Question about Miele Coffee System

Replace Water Tank

We've had our Miele water tank leaking in the machine bottom for several months. We constantly get "Water Fault Failure" readings and have to use a turkey baster to remove about 3 or 4 cups of water from inside the machine! Had it serviced twice and they replaced the washer inside the machine, but nothing to do with the tank itself. It's happening again and we do not want to pay for one more service call! We just want to replace the tank itself and see if that fixes the problem, but cannot find this separate part ANYWHERE! This is for a built-in Miele Coffee System that is almost 9 years old. Any ideas??? Thanks!

Connie .. I have a 4070 and I suspect yours is the earlier model (CVA615 ?) and so I'm not so familiar with this model. Nor have I had a water leak like this. Before you buy any parts you need to establish the source of the leak. It could the seal where the tank engages with the unit or anywhere downstream of this in the water path. Replacing the tank may be expensive and may not solve the problem.
Connie .. I have a 4070 and I suspect yours is the earlier model (CVA615 ?) and so I'm not so familiar with this model. Nor have I had a water leak like this however its likely to be an o-ring seal. Replacing the tank may be expensive and may not solve the problem. So before you buy any parts you need to establish the source of the leak. It could the seal where the tank engages with the unit or anywhere downstream of this in the water or steam path. If you're NOT TECNICALLY QUALIFIED you should call Miele and make sure the water is present when they come. I'm technically qualified and have experience working on mains voltage appliances and so I would attempt this service as follows. 1. Locate mains supply and disconnect appliance. 2. Remove appliance from kitchen unit and place on table. 3. Remove top and rear access covers taking very careful note of where each screw comes from. Note: You must replace each screw to its correct location to ensure the machine is properly earthed/grounded. 4. Remove all water from bottom of unit. 5. Re-fill water tank and leave for a day or two (no power connected). 6. If water appears at the bottom then you need to locate the source by inspecting the water path. 6. If no water appears then you know it's a problem when water is pumped around the machine or steam is generated. To test the next stage replace all covers, leave on bench, connect power and use as normal. Note: NEVER CONNECT POWER TO MACHINE WITHOUT ALL COVERS IN PLACE AND EARTH/GROUND WIRE CONNECTED. After making a couple of coffees, check to see if water has appeared in the bottom and then turn off machine, disconnect power and remove access covers. Trace the flow of water to the module or seal that is causing the leak. The above tests should pin point the source of the problem and what parts need to be replaced from Miele. Regards

SOURCE: need to buy water tank for miele coffee


spares are only available through Miele spare parts or their registered service agents who will probably then source the part from Miele spare parts anyway.

My Miele washing machine has leaked everywhere, it said waterproof failure and now there is a tech fault code F224.

This leak should have filled the bottom tray and tripped the float level switch, this shutting down the machine. Once everything is dried up, you need to find out where the leakage is from. This really means removing the front door assembly in order to view the hoses and drain pump for instance. Without knowing the machine I cannot add more detail but you will need to investigate further. The leak should have switched off the electrical supply to the machine via the solenoid operated water inlet valve that is the anti-flood system. If this has not operated then it suggests that the water supply to the unit has caused the flood.

Why does my water container fill up even though my machine is plumbed in?

This looks like a fault. The plastic tank has two reed switches that measure 'tank empty' and 'tank half full'. When the tank is empty the inlet solenoids (there are 2 for safety) open and water enters the tank but not so much to fill the tank to the half way level. In normal operation the level water in the tank will drop and then more water is allowed in. In your case it appears the 'half full' reed switch is being activated because the solenoids are not closing off properly and water is leaking in and filling the tank. If you do not empty it then eventually it will fill and leak into the leak. The problem can be caused by either low water pressure (below 145 psi) or sticky solenoid. If is the solenoid then the Miele solution will be to replace both solenoids. Alternately you may be able to remove, take apart and clean. Also check that you have a mesh filter at connection to tap. Also you can temporarily fix the problem by turning off the water at the tap and re-programming machine to 'turn off' the plumed water line. regards

Water system fault is the readout on the window

Water leaking inside the coffee maker. Remove water tank. Use a turkey baster and place it inside a hole, where the water tank houses into. **** water out, which is causing your fault message - "Water System Fault." Only thing you can do is make sure water tank cover/lid is put on properly (correctly oriented) and replace seal ring where water tank spout inserts into. If problem returns, then there is a serious leak inside the unit.

Miele CVA 610 coffee system says "water system fault" can I fix myself?

Hi I,am not 100% familiar with this model but the machine thinks the is a leak. Remove water tank the should be a hole visible under tank place finger in hole and check for water. If so remove water with syringe etc. Leak most likely cause tank incorrectly fitted or faulty seal on tank. If water tank seal OK, Remove water with syringe etc appliance will work. As a precaution remove lid and run you should be able to see any leaks. If not look for white stains on components. If no leaks or stains found it's was most likely tank incorrectly fitted.

Miele coffee system CVA 2660 is showing fault #10 while I descale and won't let me finish the program. I restart the program by turning off the system but I get the same fault message after about 20...

F10 is a water intake fault. The are several possibilities: the pump may be defective, a piece of lime scale may have blocked a pipe, the water tank might be faulty. Most likely is the pump.

Miele coffee system cva 615. Message: Water System fault. What can I do?

More then likely there is nothing wrong with the water seal but simply the tank was not placed properly over the seal and water was bypassed to the reservoir. If a significant amount of water sits in the reservoir the "Water System Fault" trouble will appear and stop operation. The easiest way to remove the water from the reservoir is with an inexpensive ($5) siphon tool available at any auto parts store. Once the water has been removed and you can operate the machine and it goes through the "Warming" sequence you will receive a "Air in water System" alert. Follow the simple directions in the manual to correct this trouble and your system is back to normal. I have heard people have been charged by technicians up to $600 to fix this trouble and told the seal had to be replaced. Just take care when placing a full water tank back into place and enjoy : )

Water leaking from under the machine (Miele G638 Plus) dishwasher

The salt tank is a pathetic piece of ****. The plastic cracks and leaks into the bottom tray, which in turn sets off the safety switch.
Follow the attaching hoses and bypass the salt tank unless you really need it. This will save you around $250 for a salt tank and $300 labour for callout and repair.
