A coffee maker is an essential appliance for many households, providing us with our daily dose of caffeine. However, when you notice water leaking from the reservoir, it can be frustrating and messy. Fortunately, there are several troubleshooting steps you can take to identify and fix the issue. In this guide, we will explore three main areas to help you troubleshoot and resolve the problem: checking the reservoir seal, inspecting the water tank, and examining the brew basket.

Coffee Maker Leaking Water from the Reservoir

Checking the Reservoir Seal

The reservoir seal plays a crucial role in preventing water from leaking out of the coffee maker. If it becomes damaged or worn out, it can lead to leaks. Here’s what you can do to troubleshoot this issue:

Examine the Seal

Start by inspecting the reservoir seal for any visible signs of damage or wear. Carefully remove the reservoir and examine the seal’s condition. Look for cracks, tears, or hardness that may indicate deterioration. If you notice any issues, it’s time to replace the seal.

Replace the Seal

To replace the reservoir seal, consult the coffee maker’s user manual for instructions specific to your model. In most cases, you can purchase a replacement seal from the manufacturer or a reputable appliance parts supplier. Follow the provided guidelines to remove the old seal and install the new one correctly. Once the new seal is in place, test the coffee maker to see if the leakage issue is resolved.

Clean the Seal and Reservoir

Sometimes, a leaking reservoir can be caused by residue or debris on the seal or inside the reservoir. If you notice any buildup, gently clean the seal and the reservoir using a mild detergent and a soft cloth. Rinse thoroughly to remove any soap residue before reassembling the coffee maker. This simple maintenance step can often resolve minor leaks.

Seek Professional Assistance

If you have inspected and replaced the reservoir seal, yet the leaking issue persists, it may be best to contact the manufacturer’s customer support or a professional appliance repair service. They can provide further guidance or arrange for a technician to diagnose and fix the problem.

Inspecting the Water Tank

The water tank is another component that can contribute to leaks in your coffee maker. Here’s what you can do to troubleshoot this area:

Check for Cracks or Damage

Carefully examine the water tank for any cracks or visible damage. Small cracks may not be immediately noticeable, so it’s essential to inspect the tank thoroughly. If you find any cracks, it is likely the source of the leakage. In such cases, it is best to replace the water tank.

Tighten or Replace the Tank Lid

Sometimes, a loose or faulty tank lid can cause water to leak from the reservoir. Ensure the lid is properly secured and tightened. If it continues to leak, consider replacing the lid if it is available as a separate part. If the lid cannot be replaced separately, replacing the entire water tank may be necessary.

Clean the Tank

Over time, mineral deposits and residue can accumulate inside the water tank, leading to leaks. Regular cleaning is essential to prevent such issues. Follow the manufacturer’s instructions to clean the tank using a mixture of vinegar and water or a recommended descaling solution. Rinse thoroughly before reassembling the coffee maker.

Contact Customer Support

If you have inspected and cleaned the water tank but the leaking problem persists, it’s advisable to contact the manufacturer’s customer support or a professional technician. They can provide further assistance or recommend suitable solutions to resolve the issue.

Examining the Brew Basket

The brew basket is where the coffee grounds are placed during the brewing process. Issues with the brew basket can sometimes cause water to leak. Consider the following troubleshooting steps:

Ensure Proper Placement

Make sure the brew basket is correctly positioned within the coffee maker. Improper alignment or loose fit can result in water leakage. Refer to the user manual for your specific model to ensure you are using the brew basket correctly.

Clean the Brew Basket

A clogged or dirty brew basket can disrupt the flow of water, leading to leaks. Remove the brew basket and clean it thoroughly. If necessary, use a small brush or toothpick to clear any clogs or debris from the tiny holes. Rinse the basket and reinsert it properly into the coffee maker.

Replace Damaged Parts

Inspect the brew basket for any signs of damage, such as cracks or holes. If you identify any defects, it’s advisable to replace the basket. Check with the manufacturer or an appliance parts supplier to find a suitable replacement. Follow the instructions provided to install the new brew basket correctly.

Professional Assistance

If you have followed the above steps and the coffee maker is still leaking from the reservoir, it may be time to seek professional assistance. Contact the manufacturer’s customer support or a qualified technician to diagnose and fix the problem effectively.


A coffee maker that leaks water from the reservoir can be a frustrating issue to deal with. However, by following the troubleshooting steps outlined in this guide, you can identify and resolve the problem. Start by checking the reservoir seal, inspecting the water tank, and examining the brew basket. Remember to consult the user manual specific to your coffee maker model for additional guidance.

In case the issue persists, don’t hesitate to seek help from the manufacturer’s customer support or a professional technician who can provide expert assistance. With proper troubleshooting, you can get your coffee maker back to its leak-free operation, allowing you to enjoy a perfect cup of coffee once again.
