Good device with removable technical problem

After a few times to use, suddenly as with almost all users the unit is no longer.

I then at amazon recession found in the stands,
simply hold the device under hot water and it would run again.
DC tried none - after that I was still on the Philips product page.
There I found a tip farther and put the unit up and running again.

a) If the orange cap off, just snap it back
b) If the device becomes unresponsive, rinse water for two minutes

Have these two tips combined with me and the device has been resumed.

Unclip 1. Orange cap of cutting me a fingernail
2. Cut with a brush and hot water cleaning (as shown at Philips)
3. In addition, I have to drive under the edge of a gnawing arrows on plastic reingeschoben me something
4. Clip on Orange cap
5. Finish runs

Many Greetings,
Markus
