Important Tips for Samsung Models

  • Samsung support recommends checking drain hose, pump filter, and correct hose installation as primary steps for drain issues; if unresolved, contact Samsung support.

Possible Causes

Improper drain hose positioning causing siphoning

How to Identify: Drain hose inserted too far down the standpipe or positioned too low relative to washer; continuous siphoning causing water to exit as it enters.

Part: Drain hose / installation

Malfunctioning water level sensor or pressure switch

How to Identify: Sensor does not detect correct water level; machine may keep trying to fill and drain in response to false readings.

Part: Pressure switch / water level sensor

Control board or electronic control fault

How to Identify: Erratic signals controlling fill and drain cycles; symptom persists after fixing hoses and inlet valve.

Part: Main control board

DIY Solutions

Adjust Drain Hose Height and Position

Easy 10-20 minutes
Tools Needed: None
  1. Turn off the washing machine and ensure water supply is off.

  3. Use a multimeter to test solenoid continuity; if the valve remains open even when machine is off, replace it.
  4. Install replacement valve and reassemble washer.
⚠️ Safety First: Disconnect power before accessing internal components.

Inspect Pressure Switch / Sensor Hose

Moderate 30-60 minutes
Tools Needed: Screwdrivers, Multimeter
  1. Unplug machine and remove access panel to locate pressure switch and air dome tube.
  2. Check the air dome tube for blockages or damage and clean/replace if needed.
  3. Test the pressure switch with a multimeter for correct continuity.
  4. Replace faulty sensor if readings are outside specifications.
⚠️ Safety First: Ensure power is disconnected before inspecting electrical components.
