There Is Dirty Water Under My Machine.

Water under your machine, most of the times, means there is just a leak somewhere and you need to find it.

Dirty water under your machine means something else.

Espresso machines have drain hoses or some sort of outlet for drainage.

If you are finding dirty water under or around your machine, it is likely that your drain hose or outlet is being blocked somehow.

Check the end of the drain hose to make sure it is not crammed up into the drain destination, or if you have the hose in a bucket, ensure that the end of the hose is not in the water.

Also, make sure the hose is not kinked anywhere, or that nothing is sitting on the hose, stopping the drainage flow.
