Error code3C
ApplianceDishwasher
3C overview
Shown as: 3C, a check of how the pump operates
Dishwashers: Modernist and Heritage 24-inch dishwashers, DDW24M99* and DDW24T99*
Kind of message: a functional check; the manual does not describe it as a failure
What the manual suggests
Turn the dishwasher off.
Restart it.
If 3C keeps showing, the next step is a technician.
Water-related codes
When water is not leaving the machine, 5C, the drain check, is the closest relative. For the incoming side, 4C is the water supply check, and AP is just a smartphone pairing message.

Model compatibility: Dacor reuses codes across series and model years, so 3C may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
