La marzocco gb5 left group is leaking water constant... how to stop

The hissing inside might be a leak from the vent valve or the level probe connections to the boiler. The leak from the middle if it is not the paddle version or group cap version then the plunger in the solenoid needs to be replaced. If it is the group cap version the plunger in the solenoid and or the gasket inside the group cover might need to be replaced. Before you open the group cover make sure you have replacement parts. You will need H1006, L103/A and L103/B and L100H.

My Saeco Incanto Sirius machine keeps asking for yet another VENTILATE cycle

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.

Ventilate error -

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.

Espresso machine HISSING!

It sounds like you have the cup warmer turned on. But if that's not it there is a leak in a connection coming from the bolier. If you open it up it will be obvious where it's at. Don't wait too long because the moisture will effect the electronics.

Ventilate!....shows in window and machine will not ventilate when knob is opened. it has regularly been de-scaled but we do live in a hard-water area.

Generally you can clear the ventilate error by pressing the button for Hot Water and then opening the steam knob. You should hear the pump run and water should start to flow from the steam wand. If it doesn't, try removing the frother nozzle so just the chrome pipe is showing.

To remove the frother nozzle you slide the outer sleeve off, and then grip the nozzle with one hand while twisting the cap to loosen it. Then it should slide off the metal steam pipe. Or you can check that the tip of the nozzle isn't clogged.

If you have the frother removed and the steam pipe is definitely open and not clogged and you still hear the pump running but no water is coming out, the next step is to prime the pump.

If you still have the squeeze bulb pump that came with the machine, you can use that - or if you don't have it, a turkey baster will work. You want to take the water tank off and set it aside, then pump water into the valve in the center where the tank had been sitting. You choose "Hot Water" and open the steam valve so the pump starts and then pump water into that valve with the Turkey Baster. You should hear the pump catch and start to move the water - when this happens immediately close the steam valve so the pump stops - then replace the water tank (filled with water please) and open the steam valve again and let water run out of the steam wand for several seconds.

That should clear the ventilate message.

Ventilate shows, nothing works

There is an air lock in the hydraulic line of the machine, thats why it is calling for ventilate, if hot water valve is open and it is still calling for ventilate, then it is possible that the valve is blocked, it might be at top of the wand or at the tap rod assembly.

Nead help pleace

When it says to ventilate, it is asking you to prime the pump. Put a cup under the panarello wand ( the steamer/frother) to catch the discharged water and press the hot water button (upper left button on my machine). Wait until air stops coming out with the water, usually 3-5 ounces, and then press the hot water button again.

You machine is now ventilated (primed) and should be ready to go.

Saeco Magic type sup 012 problem

Hi sad_loser
Your problem is easier. On the top left side of the brew unit is a thumbscrew that holds the filter screen in the brew head. See if you push down on the thumbscrew you can get the filter screen to move? If it dose pull down on the filter screen and see if it will come out. If it does there will be an extra nut on the screw end and that needs to be removed and you need to order a new thumbscrew. That is why we call it a thumbscrew. It only has to be finger tight. The key is only for removing.
