Remove bottom front panel(remove 2-3
screws in the bottom) Pull bottom of panel out and down to remove.
the center bottom you will see the pump. On the front is a round thing
that resembles a filter. This is the pump filter screen...
Get a shallow
pan to put under screen. Turn lid counter clockwise to remove(turn
slowly and allow water to drain. As you may need to dump pan several
times before all water is drained out. Be careful or you could end up
with water everywhere. Once the water is drained pull out screen and
remove the debris and objects stuck in screen and filter housing you
should also be able to see the impeller on the pump inspect for debris.
Once everything is cleaned out reverse removal procedures put back
General alarm means the machine has detected a serious fault. There is a section in the instruction manual that may help. If not, read on.
Persistent "General Alarm"
This means many things. If the transmission is not stuck, check the main
boiler has not burnt out (open circuit). This happens when the
thermoblock labyrinth runs dry and overheats, a common problem caused by
leaks, limescale, milk blockages or water filter contamination. Replacing the boiler is the only fix, a difficult and expensive process, experienced fixers (or nothing to lose) only.
If the transmission is getting stuck there may be obstructions, the lead
screw may be worn or the limit switches could be faulty. If cleaning
and grease on the screw/bearings don't help then replacement is a tricky job only for confident hands. Approach with caution.
Here's how it works.... An initial short run of the pump draws water from the reservoir into the boiler where it is heated by an electrical heating coil. There are two outputs from the boiler, one from the top runs through a pipe to a steam valve. When the steamer handle is turned, the steam valve opens and steam is piped out through the steam tube for frothing milk. The second output from the boiler is on the underside and is stopped by the normally closed flow valve. When the water in the boiler reaches the right temperature, a sensor switches on the OK light. When the light is on, the user pushes the pump switch and more water is pumped from the reservoir. The pressure in the boiler increases because the pump is trying to push in more water and this forces the spring loaded boiler flow valve to open allowing hot water to run out. As the sump filled with ground coffee is fitted to the boiler output, the water is forced through the coffee and out of the sump where it pours into a waiting cup. When enough coffee has been poured, the user switches off the pump. The boiler pressure falls and the spring on the flow valve pushes the valve shut again.------------The first three steps aren't strictly necessary for disassembly however if you're using a long handle screwdriver then removing the base makes it easier to gain better access to some of the screws. Step 1. Remove the screw on each base arm. Step 2. ... then lift and remove the arms. Step 3. Remove the two screws on the base of the unit. Unlike in this photo I would recommend you avoid resting the machine on its back unless you are sure it has been completely drained. The black plastic base can now be pulled away allowing easier access to some of the screws that will be removed later. Step 4. Undo the two screws on the top rear. Step 5. Remove the coffee tamper by pulling and twisting. Step 6. Remove the three screws. These are anti tamper screws and are star shaped with a nipple in the middle. Step 7. With these screws removed, the top may be lifted away. The hotplate on the top section is still connected by a couple of thin wires so lift it carefully. Step 8. To help with shifting the top out of the way, disconnect the hot plate/boiler heater connection. This will allow you to push the top of the unit away giving you the room you need to get inside. Step 9. Unscrew the electrical safety earth and move the earth wiring out of the way. Step 10. Use some long nose pliers to pull out the circlip that holds the boiler inlet pipe in place. Pull out the pipe to disconnect it from the boiler once the circlip has been removed.Step 11. Unscrew, remove and clean the diffuser. Step 12. Remove the two screws . The black plastic underside casing can now be pulled away (plastic tabs need to be pushed aside ). Step 13. Pulling away the plastic underside once screws and tabs are removed. Step 14. Loosen the four black Torx (star shaped) boiler screws . Water in the boiler may leak out at this point so ensure the unit is upright and a towel is placed underneath. Step 15. Remove the four nuts (three arrowed) from the underside of the boiler unit. Step 16. Lift up the top of the boiler assembly along with the steam outlet and place to one side. The two halves of the boiler assembly are sealed with a rubber gasket which should remain attached to the upper housing. Make sure this is properly in place when reassembling. Step 17. The lower boiler assembly can now be lifted out. -------- to get more detailed help click this link directly.it has all the required instructions and pictures to disassemble the unit.the model number in the link is bit different from yours but the system is very same so it will help you http://www.r3uk.com/index.php/tech-tips/34-disassembly-guides/129-delonghi-ec710-coffee-maker-disassembly-and-repair click on the link above directly.

You need to reset it. Unplug machine, remove waste container and tray. Put the waste container back in without the tray and slide a knife under the waste container, close door. Plug in. It should reset. Turn off, replace tray and waste container and turn unit back on.
Easier, call their 800 number and they'll walk you thru it.
