I knew the paperclip trick, I tried the air shot to reverse the flow of water. After running Vinegar and water through and letting sit overnight. I tried the air blast then make a cup, another blast X 4....though I get a good flow through the K-cup area, I still only get 2/3 cup of water.
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.
Take the cup warmer off the top and find where the water line comes into the machine, follow this line to a tap that has a screw in knob. If you turn the know clockwise it will slow the flow of water to the hot water spigot.
That means the pump needs to be primed by running water through the wand. Push the water button and open the knob on the right. You will hear the pump change tone when it primes and the light or message will disappear. If you have a restriction in the intake line the message will not go away. There is a flow meter inside the machine that measures water flow. If the flow meter does not spin when the pump is running, the computer thinks that the pump is not primed. Coffee grounds will get into the intake and restrict the flow meter. If you get a restriction in the water intake (below the water tank, on the machine) the pump may run and water comes out, but the flow meter does not create the jet of water to spin the turbine wheel to send impulses to the computer. You get the ventilate message. One thing to remember is when you are working on the water system (have the water tank off) do not fill the bean hopper and visa versa. Keep them covered when working on the other. Cross contamination will damage a machine fast

The valve parts need to be replaced, if it is only happening when brewing coffee then there is so much pressure on the pump that it is forcing the valve open. First try adjusting the amount of coffee be added to the chamber for brewing.
This may help if you have not tried it yet. Adjust the water flow by turning the small knob on the front of the dispenser. the middle setting has a dot. turn full clockwise for stronger full left for weaker.
You might need to prime the pump manually since the machine has been moved.
directions: Fill water tank. Turn power on. Open the steam knob all the way. Press the coffee button. Put a cup under the steam pump wand. Wait until you see a steady flow of water and no air. When you see the flow of water, close the steam knob. Turn off the coffee button. Now the machine should be ready to brew an espresso.
