Is your Bunn BrewWISE coffee machine experiencing issues when pressing buttons? Are the keys not responding correctly? This is a common problem in professional kitchen environments where coffee machines are used intensively every day. Although membrane keypads are thin, durable, and easy to clean, they naturally wear out due to the constant pressure from operators and baristas. Furthermore, during cleaning processes, if water accidentally penetrates the interior of the keypad, it can damage the internal membrane and affect its proper operation.

Double membrane keypad (OEM part number 29974.0001) as well as single keyboard (OEM 36446.0000) is made  for Bunn BrewWISE coffee machines. It is manufactured using Lexan® polycarbonate with UV protection, ensuring that the colors do not fade over time and that the materials do not deteriorate, even when exposed to heat and humidity. To guarantee a durable and reliable bond, we use 3M® 467, a high-strength industrial adhesive that provides excellent adhesion without compromising the keypad’s design.

Internally, the quality is also assured. The conductive circuit traces are printed using high-purity silver ink, which enables much faster signal transmission compared to traditional carbon inks. This choice of materials not only improves the keypad’s response speed but also significantly extends its service life. Additionally, the membrane incorporates a special DuPont dielectric layer that protects the conductive lines from oxidation caused by contact with air and moisture.

Do not wait until your coffee machine completely stops working. Replace the keypad at the first sign of failure and ensure consistent and reliable performance in your professional kitchen.
