The 8C error on your Samsung Washer means the machine has detected a problem with water intake, usually linked to low water pressure or a faulty water level sensor. In most cases you can clear it by checking your water supply and inlet connections before calling for service.

Error code 8C
Meaning Water supply or water level sensor fault detected by the washer’s control board
Severity Medium — the washer will pause the cycle until the issue is resolved
Time to fix 10–30 minutes
Tools needed None (basic checks), adjustable pliers for hose work if needed

What the 8C error means

The 8C code appears when the washer’s control board doesn’t detect enough incoming water within the expected time, or when the water level sensor sends an inconsistent reading. This is similar in nature to other communication-style faults such as the Samsung Washer SE Error Code, where a sensor or component fails to report correctly to the main board. The washer stops the cycle as a safety measure until water flow is confirmed.

This error is common after a house-wide water shut-off, during periods of low mains pressure, or if the inlet hoses have been recently disconnected and not fully reseated.

Common causes

  • Water supply valve behind the washer is partially closed or turned off
  • Low household water pressure feeding the machine
  • Kinked, twisted, or pinched inlet hoses
  • Clogged inlet filter screens where the hoses connect to the washer
  • Faulty water level (pressure) sensor inside the unit
  • Loose wiring connector between the sensor and the main control board

How to fix the 8C error

  1. Check the water supply valves: Make sure both hot and cold water taps behind the washer are fully open. A partially closed valve is the most common cause of this code.
  2. Inspect the inlet hoses: Look for kinks, tight bends, or crushed sections along the length of the hose. Straighten them out and make sure the washer isn’t pushed too far against the wall.
  3. Clean the inlet filter screens: Turn off the water, disconnect the hoses at the back of the washer, and check the small mesh filters inside each connection point. Rinse away any debris or mineral buildup.
  4. Reset the washer: Unplug the unit for two minutes, then plug it back in. This clears temporary sensor glitches, much like the reset process used for the Samsung Washer DE Error Code.
  5. Test water pressure: Run water directly from the tap into a bucket to confirm you have adequate household pressure. Weak flow points to a plumbing issue rather than the washer itself.
  6. Call a technician if the code persists: If all connections and pressure check out fine, the water level sensor or its wiring harness may need professional inspection and replacement.

FAQ

Can I keep using the washer after an 8C error clears?
Yes, once the water supply issue is fixed and the error clears from the display, the washer should run a normal cycle without further problems.

Is 8C the same as a drainage error?
No, 8C relates to water coming into the machine, not water draining out. Drainage issues usually trigger different codes, similar to how Samsung Washer LE Error Code covers water leak detection rather than supply problems.

Will low water pressure damage my washer long-term?
Occasional low pressure won’t damage the machine, but repeated 8C errors over time can point to a sensor that needs replacing before it fails completely.
