Our dishwasher door started making an odd gronking noise when it was opened or closed. It had done this before, so I knew what was going on: one of the sound deadening sheets inside was creeping down around the enclosure and jamming itself into the spring.
It turns out that a layer of adhesive holds the sheets in position and, in hot weather, the weight of the sheet pulls it right over the edge. They’re made of asphalt or something equally black and sticky and heavy, just what you want to dampen vibrations on those big unsupported enclosure sides.
Oddly, this is the only sheet that’s on the move. The others are pretty much stuck where they started. I don’t know if it’s hotter on this side or what’s going on.
The situation was much worse the last time; I had to hack off a huge chunk of the sheet that had buckled around the right side of the dishwasher under the fiberglass insulating blanket. The spring was pretty much encased in shredded asphalt. Not a pretty sight.
This time the sheet traveled only a few inches, just enough to hit the spring with the door about half-open. I broke off the offending part, crudely flattened the rest, and moved the entire sheet back up to the top of the enclosure.
A few strips of duct tape should hold the sheet in place until the heat relaxes the bent areas and improves its contact with the enclosure. I hope that, with most of the remaining sheet on top, rather than hanging off the side, it’ll stay in place until the dishwasher goes casters-up for the last time.
