It sounds like the connector or wiring that links the LCD display board on the door to the main PCB inside the coffe maker has become loose or damaged.
This would cause the text displayed to become scrambled.
Its a 26 way connector that is labelled JP16 (on the next model up) and is next to a large IC.

SOURCE: Miele cva615 says "brew unit

Hi, possible that there is WEARING OFF of the bushes in the shaft of the grinder jar section or to the motor section. If you can try to hold the spindle and move , there must not be any play of the shaft nor it must be TOO free. If so the bushes must be reset with the same type. Also check if the motor bush/bearings are faulty or a drop of light grease or oil might give a temporary relief.

Or else you have to get a another one....

Miele cva4070 coffee maker showing fault76


Fault 76 is caused by there being too much coffee to compress . Assuming there is not a fault with brew unit or brew unit drive, then try to use less coffee (see menu settings) or grind the coffee to a finer level (see manual). regards

I have miele CVA 4070 It just recently started only brewing about 1/2 to 2/3 cup of coffee or espresso and the rest of it goes into the waste container. So the waste container has a watery puck and...


Have you clean the brew unit with the cleaning tablets? This dissolves and rids the brew unit of the oils which in turn build up and clog the brew unit - the result being watery pucks and less product being disbursed.

You should be able to, If you can remove it and providing there are no Electrical parts, then soak in a white vinegar and water solution.
Or a Descaler.

Can't have two coffee in a row...


I had the same symptoms, except in my case coffee would sometimes not be produced irrespective of whether 2 coffees were selected. Over a period of a few weeks the problem gradually got worse. When coffee was not produced, the coffee grinds in the waste container would be dry, indicating that hot water was not being forced through the puck. The problem in my case was the o-ring on the back of the brew unit was no longer reliably sealing the path from the hot water pump through to the puck, resulting in the hot-water being expelled directly into the drip tray and no coffee being produced. To fix, I removed the brew unit and replaced the o-ring on the back of the brew unit (3 minute task). Note: This o-ring is the most stressed in the entire system because it must withstand the high pump pressure as well as being inserted/removed from the hot water outlet each time a coffee is made. No other seal has to perform this task and Miele have obviously used a very high quality o-ring because this lasted 11,000 coffee cycles in my case. I would strongly advise you buy the Miele o-ring (about $4) and to also regularly cover this o-ring with the Miele grease (or other similar food grade grease). Also the old o-ring looked fine but this is deceptive. On close inspection I could see the old o-ring was a flattened on the outer edge and this was enough (given the high pressure required to force the water through the puck) to allow water to get past the o-ring and bypass the puck. In retrospect, there were other much earlier symptoms of the failing o-ring. Firstly when the brew unit was removed, the opening in aluminum panel to the brew unit drive would always be soiled by wet coffee waste, caused by coffee waste being forced back down the hot water pipe and escaping past the 0-ring seal (Note: Miele have designed the unit so that when the o-ring fails the water and coffee still return to the drip tray however it still creates a mess in the back of the machine. If it's really dirty then you need to remove brew unit drive fro cleaning and that is a significantly more complex task). The other symptom was that the coffee taste was not ideal and this is caused by the insufficient pressure being reached during extraction. So once I replaced this o-ring the coffee taste improved and the back of the machine was bone dry. I suspect Miele replace this o-ring every time they service these machines irrespective of symptoms because the cost is low and the impact of a failed (or failing) o-ring is significant. Regards

I have a cva coffee machine it seems like the brew unit is jamed it makes a buzzing noise like it is descaling itself , I have cleaned it and checked the shoot for alignment it makwes the noise and then...


F73 is a bad brew unit. The cva 4070,4075,4060, and 4066 are designed to use espresso beans.
If you use an oily bean such as Starbuck's french roast, it will clog the filter in the top of the brew unit. If you catch it in time, you can just replace the brew unit. If you run the machine with a clogged filter long enough, you have to replace the brew unit and gearbox together.
Sometimes if you work with the tech support department, they will send you a brew unit to install yourself. If you live in an area that has Miele factory support, you may just want to get a service call. It is very important to rinse the brew unit every 24 hours, and to use the cleaning tablets in the trap door( not the descaling tablets) if not, the coffee oils build up and turn into a tar that will clog the brew unit. They run about 300 dollars so they are worth doing the maintenence on.
