Clogged pipe

A pipe in your coffee maker can get clogged. This happens when hard bits block the water flow. These bits come from coffee or minerals in the water. A clog stops the machine from making your brew.

To fix this, take out the pipe and clean it well. Use a brush or a piece of wire to clear away anything stuck inside. After you do this, put back the pipe and test your machine again.

Malfunctioning heating element

If your coffee brewer’s heating element is not working properly, it can cause the machine to stop pumping water. The heating element is responsible for heating up the water in the reservoir so that it can be brewed into coffee.

If the heating element is malfunctioning, it may not heat up the water to the correct temperature, which can prevent proper water flow through the machine. To fix this issue, you will need to check and fix or replace the heating element of your coffee brewer.

This should restore its functionality and allow it to pump water again.

Scale buildup

One common reason why a coffee brewer may not pump water is the accumulation of hardened minerals, known as scale buildup, inside the machine. Over time, minerals found in hard water can stick to the internal components of the coffee maker and restrict the flow of water.

This can lead to reduced or no water coming out of the machine. Regularly descaling your coffee brewer using vinegar or a descaling solution can help remove these built-up scales and restore proper water flow.

By preventing scale buildup, you can ensure that your coffee brewer continues to work efficiently and provide you with delicious cups of coffee every time.

Steps to Repair a Coffee Brewer Not Pumping Water

To repair a coffee brewer that is not pumping water, follow these steps:

1. Clean the pipe: Remove any clogs or obstructions in the pipes by gently inserting a pipe cleaner or small brush into the openings. This will allow proper water flow through the system.

2. Check and fix the heating element: Inspect the heating element for any signs of damage or malfunction. If necessary, replace it with a new one to ensure proper water heating and flow.

3. Descale the coffee brewer: Over time, scale buildup can affect the performance of your coffee brewer. Use a descaling solution or white vinegar to remove mineral deposits from internal components and improve water circulation.

4. Test your coffee brewer: After following these steps, run a test brewing cycle to check if water is now pumping properly through your coffee brewer.

Remember to always refer to your specific model’s user manual for detailed instructions on troubleshooting and repairing issues with your coffee maker.

Clean the pipe

To fix a coffee brewer that’s not pumping water, start by cleaning the pipe. Over time, mineral deposits and coffee grounds can clog the pipe, preventing water from flowing properly.

To clean the pipe, remove any detachable parts of the brewer and run warm soapy water through it. Use a brush or cloth to scrub away any buildup. Rinse thoroughly with clean water before reassembling the brewer.

This simple step can often restore proper water flow and get your coffee maker working again.

Check and fix the heating element

To check and fix the heating element in your coffee brewer, you need to ensure that it is working properly. If the heating element is faulty, it can cause issues with water pumping.

Start by unplugging the machine and allowing it to cool down completely. Once cooled, locate the heating element inside the coffee brewer. Check for any visible damage or signs of wear.

If there are any issues, such as a broken or burned out heating element, it will need to be replaced.

You can find replacement heating elements online or at a local appliance store. Make sure to purchase one that is compatible with your specific coffee brewer model. Once you have the new heating element, carefully remove the old one from its housing using appropriate tools if necessary.

Next, install the new heating element by connecting it properly and securely into place according to the manufacturer’s instructions.

Descale the coffee brewer

To descale the coffee brewer, you need to remove any mineral buildup inside the machine. This scaling can block the water flow and cause your coffee maker not to pump water properly.

To descale, you can use a solution of equal parts vinegar and water or a commercial descaling product. Fill up the water reservoir with the solution and run a brewing cycle without any coffee grounds.

Then, rinse the machine by running multiple cycles with clean water until there is no more vinegar smell. Regularly descaling your coffee brewer will prevent scaling build-up and ensure proper water flow for tasty cups of coffee every time.

Can a Lack of Pumping Water Cause a Coffee Brewer to Not Dispense Hot Water?

If your coffee brewer is not dispensing hot water, it could be due to a lack of pumping water. In such cases, repairing a coffee brewer with no hot water becomes crucial. To ensure a perfectly brewed and piping hot cup of coffee, addressing this issue promptly can save your mornings from starting on a bitter note.

Preventive Measures to Avoid Pumping Issues

To prevent future pumping issues in your coffee brewer, it is important to take some preventive measures. Use filtered water, regularly descale the machine, and clean it thoroughly to keep your coffee flowing smoothly.

By following these simple steps, you can ensure a trouble-free brewing experience every morning.

Use filtered water

Using filtered water is an important preventive measure to avoid pumping issues in your coffee brewer. Filtered water helps remove impurities, such as minerals and sediments, that can clog the machine’s pipes and valves.

When these impurities accumulate over time, they can hinder the flow of water and affect the performance of your coffee maker. By using filtered water, you can minimize the risk of clogs and ensure a smooth and consistent water flow for your brewing process.

This simple step can help maintain the efficiency and longevity of your coffee brewer.

Regularly descale the coffee brewer

To ensure that your coffee brewer stays in good working condition and continues to pump water effectively, it is important to regularly descale the machine. Descaling refers to removing any mineral deposits or scaling that may have built up inside the brewer over time.

This can happen due to the minerals present in the water you use.

When scaling occurs, it can clog the internal components of the coffee maker, including pipes and heating elements, which can affect water flow. By descaling regularly, you can prevent this from happening and ensure that your coffee maker continues to pump water smoothly.

One way to descale a coffee brewer is by using a mixture of equal parts white vinegar and water. Fill the reservoir with this solution and let it run through a brewing cycle without adding any coffee grounds.

Afterward, rinse out the reservoir thoroughly with clean water to remove any residual vinegar taste.

Clean the machine regularly

To ensure your coffee brewer continues to function properly, it’s important to clean it regularly. Regular cleaning helps prevent the build-up of mineral deposits and other debris that can clog the machine and affect water flow.

You can clean your coffee maker by wiping down the exterior with a damp cloth and using warm soapy water to clean removable parts like the carafe and filter basket. Additionally, running a cycle with vinegar or a dedicated coffee machine cleaner can help remove any built-up scale or residue inside the machine.

By keeping your coffee maker clean, you’ll not only maintain its performance but also ensure a delicious cup of coffee every time you brew.


In conclusion, if your coffee brewer is not pumping water, there are a few steps you can take to fix the issue. Clean the pipe, check and fix the heating element, and descale the machine regularly.

Additionally, using filtered water and cleaning the machine frequently can help prevent pumping issues in the future. By troubleshooting and maintaining your coffee brewer properly, you can ensure that it continues to work effectively for delicious cups of coffee every time.
