Part number needed for air/water inlet cover

Hello,

We have had a mouse (some mice?) entering our dishwasher tub through the air/water inlet. There is a small inlet cover/grill/screen that they have gnawed away at over time in order to enter the tub, but now they’re able to simply push on it and it pops out into the tub.

Pest problems notwithstanding, I’d like to replace the inlet cover/screen (and set some mousetraps). However, I’m unable to find the specific part for the cover anywhere. I should mention that I ordered the entire air/water inlet assembly thinking it might include the cover; alas, it did not. Here’s a link a picture of the gnawed part in case someone wiser than me can recognize it:



Thanks,
Cody
