SOURCE: Everything sounds like its working...but nothing.

Another thing might be your coffee is too finely ground or tamped too tightly.  If water comes through the filter basket, try using a little less coffee and tamping less firmly.  If that works, you're all set.  If you still have a problem, you may need to switch to slightly coarser grind.

the needle in your k-cup holder is broken and over presure built up in the k-cup, and create security stop. Change our k-kup holder. if the needle is still in place the k-cup must be puncture on both side on top and bottom. if is right our needle can be block. clean with a little rod of stainless steel.

SOURCE: The pump appears to be failing and will not build

Dont think its the pump. More likely to be a seal

SOURCE: Insufficient pressure to force water through coffee

Propably the vibrating water pump is the problem.
It might be full of scale and it can not create any pressure or it is completetly damage and need to be replaced.
First we sugest to perform a descaling of the machine and try again.
Second you should try to reduce by little the quantity of the grounded coffee used. Aprox you should use 7 to7.5 gr of coffee. If you try to use about 6 to 6.5 and you have the coffee runing out from the machine like in 25 sec you have about 30 cc of water. Then try to clean the group shower which it can be ansrew by one cetrer screw and if you can you can open the machine and remove to clean also the coffee group solenoid valve. Bothe the valve and shower can be full of dry coffee that can blocked the way of water coming to the grounded coffee.
If you manage to clean everything above and the machine work ok so from now on in order to avoid the problem again try to flush water from the group many times without any coffee. With this is like you wash the group shower and valve from any remai coffee.
Good luck

SOURCE: I can't get the water to come through the coffee holder.

Remove the brew head. Pry out the metal coffee filter, then pry out the rubber gasket. There is a small black plastic insert that is likely gunked up with coffee buildup. Clean the parts well, reassemble, and then try again.
If you are a good "tamper", you can leave out the rubber gasket and plastic insert entirely, and just go with the the filter. It takes a bit of practice, but you will get equally good crema if you match the grind to your tamp pressure.

The coffee coming from the machine is awful. It was a precipitous change. It is weak and tasteless. Same brand of whole bean I have always used.

Good morning Kenneth.

There are a couple directions you could take to diagnose this.
Since the change happened overnight, or quickly in any case, this tends to suggest clogging or contamination that happened recently.
My suggestions:
  1. Try running a batch of coffee with no grounds in at all. Fill up the water, run it on 'pre-ground' mode, and let the hot water run into the tank. Is the water clear in appearance as expected? Does the water run into the pot in about the time you'd expect? Does it flow readily from the filter outlet into the pot, or come in dribbles and spurts? And... if you taste the warm water, does it taste like nice neutral water, or is there an overall taste?
  2. If any of the above is true, then your water path can me mucked up. A few possibilities here would be :
    1. There is usually a water filter in the unit, which will get gunked up with water filtrate, or just algae over time. You'll need to look at your manual for your particular model to find how to access it. Changing the filter can make a big difference in both taste and in how reliably water flows from the reservoir.
    2. The filter cone is gunked up. Usually you can remove the entire filter cone assembly for cleaning. There is pretty much always a spring-loaded push valve on the bottom that will not allow coffee to flow out the bottom unless the pot is in place. This can get majorly gunked up with old coffee grounds that overflowed at some point or another. Make sure the valve is free of debris, along with the surrounding area.
  3. if the water path is ok, then 'weak' coffee translates into 'the water and the grounds are not interacting enough'. that can come from a couple directions:
    1. Not enough coffee, or stale coffee. I'm discounting that since you said you'd already tried both pre-ground and auto, and i assume you used the same amount of coffee grounds.
    2. Water is not hot enough to extract coffee essence from the grounds. If the system is pumping the water over the grounds, but it's cold, then if you are on morning auto-mode, it's possible the morning timer is running tepid water, and then heating it with the pot heater.
    3. Water is hot, but not in contact with the grounds long enough to extract much. This could either be that the system is flowing really fast - whether high water flow would mean fast pass-through will depend on the filter specifics, or that it's by=passing the filter. If there is an overflow catch that will still direct the coffee to the pot is it misses, then you may be either flooding and catching, or the filter might be mis-seated, so that some significant amount of the water can just flow past it. Your description reminds me of some times that the paper filter in my system has folded over, so that the water is dripping against the outside of the paper filter and then running down to the bottom of the filter holder. Bleccch.
    Hoping this is helpful!

