Easy repair, perfect parts and easy to find
My expresso coffee machine is now like new, changed a valve and the corresponding valve ring to eliminate a leak. Fixing it was a small fraction of the cost of having to buy a new machine. And the repair took less than 15 minutes!

Parts Fit and Repair Easy
I had ordered six parts and the repair was fast as the parts fit correctly. I would have given 5 stars except the green warning light (Part #: 512641) was actually orange, not green. Not a big deal for me as the light worked but perhaps the online catalog should reflect what the part actually is. This may be a slight concern id and when I order parts in the future.

The hardest part was reaching three screws which secure the top of the machine. It requires a star drive. All of the other screws are small Phillips heads. After you remove those and two on the back, the top will lift right off.
I promise, everything is very intuitive. Unplug the hoses by simply pulling on them, remove the pump by wiggling it off its rubber mounts and unscrew the water valve connected to the pump the pump. Replace those with the new ones and reverse the process.
I chose to change a few of the other little pieces of tubing, simply because I was under the covers - super simple and cheap.
I also replaced the spring and valve on the head (where the water comes out) to ensure that the new pump didn't overwhelm an old valve.
This pump works perfectly in our Delonghi EC702, it actually is an improvement over the original one. With these parts changed, we have a completely new machine!
Thanks eReplacement for the super fast service and clear parts catalog!

The machine's lower-boiler output valve was leaking before running a cycle due to the lower boiler being broken and the valve spring missing.

Less than 15 minutes
Tools Used
Screwdriver
1.) Used a 3mm flathead bit on a long, but skinny screwdriver to unscrew the top heating base from the machine via the black base that surrounds where the water outputs.
2.) Used a Phillips Head #0 bit to remove the two small screws on the back of the machine connected to the top heating base.
3.) Removed the top heating base.
4.) [CAUTION]If there's water still in the boiler, it will leak. If the boiler is hot, steam may exit, so let the machine cool down before continuing this step[CAUTION] Used an H3.5 (Hex) bit to remove the lower boiler from the upper boiler. It may also help to unplug the connectors from the upper-boiler for easier removal. Take a picture as you go to make it easier to put the wires back in the right places.
5.) After removing the upper boiler, remove the lower boiler.
6.) Grab the new boiler and put together the spring valve contraption. Place the valve ring inside the smaller end of the spring, then the valve, and carefully place the spring into where the dowel would go, with the valve going in first.
7.) Then screw in the dowel.
8.) Place the repaired or newly put together lower boiler back into its position.
9.) Screw the top boiler back to the bottom boiler with the H3.5 (Hex) bit. If you removed the wires, place them back in their respectful positions.
10.) Re-attach the top heating base.
11.) Screw the two small screws back into the back of the heating base with the PH#0 bit.
12.) Screw the three screws that connect the black base to the heating base with a 3mm flathead.

Espresso machine needed a new ball valve on the boiler outlet.
Dawn - May 16, 2021
Tool Type
Coffee Maker
Difficulty
Easy
Time
15-30 minutes
Tools Used
Screwdriver
My DeLonghi espresso machine was leaking 2/3rds cup of water about 15 seconds after turning off the pump, and the steam wand was operating poorly. I determined the boiler ball valve had broken into bits and was no longer functioning. I decided to replace the valve ring and valve spring at the same time.
Make sure the machine is not hot before starting.
1) With a Phillips head screwdriver, remove the screw in the center of the diffuser and remove the diffuser.
2) Using a flathead screwdriver, remove the dowel.
3) Remove what's left of the valve, valve spring, and valve ring.
4) Thoroughly clean the dowel and diffuser.
5) Turn machine upside down and replace the valve ring, valve, and valve spring, being careful to seat the valve correctly.
6) Replace the dowel by screwing it down with a flathead screwdriver. Screw in until just tight and then back off about a 1/4 to a 1/2 a turn.
7) Replace the diffuser using the Philips head screwdriver.
In addition I needed to descale my machine before it began operating as expected. My machine had sat empty and idle for several months and I believe this contributed to the degradation of my ball valve.

1. Removed water reservoir.
2. Unplugged unit.
3. Turned upside down on a table.

7.On the small end of the new valve spring I inserted the new valve ring. I then inserted the new valve into the valve ring. NOTE that the valve is made of silicon rubber. After inserting the valve, the rounded head is on top of the valve ring.
8. I inserted the completed assembly from 7. into the chamber or slot.
9. I screwed the large headed screw back in place.
10. I screwed the silver diffuser plate back in place.
11. I attached the water reservoir and filled with water.
12. I plugged the unit back in and turned it on.
13. NO MORE leaking water or steam, and the frothing wand was functional once more.
