Does the pump work? The steam and hot water are from the boiler pressure, but the coffee water circuit is separate and needs the pump.
Does the three way solenoid valve click when you try for coffee?
Why did you change the control box, what was the original fault?

    We have put an external supply to the solanoid and pump, both work but there is no voltage at thepump or solanoid coming from the machine. We changed the control box as i was advised to by an engineer.

SOURCE: Machine Does not draw water into the boiler

I have had this same problem - it is due to an airlock in the boiler/tubes. Simple solution is to use a syringe or similar and gently force some water up the intake hose from the tank, then try the pump again.

SOURCE: ventilate warning came on and machine no longer works.

Hi The first thing that I would check is the tip of the steam wand for a plug. If that is clear then I would suspect a clogged flow meter. If you can get the flow meter out it twists apart and don't loose the parts and the dot on the turbine goes up. Clean out the small opening on the bottom pipes where the hoses attach. Look inside and make sure that they are clear before reassembling.

SOURCE: My steam/hot water arm fell out along with no steam

Easiest way to get to it, remove the 2 screws in the bean hopper, and remove the hopper, there are a few screws under the water tank, this should give you access to the machine top. Check the end of the steam wand it might be blocked use a paper clip to clear it out. Run it under the faucet to make suree it is clear. Check the microswitch that is connected to the steam valve, It can be seen when you turn the knob to open the steam/hot water valve, make sure it is not stuck in the on position.

SOURCE: Saeco Odea Go - Hot water leaks from bottom of machine

That's leaking from the hoses coming out from the boiler,if the machine is new it should be still under warranty, may have to take it back to the service center.When making coffee the lines are under pressure and the water never have a chance to pass through the ground coffee.

SOURCE: I have a gaggia platinum vogue that wont brew

Hi,

Some times The steam knob may be slightly open. Twist the steam wand knob towards you, firmly, to a fully closed position.Check Pressure releif valve, the fill water inlet is on.Block in solenoid valve.
if still persist the pressure gauge should be replaced.I had a case where the Espresso had pressure built in and it may blow out.So please call the service man for your safety.

Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thank you for using fixya have a nice day:-)

Your front brew boiler likely has a dead heating element or there is a problem with the electrical system for the front boiler.

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.

No steam just hot water but pump is working.


Either the thermostats on the steam booster boiler, has tripped, or the element on the steam boiler is damaged, or the CPU board is not sending power to steam boiler. Use an Ohms meter to check the thermostats and the element on the steam boiler.

Franke saphira will not exit rinse unit, will not rinse the coffee head but will supply hot water and steam. but will not depense any coffee. help please. I have had a Franke Man out and he has no clue he...


The machine has two pumps - one for each boiler. Did the Franke man check both pumps were working. If the main boiler pump has failed, the machine will know that the rinse hasn't occurred and won't go any further.

Steam wand sprays hot water and very little steam. Cannot get a good frothed milk. Machine is also leaning forward by about 5degrees. Is this normal?


The boiler lever sensor is dirty, full of scale or bent so more water getting in the boiler than it should be. Try to remove the lever sensor clean it with a brush and put it back.

Water wont flow past brew head


Hi there, it sounds like your boiler may be full of scale. There is a copper tube which runs from the group up inside the boiler which can get clogged up quite easily. When you take the group apart you will see that when you remove the shower plate and unscrew the bolt in the middle the safety valve and spring will pop out and then if you get a pipe cleaner or something similar and ram it up through the copper pipe. If this does not work then you may have to dimantle the boiler and give it a good clean out. Also although you say the pump is primed it could still be broken. All these problems usually come from scale though. If you get some descaler and try to feed into the boiler by pumping or running water out the steam wand this may free it up.

Grimac ZOLA II - NO HOT WATER !!!


The problem is either the switch that controls the solenoid for the hot water valve, or the solenoid itself. Place finger on the solenoid coil and press switch if the solenoid is working you will feel the nucleus when it engages. If both switch and solenoid are working then the pipe connected to the solenoid from the boiler is clogged.

Saeco via venezia overheat cut out


Disconnect from the power and remove the 5 or 6 grub screws retaining the main steel cover and take the cover off. You will see a plastic re-set button on top of the boiler amongst the electrical terminals - just click it on again.

To stop overheating always open the steam valve immediately you switch the machine on until water squirts out - this tells you the boiler is full & not dry! Also remember (unlike me!) to switch the machine off as soon as you have finished brewing...

No hot water or steam


Well, I have little exposure to Saeco, but a lot to commercial coffee machines.
Saeco have a lot of custom made components, although these can be purchased, nothing is cheap! Neither is their repair service!
First, is the boiler heating?? If so:
No hot water/ no steam suggests a blockage. Assuming you can hear the pump working when attempting to do a coffee, you will probably find the water flowing back into the water tank via the relief valve. Of course, this valve itself could be the problem, or the pump failing to work through a blocked inlet filter or other problem.
Look now at the group head. Ever cleaned it? The filter and spray block should be removable, do so and clean them carefully. While you have them out, see whether water reaches the head by "making a coffee" into a cup placed under the head. BE CAREFUL OF SCALDING. If water now flows, cleaning the screen and spray block should restore operation.
Beyond that, it's inside the machine! There is a 3- way valve that operates when making a coffee. This can become clogged with coffee. There is another valve to open the steam.
If, like Saecos I have worked on, the boiler does both the hot water and the steam one at a time, look for problems BEFORE the boiler.
Hoe this helps a little....
