Bosch B36CT80SNS Ice Maker Not Working

Here is the step-by-step guide to fixing Bosch B36CT80SNS Ice Maker problems

Checking the Power and Settings 

The first step in troubleshooting your ice maker is to check its power and settings. Sometimes, a simple switch can make all the difference. Here’s what you need to do:

  • Fully remove the ice bucket.
  • Locate the small power button on the right side of the ice maker.
  • Ensure that the power button is ON. An LED should light up, indicating that your ice maker has power.

Also, confirm that the ice maker is getting power by checking for LED indicators or messages on the control panel. If you don’t see any LED light or hear any sound of water filling the ice tray, it may be an issue with power supply or the ice maker itself.

Temperature Check 

The temperature of your freezer plays a significant role in the performance of your ice maker. If the temperature is too high, your ice maker may not produce ice efficiently. Follow these steps to check and adjust the temperature:

  • Open the refrigerator door and locate the control panel.
  • Look for the temperature controls for the freezer.
  • Check the current temperature setting for the freezer; it should be between 0 and 5 degrees Fahrenheit (-18 to -15 degrees Celsius).
  • Adjust the temperature controls if necessary and wait for the temperature to stabilize.

Water Supply Inspection 

An adequate water supply is crucial for your ice maker to function correctly. If there are issues with the water supply, your ice maker may not produce ice or do so at a slower rate. Follow these steps:

  • Check the incoming water supply line to the refrigerator for kinks or blockages.
  • Ensure the water pressure at your holding tank is above 20 PSI.
  • Inspect the water line for any kinks or obstructions.
  • Check the water filter for clogs and replace it if necessary.
  • If the water dispenser is still not working, use a multimeter to test the water inlet valve for continuity.

Check Water Inlet Valve

The water inlet valve regulates the flow of water from your home supply to your refrigerator’s ice maker. If it’s defective, it can disrupt ice production. Here’s how to check it:

  • Confirm that the incoming water supply line is free from kinks and fully open.
  • Test the valve coils for continuity using a multimeter.
  • If there’s no continuity, the valve is electrically failed and should be replaced.
  • If there is continuity, the valve may still be mechanically failed, which you can test using a water inlet valve test.

Checking the Ice Maker Switch 

Sometimes, the ice maker switch can accidentally be turned off. Ensure it’s in the right position with these steps:

  • Open the freezer compartment and locate the ice maker.
  • Look for the on/off switch, which might be hidden behind the ice bucket.
  • Turn on the switch if it’s off and wait for several hours for the ice maker to start producing ice.

Inspecting the Ice Maker Assembly 

If all else fails, and your water supply and switch are in good working order, the issue might be with the ice maker assembly itself. This could require professional assistance as some parts are not sold separately.

Maintaining the Water Filter

If your Bosch B36CT80SNS refrigerator has a water filter, here’s how to remove and replace it:

  • Open the refrigerator door and locate the water filter panel.
  • Pull the panel towards you to unlock it.
  • Open the door to reveal the water filter.
  • Rotate the old water filter counterclockwise to remove it.
  • Discard the old water filter.
  • Clean the filter housing if necessary.
  • Remove the protective cap from the new water filter.
  • Insert the new water filter into the filter housing.
  • Rotate the new water filter clockwise to lock it into place.
  • Close the water filter door and ensure it’s securely latched.

After replacing the water filter, run the water dispenser until 3 gallons have been dispensed to purge air from the lines and condition the new water filter.

Other Bosch B36CT80SNS Ice Maker Issues

If you are experiencing issues with the ice maker in your Bosch B36CT80SNS refrigerator, here are some common problems and potential solutions:

Ice maker light flashing 

If the ice maker light is flashing, it could indicate that the water reservoir is empty and needs to be refilled. To resolve this, remove the ice bin and fill the water reservoir with water. After refilling, the ice maker should resume its normal operation.

Ice maker not working after replacing the water filter 

If you recently replaced the water filter and the ice maker stopped working, it is possible that the filter was not installed correctly. Ensure that the filter is properly installed, following the manufacturer’s instructions. 

Additionally, after installing a new filter, it is recommended to remove and discard the first few batches of ice to clear any air or impurities from the system.

Expert Tip How Clean Bosch B36CT80SNS 

To clean the Bosch B36CT80SNS refrigerator, it is recommended to follow the guidelines provided in the user manual specific to your model. Here are some general tips for cleaning a refrigerator:

  • Unplug the refrigerator: Before cleaning, unplug the refrigerator from the power source to ensure safety.
  • Remove food items: Take out all the food items from the refrigerator and transfer them to a cooler or another refrigerator to keep them fresh while you clean.
  • Clean the interior: Use a mild detergent and warm water solution to clean the interior surfaces of the refrigerator, including shelves, drawers, and walls. Avoid using abrasive cleaners or harsh chemicals that may damage the surfaces.
  • Clean the door seals: Wipe the door seals with a damp cloth to remove any dirt or debris. Ensure that the seals are clean and free from any obstructions to maintain a proper seal.
  • Clean the exterior: Use a soft cloth or sponge with mild detergent and warm water to clean the exterior surfaces of the refrigerator. Dry the surfaces thoroughly to prevent water spots or streaks.
  • Clean the condenser coils: The condenser coils are usually located at the back or bottom of the refrigerator. Use a vacuum cleaner with a brush attachment or a coil cleaning brush to remove dust and debris from the coils. This helps to maintain proper cooling efficiency.


In conclusion, the Bosch B36CT80SNS refrigerator ice maker not working can be a frustrating issue for users. 

From a faulty water valve to a hidden On/Off switch, there are various factors that can contribute to this problem. It is crucial to check the water valve, ensure a proper water line connection, and locate the ice maker’s On/Off switch if applicable. 

If troubleshooting steps do not resolve the issue, reaching out to Bosch customer support or referring to the user manual for specific model guidance is recommended. Restoring the functionality of the ice maker will bring back the convenience and joy of having readily available ice for refreshing beverages.
