What are the Primary Reasons for Bunn NHBX Coffee Maker to Leak from the Bottom?

Bunn NHBX Coffee Maker to Leak from the Bottom

Your Bunn NHBX coffee maker might start leaking from the bottom due to one or more reasons. Here, in this section, we have collated a few obvious reasons for the leakage. Some of them include the following:

Partially or Completely Damaged Silicone Seal

The most obvious or probably the only reason why your Bunn NHBX coffee maker leaks are because of the damaged silicone seal.

While your coffee maker machine is used consistently, it is continuously exposed to severe heat. And the soft silicone seal that is present between the water reservoir and the water tank starts to melt. Furthermore, when it reaches the extreme, the silicone seal starts diminishing.

After a certain point of time, the seal gets completely damaged. This phenomenon of damage is widely known as Planned Obsolescence.

Once the silicone seal of the Bunn coffee maker gets completely damaged or spoiled, you won’t get coverage from the company. In a nutshell, you probably cannot ask the manufacturers to repair the otherwise damaged silicone seal. It’s because the company doesn’t have the license to repair or replace the seal.

A Buildup of Internal Mineral Deposit

A Buildup of Internal Mineral Deposit

If you have been using your Bunn coffee maker for quite some time, it’s likely to have internal mineral deposit buildup. And this is one obvious reason that causes water to leak from the bottom as well as the sides of the coffee maker.

The primary reason behind the mineral deposit buildup is probably because of the water. Sometimes, water is induced with hard and rich minerals. And over time, these minerals get deposited within the circuit of the machine.

Furthermore, these deposits might probably cause the Bunn coffee machine to malfunction and not perform appropriately. This mainly happens because the water inside the coffee maker machine becomes incapable of flowing into the water tank.

Thus, the water inside the coffee maker machine starts coming out from the sides as well as the bottom. So we can rightfully state that the mineral deposits buildup within the coffee maker also causes water leakage.

Handling the Coffee Maker Machine Inappropriately

Handling the Coffee Maker Machine Inappropriately

If you are a novice at handling coffee machines, then you might not be familiar with the exact operations. And sometimes, using the Bunn coffee maker machine inappropriately might promote occasional wear and tear to the machine.

That’s exactly how the internal circuit of the coffee maker machine loosens and gets damaged eventually. Further, it doesn’t allow water to get inside the water tank of the Bunn coffee maker. Rather, it forces the water to come out from either the bottom or the sides of the Bunn coffee maker.

Thus we can rightfully state that handling your Bunn coffee maker improperly has a greater possibility of promoting water leakage.

Broken or Damaged Filter Holder

The NHBX coffee maker’s filter holder is made of plastic, deliberately holding the filter in an appropriate position. As the filter holder is made of a fragile component, it is likely to break very easily. Thus, it can cause water to leak from the bottom of your Bunn Coffee Maker.
