Plumbing codes call for a gap between potable water and a drain. This usually looks like the distance between the faucet and the top of the sink or bathtub (one inch or more). Without the "gap", waste water could siphon back into the drinking supply. This "does" happen in situations where a city main is shut off causing a drain-down of the system with plumbing that has been done improperly. Sometimes it is a hose left in a mud puddle, or maybe a hose lying in bleach water. People have died this way. The plumbing code helps protect the general public from these dangers. Current improvements include antisiphon faucets for garden hoses, the air gap for the dishwasher, proper installation of water heater T&P relief drains, and backflow preventers for irrigation systems.

Dishwasher smells like a dirty auto repair shop

Do you have an airgap valve on top of your sink or counter? Some times routed through an exterior wall. Their purpose is to prevent dirty water coming back into the DW and sitting. You can tell by looking under the sink as well. Your DW drain should never go directly to your garbage disposal or peetrap.

Why does kitchen sink drain water from drain side to garbage disposal side

The two drains are connected, but below the disposal. Likely if it's not draining down, you still have a clog, and the person the "cleared" the drain didn't.

When dishwasher is emptying it is backing into sink

there is probably nothing wrong with Dishwasher itself.
Your Sink drain is stopped up or your Garbage disposal is clogged.
usually, dishwasher drain is connected to the Garbage Disposal, but if the dishwasher empties the water into the Garbage disposal, if its clogged then water will come out of the sink. Same if sink is clogged between sink and sewer.


If you fill up your sink and then water drains away, then you know your sink itself is not the problem. If its only the Garbage disposal side that does not drain, its the garbage disposal that is clogged.

My miele dishwasher is not draining completely after i rum the "normal" cycle. what can i do to fix?

Hi,
It is probably a drain fault. Try checking the drain spigot at the sink end where the drain hose connects as these are usually the cause of most dishwasher faults.Or else try checking the airgap at the top of your sink, if nothing there then check the end of the drain line usually connected to the garbage disposal if you have one. I would reccomend disconnecting the end of the drain line and putting it into a bucket. Let the dishwasher run for 30 seconds and if it drains then its a problem with your garbage disposal. If not contact Miele technical support nearby to troubleshoot the fault code

Miele Dishwasher G892SCU Plus Intake/Drain light keep flashing

Hello RD,
Every Miele dishwasher is designed to drain water in the first 30 seconds of any cycle. Does your intake/drain light come on at all? Miele technical services can troubleshoot the fault code if you do get an intake/drain light.
The most common issue I have seen is that the dishwasher drain line is clogged.
Solution - Try checking the airgap at the top of your sink, if nothing there then check the end of the drain line usually connected to the garbage disposal if you have one. I would reccomend disconnecting the end of the drain line and putting it into a bucket. Let the dishwasher run for 30 seconds and if it drains then its a problem with your garbage disposal. If not I would contact Miele technical support to troubleshoot the fault code

Good luck

Dble sink, one with the garbage disp. won't drain standing water

It's a drain clog within the disposal. Try a drain cleaner, if no luck, you will likely need to replace it.

Dishwasher draining into kitchen sink!

Is the water coming out the holes of the airgap "vent". If so, you have an obstruction from the hose that goes from the "vent" to the garbage disposer and is causing the drain water to back up. __________________

Dishwasher drain

take the airgap apart and clean it out if that does not fix the problem then check either your drain or your garbage disposal to make sure there are no clogs. once you find the clog you will fix the problem.
