Insert Brew Unit

Hi
There are a couple of things on a delux that can cause this.
Your grind is to fine ( the big knob in the bean hopper is below 8. If it is turn the big knob to a larger number. You can turn the big knob any time to a larger number but it has to be grinding to turn it to a smaller number. 3 cycles before it has changed the grind in the brew unit. You can push the button to stop brewing so you don't have to wait for it to finish. If that is not it go to the next solution.
That is usually a pluged or restricted brew head.
That usually means that you are getting a restriction in the brew head from oils and fine coffee grounds.
Remove the brew unit. Holding the handle, on the top left side is the brew head, there is an outlet pipe that exits the front side towards the door (looks like a long "L" pipe). 2 screws hold it to the top. Remove the 2 screws while holding the manifold ("L" pipe assembly). Once they are removed, lift the l assembly off (be careful, there is an O-ring, spring and at the end a black rubber disk or crystal ball). Do this over a towel to prevent loosing small pieces, mainly the crystal ball.
Now remove the brew screen, by holding the screen with your finger and twisting the thumbscrew (remember, thumbscrew), DON'T use the key to install the screen, use your fingers.
Once the screen is out, look at where the screen was. There are 2 holes. A big one in the center and a small one to the side.
With the brew unit upside down over the towel, insert a paperclip into the small hole and force anything out the other side. I have gotten worms almost a 1" long from this passage. The paper clip has to go from this side to prevent damage to the seat on the other side.
Clean then reassemble. Brew unit on towel right side up. Drop the crystal ball in first. Then the spring small end first on the crystal ball.
Now the O-ring over the spring, then place the manifold on top of that with the pipe towards the machine. Insert your screws (I turn them backwards a little with a little downward pressure until they feel like they drop into the threads. They should turn down easily, if not back them up a little more ( we are trying to find the old threads) and tighten. Install screen, and tighten with your fingers. The screen just needs to be flush with the bottom of the brew head. That should do it

You have a plugged brew head or bent gate valve. I can help with the brew head but not the gate valve.
Remove the brew unit. Holding the handle, the top left side is the brew head. There is an outlet pipe that is either to the front or back. 2 screws hold it to the top. Remove the 2 screws while holding the manifold ( pipe assembly). Once they are removed, lift the assembly off (be careful, there is an O-ring, spring and at the end, and a black rubber disk or ball that you can loose.
Now remove the brew screen, by holding the screen with your finger and twisting the thumbscrew (remember, thumbscrew), DON'T use the key to install the screen, use your fingers.
Once the screen is out look at where the screen was. There are 2 holes. A big one in the center and a small one to the side.

Now the O-ring over the spring, then place the manifold on top of that with the pipe towards the direction it came off. Insert your screws (I turn them backwards a little with a little downward pressure until they feel like they drop into the threads.
