My machine is leaking
If you find that your ECM Casa V is leaking, be it from the portafilter, steam wand, the boiler, or from the bottom of the machine, review the following to troubleshoot the issue.
Is coffee coming up and over the portafilter?
- Replace the group gasket.
Is it steaming from above the machine through the vents on top?
- If there is steaming coming out of the top of the machine, the top of the machine should be removed to determine where the leak is coming from. This will likely be a result of a loose or damaged fitting.
Is the leak coming from around the nut where the steam or hot water wand attaches?
- There is an o-ring in there. You can try to tighten the nut first. If that doesn’t stop the leak, take it off, and check on the o-ring that sits in there. The o-ring should be placed at the bottom of the nut resting in a channel on the inside of the nut. This will either be a rubber o-ring or teflon ring. It may either be worn or damaged and will require replacement.
Is it dripping or leaking out of the tip of the steam wand?
- Yes. It should leak or drip a little bit after use, and when the machine is first started up. This is normal, and due to condensation in the pipe. It should subside after a few minutes of non use.
- Yes. The valve has a shaft that runs through it and on the end of this shaft is a teflon tap. If there is debris present in the valve, it will cause this teflon tap to not properly seat and will let water past it. The teflon tap may also be worn out from age or being over-tightened and no longer is able to properly seal, allowing water to get past it.
Is the leak coming from between the steam tip and the wand?
- There is a rubber o-ring or teflon gasket in between them that may need to be replaced.
Is the leak coming from the boiler itself?
- Is it leaking from where a valve screws into the boiler?
- Remove the valve, and clean any remnants of sealant. You can use teflon tape, Permabond, or Loctite to reseal the valve back into the boiler.
- If the brew boiler sits on top of and attaches to the group head, there is a gasket that sits between them. If water is present coming from this location between the boiler and the group then either the bolts need to be tightened, or the gasket is bad and requires replacement.
I cannot find the source of the leak.
- Run the machine to allow it to heat. Some leaks may only be apparent under heat and pressure.
- You can open the machine and send us any photos or videos, so we can determine if we can find the source of the leak.
- Send the machine in for service.
Is the leak coming from the bottom of the machine?
- Inspect the plastic reservoir valve socket. If it is cracked, it will need to be replaced.
