TLDR:
Is there another bulletin that includes my serial number? My problem seems to match an existing service pointer but my serial number falls out of the range. Wanted to get some advice before I contact Kitchenaid tomorrow. TIA.
Amateur Diagnosis:
The dishwasher is about 2 years old, it came new as part of a kitchen renovation that occurred right before I purchased the house. The dishwasher has been working fine until the last few days. Noticed that the wood floor in front of it was getting warped. On the next wash, I looked underneath and saw the following leak (apologize for the poor video). It's towards the back, slightly off-center to the left. Original Googling pointed to a lot of diverter seal fixes for various Kitchenaid dishwashers. Upon further inspection, it actually looks like the water is coming from the left heater element attachment point.

Service Pointer #W11540964 re: heater element bushing
One of the threads pointed to a service pointer that included the following details:
KDTM404K*, serial numbers: F94601001-F952*/ All FX serial numbers/ FA01*- FA1301402
Unfortunately, it doesn't look like my serial number is part of the bulletin? KDTM404KPS 0: FA2403128
However, when I compare the photos in the bulletin, the covered photos seem to match my element bushing? Photos of both ends below:
Photo and video of the leak:
Seems to be coming from the hex-shaped area, saw the drops dripping onto that metal rail.

FIXED - Maytag Dishwasher Leaking at Heating Element MDB8959SKZ
Found that water is leaking from the bottom where the heating element enters the bottom of the unit. Seems like it should be an easy fix, but there doesn’t seem to be anything to hold the gasket in place. See the attached picture—the plastic nut holds everything in place on the outside of the...
