Samsung Refrigerator: not filling water pitcher

Professional Repair Guide

What is this symptom?

Is your Samsung refrigerator's AutoFill water pitcher not filling as expected? This common issue can leave your pitcher empty or only partially filled. Possible causes include the AutoFill feature being turned off, a disconnected or inadequate water supply line, or a clogged water filter. Understanding these causes can help you troubleshoot effectively.

Urgency: Medium

Important Tips for Samsung Models

  • Many Samsung models default AutoFill feature Off until water line is connected and feature activated; also some have moisture sensors that disable averaging when water is present.

Possible Causes

AutoFill feature turned off

How to Identify: Check the refrigerator’s control panel or settings menu to see if the AutoFill Pitcher or Auto Water Fill setting is enabled; if off, water won’t fill the pitcher.

Part: Control panel settings / AutoFill function

Water line not connected or inadequate supply

How to Identify: Test the regular water dispenser; if no water dispenses or flow is weak, the water line may be disconnected, kinked, or the supply valve off.

Part: Water supply line

Clogged or contaminated water filter

How to Identify: Reduced flow from the water dispenser and pitcher can indicate a clogged filter; replacing the filter often improves flow.

Part: Water filter
