We cannot get the tray open to dump the dirty water and the used coffee. To open the compartiment on the right side to get closer to the tray from the inside needs a screw driver with a really odd shape (round at the end).
Do I have to open the compartiment? Where do I buy a screw driver that can achieve that?
If I don't need to open the compartiment, what else can I do?
Sometimes the tray sticks and just needs a good jiggle. Once you do get it open, clean the sides really well (it's probably got some junk on the sides making it sticky) Also, if there is too much water/coffee in the trays it can be hard to open because of the weight

The passage of water is not passing through coffee grounds. The coffee powder is dumped dry & water is bypassing the brew group and draining into the tray.
1- Machine was not descaled. or descaled with automatic method only, as suggested by Jura.
2- There is accumulation of Calcium in the hydraulic system, generating back pressure. This reduces the pump pressure and water cannot force its way through coffee grounds.
3- Stop using filter cartridges. Turn the reminders off.
hi , sounds like the dump valve solenoid has failed or the valve on the base of the brewer has failed probably stuck,.which is the more likely culprit. let me know if you require more in depth help.
its not a problem that can be resolved by a novice.
Dredge drawer is the big box on the bottom right. That is where the grounds are dumped. Remove the drip tray and pull the drawer out about half way. Push it back in with 1 finger on the right side of the drawer. That should clear the message. If it comes back on when you put in the drip tray, there is a section of the drip tray that can be removed to stop that. On the right side of the drip tray is a notch. Inside that notch is a thin piece of plastic. It curls up on the right side. Cut out the piece that curls up (just the piece that curls, about an inch). When you push in the drip tray that curl lifts the dredge drawer and knocks it out of position.
We had similar problem on our Z5. It turned out to be the two prongs at the end of the tray that were shorted out with dirty water. After carefully cleaning the whole contact area of the tray, the message was cleared. I would also inspect the machine itself where the prongs go in. Use a flashlight to ensure there is nothing causing the tray to misalign with the contacts. Somtimes used grounds gets stuck there and lifts the tray a bit.
The connectors at the back have liquid on them use a lint free cloth to remove the liquid and the tray fault will go away. If you want to prevent this make sure that when you pour the water out the tray you pour it out the side not the back and this is how the liquid or debris gets stuck there
Press the little button on the bottom right of the ice maker and clear the tray of ice. The maker has to be turned on for the tray to tilt and empty. This corrected the problem for me. The freezer side may have been left open and and the ice maker filled the tray while the door was open, I suspect.
I was able to order the ice tray myself and install it in the fridge - it's not hard. I ordered from one of the parts sellers linked to at the LG website, not those listed in other posts here.
Here's how to replace the tray:
You need to remove the tray dumping mechanism to do this.
Remove the ice bin, set it aside (don't forget to deal with the ice melt).
Turn the ice maker off (LG says to unplug the fridge, I didn't).
On the left hand side of the ice tray dumping mechanism there is a screw helping to keep the entire thing suspended from the ceiling of the freezer. Remove that screw- don't worry, the mechanism will stay put for now.
The dumping mechanism can now slide forward- note that you can't completely remove it from the freezer yet, but slide it forward and it will no longer be suspended from the ceiling. Don't let it drop or hang.
You need to disconnect its power supply now. On the left hand side you should see a small bundle of wires coming from the back of the freezer to the dumping mechanism. It connects to the dumping mechanism's set of wires with a pair of white plugs. Pull these plugs apart. You may need to pry the catch on these plugs apart while you pull.
Now you can take the dumping mechanism out of the freezer (and close your freezer).
To remove the ice tray you need to slide the housing that contains the rotating motor out of the housing. This is on the right side of the mechanism. If you have trouble identifying it look at the underside of the entire thing and you'll see a small "test" button. That button is on the motor.
To remove the motor you'll see two catches on the right side- you'll need to pull these catches out without breaking anything. You'll be able to slide the motor down and out when you get it right.
Sliding the motor out lets you get the old ice tray out now. There is probably a set of white wires routed through a little catch on the old ice tray that you'll need to free.
Put the new ice tray back on the motor. You'll need to get the left side secured at the same time you get the motor housing in its catches of the dumping mechanism.
Reroute those white wires back on the new ice tray.
Reconnect the electric wires to the housing.
Slide the entire dumping housing back onto the ceiling of the freezer and screw in on the left side.
That's it. You can press that test button on the underside of the motor. This will dump the tray and immediately refill it with water so you can observe if everything is working.