    Good Luck

Water pressure is too low. How to adjust?

If water/pump pressure is below 9 bar, then you will have to adjust the pump. Remove the right side panel, pump is usually located there, find the big brass head with 2 water lines coming to it, on the side of it is an adjustment nut and or screw depending on pump model. Adjust tighter gives more pressure.

The coffee comes through the machine too fast.

It can be 2 problems: 1Too big granulation of grinded coffee(in this case we have cup filled fast and we have yellow and thin cream or traces of it) Adjust the grinding 2 Filter holders filter(where you put grinded coffee is broken) sometimes it brakes at curves and it is hard to see, wash it and inspect it carefully. if it is broken replace

Top will not unlock

It seems to be caused by pressure build up (not a vacuum) when the outlet of the pod holder gets blocked. There are three plastic bolts that slide into place to lock the lid as the lever is operated. Pressure forces the lid up and increases the friction on the bolts to the point where they won't operate. Solutions 1 and 2: First disconnect Senseo from the electric supply. Solution 1 is to press down on the lid to overcome the pressure and then operate the lever to unlock. Didn't work for me. Solution 2 is to get a table knife, not sharp, no serrations but with a rounded end, not pointed. Insert under lid just to right of pod holder handle, at an upwards angle of about 20 degrees to the horizontal. Then aim for the opposite 11 o'clock position on the closed lid. With a few tries the knife blade should slide between the top of the pod holder and the rubber sealing gasket releasing the pressure. Beware hot steam/water as pressure is released - wear gloves. Open lid, unblock pod holder hole with a pin, fill and heat resevoir and then flush through without a coffee pod in place.

Coffee grounds in the cup

since you said usually... I suspect the rubber seal that surrounds the top needle is not seating well...
you can verify this by making a beverage with a k-cup and, just before the water starts, add a little hand pressure to the K-cup arm pushing down a little bit... not hard...
If it consistently makes a good beverage, then we focus our attention to that piece of the brewer...
when the consistency of the water changes, it tells me to look for leaks or unusual percolation of water...

you can verify the K-cup holder is ok... but another way to simulate the hand pressure is to put a shim of some sorts under the lip of the k-cup... like the thickness of a couple sheets of paper under the rim... not the actual k-cup... but the k-cup holder... raising it up a smidge is the same as the slight hand pressure...

I would look to see if the rubber seal has come loose around the top needle....

The locks shut due to a pressure build up in the pod chamber usually caused by a blocked filter in the centre of the pod holder.

The only way to open the unit is to releive the pressure. The pressure will normally reduce over time, the duration being determined by the pressure build up, condition of pod seals and the strength of the blockage.

A quick DIY solution: (small cable tie and screwdriver required)
Un plug the unit from the mains:
Remove the water container and prise open the rear snap fit panel of the unit carefully using a screwdriver to expose the internal workings, the overflow pipe at the top of the cover must be disconnected to gain enough access to work on the unit.
.The small metal boiler in the centre of the unit is used to heat the water for the machine, if the boiler is still hot allow it to cool down sufficiently for work to commence.
The exit pipe at the top of the boiler feeds directly to the pod chamber, if you squeeze this pipe you will feel that it is under pressure. Cut the cable tie connecting the pipe to the boiler (be careful, dont cut the pipe) and remove the pipe to release the pressure, a small ammount of water will be released during the procedure. The lid should open.
Reconnect the pipe to the boiler replace the cable tie, refit the rear cover making sure to push the overflow pipe back on before you snap the cover shut.
Remove the pod holder and clear the blockage blow through the holder in the reverse direction to ensure the filter is clear.
Replace the pod holder and pour a small amount of water on to it. The water should exit through the delivery spouts if the path is clear.
JOB Done.
