Best cleaning solution or powder for Color?
« on: April 17, 2017, 05:09:00 PM »
Used Cleancaf in my Color and now it does not work, except for the steam wand.  In 6 years, I'd used only descaler.  What happens is the temp and pressure build up, then the machine cycles down to nothing once I try to brew.  Any suggestions on the next step?

Thanks.

Eustachio, welcome to GUG.

Cleancaf information is here

http://urnex.com/household/product/cleancaf-coffee-machine-cleaning-powder/

It is a cleaning agent for coffee equipment, not espresso, as you can see from the site. It is not really effective as a descaler.  Hopefully, you can run a descale agent and be back in business.  If you have the steam valve open and turn on brew, does water still flow through the wand?  The group valve is 21 - 32 here

and may be stuck with scale.  Try the descale and if not a cure, search group valve and there is more specific information on cleaning and removal.

Many thanks, for your welcome and reply.  Both the package and the Amazon site claim it is for espresso machines, but to answer your question, yes, the wand will let water through, or did, for the most part.  Is that a good sign?

Again,
many thanks!

I know that there are suggestions of use for espresso machines, that was not my take from the Urnex site sent.  In addition, there doesn't seem to be the acid needed for real descale if you look at MSDS, or SDS shown via the Urnex site. I understand why you used it and I have also seen those advertisements.

Water from the wand suggests that the pump is ok as expected, and that the blockage is the group valve also as expected.

Try real descale with a descale (only) product.  Usually the main ingredient is an acid or two.  Sounds like you have used those before.  If not successful, then you can search the group valve and "mechanical" solutions.

Just to add to D4F's comments - referring to the parts diagram, link above, a quick check is to remove the shower screen screw (#37) then use a coin or similar to undo the group head valve screw (#23) - inside you'll find a spring (#22) and a rubber end (#21) - when the pump runs the pressure is designed to push the rubber end down and hence water flows to the shower screen/puck etc - check to make sure the rubber end and spring move - sounds like you've got some kind of blockage that's stopping this, most probably scale. This is why no water is coming out of the group but does come out of the wand.

Many thanks to you both!

Descaler arrives tomorrow.  But will try disassembling the head, too, which I've never done in 6 years.

Great to have found this site.

Once again, many thanks!

Cleaned with descaler (liquid), cleaned brew screen.  First cup worked.  Will follow up before long.
