I have a Jura Impressa F9 that is producing weak coffee. It has plenty of pressure. There seems to not be enough coffee being dispensed by the grinder. Unlike another machine I have the pucks are smaller and crumble. I took it apart and cleaned everything and replaced all the O rings. Any suggestions?

Sounds like you have something clogged. First see if your unit is under warranty. If it is, then working on it will void your warranty and instead you should take to a certified warranty center.
If it is out of warranty I suggest be sure that is un-plugged then try and clean as much of it as you can without immersing the electrical parts of it.
If that doesn't work then it probably needs replacement parts. In 98% of small appliance cases it's usually more economical to simply buy a new one.

SOURCE: weak coffee

It sounds like you may have lost the sprayhead. It is under the brew basket (above the place where you put the basket with the filter and the coffee). Sometimes they get loose and you don't realize it and it can fall in the grounds and get tossed out after brewing.

SOURCE: WEAK COFFEE & NOT HOT ENOUGH

Basing on personal experience (you can find more on Google probably), solutions are:

On percolated (filter) coffee machines:

Check water temp, if water temp is insufficient , most common is scale heating element , faulty element, faulty thermostat.
Check if water is dripping right at the center of the filter, if it is dripping on one side because the orifice is clogged, that can result in weak coffee.
Coffee blend not well distributed on filter basket.

On Espresso machines:

Check water temp, same as filter coffee machines (thermostat element, scale on heating chamber).
Ensure that coffee is filled correctly in the filter cup (fill at level), and well pressed.
Ensure that the coffee mixture that you are using is not too coarse, buy the apposite one for espresso.
Ensure that you are not leaving the machine brewing for a time that is too long, and Italian coffee cup is very small, approximately one regular shot.

On the hob moka pots (espresso, Moka and Bialetti type):

This are the trickiest ones, you need art and practice to get a good espresso with a Moka, but when you learn, the result is better than what you may get with an home electrical espresso maker.
The frame on the hob must be not too strong, and the mixture coarse but well pressed, with water at level tag, or you will get a weak coffee.
On Mokas a good strategy is keeping hob at minimum, and turning up the flame at top when coffee starts coming out.

French and turkish cafetieres:

Ensure that you put enough coffee, water hot enough, and that you left the infusion enough time to get a strong coffee.

Note: insufficient pressure and clogged lines on electric machines never give you a weak coffee, exactly the opposite.
Not pressed mixture always gives weak coffee, but too much pressed mixture may give you coffee with bad taste.

SOURCE: Coffee is really week

Check the sprayhead, make sure all holes are clear, then check the grind on the coffee it might be too coarse, and also check the amount of coffee being used, you need about 2 to 2.5 ozs.

My Jura Capresso F9 keeps making coffee when no one is pushing the buttons. It is always a big cup, mild. Any ideas what could cause this, other than a ghost who likes weak coffee, as my 5-year-old...

Apparently after a few yrs of use the steam wafting up from a cup of coffee works its way into the electronics touch screen mechanism causing it to turn on by itself...since moisture is such a good conductor for electricity it seems like there is a "ghost in the machine"...credit "The Police" band for that quote...my simple solution was a 6-7 dollar desk fan purchased from Walmart and point it up across the front of the unit...problem solved!...just keep the fan running while you use the unit and save a bundle of $$ not having to send it back to Jura!...Bob in SC

Where can I find an Jura Capresso Impressa F9 replacement lid

The only sources I have been able to find are in Europe. They do not always wish to ship to the US however. In the US the dealers always want the repair, but seldome wish to sell parts outright. Try this website for parts.
