Potential Causes of Cuisinart Coffee Maker’s Auto-On Not Working?

Here are the factors that commonly make the auto-on feature inactive. Read about them and their solutions.

1. Fault Timer or Programming Function

The “auto-no not working” issue primarily lies with the coffee maker’s faulty timer or defective programming function. The timer and the automatic program can be interfered with by technical problems, user errors and internal component failure. As a result, they will fail to perform accurately and prevent your Cuisinart coffee maker’s auto-on function from working, according to your command.

How to fix:

• Confirm that the timer and the automatic brewing program are correctly set. Most users make a mistake when setting the AM/PM.
• Verify the programmed time, duration and other settings relevant to the auto-on feature.
• If everything seems okay, but the auto-on feature does not work, consider a factory reset of the coffee machine’s program.

2. Defective Auto On/Off Switch

You may have noticed that Cuisinart coffee makers come with dedicated Auto On/Off switches. They are very convenient since a single press activates the auto brewing cycle. Unfortunately, those buttons can be loose, stuck, or burnt accidentally. In these cases, the auto-on button will not be able to submit your command to the machine and the feature will not work accordingly.

How to fix:

• Ensure that the switch is not stuck by debris. Keep its surroundings clean.
• Disconnect and reconnect your coffee machine and press the auto-on switch again to recover minor electrical disruptions.
• If the switch is badly damaged or burnt, replace it immediately.

3. Power Supply Issue

The problematic power source is a common factor relevant to this trouble. Since coffee makers need a consistent power supply for optimal performance, any disruption in the power flow can create problems in the brewing system, including the auto-on not working. A faulty electrical outlet and power cord are two common culprits for the issue.

How to fix:

• Ensure the coffee maker is properly plugged into the outlet.
• If you suspect a power outlet to be defective, plug in the coffee maker to a different outlet and see the result.
• Check the fuse box. If the fuse is blown, replace it with a new one.
• Moreover, inspect the coffee machine’s power cord. If the cord is damaged, you have to change it.

4. Insufficient Water / Sensor Malfunction

The auto-on feature performs when everything is prepared for brewing coffee. It works like a robotic barista, but everything has to be near its hands. For example, the water level in the reservoir must be sufficient for brewing coffee. If the sensor recognizes insufficient water in the tank or the sensor does not work by chance, the auto-on feature will not work as your expected.

How to fix:

• Check whether the water tank is filled sufficiently. If not, fill it up to the recommended level.
• Moreover, inspect the water sensor carefully and find what causes it to malfunction. Ensure it is not blocked by mineral layers or corroded badly to recognize the water level. If it seems damaged, replace the sensor soon.

5. Defective Control Panel

An automated Cuisinart coffee maker’s control panel plays a major role during the operation. It receives and processes a user’s input, including the auto-on command. Unfortunately, the control panel will not respond to your input if defective. That’s why the coffee maker will not start brewing coffee automatically at your desired time.

How to fix:

• Keep your coffee maker unplugged for a few minutes and restart it.
• If it does not fix the issue, reset your coffee machine following the user manual.
• Finally, check the control panel for any loose buttons, cracks, or damaged wires. Take notes of any visible damage and talk to customer support for further instructions.

Can You Prevent the Malfunctioning of the Auto-On Feature?

There is no direct step that can prevent the issue. But you can avoid the things that cause or are relevant to it.

• Ensure that the power outlet and the cord of the coffee maker are in good condition.
• Always use the automated programs according to the manufacturer’s instructions.
• Do not use the coffee maker when it is overheated. Let it cool down.
• Fill the water reservoir properly before assigning the auto-on function.
• Do not force the coffee machine to brew excessive coffee grounds.
• Store the machine in a clean, dry and cool place when not in use.
