned off. I removed the clumps of whiskers and no more bubbling sounds and NO MORE LEAKS. My guess is that the fluid was draining back into the intake area and leaking on top of the cartridge. Hope this helps

My braun Contour 5790 does not charge in either the cleaning stand or by the cord alone. Can you help me in this dilema?

It my be the batteries but they usually go bad very gradually and you should still be able to use it from the cord. It sounds more like a problem with the circuit board.

I suggest that you first find out if it can be covered under warranty. You can call an authorized service center at 847-869-7755. They can tell by the date code on it when it was made. If it was made less than 2 years ago. you shouldn't need your receipt.

My former razor, Braun 5414 would take 110-240AC as well as 12 DC. Now have Contour 5790, and want to know if itcan also use12 volt DC.

According to the Braun manual for your 5414 Contour, the specs for charging are printed on the electric shaver cord plug. (it's REALLY small print, so I'd get a magnifying lens to look at it!)

There isn't anything in the manual about the multiple voltage for charging the shaver, so I'd have to defer to the Braun (Gillette/Proctor & Gamble) customer service folks to make absolutely certain of what can and can't be used as a charging voltage before trying.

Here's a link to your manual, in case you're missing yours.

You can ALSO reach the Braun Customer Service folks by calling them at 1-800-BRAUN 11 (1-800-272-8611)

I hope you find this Very Helpful and best regards!

Non cleaning razor

Dear Freddofrog,
please ensure you have removed the plastic plugs from the cleaning fluid container. If you have removed these i would suggest that the fluid contaner is faulty, your place of purchase should exchange this for you with no problem.

Device will not charge...

Just take it back to the store where it was purchased and they will trade it for a "New" (Not broken) one. It's the holiday season and you have a week or two, on returns. There is a two year warranty on the product ( Braun 5790 ), if you want to go that route. You can contact the company @ 1-800-BRAUN-11, the person, "I" spoke with, was very nice and didn't act like I was a problem and she didn't try to just blow me off.
Good Luck-

Base floods with solution during cleaning cycle

OK, Remove shaver from cleaning base. Raise top cover as if you are going to replace the cleaning cartridge. Now, look into the cleaning cup where you put the shaver into.You will notice a small hole on the bottom left side. With a Q-tip ,clean out the beard hair from the hole.If you have a model 5301 which is located on the bottom of the base, you should be able to push the Q-tip all the way through the hole. This will allow the liquid to flow back down into the cartridge.This is whats causing the overflow.
