I wanted to post this thread as an FYI for those who go to replace the drain pump which is a simple plastic pump that attaches to the side of the electric motor. I went and replaced this leaking plastic pump but when everything was said and done, I now noticed that water was leaking from the inlet and outlet rubber hoses that go into said pump. What likely happened was the rubber, being cold and older, is less flexible and malleable so the constant tension clamps that go on these rubber hoses couldn't tighten it enough to prevent it from leaking. So instead of replacing these rubber drain hoses that were now leaking but weren't before I replaced the pump, I took out a hair dryer put it on full blast heat and I heated the rubber hoses at the inlets as best as I could. I tried to get them as hot as possible, pointing the hair dryer all around the circumference of the hose where it's installed as best as I could.

After heating the rubber hoses and the constant tension metal clamps for at least like 15 minutes (Despite doing this for so long, the stuff never got hot, though it was like 60F inside the garage), I tested the washer by putting more water into it and voila, no more leaks! Really glad I decided to do this as it saved me the money and time replacing these rubber hoses!

So, do you think this repair will last?
I used to repair RADAR then they discontinued vacuum tubes. Pity

I believe it will. I guess I can post an update sometime in the future, maybe a year later or so stating whether or not the leak came back. If it has been a year and I forget to post, be sure to post in the thread asking for me to update and if I get notified, I should post an update. If it leaks before then, I'll definitely come back to post that the "repair" did not work.

Just wanted to update that this repair has continued to hold up, still does not leak and everything is still working perfectly!

Fair enough! maybe some sealant and worm drive clamps may be possible as well!

A worm drive clamp might have worked but it has been my experience with rubber hoses on cars that once the hoses get too stiff and wouldn't contour in the way I needed them to, no amount of tightening would fix that --worm drive or constant tension. These were very tight/strong constant tension clamps which is probably why I didn't even consider a worm drive clamp. I tried my best to install them exactly the way they were previously installed but it was no use, if my solution had not worked, I would have been without the washer until they could ship out and receive those hoses. Next time I work on a car and the radiator hoses start to leak, I'll do the same procedure with the hair dryer and see if it works.

What kind of machine were you working on? This is typical for Kenmore/Whirlpool with OLD Oem and New pumps, I found a simple reposition of the hose clamps on a different part of the rubber hose works all the time. The OEM hose clamps are plenty strong with tension on the hoses. Samsung seem to have very week clamps.

Samsung has weak clamps, but only on the very flexible soft rubber hoses. These seam "self sealing" to me and don't need much to hold them to me

There was no matter of positioning that would have worked as these hoses were fairly stiff and were not yielding. Maybe if I waited a few days for the rubber to eventually give way to the clamps. There was just no way I was going to leave the hoses alone and come back a day or two later to see if they finally sealed up. I should mention is was about 50-60F in the garage where the machine was located. The rubber probably would have been a bit more malleable if it was significantly warmer perhaps. I've had this issue when working with rubber hoses on cars, the rubber is just too stiff especially if it's pretty old.
