What are the common reasons for my Bunn coffee maker leaking from the bottom?
The most common reasons for a Bunn coffee maker leaking from the bottom include worn-out seals, clogged water lines, or cracks in the water reservoir. Over time, seals can dry out and become less effective, allowing water to escape from joints that are meant to be watertight. Clogged lines can also prevent water from flowing properly, leading to build-up and eventual leaks.
Another possible reason could be the placement of the coffee maker. Ensure that it’s sitting on a flat and stable surface. If the coffee maker is slightly tilted or uneven, it can lead to pooling water in unexpected places, causing it to appear like it’s leaking when, in actuality, it’s just displaced water.
How can I identify the source of the leak?
To identify the source of the leak, start by checking the water reservoir and the area around it. Look for any visible cracks or signs of damage. Next, inspect all seals and connections for wear and tear. If you notice any damp areas or drips, it may indicate the precise spot where the leak is originating.
Another method to pinpoint the leak is to run a cycle without coffee to observe where the water is escaping. Monitor closely around the drip tray and other parts of the coffee maker, as this can help in diagnosing whether the issue stems from internal components or external overflow from improper placement.
