What this code means
The dishwasher is not receiving enough water, or the control is detecting a water-flow rate below the expected level.
Most likely causes
- The household water valve is partly or fully closed
- Low home water pressure or an interrupted water supply
- A kinked inlet hose or clogged inlet screen
- A weak water valve, flow-sensing problem or restricted inlet system
Safe checks for the owner
- Confirm the dishwasher water valve under the sink is fully open.
- Check the inlet hose for kinks and verify other fixtures have normal water pressure.
- Turn off water and power before inspecting the inlet connection or screen.
Estimated U.S. repair cost
$180–$420, depending on model, access, parts availability and local labor.
