Question about Miele Coffee System
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

there is a liltle floating black thing at the back of the container, this works as a magnet switch. see if it is there or is stuck and doesnt raise with the water level.

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.
