Wont steam, can't froth


Hi. Id say your steam thermoblock or therostat is faulty. Can easily be checked with a multi meter. Just follow the steam outlet back to the various componets, if you can. You also will most likely have a leaking steam tap on this model. You'll see where the valve has been leaking when you disassemble the outer panels. If its leaking, replace the valve. Dazza

Tip

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.

My Titanium leaking water. Under it


The steam valve assembly that the steam knob on the right hand side connects into is probably faulty. When you're steaming if you hear hissing coming from behind the knob then this indicates the connections into this assembly are leaking steam, and also hot water, which is why you're getting puddles under the machine. You can get a replacement steam valve assembly that fixes some issues with the original (part code SVM-17, available from www.partsguru.com) and will prevent the leakage, or you could simply try opening the top of the coffee machine and removing the tube that runs from the boiler into the steam valve. It has two o-rings that provide the seal where it connects into the steam valve assembly, and if you lubricate these with a food grade silicon lubricant it may fix the problem. My Gaggia is 7 years old so I decided to replace the whole assembly which costs about $50 and that solved the problem completely.

Steam valve is starting to leak when closed. Does the valve use O-rings that can be replaced?


Yes it does, but it might be easier to replace the complete valve, than the pins and the o-rings.

Saeco incanto rapid steam leaking from under


The leak is most likely from the steam valve, you will have to either buy and replace the o-rings and the pistons in the valve or just buy a new valve assembly and replace it. Easiest solution get the new valve assembly.

Steam Wand Leaking on La Pavoni Espresso Si


I HAD the same problem. I fixed it for 50 cents. It takes the removal of 4 screws (2 phillips on top, 2 long standard on bottom by the group) to remove the top to access the steam wand valve. Once the the top (and the chrome bezel) is removed, then screw out the valve counterclockwise buy ALL THE WAY until it comes out. There are 2 O-rings on the stem of the valve that wear out, Cut these off with a sharp knife, go to your local hardware store, buy 2 new ones for 50 cents, install new O-rings, and reverse the disassembly procedure. Voila, no more leaky steam valve!
