My new Bosch Maxx 6 Sensitive Dryer stops drying after a couple of minutes and the reservoir light flashes, but it's not even using the reservoir....help!

It could be that it is over heating. I would check the vent tube to see if it's clogged or check the part where you hook up the vent to the dryer

Well I would recheck the water reservoir is fully inserted ....the door has no debris inside the lock....the bottom filter is cleaned not just the door filter.if this still not fixes then try a reset by switching off at socket then whilst holding start button without releasing for at least five seconds turn on power and listen for a click.sometimes a sensor is stuck and not relaying proper status.

Because this isn't a US Product. Try using a Service Contractor locally.

probaly your pump is faulty

There is a thermal overload switch behind the back cover. It has overloaded because the big lumps of lint in a) lint basket, b) small vents either side of the vent basket (use a chopstick), c) in the big pull out condenser unit at the front bottom left, and d) reach right to the slot for the condenser unit and scrape all the lint out of the back.

Now you can do the reset - unplug your dryer first. You will need a Torx T15 screwdriver to undo the all screws around the fan & drum cover, then use a thin blade to pop off the back cover. If you don't have a Torx screwdriver, you will have to buy or borrow one - there are just too many screws to use anything else.

I was thinking of drilling a 6mm hole in about the right spot so I can poke a chopstick through to press the reset button.

That is a bad motor. It is overheating and the overload is shutting it down. Check to see if there is lint buildup on the motor. If not, you will need a new motor.

Technician just solved that annoying problem. My dryer is few months old and without pump, so condensed water is dripping to tank by gravity. During drying cloth is collected on filter and condenser, but some amount of cloth goes into pipes and canals on the bottom of dryer and clogged non-return valve where tank is inserted. Side panel ha has to be removed, canals and valve cleaned. To prevent problem technician suggested condenser and filter cleaning after every use. Valve can be removed from bottom without removing side panel.

Most likely the heating element or a thermostat.

Yes,it is the first thing to check ,If you can somehow see if its glowing when you start the dryer.It may also be a thermal fuse.

Hi Guys...
At least I can shed some light on how to open the bottom part.
When you are looking into the dryer with the door open, take a look at the bottom hinge of the door. There is what looks like to be button popped out slightly.. 
Place your thumb on it and press. This should open the bottom part of the dryer.  Then clear out the gap between where the lint filter connects to the other units below it (when the door is closed...)
Hope this makes sense... there seems to be a sensor there..  I just cleaned mine so praying that the beeps stop.. Its been driving us mad for the last 8 months!
