You can buy some Miele Descaling tabs on Amazon aprox $21 and run the descaling program.
That's what I do to get it clean.

Hope this helps

You may have abandon the repair effort and purchase a new replacement.

The scope of electronics on that unit would need to be serviced by a authorized personnel . Take it back to the store for a refund, or purchase a new one. AC

This things are very temperamental. They use air pressure to move water around. There are no filters in it.

Brew group blocked is normally displayed when there is no water flowing through the brew unit. Remove the brew unit and use a small screwdriver(make sure machine is off and cooled), then gently lift up on cross section fitting on white plastic valve inside the machine, if water flows out it works, now we will plug in machine keep brew unit out and turn it on and press fitting in again, if water flows and pump kicks in and water flows out from valve and not under machine you are good, The coffee grind might be too fine and needs to be adjusted to coarser.

If the portafilter is coming out when brewing your brew head gasket needs to be replaced. If you have never replaced your brew head gasket its way beyond time. They should last about 3-4 years at the most. With a good brew head gasket the portafilter should be easy to lock in, not requireing a lot of pressure to force it over. Try replaceing the gasket first before you invest in a new portafilter. If you really need one I have some and the gaskets.

The red oring on the brew unit needs to be replaced or lubed as does the track on the unit it needs to be cleaned of coffee grounds and lubed.

Malfunction 8 is related to the brew unit typically. It is usually an indication of the brew unit motor having to work too hard to move the brew unit up and down. This is usually cured by disassembling, cleaning, replacing any o'rings that may be bad, and lubricating the unit, then reassembly.
I have had to do this twice on an an E75 and an E8. I finally broke down and bought seal kits and food grade lubricant for doing this. (I have only been able to buy parts from Europe online) One could by a new brew unit off of e-bay and change out the whole thing. But a simple cleaning or rebuild will typically suffice. One note. The cleaning tablets tend to strip the lubricant from the inside of the brew unit over time. Ocassionaly the seals in the brew unit will fall apart and bind up the unit. Either of these is usually accompanied by a sound of the brew unit motor straining to cycle the machine. If you are not savy in repairing it you may want to send it in. I suspect they will tell you it needs a new brew unit aand quote about $300 USD for the repair. About two hours, much patience, and about $10 in parts is most likely all it may need.

You can purchase the brew group lubrication on our website. The orings for the panarello are not available and you would have to purchase the whole thing. You can also find panarello's on our website. You may not find the exact one, but most of them are the same size.
