Viking Dishwasher: not filling with water

Professional Repair Guide

What is this symptom?

If your Viking dishwasher is not filling with water, you may notice that the cycle starts but no water enters the tub. You might hear a humming sound without any water flow. This issue can stem from a closed water supply valve, a faulty water inlet valve, or problems with the float assembly or door latch.

Urgency: Medium

Important Tips for Viking Models

  • No official Viking-specific troubleshooting documentation found; general dishwasher causes apply to most models

Possible Causes

Water supply or shutoff valve closed

How to Identify: External supply valve under sink must be fully open; no water from dishwasher if valve closed or supply hose kinked.

Part: Water supply line / shutoff valve

Faulty or clogged water inlet valve

How to Identify: No water enters tub and humming might be heard; tested with multimeter for continuity; visually inspect valve and inlet screen for debris.

Part: Water inlet valve

Float or float switch malfunction

How to Identify: Float stuck down due to debris or damaged, stops inlet signal; water doesn’t fill even though supply present.

Part: Float assembly / float switch

Door latch/switch fault

How to Identify: Dishwasher won’t begin fill sequence if door not detected as closed; latch feels loose or fails to engage.

Part: Door latch/micro switch

Kinked or blocked supply hose

How to Identify: Hose under sink bent or kinked restricting flow; un-kinking restores water.

Part: Water supply hose
