Why is the coffee flow weak in my Bezzera Coffee Maker?
- J
  Jason MendozaAug 19, 2025
  If the coffee flow from your Bezzera Coffee Maker is weak, it could be due to several reasons. The coffee might be ground too finely, or it's overly compressed in the filter holder, or the dose is too high. Also, the group shower or the filter in the filter holder might be blocked, or the pump pressure is too low (less than 9 bar). Adjust the grinding and dosage to fix the first three issues. For blocked components or pump issues, it's best to get a technician to take a look. Clean or replace the filter if it's blocked.

Why is my Bezzera Coffee Maker dispensing cold coffee?

  If the coffee from your Bezzera Coffee Maker is too cold, it might be because the cups or filter holders are cold. It could also be due to the coffee being ground too finely, scale buildup in the machine's water circuit, low boiler pressure (below 0.8 bar), or a cold group. To address this: use a cup warmer, keep the filter holder attached to the group to keep it warm, and adjust the coffee grind. For scale buildup, low boiler pressure, or a cold group, consult a technician.

Why is the coffee flowing too fast from my Bezzera Coffee Maker?

  Charles BondAug 23, 2025
  If the coffee flow from your Bezzera Coffee Maker is too abundant, it could be due to a few reasons: the coffee might be ground too coarsely, it's not pressed enough in the filter holder, the coffee dose is too low, or the pump pressure is too high (over 10 bar). Adjust the coffee grinding and dosage to fix the first three issues. If the pump pressure is too high, you'll need a technician to resolve it.

What to do if having difficulty positioning the filter holder on my Bezzera OTTO Coffee Maker?
- J
  Jared CherryAug 26, 2025
  If you're finding it hard to position the filter holder on the Bezzera Coffee Maker's attachment ring, it's likely because there's too much coffee in the filter holder. Try reducing the amount of coffee you're using.

What to do if my Bezzera Coffee Maker is not dispensing coffee?

  If the coffee isn't dispensing from your Bezzera Coffee Maker and the button for the selected dose is flashing, try selecting the coffee dispensing button without the filter holder to see if the water flow is continuous. If it is, the problem is either that the coffee is ground too finely or the filter holder is blocked. In this case, soak the filter holder in hot water with suitable cleaning tablets. If the water flow isn't continuous, contact a technician.

Why is my Bezzera Coffee Maker dispensing coffee that is too hot?
- A
  Annette SalazarAug 30, 2025
  If the coffee from your Bezzera Coffee Maker is too hot, it could be due to a few reasons: the boiler pressure is too high (above 1.3 bar), something is covering the machine and preventing it from cooling, or the machine is installed in a location that doesn't allow for air circulation. In the first case, call a technician. For the other cases, make sure the machine can cool down properly.

Why is there coffee deposit at the bottom of my cup from Bezzera OTTO Coffee Maker?
- D
  Dr. Jennifer Maldonado DVMSep 1, 2025
  If you notice coffee grounds at the bottom of your cup when using your Bezzera Coffee Maker, it could be due to several reasons: the coffee is ground too finely, the filter holder is dirty inside or the filter is damaged, the grinder burrs are worn, or the pump pressure is too high (over 10 bar). Adjust the grinder for coarser coffee to fix the first issue. Clean the filter holder or replace the filter to address the second. For worn grinder burrs or high pump pressure, it's best to consult a technician.

  If the filter holder on your Bezzera Coffee Maker doesn't sit correctly once attached to the group, it's likely that the group gasket is worn. It's best to call a technician to replace it.

How to fix no steam coming from the Bezzera Coffee Maker steam tube?
- B
  Brian HallSep 6, 2025
  If the steam isn't coming out of the steam tube on your Bezzera Coffee Maker, it's probably because the nozzle of the steam tube is blocked. Try clearing it with a pin. Remember to clean the steam nozzle after each use.

Why is my Bezzera OTTO dispensing lukewarm coffee?
- M
  Mary MannSep 8, 2025
  If the coffee from your Bezzera Coffee Maker is lukewarm, it might be due to a false pressure reading. Call a technician to check the vent valve. In the meantime, to use the machine, open the steam tap to bring the boiler pressure down to zero, which will activate the heating element and increase the temperature. Do this every day when you turn on the machine.
