If it stops working, then you need to change the head/cutters! Read the manufacturer’s instruction. This shaver is built in such away to stop working after 18 months unless you change the cutter

After two years, just stopped working, even though fully charged

I have similar experience with the shaver stopped working, had it for about 1 year. I have been very happy with the shaver. Fully charged, and usually long time before it needs recharging, but suddenly its just dead. No lights showing.

My wife bought this shaver for me about 9 months ago. Until a fortnight ago the shaver worked really well. I use it as a wet shaver and that gives me a really close shave. unfortunately the shaver stopped working from one day to the other.It's fully charged and there are no lights showing. But no matter what I do I can't get it to run again. So I'm back to using my old trusted Phillipshave.

Had S5 about 18 months and has suddenly will not work. It is fully charged , but when I switch on for shaving a small red lock signal appears and I cannot find a way to restart the razor which up till now has been good.

I own the old Braun Series 5 5140 and so I was excited to see how this new model compares. I was particularly interested to see how it performed as a wet shaver. Firstly, out of the box it is incredibly easy to set up and start using. The controls are very easy and it feels nice to hold -it feels like a premium product. There is the option of either having the shaver head fixed or moving. Personally, I believe you get a better cut if you leave it on fixed all the time. When you are dry shaving it performs very well. Not quite as smooth as a blade razor cut, but still very good and certainly good enough for day to day use. My only criticism is when you try to use it as a wet shaver with gel and this is because it leaves a lot of hair shavings on your face and this takes a bit longer to clean up at the end - without any noticeable improvement in comfort or closeness of shave. It is easy to clean as you can pop the shaver head off and run it under the tap. Overall I am happy with the product and use it most days.

My last electric shaver was a Braun Wet & Dry shaver from 4 years ago but this version of their Wet & Dry is definitely a cut above that. One of the disappointing parts of my previous shaver was the trimmer attachment but this has improved to be something that is useable. The feature that allows the head to move in a rocking motion as it moves over the face and chin is brilliant and I think makes for a closer shave as the shavehead stays at the right angle to the skin. You can also lock the position of the shavehead which comes in handy when edging up to your sideburns or beard edge. The fact that it is water resistant to 5 metres means I don't feel conscious about ruining it when cleaning the shaver or using it in the shower. Overall this is a great piece of kit and well worth a purchase if you want an alternative to a wet shave as it gives a really close shave which in my opinion is the best I have ever had from any of my previous electric shavers over the last 25 years. Cleaning the shave head is easy as a simple click of the side buttons and it pops off. The battery is powerful too and lasts for ages with a quick charge too. The only thing I miss is a simple padded travel pouch in the box but that wouldn't put me off buying it. If you are in the market for a new shaver then don't hesitate to buy Braun Series 5 5140s.

Having used electric shavers for several years now, I thought I knew what to expect, but was blown away with the new Braun 5140s. The smooth shave achieved from an electric shaver was like nothing before and felt as close as a wet shave, just without the hasssle. It is so versatile in the ways it can be used, like even in the shower, which saves time in the morning before work. Someone commented at work if I had a Turkish shave, but it was just my new Braun shaver. It is so easy to charge, use and clean and the battery lasts way longer than any of my previous shavers. Overall an outstanding product, highly recommended.

Over the years I have tried a fair number of electric shavers and have always found myself reverting to a wet shave following disappointment in the results. On reading about the features offered by the Braun 5140; wet or dry, the option to use shaving foam or in the shower I was hopeful that this could finally be the product to keep me from the manual razor. As is typical of a Braun product the shaver is well packaged, although the contents (shaver, charging plug, protective cap, cleaning brush, user manual) were well short of filling the box to capacity. While I feel capable of wielding a shaver straight from the box, I was drawn to the 140 page manual. Something of this size must have some relevant details which may be important and I was keen to find out more about using with shaving foam or in the shower. On closer examination of the manual I soon found that my hope of it containing any useful information had been misplaced. The English language section was just 5 pages long with a further 2 pages at the front illustrating the 5 series range (at least I had plenty of time to determine which of the illustrations were for features on another model as I was not going to have to read all 140 pages). Nowhere in the manual was there any mention of using shaving foam or using in the shower, the shaving tips section even stated “always shave before washing your face”. I was beginning to think this was not the product I had previously read about. The shaver itself feels really comfortable and sturdy in the hand and seems well made. The unit is quick to charge and appears to retain power well. It will obviously depend on how long you use the device, however, I found I was getting at least 2 weeks before I even needed to think about recharging. On first use I kept things simple; basic dry shave with 1 day stubble. Initial impressions were very good, the flexible head was excellent and no matter what the angle it was held the foil seemed to be in constant contact with my face. The results seemed to be impressive with the added bonus of not experiencing the painful shaving rash which I normally suffer. Unfortunately before long I realised that the finish was not as smooth or constant as I had thought and I had missed several spot particularly under the jaw line. Next day, after paying extra attention to the awkward spots I was rewarded with a smooth consistent shave. Next challenge, how would it cope with a few days growth? Once again, providing sufficient time and attention is given the results are excellent, with the shaver powering through with ease. The shaver is easy to clean, simply tap to clear the cassette or run under the tap (it would have been nice if the recommended light machine oil had been included). With shaving foam – I have to confess to being dubious about this, however I sparingly applied some shaving gel and was surprised at how the shaver appeared to not be negatively affected. After a while I noticed that the foam appeared to be clogging the foil and the shaver was not cutting very well. A quick rinse under the tap the foil was clear and the shaver was working again, unfortunately despite attempting to shake the water out of the shaver it was dripping everywhere as I continued to shave. In all I had to rinse the foil three times during the shave and by the end had water, foam etc dripping everywhere. While the shaver may work with foam or when wet, I couldn’t recommend it; it’s much harder to check that you haven’t missed bits then you have to clear up the mess which has been dripping from the shaver. In conclusion, as a basic dry shaver I would highly recommend the Braun 5 series. While it can’t match the closeness of a wet razor, with a little perseverance it produces an excellent close shave even in the awkward spots. Add to that the fact that I’m still to experience any form of shaving rash and I certainly won’t be reverting back to a razor any time soon. As for the wet use or with foam, well while I may not have been impressed the shaver shines without the need of these gimmicks.

I have been an electric razor user for over a year now after 20+ years of wet shaving. After much research I originally opted for a braun 7 series, simply due to the fact that it came with a cleaning unit in the charger. I was recently introduced to the braun 5140 and though in name it appears to be a lesser model than the 7 series, it most definitely isn't. Firstly it looks good and feels solid in the hand. I first used it for 2 days growth and it handled it no problem (I have a decent growth after 24hrs), I then used it daily for a couple of weeks and only had to charge it once more. I also used it on 4 days growth recently and though it took a bit longer the end result was just as good. The trimmer tool is very useful and the facility to fix the head into a single position helps for the final sweep to make sure you haven't missed anywhere. I would definitely recommend this shaver if you don't need fancy add ons like charger stands and cleaners. I keep this one at work now and use it regularly.
