Dishwasher Parts

This is a replacement part for a Panasonic built-in dishwasher.
We've been carefully using our 16-year-old dishwasher.
The cleaning power had decreased, and upon investigation, we found that the part that sprays hot water during the wash cycle was broken.
Parts are typically kept in stock for 10 years, so I didn't expect to find a part for a 16-year-old model, but I thought maybe and purchased it from the Panasonic store.
When it arrived and I tried to fit it, it didn't match, as expected.
Since it would be a waste to just throw it away, I'd like to offer it to someone who might be looking for the same part.
