Common Causes of Water Reservoir Not Filling on Your Coffee Maker
When your coffee maker’s water reservoir isn’t filling, it can be frustrating. Understanding why this happens can help you fix it quickly.
Blocked Water Intake
One common reason is a blocked water intake. Coffee makers have a small hole where the water goes in. Sometimes, this hole gets clogged with minerals from the water. If you notice the reservoir not filling, check this hole. You can clean it with a small brush or a toothpick. Be gentle to avoid damaging the machine.
Airlocks
Another issue could be airlocks. An airlock happens when air gets trapped in the water lines. This prevents water from flowing properly. To fix this, try turning your coffee maker on and off a few times. Sometimes, this simple action helps clear the airlock and allows the water to flow.
Broken Water Pump
A broken water pump might also be the cause. The water pump is a part that moves water from the reservoir into the coffee maker. If it’s not working, water won’t move from the reservoir. If you suspect this is the issue, it might be best to call a repair person. They can check and replace the pump if needed.
Leaks
Leaks can also prevent the reservoir from filling. Check the area around your coffee maker for any signs of water. If you see water leaking, it could be coming from the reservoir or a connecting part. Tightening any loose parts or replacing damaged seals can help fix the leak.
Incorrect Placement
Lastly, make sure the water reservoir is placed correctly. If it’s not seated properly, it might not fill. Remove the reservoir, clean it, and place it back carefully. Ensure it fits snugly into its place.
If these steps don’t solve the problem, consider referring to the coffee maker’s manual or contacting customer support for further help.
How to Fix Water Reservoir Not Filling on Your Coffee Maker
If your coffee maker’s water reservoir isn’t filling, it’s important to fix it so you can enjoy your coffee. Here’s a step-by-step guide to help you solve the problem.

Check for Blockages
First, check for any blockages in the water intake. This part of your coffee maker where the water goes in can get clogged with mineral deposits. To clean it, find the small hole or slot where water enters the machine. Use a small brush or a toothpick to gently remove any buildup around this hole. Be careful not to push debris further inside. Cleaning this area can help the water flow smoothly into the reservoir.
Remove Airlocks
Sometimes, air gets trapped in the water lines, causing an airlock. This can stop the water from flowing properly. To fix an airlock, turn your coffee maker on and off a few times. This action can help push the trapped air out of the water lines. If turning the machine on and off doesn’t work, try gently tapping the side of the coffee maker. This might help release any trapped air and allow the water to flow freely into the reservoir.
Inspect the Water Pump
The water pump is responsible for moving water from the reservoir into the coffee maker. If the pump is not working, the water won’t move as it should. To check if the pump is the issue, listen for any unusual noises when the machine is running. If you hear strange sounds or the water still won’t flow, the pump might be broken. In this case, it’s best to contact a repair technician. They can inspect the pump and replace it if needed.
Look for Leaks
Leaks around the coffee maker can also prevent the reservoir from filling. Look for any signs of water outside the machine. If you see water, it might be leaking from the reservoir or other parts. Check all connections and seals for any damage or looseness. Tighten any loose parts and replace any damaged seals to stop the leaks. Ensuring that there are no leaks will help the water stay in the reservoir and flow properly.
Ensure Proper Placement
Finally, make sure the water reservoir is properly placed. If it’s not seated correctly, it might not fill. Remove the reservoir, clean it, and carefully place it back into its position. It should fit snugly and click into place. If it’s not aligned properly, the water may not flow into it as it should.
By following these steps, you can fix most issues with the water reservoir on your coffee maker. If the problem persists, consult the coffee maker’s manual or reach out to customer support for additional help.
