Samsung Washing Machine: not stopping filling and draining
What is this symptom?
Experiencing issues with your Samsung washing machine not stopping filling and draining? This problem often arises when the washer continuously fills with water while simultaneously draining, preventing the wash cycle from completing. Common causes include improper drain hose positioning, a malfunctioning water level sensor, or control board faults. Understanding these issues can help you troubleshoot effectively.
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
- Turn off the washing machine and ensure water supply is off.
- Check the drain hose placement — ensure it is elevated and not inserted too far into the standpipe (typically ~18 inches from washer and ~6 inches into standpipe).
- Reposition the hose following manufacturer recommendations to avoid siphoning.
- Secure the hose to ensure it stays at correct height.
Test and Replace Water Inlet Valve
- Unplug the washer and shut off water supply.
- Access the water inlet valve at the back by removing rear panel according to the service manual.
- Use a multimeter to test solenoid continuity; if the valve remains open even when machine is off, replace it.
- Install replacement valve and reassemble washer.
Inspect Pressure Switch / Sensor Hose
- Unplug machine and remove access panel to locate pressure switch and air dome tube.
- Check the air dome tube for blockages or damage and clean/replace if needed.
- Test the pressure switch with a multimeter for correct continuity.
- Replace faulty sensor if readings are outside specifications.
