Flood switch tripped
When the DD24 DishDrawer from DCS shows F1, its flood switch has been activated. The user guide lists this reading for units sold in the US and Canada.
Response in the user guide
Close off the water supply to the drawer.
Disconnect power.
Call for service.
The guide gives owners nothing further to attempt with this code.
For DCS DishDrawer service in San Francisco and the Bay Area, see DCS dishwasher drawer repair or phone (415) 969-2271. Have F1, the DD24 model number and a note that the water and power are already off ready when you call.
Model compatibility: DCS reuses codes across series and model years, so F1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
The flood switch has been activated.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
