What is this symptom?
Experiencing a water supply fault with your Samsung washing machine? This issue, often indicated by error codes like 4E or 4C, can prevent the machine from filling with water at the start of the wash cycle. Common causes include blocked hoses, clogged filters, or issues with the water supply. Follow our guide to troubleshoot and resolve this problem quickly.
Important Tips for Samsung Models
- Common Samsung codes like 4E, 4C indicate water supply faults related to inlet supply issues or filters.
Possible Causes
Blocked, kinked, or twisted water supply hose
How to Identify: Visually inspect hose for sharp bends, kinks, or crimped sections; water doesn’t enter drum though water valve and supply are on.
Part: Water supply hose
Clogged inlet filter at hose connection
How to Identify: Remove hose from machine; filter shows debris, rust, or sediment blocking mesh; water flow poor even when supply is open.
Part: Inlet filter (mesh) at hose connection
Water supply valve closed or low home water pressure
How to Identify: External water tap not fully open; other faucets show low flow; washing machine fails to fill.
Part: Home water supply valve / plumbing
Faulty water intake valve/solenoid
How to Identify: No water enters despite good supply and open valve; controller doesn’t trigger fill; continuity test shows solenoid failure.
Part: Water inlet valve (solenoid assembly)
Home supply interruption (planned/unplanned supply outage)
How to Identify: Other household outlets also have no water; local outage reports.
Part: Municipal water supply
Internal control board or sensor (rare)
How to Identify: Error persists after all other causes ruled out; erratic error codes; no water fill though supply is good.
Part: Control board / water level sensor
