What are the common reasons for a Bunn coffee maker leaking from the bottom?
The most common reasons for a Bunn coffee maker leaking from the bottom include a damaged water reservoir, a faulty gasket, or a cracked brewing chamber. If the water reservoir has been dropped or exposed to extreme temperatures, it may develop cracks that lead to leaks. Similarly, wear and tear on the gaskets can prevent a proper seal, resulting in water escaping when the coffee maker is in use.
Another factor to consider is where the coffee maker is placed. If it’s on an uneven surface, it may be causing the unit to tilt slightly, leading to water pooling at the bottom. Regularly inspecting these components can help pinpoint the source of the leak before it becomes a more serious issue.
How can I tell if the leak is coming from the water reservoir?
To determine if the leak originates from the water reservoir, start by inspecting the reservoir for any visible cracks or damages. Remove the reservoir and carefully examine it under good lighting. If there are any cracks, you’re likely looking at the source of your leak, and you may need to replace the reservoir to resolve the issue.
After checking for visible damage, fill the reservoir with water and place it back onto the machine. Observe closely for any signs of leaking while the unit is brewing or heating water. If water seeps out of the reservoir but not from other areas, it confirms that the reservoir is the issue and requires maintenance or replacement.
What should I do if the gasket is worn out?
If you find that the gasket in your Bunn coffee maker is worn out, the first step is to turn off and unplug the machine.
