This was a dishwasher swap out. I first turned the water off to the inlet hose of the dishwasher from underneath the sink. Removed the inlet water hose from sink to dishwasher. (use wrench or adjustable wrench) Then removed the screws securing old dishwasher from the cabinetry.
I then pulled out the dishwasher from the cabinetry hole it was in.
I unplugged the power cord from the wall of the old dishwasher.
Then Ii removed the other end of inlet hose still attached to old DW (braided stainless steel) with an adjustable wrench.
Then I removed the drain hose removing clamp with a socket (you may also be able to use a flat tip screwdriver)
Then I removed the drain line to the garbage disposal/sink drain by removing a clamp.
Pull out drain hose and discard.
Now get that old worn down machine out of the way.
For replacing the new dishwasher and new hose (the new hose I bought since the old DW hose would not fit new DW) put the hose on The dishwasher outlet drain first, then tighten the clamp.
Then route the other end of the hose to the garbage disposal/sink drain (where I removed the old one from) end and tighten the clamp. Then reconnect the inlet drain hose (from the old dishwasher) to the new dishwasher. The hose has two fittings that you need a wrench or adjustable wrench for. No clamps.
Then turn the water inlet line valve to the ON position and check for leaks.
Plug the power cord into the wall for the new dishwasher, then shove the dishwasher back into the hole of the cabinetry.
Attach the two screws at the end of new dishwasher to the cabinetry to secure it in place and you’re done......
Really nothing to it
