Expel Air Our coffee machine continually displays "expel air" on the LCD screen. I have tried repeatedly to expel the air as per the instruction booklet but the problem still persists. Any suggestions?

I had the expelair problem with a CVA 620. I ran about 3 full tanks of water through the system trying to shift the air lock but to no avail.

First I cleaned out the brew unit. If you look down the funnel on the top of the brew unit you will see a philips screw in the center of a pierced grating. Remove this screw and carefully remove the grating, Not an easy task as this is at the bottom of the funnel. Behind this grating I found lots of coffee fat that had been blocking the machine. You can remove this fat with a cleaning tablet but removal of the grating will allow you to clean it more thoroughly. I used a small brush and a needle to clean out any blocked holes. Then carefully reassemble the unit.

Cleaning the brew unit didn't in its self remove the air lock but it will improve the future efficiency of the unit.

I contacted Miele and purchased some cleaning and descaling tablets. The machine cost way too much to risk using anything other than Miele stuff and they didn't cost so much. I then carried out a full descale. This takes a long time so make sure you have set a couple of hours aside to do this job. After descaling was complete the readout still said expelair. I then went through the expelair procedure and it worked.

I finished of with a cleaning tablet in the brew unit and still more fat came out. I didn't even know coffee had fat in it!!!!!

The machine is as good as new now and making great coffee. Hope this fix works for you too.

I have the same machine you have to hold the hot water button down and run the steam at the same time. However that is telling you the brass steam valve right above the steam dispenser is going bad.

The vacuum solution did for for me. Our coffe machine was not used for two years. In the last we tried many time to get some water out of it but we had always EXPEL AIR. I used the vacuum cleaner's hose sith a scotch tape around the water dispenser and after 12 times of pushing the hot water buttons the water came out.
Thank you so much. Carl

Expel air is a common problem, but if the manual's method doesn't work, it can mean only one thing, the pump is not working. You should hear the pulsing of the pump while in expel air mode. If not the pump or its circuit is suspect. The parts are SAECO and available without paying Miele's ridiculous markups.

I have almost the same problem ((but is coming hot water end steam but still message expek air what can be?

Used vacuum idea. put 2 layers of duct tape over end of crevice attachment of handheld vacuum. Then used ballpoint pen to create a small hole through the duct tape. Then placed steam tube into the hole (after removing the steaming cover). then turned on coffee maker, turned on steam switch (counterclockwise), turned coffee maker switch to "on", and finally pressed "hot water" button. after 5 seconds, hot water came out of both the steam tube and the hot water tube. THANK YOU!

Reason 1: air in the high pressure system
Reason 2: The pump does not work
Reason 3: boiler leakage or other place
Reason 4: The water flow sensor does not work

Even easier solution - take off the steam sleeve outer nozzle; then use your mouth to suck on the nw exposed steam vent (with the power off). Then run the normal expel air procedure.

Took 15 seconds (once we came up with the idea) and solved the problem.

Pump going bad. vacuum cleaner is fluke and temp fix

After doing some work on the machine, I found out that a little plasticthing sitting on the brewerunit was broken. If you take a look down into the "arm" on the brewer unit going into the machine. This where the water comes into the brewer unit when the brewer rises this as a part of process.
As said, in the hole here a plasticthing is sitting inside, pushing the ventil was lose.
I can set it in right possision to get my coffe manually, but it only lasts for some cups ....

I will contact the servicedealer to have it replaced....

Had Expel air problem a few times ! the first two times had been pushing the hot
water buttons many many times over and over again till water came out.
The last time i hooked up a vacuum cleaner's hose with a scotch tape around, turned the vacuum cleaner and after 4 time of pushing the hot water buttons the air was out and i got hot water coming out !!!!! Pass it on !!!

This is very common problem. Anyone has a suggestion how to get this fixed

I got rid of that msg by using the instant hot side on the left a few times (filled a couple of cups of hot water) and then running the steam test on the frother side until all the water came out & it was just steaming. Now mine says brewunit block and it has never been used... Wonder if I'll ever get my coffee now! Good luck.
