Common Questions

FAQs

  1. What should I do before using my Marenza for the first time?
    Wash and dry the removable accessories, fill and securely install the water tank, then install the bean hopper. Turn the hopper knob clockwise to open the bean channel. When “Flushing” appears, place cups under the brew head and steam wand, insert an empty filter basket, and press Flush. The first-use cycle takes about 90 seconds. Wait until the machine finishes preheating before brewing.

  2. How do I install the bean hopper?
    Align the hopper with the markings on top of the machine, lower it into place, and turn it clockwise until secure. Then turn the hopper knob clockwise to open the bean channel. If “Install Hopper” appears on the display, remove the hopper and reinstall it, checking that it is fully locked in place.

  3. Which filter basket should I use?
    Start with a single-wall basket when grinding fresh whole beans and you want to adjust the grind and dose yourself. A dual-wall basket is a more forgiving choice for pre-ground coffee or when you are still dialing in your espresso. Choose the one-cup or two-cup size to match your intended shot. The blind basket is for backflushing only—do not use it to brew coffee.

  4. What grind setting and coffee dose should I start with?
    Start at grind setting 10, then adjust based on the flow and displayed brewing pressure. The manual suggests approximately 13 g for a single espresso or 19 g for a double. These are starting points: bean freshness and roast can change the grind and dose you need. Avoid starting at settings 1–3, which may be too fine.

  5. Can I customize a drink’s volume?
    Yes. Press Volume, turn the brew dial to select the drink, then press the dial to start brewing. Press it again when the cup reaches your preferred volume; the machine will save that setting. To restore the default grind times, temperatures, and drink volumes, press and hold Volume for five seconds.

Common Troubleshooting Questions

  1. Why does the display show 0 bar or low pressure, and why is my espresso thin or lacking crema?
    Check the coffee and extraction first. Use fresh beans, make sure the hopper’s bean channel is open, and check that enough coffee is reaching the basket. If the shot runs quickly, move to a finer grind in small steps and try again. The manual’s suggested brewing range is 6–12 bar. If pressure remains at 0 bar after changing the grind and dose—or the machine cannot build pressure even with a dual-wall basket—contact CASABREWS Support with a short brewing video.

  2. Why does espresso drip very slowly or not come out, or why is pressure above 12 bar?
    The grind may be too fine or the basket may contain too much coffee. Try a coarser setting and reduce the dose slightly. Check that the basket and brew head are clean. If water also flows slowly without coffee, follow the manual’s cleaning and descaling instructions.

  3. Why is the grinder not dispensing coffee?
    Check that the hopper contains beans, is fully installed, and has its bean channel open. If the grinder runs but little or no coffee comes out, switch off and unplug the machine before checking the grinder chamber and chute for a blockage. Clean the burrs and chute with a dry brush; do not wash the burrs with water.

  4. What should I do if E4 appears on the display?
    Stop the current operation, unplug the machine, and plug it back in, as directed in the manual. If E4 returns—especially during the first-use flush or a cleaning cycle—do not repeatedly restart the cycle. Contact CASABREWS Support and include a photo of the display and a brief video showing when the error appears.

  5. Why is no water coming from the brew head?
    Make sure the water tank contains water and is pushed fully into place. Remove the portafilter and check whether water flows from the brew head without coffee. If flow is still absent or weak, check for a blocked filter or follow the descaling instructions. Contact Support if the problem persists.

  6. What should I do if water leaks from underneath the machine?
    Stop using the machine and switch it off. Check that the water tank is fully seated and inspect the tank and drip tray for visible damage or overflow. If water continues to leak from the machine body, do not keep operating it. Contact CASABREWS Support with a photo or video of where the water appears.
