Can't get it off of last brew. What do I do to get it to brew?

The comments on Amazon for this coffee machine suggest you should throw it away and buy a different brand name in the future.
That message has been reported on the internet to mean that it is broken for good, unfortunately, and you lost your money on it.

Quoting from typical Amazon reviews above:

"1.0 out of 5 stars"Last Brew"
ByAnita W.on March 17, 2018
Color: Chrome'Verified Purchase
item lasted exactly 1 year. it is stuck on mode "last brew". it seems to be a typical problem with no fix. how ironic everybody has this same issue "last brew". not funny to wake up to that message and no coffee to boot. it did look beautiful on my counter with matching toaster."

Amazon com Customer reviews BELLA LINEA Collection 12 Cup Programmable...

I have a Bella Linea programmable with the same problem.

I sent an email to [email protected] but have not heard anything back yet. It's actually a very nice coffee maker and worked fine for the first week, but yesterday I tried to brew a pot and it just defaulted to "Last Brew" mode.

I tried standard and auto brew modes but they get the same result.

Time to buy new one the elements out...

Try pushing a paper clip or dental pic up the spout, the part that pokes into the K-cup, they often plug up.

If you don't brew often enough you will loose a small amount of water in the tank due to evaporation while the tank heater comes on and goes off to maintain the proper brewing temperature, so if it has been a while since you last brewed, without coffee in brew basket put a carafe of water thru the brewer, you will get less than a full carafe out because it fills the evaporated space in the tank first then uses the rest to brew. Once your tank heater shuts off usually 5 minutes on less you will get out all the volume you put in.

First clean and please try again
Fill the reservoir with water.
Place your mug underneath the machine.
Add the K-Cup.
Choose your serving size.
Press the brew button to begin brewing.
Enjoy your delicious cup of coffee! .

f 17 is no water flow. It usually occurs when the brew unit has not been cleaned regularly, when the coffee grind size is set too fine, or when oily beans are used. You can try to soak the brew unit in hot water for a while, and run water through it in the sink. Unfortunately, most cases require brew unit replacement. A properly cleaned and maintained brew unit should last the life of the machine.

Sounds to me like you need to set the unit to the correct/actual time.

Descale your brewer

First, you're going to need to get the brew group out. Check this out to get the brew group out. You need to remove a screw and pull unless you're really crafty.

This video will help.
After that:

a) Yes, lubing will help.
b) Replace the o-ring on the piston in the brew group (it should be orange). It gets old and gummy creating resistance.
c) Reinforce the weak plastic that gets over-torqued.

I own three of these units, one from 2007 (made in Italy, never broke, has tens of thousands of brews) and two newer units (made in Eastern Europe, fewer brews, both broke). I can distinguish the newer ones because they have a "sleep mode". They really overtorque the gear.

I tried repairing with just glue and that lasted (surprisingly) several months. I tried again by using a thick paperclip as a drill bit and that lasted 7 months.

Now with the holes piloted, I drilled a little wider and put in heavier metal from a heavy-duty binder clip. Cheap and very strong! Let's see how long this lasts.

See before and after pictures. This metal won't bend!
