Lack of water pressure

Hi just a tip from experience, grind the coffee fine and keep the spout ( where the coffee comes out) very near the cup, while making the coffee.

Hello,

I am an expert espresso certified man. First of all your repair man is wrong. Let me explain. If you are getting steam at all, then your pump is not broken. This is the way it works, you have water in your machine, it goes into a area where it heats the water by heating elements, then as it heats it builds pressure by air and heat. The machine has a water pump in it, that operates by of course electricity, it pumps the water that is heated by the elements through the machine to of course make shots of espresso. The steam part is simular as it goes in a area, the gets hot and produces steam from the water, like a iron would of press kind of method. THE MACHINE will not make coffee or steam if pump is not working. If you turn machine on, and hear it humming or running, when trying to make a cup, then motor is running, if you turn it on and try to make a cup of coffee or steam and hear nothing at all, then pump is not working. If your machine is leaking under machine from from the steam valve, means it would not do that if pump is not working. Sense it is leaking, this tells me it is clogged. Most likely your need your machine cleaned good, that means descaled. Clean hoses, use small needle to poke in end of steam wand to clean out good jet air holes and basket screen. Find your manual, and it should tell you how to properly clean your machine, and even can use can of compressed air, that you can spray in hoses. It appears to be it is clogged, and when the pump or lines are clogged , it will back up like a clogged toilet and flood area around base and underneath. This whole problem is a cleaning problem, do to a clog or build up. I hope this. PS no if you pump is out or clogged, you would not get coffee as it need to the pump to work (unclogged) to push the water through the heads. Thanks Mike

Hello Juneyjune,
These coffee systems have a series of small rubber 'O' rings that tend to crack from condensation over time causing your low pressure problem.
The 'O' rings are connected to a heater that looks like a horse shoe mounted in back of the grinding unit.
I would recommend contacting Miele technical services. They can have a technician come out to replace the 'O' rings or you can order them from the technical services rep if you know someone that can replace them for you. Just be careful. These machines operate off of 220 volts and that is no fun to get shocked by. I have been many times with this machine

Good luck!!!

if you have water out brewing without handle with coffee, than you check this 3 things:

1. how fine is grinded the coffe, is it too fine for your machine?
2. does pump make enough pressure to brew your coffee(you can measure if you attach an gauge to handle or steam pipe.
3. by any chance your boiler security valve opens too soon and dont let pump to get the needed pressure. (perfect pressure is from 7 to 9 bar)
   

It sounds like a heating element issue. Those elements look like a single unit but are actually made up of 2 or 3 independent heating coils - one may not be working. So, you're only getting 1/2 to 2/3 heating capacity, which isn't noticeable until the machine is under heavy steam load.

Hi, My husband found the problem and fixed it. Something had fallen into the water reservoir and was small enough to block the pump. My husband extracted it, now all is well. the Coffee Maker is fine now.

Hi,

When you try to get out water, can you get a full cup of water or just a half cup?

How often do you descale your machine?

I had the same problem, so I embarked on a search mission. Here's what I found, and it worked for me. First, these pots are designed to work only for the amount of water specified for each size. So I have a 6 cup pot that requires 9 oz of water. If I try to put 8 oz. of water, I only get about 1 maybe 2 oz of coffee. Size of the grind doesn't matter as long as you stick to espresso grind (some coffee grinders have several settings for espresso grind). As soon as I put exact amount of water, it works much better. Now, you have to understand that some water gets evaporated as steam, and some water should remain in the boiler section of the pot for safety reason. The general advice is to take the pot off the burner as soon as the gurgling sound reaches its peak and just starts to subside.
That may result (as least for me) in weaker coffee than I like. So what I do, is I fill the coffee funnel with coffee grinds, tamp it very lightly, and then using a wooden skewer I make 3 or 4 holes all the way to the bottom of the funnel. That will help the steam to escape. Before I learned this trick, I thought it was a valve problem or a seal problem. As soon as I tried this trick, bingo! I personally like strong coffee. So I didn't want to compromise it and start adding less coffee to the funnel. The thing is that steam wets and expands coffee grinds, and that may be enough to hinder the process. If you make several holes, steam will not be building in the boiler section and escaping thrgough the valve or break the seal on the gasket.
Hope this helps.

I read about others having the problem, and used some of their suggestions. What worked was to repeatedly hit the hot water button, open the valve, then close it when it said to. After several repetitions it worked. Since then, I have followed steaming with running about 4 ounces of hot water through, so their won't be air in the line. So far, so good--** problems today.

1. if it is fine ground coffee sometimes you get this result at machines.
2. low pressure pump = you get water from it but only when handle is out or steam valve open.
3. pump with non return valve broken = in this case you get water if you open tea valve during pump works. this pump can work long even she has 1 valve damaged, only when she is empty you need to open steam valve and leave pump running while you don't get water from valve.
