Question about DeLonghi Coffee Makers & Espresso Machines
It generates water or steam through the want which (I think) means that the pump is working and that the heater element is working. At times, the grounds are damp if I try to brew coffee. The rinse cycle doesn't run any water through. I've decalcified it and I've taken the infuser apart to verify that it isn't clogged. I've also pulled the heater assembly (heater and the attached yellow plunger) out and cleaned that as much as I could although I did not clean inside it. I'm stumped;( I got this used at an auction so I don't know any history about it. This is a 120v unit - some things talk about a 220v unit - don't know if that matters or not.
Sounds like the pump or its internal valve are not working. Check for voltage with a multimeter at the pump when it brewing. If voltage is present likely the pump has failed. Also check hydraulic pipes are clean and clear and that any filter screens are not blocked by scale.

on my machine, the two screws that attach the infuser receptacle to the insides of the machine came loose. You can see those two stainless hex socket screws when you remove the infuser by grabbing its two red tabs and pulling it out. Just use a hex shaft
screwdriver (size 3mm or thereabout) to tighten them.

I think you put the tubes on backwards to the flow meter. The inlet side of the flow meter is by the pump and the exit to the pump is by the water tank. They cross.

this is what happened to me, I didn't have the filter basket all the way down so the pot lid didn't open the valve that lets coffee flow so the coffee and grounds ran into the water resevior and plugged the filter, so I did the worst thing possible and took the filter out so the grounds got into the check valve that keeps the hot water going in the right direction. that makes it spit and sputter and brew slow.
after trying to flush it out forever I tore the metal plate on the bottom off and unhooked the rubber hoses (don't do this unless you have a needle nose pliers, you'll never get them back on) one should go to the brew head and the other is the water inlet, this has the check valve. you can tell which is which by blowing through them and seeing which one goes to the brew head. if you can blow through the other one the check valve is stuck open, I blew air into it with an air compresor and this forced the check valve shut and now it works fine. I know this is the same symptons as calcium deposits but I had cleaned it twice.
try flushing it with water first but sometimes it takes extreme measures

Husband suggests that could be coming broken off the brewing unit as it should be activating, He suggests you should get in contact with your local De'Longhi Service Centre (should be info on how to contact in your User Manual, or google De'Longhi for your country).
