  If the coffee from your Bosch Coffee Maker tastes burnt, it could be due to several reasons. The brewing temperature might be too high; reduce the temperature. The coffee might be ground too finely, or the preground coffee is too fine; adjust the grinding level to a coarser setting or use a coarser ground coffee. Also, the type of coffee might be unsuitable, so try changing the type of coffee.

  If your Bosch Coffee Maker produces coffee that is too “bitter”, it could be because the coffee is ground too finely, or the preground coffee is too fine. Adjust the grinding level to a coarser setting or use a coarser ground coffee. It could also be due to an unsuitable type of coffee, so try changing the type of coffee.

Why is there too little milk froth from my Bosch CTL836E 6?
- E
  Emily HenryAug 30, 2025
  There could be several reasons why your Bosch Coffee Maker is producing too little or no milk froth, or why the milk system isn't taking in any milk. It could be due to a build-up of limescale in the appliance, so descale the appliance according to the instructions. The beverage outlet or one of the three connections could be blocked, so clean the beverage outlet and the connections. The milk itself might not be suitable for foaming, so avoid using milk that has already been boiled and use cold milk with a fat content of at least 1.5%. Also, the beverage outlet or the milk tubes might not be correctly assembled, so moisten the individual parts and put them together again. Finally, the suction pipe could be blocked, so clean the suction pipe.

Why is my Bosch Coffee Maker display showing “Milk container connected?” despite connected milk container?
- B
  Brian GuerreroAug 29, 2025
  If your Bosch Coffee Maker display shows “Milk container connected?” despite the milk container being connected, it could be because the container is outside the range of the sensor. Try positioning the container at the right edge. It could also be that the material, for example, a milk carton, is not recognized. In this case, confirm the display request with “Yes” or use the enclosed milk container.

What to do if my Bosch CTL836E 6 Coffee Maker display shows “Fill bean container” although the container is already full?
- B
  Brian AustinAug 27, 2025
  If your Bosch Coffee Maker display shows “Fill bean container” although the container is already full, or the grinder is not grinding any beans, it could be that the beans are not falling into the grinding unit because they are too oily. Try gently tapping the bean container and possibly change the type of coffee. When the bean container is empty, wipe it with a dry cloth.

Why is my Bosch CTL836E 6 display showing “Refill with still water or remove filter”?
- M
  Melvin OrtizAug 27, 2025
  The Bosch Coffee Maker might display "Refill with still water or remove filter" due to several reasons: the water tank might be wrongly inserted, so ensure it is correctly inserted. It could also be due to carbonated water in the water tank, so fill the water tank with fresh tap water. Another reason could be that the float is stuck in the water tank, so remove the tank and clean thoroughly. It may also be because a new water filter was not rinsed according to instructions, or the water filter is used or defective, so rinse the water filter according to the instructions and then switch it on, or use a new water filter. Finally, there might be air in the water filter; dip the water filter into water until no more air bubbles escape, then replace the filter.

Why is my Bosch Coffee Maker display showing “Empty drip trays” even though they are empty?
- P
  Patrick HarrisAug 26, 2025
  The display might show “Empty drip trays” on your Bosch Coffee Maker even if they are empty because the drip tray is soiled and wet. Clean and dry the drip tray thoroughly. Alternatively, the emptying might not be detected when the appliance is switched off. In this case, remove and re-insert the drip tray when the appliance is switched on.

Why does my Bosch Coffee Maker require descaling so frequently?
- S

  If your Bosch Coffee Maker frequently indicates that descaling is necessary, it may be due to the water being too hard. To resolve this, insert a water filter and configure the settings accordingly in the menu.
