Water was gushing from under washer. Went online to research problem. After review I removed cabinet and discovered that mice had eaten through 2 hoses. Ordered replacement hoses and installed then (easy). Filled tub to test hoses and it overflowed (great!!). Going back online discovered AppliancePartsPros video on pressure switch replacement procedure. I ordered the parts (arrived next day... surprise), and installed in less than 5 minutes. I was a bit intimidated at first about doing DIY; but removing the cabinet requires removing 2 plastic trim pieces, 2 screws, 2 spring clips, tilting cabinet forward about 15 degrees and lift off. Tools required were a Philips and blade screwdriver, and pair of pliers. Replacing the switch was very simple... watch the video.
