Dishwasher not draining through garbage disposal

[JVAD]

Hello seeking advice to fix our dishwasher / garbage disposal issue. See photo attached. Dishwasher does not drain completely due to standing water build up in the garbage disposal. When the dishwasher pumps out the water I need to run the garbage disposal to force water to climb uphill past the trap and exit to the wall outlet. Even after running the sink I still have standing water in the drain unless i run the garbage disposal to clear it. I has been installed for 7 years but only now is starting to become a issue. I always assume it was just a gravity issue because the drain outlet was higher than the output of the garbage disposal. Now that it prevents the dishwasher from clearing the dishes don't dry cause there is so much water in the bottom of the washer.

Thanks in advance for any suggestions.

Best

You have to lower that drain. Water doesn't flow uphill.

If this just started I would be suspecting a drain clog.

That drain is way too high. I'm not sure you can make the connection without opening the wall up and lowering that fitting in the wall.

Worked for 7 years and now only recently it is failing? I would not worry about the drain height (yep, it is a problem, but not his current problem).

I vote for a clog between the bottom of the dishwasher and the disposal. Either that or his 7 year old disposal is on it's last legs and is part of the problem somehow.

just realized the thread is two weeks old. JVAD, can you update us as to the solution you found please?

I agree with dschae1, I believe it's clog too. You can dumping some baking soda followed by white vinegar down the drain first. The foaming action may loosen up some stuff. I'd try this a few times. If it's more tougher stuff you can try buying one of those drain snake things to help remove. Also, try a plunger and or a singe use "zip-it" drain cleaner first. They look like long plastic sip ties with barbs along the sides.Just to check for the blocked drains. It'll really depend on what's clogging it.

LOOK at the picture. what do you see?

I see the dishwasher hose is not looped UP to the bottom of the cabinet but is dropping in a down position
I also see the drain from the disposal to the wall is to high

his plumbing is not installed correctly and will continue to clog up till it is corrected
