Safety first: Turn off power and water supply before disconnecting any hoses.

Confirm water flow: Start a cycle and listen for water entering the tub. If water flows but E10 appears, the control may not be measuring volume correctly.
Locate flow meter: On many Viking models, the flow meter is integrated into the inlet assembly or mounted in-line on the fill hose inside the cabinet.
Inspect for debris: Remove the flow meter and check the internal turbine or paddle wheel for scale or debris. Clean gently with water and a soft brush.
Test flow meter signal: With a multimeter set to frequency or pulse mode (if available), spin the turbine and verify that pulses are generated. If no signal is detected, replace the flow meter.
Check wiring: Inspect the harness from the flow meter to the control board for damage or loose connections. Repair as needed.
Reassemble and test: Reinstall the flow meter, restore water and power, and run a test cycle to confirm proper filling.

E10 error with the dishwasher failing to fill to the correct level or stopping early.
