Bambino Plus BES500 Cleaning Cycle Problem

Bought my Breville Bambino Plus (BES500) August 2019, all working fine, till now. Recently, every time I turn ON the machine, the 1 cup and 2 cup light flashing alternately. Based on the user manual, it's time to perform the cleaning cycle (back flush).

According to the user manual, I need to press and hold the 1 cup + 2 cup button, for 5 seconds, to enter the cleaning cycle mode. However, the same button sequence, is to program the 1/2 cup volume. I can't seems to enter the cleaning cycle mode.

Anyone has a Bambino Plus done a cleaning cycle before?



    Press and hold the 1 CUP and 2 CUP buttons for 5 seconds to enter the cleaning cycle mode.

    Programming volume is 2 seconds. Obviously the machine knows which is which

    • The problem is it's not so obvious. I tried following the user manual and it didnt work. I googled the problem and a few people actually having difficulty entering cleaning cycle as well.

      Just trying my luck here to see anyone here done it before.

      • It's definitely not flashing the steam light as well, indicating a descale, not clean, is needed?

        • No, definitely 1-cup and 2-cup lights flashing alternately

        • They had a video showing how to perform cleaning cycle, and they removed it because people are complaining it's misleading.

      • Having the same issue. Both 1 and 2 Cup buttons are flashing alternately (all the steam related lights are off).

        Did the Cleaning Cycle as per manual by pressing and holding the 1 and 2 Cup buttons (at the same time). Both buttons flashed then remained steady (lit). Pressed 1 cup button and the machine did something. Unlike the video shared you shared though, none of the water flowed down the group head. To me this makes sense coz the cleaning disc is blocking the water from flowing through. Anyway, the cleaning cycle ended, and not a single drop of water flowed out of the group head or the steam wand. Makes me wonder the need for putting in a 2L container under the group head/steam wand as per manual.

        After restarting the machine, both buttons still flash. I did a descale and got the same result still.

        I tried to redo the Cleaning Cycle but the machine no longer allows me to.

        So long story short, the 2 buttons still flash until now. Did you get yours resolved?

        • Yes, it took me quite a while to sort that out.

          1. The machine can only enter cleaning cycle, when the 1 and 2 cup buttons are flashing alternatively. That is, when you see the 1/2 cups button flashing alternatively, press both button for 5s, till they remain solid.
          2. Start the cleaning cycle by pressing either 1 or 2 cups button. The cleaning cycle is going to take about 5 minutes, and it has long pause in between backflush, doing nothing, making you think the cleaning cycle is completed. When the cleaning cycle is completed, the machine will go into ready mode (cups button and steam wand buttons all light up, and so are the temperature and froth level lights).

          Yes, you don't need that 2L jug, no water will come out from the portafilter. But make sure you drain the drip tray before you start the cleaning cycle, it might get overflow due to multiple backflush.

          Good luck

  • Hi I am still not able to get it to stop flashing after it drops out a bit of water it just starts up with both lights flashing.

    • what's the blinking pattern when you power on the machine ?
