What To Know
- The solenoid valve is a small valve that opens and closes to allow water to flow into the filter basket.
- To remove scale, unplug the coffee maker and fill the water reservoir with a mixture of equal parts water and white vinegar.
- A coffee maker can overflow if the carafe is broken or cracked, if the filter basket is clogged, or if there is an air lock in the water….
Coffee makers are an essential part of many morning routines. But when your coffee maker stops draining, it can be a frustrating experience. There are several reasons why your coffee maker may not be draining, and it’s important to identify the cause to find the right solution.
Clogged Filter Basket
A clogged filter basket is one of the most common reasons why a coffee maker stops draining. Over time, coffee grounds and other particles can accumulate in the filter basket, blocking the flow of water. To fix this, simply remove the filter basket and rinse it thoroughly under running water.
Faulty Water Pump
The water pump is responsible for pumping water from the reservoir to the filter basket. If the pump is faulty, it may not be able to generate enough pressure to push the water through the filter basket. To test the pump, unplug the coffee maker and remove the water reservoir. Fill the reservoir with water and plug the coffee maker back in. If the pump is working properly, you should hear a humming sound and see water flowing out of the filter basket.
Clogged Solenoid Valve
The solenoid valve is a small valve that opens and closes to allow water to flow into the filter basket. If the solenoid valve is clogged, it may not be able to open properly, preventing water from flowing through the filter basket. To clean the solenoid valve, unplug the coffee maker and remove the water reservoir. Fill the reservoir with a mixture of equal parts water and white vinegar. Plug the coffee maker back in and run a brew cycle without adding any coffee grounds. This will help to dissolve any mineral deposits or other debris that may be clogging the solenoid valve.
Kinked Water Line
The water line is the tube that connects the water reservoir to the filter basket. If the water line is kinked or blocked, it may not be able to deliver water to the filter basket. To fix this, simply straighten the water line and make sure that there are no kinks or blockages.
Air Lock
An air lock occurs when air gets trapped in the water line or filter basket. This can prevent water from flowing through the coffee maker. To fix an air lock, unplug the coffee maker and remove the water reservoir. Fill the reservoir with water and plug the coffee maker back in. Run a brew cycle without adding any coffee grounds. This will help to release any trapped air and restore proper water flow.
Broken Carafe
If the carafe is broken or cracked, it may not be able to hold the brewed coffee. This can cause the coffee maker to overflow and stop draining. To fix this, simply replace the broken carafe with a new one.
Other Causes
In some cases, a coffee maker may not be draining due to other factors, such as:
- Scale buildup: Scale is a mineral deposit that can accumulate on the heating element and other parts of the coffee maker. This can reduce the efficiency of the heating element and prevent water from flowing properly. To remove scale, unplug the coffee maker and fill the water reservoir with a mixture of equal parts water and white vinegar. Run a brew cycle without adding any coffee grounds. This will help to dissolve the scale and restore proper water flow.
- Electrical problems: If the coffee maker is not getting power, it will not be able to drain properly. Check the power cord and make sure that it is plugged into a working outlet. If the power cord is damaged, it should be replaced.
Takeaways
If your coffee maker is not draining, there are several possible causes. By following the steps outlined in this article, you can identify the cause of the problem and find the right solution. With a little troubleshooting, you can get your coffee maker back up and running in no time.
