14 Water system
Your appliance is equipped with water-carrying components. The water system only works if a water filter or a bypass cap is installed. Switch off ice cube production before disconnecting the appliance from the drinking water connection. → Page 22
14.1 Water filter
The water filter filters particles and the taste of chlorine out of the water. The water filter reduces further contamination, e.g., from chloramines, lead, and pharmaceutical products. Note: The water filter does not filter bacteria or microbes out of the water.
Change the water filter:
- Every 6 months.
- If it lights up.
- If the water output has visibly reduced.
Tips
- A new water filter can be purchased from our customer service, your dealer, or our website.
- If you do not want to use a water filter in your appliance, or an external water filter system is installed, you can permanently replace the water filter with a bypass cap. The bypass cap filters only large particles out of the water and can be cleaned as required.
- A bypass cap can be purchased from customer service or our website.
Filter change notification
- Every 6 months, the filter change notification will come on. Lights up. Note: Increased water consumption switches the filter change notification on sooner.
Switching off the filter change notification
- Replace the water filter.
- The bypass cap does not need to be replaced.
- Press and hold for 3 seconds.
- Goes out.
- The filter change status is reset.
Filter change status
If you replace the filter before the filter change notification, reset the filter change status.
Resetting the filter change status
- Press.
- Press.
- The submenu setting display shows “1”.
- Press.
- The submenu setting display shows “0”.
- Press.
Changing the water filter or replacing it with a bypass cap
- Reach into the recess below the filter cover, pull it forward slightly, and then down to the left.

- Pull the water filter down to the left, turn it counterclockwise by 90°, and remove it.
- Remove the water filter with care, as it is under pressure. Note: When removing it, a small amount of water may drip out of the water filter. Remove the drips of water with a dry cloth. Tip: You can dispose of the old water filter with your household garbage.

- Insert the new water filter or the bypass cap all the way into the filter opening, turn it 90° clockwise all the way, and fold it up to the right.
- Move the filter cover up to the right and slide it back all the way.
- Discard the ice cubes produced during the first 24 hours, and dispense water for 5 minutes and discard.
14.2 Water dispenser
Dispense cold water via the water dispenser.
Putting the water dispenser into operation
Note: Once the appliance has been connected or a new water filter has been installed, there will be air in the water system. Requirement: The appliance is connected to the drinking water connection.
- Keep dispensing water until it contains no more air bubbles. Remove any splashes of water with a dry cloth.
- For hygiene reasons, dispense water for 5 minutes and discard.
Dispensing water
- Press and hold the glass against the dispensing button, or hold the glass under the water dispenser and press.

Notes
- After a while of continuous dispensing, the water stops being dispensed. Wait a few seconds before dispensing water again.
- After water has been dispensed several times consecutively, water stops being dispensed. Wait a few minutes before dispensing water again.
14.3 Ice maker
Use the ice maker to produce ice cubes.
WARNING
- Rotating parts may cause injury.
- Never reach into or underneath the ice maker.
Note: The ice cube maker automatically detects that the ice storage container is full and stops producing ice cubes. It may take up to 48 hours until the ice storage container is full.
Tips
- You can accelerate ice cube production by setting a colder freezer compartment temperature or by switching on Super freezing. This slightly increases the energy consumption.
- If the ice cubes taste stale, dispose of the remaining ice cubes and the cubes produced over the next 24 hours. If the ice cubes still taste stale, change the water filter.
Putting the ice maker into operation
Notes
- Ice cube production starts as soon as the appliance is switched on and the freezer compartment has reached the set temperature.
- As soon as the freezer compartment reaches the set temperature, the first batch of ice cubes will be ready in approximately 4 hours.
- Requirement: The appliance is connected to the drinking water connection.
- For hygiene reasons, discard the ice cubes produced within the first 24 hours.
Switching on ice cube production
- Lift the ice maker cover upwards and press the ice maker button.
- The ice maker button lights up.

Note: If you press and hold the ice maker button for 3 seconds, the filter change status is reset.
Switching off ice cube production

Bosch 800 Series B36CT80SNB French Door Bottom Mount Refrigerator-FAQS
How do I adjust the temperature on my Bosch refrigerator?
Press the refrigerator temperature button repeatedly until the desired temperature is shown. The last set temperature is saved automatically.
What is the recommended temperature for a Bosch fridge and freezer?
The fridge should be set between 35–38°F (1.7–3.3°C) and the freezer at 0°F (-18°C) for optimal freshness and food safety.
Why is my Bosch refrigerator not cooling properly?
Common reasons include blocked air vents, dirty condenser coils, a malfunctioning evaporator fan, or an issue with the compressor. Ensure proper airflow and check the temperature settings.
How do I reset my Bosch 800 Series refrigerator?
Unplug the refrigerator for a few minutes and then plug it back in. For control panel or display resets, refer to the manual for the specific reset procedure.
How often should I clean the condenser coils?
Clean the coils at least once or twice a year, or more often if there’s noticeable dust or pet hair. Unplug the fridge before cleaning.
How do I make the water from the dispenser colder?
Lower the temperature in the Fresh Food compartment. The water in the dispenser tubing may take a few ounces to chill initially.
Why is my Bosch fridge running constantly?
It’s normal for the fridge to cycle frequently to maintain temperature. However, if it runs continuously, check for blocked vents, door seal issues, or dirty condenser coils.
Where is the temperature sensor located?
The sensor is typically inside the fresh food compartment, near the evaporator coil or behind the control panel. It regulates the cooling based on temperature readings.
