Resevoir leaking on Saeco Trevi(like Vienna)

If your Saeco Vienna Deluxe espresso machine is experiencing leaks from above the door panel during coffee brewing, even after cleaning and descaling, there could be a few potential causes for this issue. Here are some steps you can take to troubleshoot and address the problem:

1. Check Brew Group Seals: The brew group is a critical part of the espresso machine. If the seals or gaskets on the brew group are worn or damaged, they could allow water to leak out during brewing. Inspect the brew group and its components for any visible signs of wear or damage. If necessary, replace the seals or gaskets.
2. Check Door Seal: The door seal or gasket that creates a seal between the door and the machine's interior could be compromised. Inspect the door seal for any visible defects, cracks, or damage. If the seal is not making proper contact, it could lead to leaks. Replace the door seal if needed.
3. Overflowing Drip Tray: Ensure that the drip tray and the drip tray float are functioning properly. If the drip tray is full or the float is stuck, it could lead to water overflowing from above the door panel. Empty the drip tray and ensure that the float moves freely.
4. Brew Unit Alignment: Make sure the brew unit is properly aligned and inserted into the machine. If it's not properly seated, it can cause water to leak during brewing. Remove the brew unit and reinsert it, ensuring that it clicks into place securely.
5. Clogged Drainage Channels: Check for any clogs or blockages in the drainage channels or tubes inside the machine. If water is not properly draining, it can result in leaks. Clean out any debris or buildup that you find.
6. Water Tank Seating: Ensure that the water tank is properly seated and securely in place. If it's not properly positioned, it can lead to water leaks.
7. Internal Hoses and Connections: Inspect the internal hoses and connections for any signs of leaks or loose connections. Tighten any fittings if necessary.
8. Professional Service: If the issue persists after checking and addressing the above potential causes, it may be best to seek the assistance of a professional technician or service center that specializes in Saeco espresso machines. They can diagnose and repair more complex issues that might be causing the leaks.

Depending on your ability to do some technical and minutious manual work, unmounting and remounting the machine is feasable.

Concerning the leaking, what I've seen most is a leak from the seal under the water tank. Any leaks coming form there would occur even though no coffee would be dispensed. (i.e: Idle mode)

If leak is ONLY occurring when brewing cofee, I would check the following:

1- Check if the water inlet on the back of the brew unit is filled with residue (the inlet looks like the end of a smoke pipe)

2-Open the machine, take out the interior, and verify the water tubes coming in and out of the boiler. They both should be sealed with 2 small o-rings. After time, o-ring tend to expand under heat and may start to leak.

Hope this helps

you could have a blown head gasket and coolant could be leaking into your combustion chamber.
rent a radiator pressure tester and see if the cooling system will stay at constant pressure. If the pressure drops you have a leak, and it could be your gaskets. pretty costly to repair.
make sure you have not blown the seals on the engines water pump. when they go out, the burst disc on the pump open and gush coolant everywhere.

Your head gasket has blown or the cylinder head has crancked.You are getting compression in the water system thats why you are getting spill out from resevoir tank.

What can have happened is that through an overflow of used coffee the hole in the back is stuffed with the ground used coffee. The way to solve this is getting out the brewing group and rinse the hole with water after removing the cloggin coffee residu. You can find this hole just beneath the outgoing axle.

I have had the same problem with my Saeco Digital & Saeco Superautomica machines. After much work and somewhat expense I have finally found a simple fix. All you need to do is replace the gasket which is located just under the water reservoir.
(1) Take the water reservoir off
(2) Pop the round plastic piece located in the middle off (don't worry you won't break it as is it pretty tough)
(3) Take the black rubber gasket out and either:
(a) cover the present gasket with the brew group lube or
(b) replace the gasket with a new one.
which will give it a air tight fit and prevent any further water leakage from the reservoir.

You can get a new gasket for $5!!! :) I got mine at: http://cerinicoffee.com/item.asp?cID=0&PID=90

I also put some Brew Group lube ( http://cerinicoffee.com/Lube_brew_group_saeco.asp ) around the gasket as a temp fix until I completely replaced to gasket. Apparently, what happens is that the original gasket gets old, dry rots or whatever allowing the water to leak out of the reservoir. And then all over your work surface. The Saeco machines are quite intricate but are
Hope this helps.

Hi,

There are no screw to be removed, you have to take off the plastic ring in the water inlet. Take a screw driver and set it between the chassis and the water inlet.

Hope this will help you.

Hi,

Where are you from?

We had this problem and it was overflow from a clog -- check the hole where excess water drains into the drip tray to see if it is full of grounds. Cleaned it out with a twistie tie and flushed w/ water. That stopped the water on our counter!
