In response to Re: Sewer smell in dishwasher and garbage disposal
: I have an ISE garbage disposal installed above the trap in a single bowl kitchen sink. My dishwasher drain hose connects to the sink line above the garbage disposer. Sometimes, there is a distinct sewer gas smell in the dishwasher and also from the sink drain immediately above the disposal.

: Is it possible that the disposal unit is clearing the water out of the trap below it and the trap is not refilling to block the sewer gases ? If so, is the solution as simple as running the water longer after using the disposal ?

: Thanks.

Running the water after the grinding stops is always a good idea.
The trap is probably not siphoning out. If you see water standing in the DW, you may have a clogged or restricted drain line.
It sounds more like the disposer is causing the odor.

Found this on ISE's website

Odor from Disposer

Over time, food particles may accumulate in the grind chamber and baffle. An odor from the disposer is usually a sign of grease and food buildup, caused by insufficient water flow during and after disposer use. To clean disposer:

Turn off disposer and disconnect power supply.
Reach through sink opening and clean underside of splash baffle and inside upper lip of grind chamber with scouring pad.
Place stopper in sink opening and fill sink halfway with warm water.
Mix � cup baking soda with water. Turn disposer on and remove stopper from sink at same time to wash away loose particles.
Disposers may also be cleaned with Disposer Care�. This product is not sold by In-Sink-Erator, but is generally available in major home centers, hardware, and grocery stores. For more information on Disposer Care�, contact Iron Out, Inc. at 1-800-654-0791 or
