Question about Cuisinart EM-100CP Espresso Maker Cleaning Pins

1 Answer

Espresso machine sprays espresso

Brand new machine for Christmas. It constantly sprayed espresso out the back of the brew head, so I returned it and got another. Same thing. I've tried different grinds from course to fine, different tamp pressures, different levels of espresso in the filter with the same results (always fresh Starbucks espresso beans). One thing I did notice is that sometimes it drips okay if I brew the espresso before frothing milk, but if I froth milk first and then brew espresso, it always sprays out back. But this only helps sometimes, and that is backwards anyways, as the espresso has cooled down when it has to wait for the milk to froth. I noticed the filter only has one small hole for the drip. My older Starbucks Barista filter has many holes in the filter and I never had this problem. Any ideas that I can try before I take this one back as well and spend more money on a different brand?

SOURCE: Half of the time, espresso leaks (or sprays) out . . .

It sounds to me that your group seal is bad. Since this machine is a 15-Bar unit, it puts out quite a bit of pressure causing water to leak out around the portafilter when making espresso if your seal is old or damaged. The pressure doesn't build up as much when you are running just water through the machine - hence the reason why the machine works ok without grounds. I sell a LOT of parts and accessories for various manufacturers of espresso machines. This particular seal is extremely difficult to locate fom Cuisinart, but is rather easy to replace. Through extensive testing, I have located a replacement gasket produced by another major manufacturer that fits the Cuisinart EM-100 & EM-200 machines perfectly. I sell them for $10.99 each (or two for $19.99) which includes shipping in the continental US and I accept Paypal. If you would like to contact me via email (, I will be happy to help you out.

Bunn cwtf20-3 makes weak coffee

When you pull the basket out after its finished brewing what does the surface of the coffee look like? Are there 6 or so clearly defined dimples in the surface where the water pours from the spray head? Is the powder uniformly wet? If the answer is no to either of these, remove and clean the spray head. Use a descaling tablet or powder to soak the spray head and then use a small tool to clear the holes. Be careful not to make the holes bigger though.

Weak Coffee

First think to check is the spray head which pours the water onto the powder. remove the spray head, clean it and soak it in descaler.
reassemble and do a brew. When finished check the surface of the coffee has 6 dimples where the water has poured onto it and that the coffee is uniformly wet. If no dimples or dry spots, get replacement spray heads.

Will not brew

Make sure the coffee maker is full of water. Keep filling it till water comes out of spray head.. Should take two full pots plus 3/4 of another one. Wait for water to stop coming out of spray head. Now the unit should be ready to brew after it heats up.

Is there a way to stop coffee from spraying?

There is a little part that sells on ebay for $2 that slides into the Keurig brewer lid and stops coffee from spraying from reusable K-cups. It works great and is guaranteed or money back. Here is the link:

Coffee stopped coming out of nozzle

The problem with your machine is the connection where the brew unit connects to the dispensing head is broken. This is why the machine is leaking into the dump box. I wish it was an easy fix, but it is not.

You will have to get the machine serviced.
