Hi there,

 

I'm dismantling and replacing my LG dishwasher sump assembly and I've come across a part on the new one that's located on the opposite side of where it's located on my current (broken) one.  As a result, I can't attach the power cable to it.  I'm going to try to get an extension for the cable, but, A: is this a bad idea in terms of power supply, and B: what the heck is the name of this part, and what is its purpose?  It's located here:

Last question: if it's a bad idea to get an extension for this power cable, what are my other options?  I cannot seem to find a sump assembly that matches the broken one, though this new one is nearly identical save for the location of this part.

 

Thanks,

 

Lunaharpua

After an exhaustive search, I've answered my first question - it's a humidity sensor.  But the question remains that it's on the wrong side of the plug.  Any suggestions?  How badly do I need a humidity sensor?  Is it optional?

 

Thanks.

The D/W is an LG LDF7811ST-01.  The new sump assembly part # is 3485ED1002B, but I can't see any part # on the one I'm replacing.  This new sump assembly seems to be the only one available for my model number, but there are two main differences - the humidity sensor location and the water guide connection, which is also in a different spot, requiring a the newly designed water guide.  

 

If there's no easy solution here, I'm considering bagging the repair and investing in a Bosch.

To clarify, I'm not replacing the D/W itself - just the sump assembly on the original D/W.  

 

After additional research, it seems the sump assembly I'm after is part number AJH31248604.  The one listed as the official replacement for my model through Sears Parts Direct does not fit my model at all.  I've let them know and ordered the correct one here.

 

In other words, problem solved.  But it should be an important caveat to anyone who might have the same problem - make sure you note the location of your humidity sensor before ordering the part, and always compare that location with the one in the photo of the replacement sump assembly.  Why they'd change the location of that element and not alter anything else on the sump assembly is beyond me.

 

Thanks for your help, Grand Master Funk.
