What are the common causes of leaks in Bunn coffee makers?
The common causes of leaks in Bunn coffee makers often include faulty seals, cracked reservoirs, and misaligned components. Over time, wear and tear can lead to deterioration of the rubber seals and gaskets that prevent water from leaking out. If the coffee maker has been dropped or mishandled, physical damage might also lead to leaks, particularly in the reservoir or internal tubing.
