Samsung Dishwasher: water pooling when off
What is this symptom?
Experiencing water pooling at the bottom of your Samsung dishwasher even when it's off? This issue can stem from several causes, including clogged filters, kinked drain hoses, or malfunctioning drain pumps. While some residual water may be normal, significant pooling indicates a need for troubleshooting to ensure your dishwasher operates efficiently.
Important Tips for Samsung Models
- Samsung support documents note that the machine drains leftover water at the start of a cycle; poor drainage typically relates to installation issues such as hose configuration.
- Some Samsung models use sensors to detect leaks; water in base pan can trigger continuous drain behavior unrelated to simple standing water.
Possible Causes
Clogged filter or debris trap
How to Identify: Water remains above the filter area and debris or food particles visible in the filter area; reduced or slow draining
Part: Filter / debris trap
Clogged or kinked drain hose
How to Identify: Water remains after cycle; visible bends/kinks in hose; water doesn’t drain when manually initiating drain cycle
Part: Drain hose
Malfunctioning drain pump
How to Identify: Dishwasher does not drain even when filters and hoses are clear; unusual noises from pump area
Part: Drain pump
Faulty check valve allowing backflow
How to Identify: Water appears after cycle due to backflow; drain appears clear but water returns
Part: Check valve
Normal residual water under filter area
How to Identify: Small amount of water only under filter and not above it; normal design to keep pump primed
Part: Sump area
