During the brew,the machine suddenly stopped brew, and machine’s 4 buttons light began to flash, what is the reason?

It should be that the machine is short of water, you can check whether there is still water in the water tank. You can refer to the below video. (youtube.com/watch?v=7jFy_YcBu4k)

Why is there a lot of steam coming out of the machine when I'm about to make coffee after frothing milk?

Because after the machine uses the steam function, the temperature inside the machine is very high. If you need to make coffee at this time, the machine will release the pressure and a lot of steam will come out.

I have a question about the portafilter holding water after espresso has brewed, what's wrong?

Hi,reasons why water remains on the filter after making coffee:

1. The coffee powder is too fine

2. The coffee powder is pressed too tightly

3. Too little coffee powder

4. The small holes of the filter are blocked, and need to be cleaned.

I have used my machine for almost a year and recently I noticed that it is producing less water, how can I fix it ?

Maybe the portafilter filter is blocked, please try the following:

1. Use a brush to brush the small holes of the filter and the middle hole at the bottom.

2. Soak the filter with descaling agent for about a day.

3. Clean the filter

It seems a bit complicated to operate, do you have any instructions to make it easier for me to use?

We have prepared a lot of operation instruction videos for you, such as the video is about How To Make Perfect Espresso Coffee with Gevi GECME418E-U Espresso Machine, you can find on product page.
