Water leaks out of the bottom of Saeco Vienna. Removed the top and appears to be leaking out of the boiler (warm thing on the left). What can I do?

if the water is clean -it could be the boiler,if is not exactly clear water -just clean under brew unit motor-when take off brew unit.There can be durty coffee

Could be a leak in the high pressure lines or the boiler. The boiler leaking was a issue on the order models by saeco.

Here is a link the boiler that is most likely in your machine. 2 element boiler

The o-rings of the water tube coming out of the boiler need to be changed. Rubber O-ring tend to expand after extended exposure to heat.

1-Try changing the seal of the water inlet under the tank (part# NM05.006)

2- Check the o-rings from the water tubes coming in and out of the boiler.

Is it leaking only when brewing coffee ?

If not I would check the seal under the water tank (Part #NM05.006)

If so, I would check the following:

1- The water input port on the back of the brew unit (looks like a smoke pipe) might be clogged

2- The o-ring of the water tubes coming in and out of the boiler.

It is possible that the o-rings in the hose fittings are worn out and need to be replaced.

Hi,

If you take off the top and start your machine you will see and hear if the boiler leak, try this first to work around your problem.

Let me know if i can help you more.

Hi,

It can be the steam valve or the boiler that is leaking.

Hi,

There are two things you can do.

1. Get a gasket with spare part number 9011.129
2. Get a new boiler spare part number 286473055 (120V), 286472858 (230V)

Depending on the age it could be just some orings leaking or a connection that has come loose. Or it could be the boiler leaking. Not knowing the age it is had to know which. You should google "saeco repair" and have an authorized repair center take a look.
