    yes. the gasket has been replaced before by my late husband, probably a couple of years ago. I will see if I have another one at home or if I need to order new ones.
    thanks

1.There is a rubber gasket inside the group head that can wear down with use and lack of cleaning. Try cleaning it well or replacing it.
2.There may be coffee grounds around the rim of the portafilter after tamping, which would disrupt the seal. Always make sure the rim is clean before attaching the portafilter to the group head.
3.The coffee may have been ground too fine. If the water cannot go through the coffee, it will move in other directions.

Espresso shots pour very slow for both the single and double shots.


Did you try adjusting the group head screw? And/or cleaning and checking the valve in the group head? Good visuals and instructions here: https://myprojectsandmods.wordpress.com/2014/10/27/delonghi-ec702-espresso-machine-no-water-flow-fix/

Making very bitter espresso. I already decalcified it and ran empty tanks through, without success.


Hi. The bitterness you have got is most likely to be dirty group head and shower. Remove the shower and clean with a steel wool. The group handle and filter basket will also have to be cleaned. Sounds like your using a dark oily blend. You cant use different blends unless you clean the group head every time. Same with the grinder. You can not use different blends for grinding. The different blends just cross contaminate, which can make your coffee bitter. Incorrect grind or wrong water tempreture can also make bitter coffee. Running descale does nothing for the coffee taste. Descale only cleans the lime/calcium in the boiler. Coffee does not pass through the boiler. Give your group head and handle a clean, and you should be right. Hope this helps. Dazza

SilviaWhen running wster thru group head to warm up machine, noticed foamy-smelly water. Ran more - now have almost black water with tiny black specs.?


You have huge corrosion and scale in the boiler. Your heating element will be fried soon. Boiler must be opened up and cleaned, element may be salvageable. USE ONLY BOTTLED WATER NEVER EVER TAP.

There is apossible restriction, but, whatever actuates the rrelease valve is what is actually malfuctioning.Depending on you level of detertermination, you can follow my approach to the dilemna if mass production. Since it doesn't work, find out why! Worse case scenario is the trash can, the best, A better understanding and working knowledge of the appliance. Screws usually hold these things together. Expresso machines are not inexpensive and there is a reason for those big bucks. No glue! So always taking the electrical part into consideration, there is no reason you cannot disassemble the unit and entertain yourself while at the same time learn something. Always take the approach that someone assembled it and you can disassemble it. If it does have glue, rhen it was anever intended to be serviced or repaired by anyone. So give it a shot and if you run into a problem, Give me a holler and we will keep moving. My ph. # is 909-630-3192.

No water through the head!!


I had the same problem - all water going down into the tray at the bottom - virtually none through the coffer basket. I couldn't find citric acid at the store to descale so I used white vinegar instead. I 3/4 filled the reservoir with warm water, and added about 1/2-2/3 cup of vinegar. I first ran water through the 'hot water' button (it comes out the steam spout). Then I ran the entire reservoir through the machine using the 2-cups option. It started running right away. I rinsed out the reservoir with fresh water, then ran a whole reservoir of fresh water through the machine to get rid of the vinegar smell. The first cup of espresso after this treatment was as good as ever. Phew! I thought we were up for a new machine!

Not making espreso all the time


Being that you just started using it I would not be concerned. You did the correct thing by cleaning the brew group. Check on your screen under total coffees. We usually recommend you change the brew group every 10,000 cups.

Make sure you descale the machine and you can try using the cafiza tablets to clean your brew groups internal passages.

Steam blowing out of group head


Were you using cleancaf to descale? If so, it is not a strong enough descaler. Use Dezcal. or a Dezcal cleancaf mixture. The two work great together.

Make sure you get some descaler in the solenoid area by turning on and off the coffee button.

Hope it works out for you.
