My Mom uses a Spidem trevi Digital machine. While brewing, there was too much coffee grounds in the brew unit and it couldn't compress the grounds, so it was stuck and wouldn't return to the home position. (too oily of beans caused this) I had to disassemble the gears on the back to remove the brew unit. After everything was put back together, i was able to brew a few cups of coffee, then shut the machine off. The next morning, the ventilate / fill water tank error was on the machine.
I've done the following to try to remove this error:
Descaling the machine.
CHecked for loose connections, electrical and plumbing. I even cleaned out the hoses which were filled with gunk,.
Ensured connectors are in the right place.
After the major overhaul, The steam wand dispenses hot water just fine.
Am I missing something simple or is this a possible PCB malfunction?
Thanks,
Neil

Hi and welcome. I apologize for the delayed reply.
So are you saying the pump works as normal, but the screen displays the error still?

Thanks for your response! The pump does work as normal. I initially was able to get a few shots to brew, but then it came up with this error. I can purge water through the frothing wand.

That is odd. Normally when the ventilate message pops up, it means that there is air in the circuit, but as soon as you prime the pump by dispensing water through the steam wand, the message goes away.
Is it possible you have the wires reversed on the pump?

It's possible. I'll double check. How does the machine know that there is air in the line? For all other errors, there's micro switches or hall effect sensors, but i'm stumped on this one.

| There should be a sensor or 2 electrodes before or part of the pump resulting in 1 or 2 additional wires (the other 2 being hot and neutral). This sensor tests conductivity. If you are using Reverse Osmosis or Distilled or De-Ionized water, this can interfere with the sensor.

The wires to the pump are correct; they match the designations on the pump. The only sensor I see on the pump is the overtemp sensor. I cannot find any sensor that measures continuity in the water circuit. Can I get a picture of the back of the PCB to make sure the sensors are all plugged into the right connectors?
Ventilate and Fill watertank are the errors on the screen. Thanks, Neil

| Try to clean "Flowmeter" again and waiting machine cold down about 15 min then turn machine on.

Flow meter is clean and works. I would like to find a part diagram of the back of the PCB's so I know that everything is hooked up correctly. Or if somebody can tell me where the ventilate sensor is located. Thanks, Neil

| I was recently speaking with Kim at Saeco customer service on an unrelated matter and brought up your dilemma. I indicated you were outside of your warranty, but Saeco still recommended you get in touch with them at http://www.saecooutlet.com. They have live chat on the left hand side, but they are not always online, as well as email contacts. She said they can't guarantee they'd be able to solve your issue but might be able to point you in the right direction.

While waiting for Saeco to contact me, I've done some more troubleshooting and tracing of sensors. I've found all of the sensors that feed into the PCB and know their purpose except for 1. This is a transistor that embedded into a plastic housing (see picture). This mounts on the top of the boiler and has conductive paste from it to the boiler housing. Is this possibly the sensor that's sensing continuity in the water? I have noticed when I purge water out the steam wand that it's very steaming water, maybe the steamer is only working and not the boiler?

I did contact Saeco and unfortunately all they told me was to go to the nearest parts center. I suppose I'll have to learn Italian so I can actually read the manuals.

Hello, if this theme still actually, i can help it. But if the trouble is done, let's my note help to the people who have the same problem and found this thread.
Sorry because of my English - i live in Russia.
So, we have "fill watertank ventilate" message. We must to clean the system BEFORE the pump (we decide the pump 100% guaranteed working, of course). I think, the trash collected to the input hole of the flow sensor - it happens so frequently. (Flow sensor is a wired device between the watertank and the pump). We must disconnect the both silicon pipes from the sensor, gently disassembly it, and clean the input hole with a toothpick.
That's all. I hope, i help.
Maybe, somebody who understood my text, repost it there with correct English language, for anybody and for me too.
Thank you.
