Question about DeLonghi EAM3500 Espresso Machine/Coffee Maker
I have a model EAM 3400 expresso super-automatic. A couple of weeks ago after a regular schedule cleaning, the machine began dropping only about half the water through the infuser and into the cup. the rest appears to be leaking from somewhere inside the machine.
After each cycle, approximately half the water ends up in the drip tray from inside, or worse, on the floor of the internal compartment.
The machine has been fantastic for a little over two years, which coincidently is now two months out of warranty and Delonghi has stated they will not repair it (not that they could anyway; my god, FOUR service centers in the entire USA???)
It is a 1300$ machine and I really would like it back up and running. Someone told me there is a replacement seal kit and step-by-step instructions online for how to disassemble and reassemble the machine. If anyone knows about this I'm dieing to find out how.
Coffee leaking into the drip tray could be from the brew unit or the front door assembly. Water leaking probably means a hose connection to the boiler has failed. Don't just leave it, fix leaks immediately. Besides the electrical danger, the rust on working parts from long term leaks can be extensive.
Are you confident? Operate the machine with all covers off to see where the leak comes from. Be extremely careful, ready to pull the plug at any moment. Touch nothing inside! Burning, scalding and electrified! Check both boilers very closely while making coffee, most leaks become obvious on close examination.
Most leaks are due to failed o-rings in the connectors at the end of the teflon hoses, usually at the coffee boiler. Replacing the o-rings should stop the leak.
Source replacement o-rings. Slide the hairpin c-clip out of the side of the white connector and pull the teflon hose out. Fish the old o-ring out of the connector with a small hook or point if it didn't come out with the hose. Place the new o-ring over the end of the hose, snug against the brass collar. push the hose back into the coupling being careful to go straight and true so as not to damage the new o-ring. Some force may be required, be careful not to kink the hose. Blunt needle nose pliers to push the rear of the brass collar usually does it. Replace the c-clip and test for further leaks before reassembling.

Mine started leaking too. I took the machine apart and cleaned everything. (if your at all mechanically minded it is very, very simple to take apart). Still leaked. I ended up leaving the top off the water dispenser and the leaking water goes right back into it! Don't know if your leak is that "lucky". Just thought I would share.
