Disposal Air Gap Hose Installation Causing Smells?

[Troodon]

Hi Everyone,

We've been noticing nasty smells off and on after we wash our dishes in the dishwasher. Egg-like smells, or sometimes just old food smells that stick to dishes and sometimes glasses. Opening the dishwasher in the morning, you can sometimes smell it from a couple yards away. We rinse the dishes really well before loading every night.

Under the counter, I noticed the hose from the air gap to the disposal (the black one in the picture) sags enough for water and debris to collect. And indeed, when I stuck my gloved finger in the hole from inside the disposal, I felt slime. I ran hot water into the air gap to flush it out.

My question is, is this sag a no-no? Could it be causing the smells? Should I try cutting the hose with a saw and reattaching it so there's a downward slope from the air gap to the disposal? I haven't been able to find much online, or in the disposal and dishwasher manuals.

Thank you for any thoughts or ideas or theories, love this forum...

You might think about replacing the 7/8" hose and routing it without the dip.

The smell in the dishwasher is not caused by the stuff after the air gap.

As a simple step, try adding a cup of laundry bleach with detergent, and doing a long wash. If that does not do it, clean the stuff hidden in the bottom. There are Youtube videos.
