Abstract

A laundry appliance includes a filter that accumulates microparticles in a fluid path, a pressure sensor having a membrane that moves from an initial position toward a saturated position in response to the accumulation of the microparticles, an arm operably coupled with the pressure sensor, and a retention feature interposing the arm and the filter to operably couple the pressure sensor with the filter, wherein the retention feature maintains the membrane in the saturated position in response a threshold saturation of the filter with the microparticles.
