The symptom this code usually arrives with
A code names the subsystem; the symptom is what sent you to look at the display in the first place. That page says what it usually turns out to be, cheapest cause first.

Film, grit or dishes still dirty Dishwasher not cleaning properly
Dishes coming out gritty, cloudy or with food still on them. In a hard-water city a good share of this is scale and detergent rather than a failed part — and the machine will eventually tell you so with a code of its own.
- Grit left in glasses and cups
- A white film on everything
- Food still on the lower rack

About Bosch error code E6160
What this one means
The controlled lower spray arm cannot find its reference position. It is a code the manufacturer publishes for this appliance, not one we have worked out — and it is decoded here rather than left as three characters on a display.
What the code covers
A published cause names a circuit rather than a component, which is the single most useful thing to know before ordering a part. This one covers:
- The mechanism that steers the lower arm
- Something physically fouling it
What to try yourself
- Spin the lower spray arm by hand with the rack loaded as you normally load it
- Look for a knife handle or a baking sheet hanging through the rack
Then what
This belongs to the models whose lower arm targets the dirtiest area rather than simply spinning. Something blocking its travel is the first thing to rule out and it is free.
