KitchenAid: a newly installed dish-care machine that won’t drain

What to do when Not Draining — Newly Installed shows on the applianceKind of codeWater supply and drain
The new appliance is reporting what it gets from the water connections behind it. A no-water or slow-fill message on the first fill usually means the supply valve is still closed or only half open, or the new line kinked when the unit slid back; a drain message means the drain hose is pinched, pushed too deep into the standpipe, or looped higher or lower than the installation instructions allow. Open the valve fully, straighten the hose, set it to the height the manual gives, and run the cycle again.

An appliance installation code is a message a new unit shows because of how it was set up: a demo mode, a water or drain alert, a vent warning or a power check.

Before you book,
in this order.
Each step comes from KitchenAid's own guidance for Not Draining — Newly Installed on its appliances. Follow it to the end: the last card says whether this is a visit.
Check the garbage disposal inlet for the knockout plug and remove it if it is still in place — this step is easy to miss on a first hookup.
Inspect the drain hose for kinking, crushing, or sitting too low, and confirm it is clamped securely.
Confirm the hose achieves a proper high loop, or is connected to an air gap, exactly as the installation instructions specify.
Run the disposal briefly to clear any food clog, then run a drain cycle; if standing water remains, book a visit rather than keep re-running cycles.

It usually turns into water supply and shutoff connection. Book with the code and the model number.
What not to do
This is specifically a newly installed unit’s drainage problem, tied to the hookup itself, not a worn drain pump or a clogged filter developing over months of use. A dishwasher that drained fine for a year and has just started backing up is a different, wear-related problem.
