Wife noticed water pooling around the washing machine

Unplug the washing machine. There are electrical components that can injure or kill you. Using a screw driver inserted just below the lid of the washer in the front, there are two (2) spring clips that you push on to release. Then the front of the washer tilts down and you remove it and set aside.
On the bottom right you will see the flexible, convoluted rubber hose connecting from the pump to the washer tub. Two (2) clamps hold the hose on. Remove the two clamps, install the new hose and re-install the clamps. Re-install the front panel and push into place, allowing clips to lock into the front panel.
