How to Troubleshoot & Replace Samsung AP4342417 / DD97-00137A Dishwasher Hose Drain Assembly

We purchased a new hose and works great. 

I ordered a drain hose replacement specifically for this Samsung dishwasher. It is about 12 feet long, so you can't go to the local hardware store and find a suitable replacement. It was fairly easy to install, but it is slightly different in construction from the original. The corrugations are different style, and the outer diameter is 0.040 larger than the original. This made it a challenge to use the original clamping brackets on the washer, so I used a zip tie instead. 

Replaced hose and wrapped duct tape around hose to protect against wear from metal bracket. (Metal bracket is behind the insulation and very difficult to detect unless remove insulation on left side of machine. 

Replaced with new hose. Had to remove dishwasher from under counter and reinstall which took majority of repair time. Have a Samsung dmt300rfb, so while I had it out I disassembled and cleaned the float sensor because after awhile it gets weighted down with a sludge and you find you are getting error codes because it gets too heavy to float up enough to trip the micro switch. You can tell you have the problem when it takes two or more times to get the washer to run if at all. There is a YouTube video available that walks you through it. Not a difficult job. 

There was a hole in the drain hose. We replaced it. 

Was remodeling kitchen and needed to remove dishwasher easy enough. Put in new laminate floor sealed it u[p under the dishwasher. and thought that was the end of it WELLLLLLL to put the drain hose through the base cabinet to attach to the drain I had to climb in the corner c cabinet (just so you know a 240 # man doesn't fit in a corner cabinet door) connect the drain . all connections made filled dishwasher with 3 days of dishes and all done, UNTIL the dreaded words from the wife "I see water coming from under the dishwasher." pull it back out find hole in drain hose look up part on Appliance pros day after thanksgiving. got new part Monday morning hooked everything back up. ALL DONE Thanks Appliance Parts Pros
