The water inlet valve circuit shows current outside its range.
Model compatibility: Viking reuses codes across series and model years, so 4-4 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
Inlet valve current sense is out of range.
Water enters a Viking dishwasher through the inlet valve (the fill valve), which is operated electrically. With 4-4, the control measured the current on that valve’s circuit and found it outside the expected range.
4-4 versus 2-2
People confuse these, though they come from separate tests. A 2-2 comes from the level check, where no fill registered. A 4-4 comes from testing the valve circuit electrically, and nothing about the supply of water appears in Viking’s list for it. Tap and hose already checked, and 4-4 still showing? Then you have the right page.

Valve details
The VDB451 manual describes a 120-volt valve fixed with two Torx screws to the back frame of the base; its coil reads around 1.1K ohms, while 0 ohms calls for a new valve. The VDB200 manual asks just for the connections and that 1.1K figure. Getting there involves turning the dishwasher onto its back and taking out the base pan and moisture sensor, which makes this clearly a job for a technician.
Before you call
Cycle the breaker: off, then on, once.

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.
