We noticed that there was less & less water/pressure for the espresso for awhile. Now, when you switch from the frothing/steam wand mode to espresso, it sounds like is always has (loud pump sound), but no water comes out at all. Is there a way to fix this, or is the machine shot? We've used it every day for about 3 years.
I have found that I have to remove the group valve assembly about once every 1 or 2 months to clean out the .030" to .040" opening in the valve body. The manual gives instructions on how to do this. It becomes clogged with a thick paste like substance.

Good question. I have been surprised before today after checking the manual for various gadgets. There are thousands of manuals online which can be searched for if it is missing. We have a bench top water filter fitted. When you have one of those, the difference is so noticeable that you will only want drinking water from there

First thngs first, make sure knob is turned to 2, then make sure there is water in the boiler, then turn machine to 0, remove back panel and reset thermostat on top of back boiler, if your machine has that feature installed. Then turn machine to 2, open one of the steam wands, If within 10 minutes boiler does get hot or there is no water bubbles, from steam wand, then the pressure stat might be damaged and needs to be replaced.
The pressure is from zero to the opening pressure of the OPV. This should be about 10 bar when the OPV is cold. When the OPV is hot, the OPV spring is hot and a little more flexible. The OPV opens at about 8.5 bar when hot.
When the wand valve is open, you can get a lot of steam or water with not a lot of pressure in the boiler.
Take the lid off the reservoir and watch the hose from the OPV. It's the short hose.
Pull a shot with less than usual coffee in the basket.
If you see water flowing from the hose, the OPV opened.
If it did not open and there is little extract in your cup, buy a new pump.
The "frother" is probably blocked. Remove it and see if you can blow through it. If not, you can try cleaning it with a paper clip. If that won't work, place the metal frother tube in a pot of water with a bit of ammonia or vinegar in it. Heat the water to boiling, then let it simmer awhile. After it cools, try using the paper clip again. You should clean the steamer attachment after each use: 2. Remove the froth enhancer and rinseunder warm tap water.3. Wipe the steam wand with a damp cloth.4. Briefly set the Selector Control to the‘STEAM’ position to clear any remainingmilk from the steam wand.
The steam wand has to be removed to be cleaned properly. Unfortunately, this procedure is not outlined in the manual. Just cleaning the wand on the outside or using a clip to clean the tip is not enough.
The other end of steam wand where it connects to the pressuring cabin actually swivels around a fitting. It is this fitting that you need to thoroughly clean. Years of using the machine can cause calcification around this fitting.
If you look under this end of hte steam wand, you should see a philllip-headed screw. Before you loosen this screw, you have to remove the grey trim so that the entire wand can be remove.
Once the entire wand is removed, what I just described will be much clearer.
security valve of boiler openes to early and dont let the pump to rise pressure enough for good brewing( if it is this you can see water returning back to container if you have 2nd pipe in your machines reservoir)
