KitchenAid KSRP25FNSS00 - No water, no ice

KitchenAid KSRP25FNSS00 -

The water dispenser and the ice maker both stopped working simultaneously. Water filter is just a few weeks old. Neither the water dispenser line nor the ice maker line is frozen. When I press down on the water dispenser switch, it lights up and I can hear the usual hum, just no water comes out.

How can I confirm the water inlet valve is the issue?
