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.

Your dispenser spout needs to be removed and cleaned. It is getting coffee residue inside and the ports are getting smaller.

The oils in this mud cake dry up right after the water dries up (over night) and presto you have concrete! This concrete becomes too thick to clean, so cleaning with tablets has to increase dramatically if you increase the strength of the coffee. If you leave it strong clean it weekly.
Normally you clean the brew unit with cleaning tablets every time you finish descaling. That's about once every 200-250 coffees based on the water hardness you set in the electronics. If you notice changes in the coffee water flow speed it's usually from clogging.

If you're handy get your camera. Take pictures of every step you do. Remove the brew unit. Disassemble the left top section (2 screws holding the long pipe). It compresses a 1/2" long spring. It may get away from you so be ready for it. The spring attached to a half round plastic button (valve) that looks like a rivet. Clean all brown gunk from this valve and the housing and you're cr?me will return. While you're in the cleaning mode remove the filter and clean inside under the filter. The filter is that round stainless steel screen disc with the phillips head screw in the centre.
All this is evidence that cleaning needs to be stepped up, good luck!

How to check a miele novotronic anti syphon unit


During rinse, water usually flows through the softener dispenser. The cup fills up and a small siphon tube triggers a siphon action
which pulls the softener and water into the washer. This siphon tube is probably blocked with crud. See if you can pull a small cap like part out of the softener dispenser area. Clean both the inside of the cap and the hole under it. This will allow the water to flow into washer instead of flooding.

My miele coffee maker CVA 4070 dispensing tubes are clogged


I had this problem ... you need to remove the dispenser from the rear of the door. Then once removed clean in running water. Its a sealed unit but you can squirt high pressure water inside to dislodge the coffee sludge. When clean .. fill with water and make sure the 2 spouts drain evenly. regards

Coffee won't come out of the machine, tried cleaning out the tubes but that just made it worse


You need to advise the model .. but assuming its the CVA 40XX series ... the frist thing to check is the dispenser which has the two pipes comming out of the bottom. This can get coffee residue build up which usually causes 1 or both pipes to have reduced coffee flow. Indication that this is at fault are if the flow is uneven between the pipes or if coffee flows down the outside of dispenser. You can chck this pipework for blocages by openeing door and blowing air though the pipe extending on inside of door. The the dispenser is blocked you need to remove from rear of door and then clean out thoroughly in running water. If this pipework is not and

You need to advise the model .. but assuming its the CVA 40XX series ... here is what I would do;
1. First check is the coffee dispenser on front which has the two pipes coming out of the bottom. This can get coffee residue build up which usually causes one or both pipes to have reduced coffee flow. The indication that this is at fault is if the coffee flow is uneven between the pipes or if coffee flows down the outside of dispenser. You can also check the dispenser for blockages by opening door and blowing air though the pipe extending on inside of the door. The air should flow through easily. If the dispenser is blocked you need to remove from rear of door and then clean out thoroughly in running water.
2. Next check the pump and water path. The pump for the coffee is also used for producing hot water. So if the hot water is working normally then you can rule out the pump. If you not getting hot water then its likely to be the pump or a blockage in the flow through water heater.
3. If above OK then it's a fault with Brew Unit. Follow procedure to remove the brew unit, clean unit and test the air path through both pipes by blowing. Note: When you take out brew unit it not possible to access one of the pipes because its protected by a plastic shield. There is a manual procedure to manipulate the brew unit to expose this pipe so you can blow through it. However the likely cause is not a blockage in these two pipes but the stainless steel filter that the coffee must pass through. You will need an Allen key to remove the bolt holding this in place. Once removed you need to check all holes are free of blockage by inserting a very small wire in each hole. Alternately you can replace this part. If the filter is clogged then you should consider using a different type of coffee as some types coffees cause this problem and others do not.
I hope this helps. regards

Miele CVA4070 Steam flow through heater blocked


when you remove the cappucinotore, ( the piece that sticks down with the chrome tube and rubber pick up tube) from the door, do you still get no steam? that piece should be removed and cleaned daily. if you dont, I would imagine that it is completely blocked with old milk and would block off the steam.
