Samsung Dishwasher Error Code 4C

The 4C error code means the dishwasher's flowmeter did not detect enough water entering the tub during the fill period. The flowmeter measures water flow at approximately 237 pulses per liter, and if the required pulse count is not reached within 4 minutes, the machine stops and displays 4C. This is a water supply error, not a drain or mechanical failure.

No, you should not attempt to run the dishwasher while the 4C error is active. The machine halts the cycle because it cannot confirm proper water fill, and running it in this state will not complete a wash cycle. Address the water supply issue before restarting the appliance.

If the fix is simply opening a valve or cleaning a screen filter, there is no parts cost involved. If the water inlet valve needs replacement, parts and labor typically run between $100 and $250 depending on your location and service provider. A flowmeter replacement can be in a similar range, with total repair costs varying based on parts availability and technician rates.

Start by fully opening the water supply valve under the sink and checking the inlet hose for kinks. Next, disconnect the hose and inspect the small mesh screen filter at the connection point for debris, cleaning it if necessary. If those steps do not resolve the issue, the water inlet valve or the flowmeter sensor inside the dishwasher may need to be tested and replaced by a technician.

A reset may temporarily clear the error code display, but if the underlying water supply problem is not corrected, the 4C code will return as soon as the machine attempts to fill again. Fix the root cause first, then reset the unit by pressing the Power button or unplugging it for a few minutes.
