First, make sure you unplug the machine. Drain all the water out thru the pump housing. There's not much room under there, so, it can be difficult to get to the clamps. Make sure you have a pair of hose clamp pliers, especially for the big clamp. You should purchase a different ring for the large end of hose, because the original type is a real pain to get back on. I'd suggest the kind that you tighten with a screw or nut driver. Remove the white ball from the original hose and install it in the new one. Place the zip tie on the outlet that connects to the sensor, making sure you reuse the foam padding. Do not pull tight until you get the sensor back in to the hose. Place clamps on the other outlets - don't tighten until up get the hose connected. Once you get the clamps in place and tighten, plug machine in a test for leaks. Nothing to it! Takes about 15 minutes.
