Question about dishwasher hose.

Dec 23, 2007 10 Replies

Hi All, I was reading here a couple of days ago, and saw an answer from someone about water running back into dishwasher from disposer or sink. I think it was Edwin who said that the hose needs to be under the countertop. OK, I visualize that in my mind, but I'm not really sure what it means. Can somebody explain that to me? I do have a problem with water running back into my dishwasher. TIA and best to all of you during the holidays. This group has been a lifesaver to me and I appreciate all of you.

Hi, That means the discharge point is too low. Our dish washer discharge is not near the insinerator discharge. Away and above into sink dranin pipe via Y coupling.

Cheri,

In some places an air gap is required to prevent backflow into the dishwasher. If an air gap is not required then the drain hose needs to be routed up to the underside of the countertop and then back down to the sink drain or the disposal (forming a loop). If the air gap or the loop is not present then you will probably have a backflow problem.

TY, I understand what you're saying.

Cheri,

Think of the looking at the hose like a horse shoe shape (upside down). It is mounted via a strap to hold in place.

PICS ARE EASY..

My dishwasher drains to a basement washtub, unfortunately dishwasher couldnt go by sink its across the room. trust me the loop is necessary or the water will siphon from the machine

Interesting, not a single manual for a DW I've read mentions draining to a basement. Seems every one does mention using the hose in a loop

- with or without an air gap... an always mention the sink, adjacent.

I vote for the loop :)

Hi, Dish washer not near the sink? How inconvenient! Like keeping laundry washer and dryer far apart? How inconvenient!

The DW pushes final rinse water through the loop, I'm not really concerned if it drains too a basement or the sink.

Proper mounting of the hose is of concern... we all want a loop:)

The downside of the loop will drain.

our home built in 1950 has the sink base cabinet too narrow for a dishwasher. short of replacing the kitchen completely theres little we can do, but actually the dishwasher in its current location is very easy to use,''

eventually we will replace the kitchen but first we need a new furnace with air, i am sick of the twice a year lugging the window units
