This means the water cannot flow through the machine. Normal fix is to
prime the machine (turn water dispenser on, fill a cup) or descale the
machine. Go through the menu, select descale, enter, then turn the steam knob fully anti-clockwise. You should put the descaling solution in the water tank first.
If you have the auto-descale in the menu then run it. Run the solution through the machine twice. Then rinse well.
The following procedure works when you get the ventilate error:
The Ventilate sign can be due to one or more of the following reasons: Cause 1- Water leaking from the inlet valve below the water tank. The hose from the inlet valve to the pump can be air locked. When using the hand pump, do not thrust its nozzle too deep Cause 2- Blockage in the passage of water due to clogged passage anywhere between the pump and espresso delivery nozzle. Cause 3- Pump is not working. Open steam/water outlet knob and hear the pump work. If you do not hear any noise from the pump, this may be the main cause. Cause 4- Flow meter is faulty. This part is like the water meter for homes. It measures the flow of water and signals the electronic board. The malfunctioning flow meter will not send signals even when water is flowing through it. Cause 5- Hose is disconnected and water is not flowing in the system. Cause 6- O-rings at hose connection is leaking, reducing the water flow to be sensed by flow meter. Cause 7- Boiler gasket is leaking. Reduces flow of water through the system. Cause 9- Brew unit is blocked, blocking flow of water through the flow meter. This also causes pump to slow down and ultimately stop with muffled sound within 15 seconds. Cause 10- Brew unit not connecting brew valve, preventing flow of water. Same sign under cause 9. Cause 11- Steam is leaking. Registers reduced flow of water at the flow meter. Cause 12- Solenoid valve is blocked or solenoid coil is bad. Same observation as cause 9. Cause 13- Electronic Control board is bad. Though rare it can happen due to condensed water from leaking steam. When steam is leaking or boiler is leaking, machine should not be used any more to prevent steam shorting the Electronic board. Some of the above causes can be checked and corrected before seeking technical help. Do not assume anything without physically checking each of the following: 1- Make sure the water tank is full. If the water tank has water level float, make sure the float is in its housing and it floats as water is filled in the tank. If the level float does not rise with the level of water, then replace the float. 2- Water is not leaking from below the tank. The inlet valve is good. If leakage is present, replace the gasket in the water inlet valve. 3- Prime the machine by opening the hot water knob for 20 seconds or pressing the hot water button. Hot water flow shows the boiler is not blocked with minerals and pump is good. The solenoid valve is good. 4- Water & steam flowing normal, check the brew group for blockage. Determine when was the last time brew group was cleaned. Clean the brew group as explained elsewhere on these pages. If the machine has pre-ground function, try making a fake espresso (without coffee). Make regular espresso in other models to make sure that water goes through brew group and espresso is dispensed. 4- If hot water does not flow because the pump is not activated, then pump is bad. Replace pump. 5- Pump starts to work but within few seconds its sound is muffled and finally stop. This indicates there is serious blockage in the water line or the boiler is clogged with mineral deposits. If water is leaking and seen on the counter top, the chances are that water is leaking from hose connections(replace O-rings) or the boiler is leaking from seams (replace boiler). 6- Prime the machine by opening steam outlet for 20 seconds. Steam flow shows that steam boiler / steam outlet is not blocked. If the steam does not flow, then steam boiler or steam passage is blocked. Replace steam boiler or steam valve 7- Check the solenoid valves to make sure that they open & close as the coil is energized. Solenoid valve is located between the pump and boiler. The pump is activated simultaneously as the solenoid valve when espresso selection button is pressed. Some models may have a solenoid valve near the steam valve. In these models, the solenoid valve is activated to allow passage for steam/hot water. If the valve is not functioning, the ventilate sign will appear. 7- Hear the pump work when priming the machine. Louder noise from the pump can be due to ** air-locked water hose, or ** water is not sucked from the tank or the pump is sucking air instead of water or ** the diaphragm inside the pump has lost flexibility and not developing pressure to push water forward ** the hydraulic system is blocked at one or more locations due to mineral sediment. Find the location and cause of the block and correct it. ** Clean the brew unit (see cleaning instructions) and make sure that a- the ground coffee used is not powdery fine. b- The dose of coffee grounds is not in excess specification c- check if there is blockage. Find the cause and remove it. 8- If steam and hot water flow is normal, but the ventilate sign persists, then the flow meter or the electronic control board is bad. Replace flow meter or the control board, as necessary.
Try also the following:
Press hot water button once. Message on the screen will not change, this is normal.
Open the steam knob and allow the water to flow freely from steam wand into a cup. The screen should now read "Hot water,ventilate", you may need yo empty several cups of water before message changes. In some case it is necessary to refill the machine container without interrupting the operation.
As soon as the screen displays "hot water," turn the steam valve off .
If the machine warms up again, then problem is fixed.
There is an economizer valve on the machine that needs to be adjusted. I will assume it was pumping hot water, this is not a new installed machine, then the machine has scale buildup that is preventing the hot water from leaving the boiler through the tubes to the solenoid, only the mixed cold water is being dispensed. If this is a new installed machine, adjust the economizer on the boiler, remove the left panel for access. Big nut on the boiler you will see where it connects to the solenoid.
The boiler is contaminated if the smells funny, if not then the water is leeching the minerals out of the boiler. RO water is an acid (pure water), it is just as bad as distilled water for espresso machines.
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.

Clean the chamber below the white plastic valve, there is also a small discharge that leads from there into the drain tray clean that hole also. Second the thermostat that controls the steam may be damaged or the cpu board, the contact the controls the steam may be damaged, i have seen both of those happen on some units.
Some models have an economiser valve, which mixes hot water from boiler with cold from inlet line, that could be closed or obstructed. The line from the boiler to the solenoid or the pipe inside the boiler could be blocked.
