Samsung Dishwasher No Water: How to Fix

Quick Answer

Samsung Dishwasher NO-WATER: When a Samsung dishwasher starts a cycle but no water enters the tub, the machine is receiving power and the control board is operating, but the water inlet valve is not opening. Samsung dishwashers display a 4C or 4E error code for water supply failures - 4C is the current code on DW80R series, while 4E was used on older Samsung models. Both codes mean the same thing: the flow sensor or tub level sensor did not register a fill within the expected time. The most comm

Samsung dishwashers use a flow meter (not just a float switch) to measure water intake volume - this is more precise than the simple float switches used by GE and Maytag. When a 4C error appears, the Samsung flow meter is reporting either no flow or insufficient flow. The 4C code on Samsung DW80R series is triggered when less than 1.2 liters of water is detected in the first 4 minutes of a cycle. This means a partially clogged inlet valve screen (which allows some but not full flow) can trigger 4C even though water is technically entering the tub - it is a Samsung-specific diagnostic nuance that differs from brands that only detect all-or-nothing fill.

What Does the NO-WATER Code Mean?

Samsung 4C or 4E error means insufficient water reached the tub. The flow meter detects partial flow as well as no flow. Check the inlet valve screen for partial blockage, not just complete blockage.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Clogged inlet valve screen (partial or full blockage)40%
Water supply shutoff valve closed or restricted24%
Water inlet valve solenoid failure14%
Household water pressure below 20 PSI12%
Flow meter failure (Samsung-specific component)10%

Symptoms You May Notice

  • 4C or 4E error code on Samsung display
  • Cycle starts but no water sound follows
  • Tub is completely dry when door is opened after error
  • Display shows error within first 4 minutes of a cycle
  • Error clears sometimes when cycle is restarted

Can you reset a Samsung dishwasher to clear the NO-WATER code?

Press Cancel to clear the 4C code. Turn off the circuit breaker for 60 seconds to fully reset the control board. Resolve the water supply issue first, then restart a cycle. If 4C returns within the first 4 minutes, the inlet valve or flow meter needs replacement - the reset alone will not resolve a hardware fault.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

1

Verify the water supply

Verify the water supply. Open the cabinet under the sink, locate the dishwasher hot water supply line, and confirm the shutoff valve is fully open (turned fully counterclockwise). Also run the hot kitchen faucet to verify strong water pressure before testing the dishwasher.

2

Inspect the water inlet valve screen

3

Test the water inlet valve solenoid

4

Test the flow meter if valve and supply are confirmed good

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

What is the difference between Samsung error 4C and 4E?
Samsung 4C and 4E are the same fault - a water supply fill failure. Samsung changed the display code from 4E to 4C on newer DW80R series models. If your Samsung model shows 4E (older DW80K or DW80H series) or 4C (newer DW80R and DW80T series), the diagnosis and repair steps are identical. Both codes mean the flow meter did not detect sufficient water entering the tub within 4 minutes.
Why does my Samsung dishwasher show 4C even though I can hear some water entering?
Samsung uses a flow meter rather than a simple float switch, so it measures water volume rather than just detecting the presence of water. The control board requires at least 1.2 liters detected within 4 minutes. A partially clogged inlet valve screen may allow a trickle of water that you can hear but that does not reach the required fill volume. This is why Samsung can show 4C even when other brands' dishwashers with the same partial blockage would fill slowly but not error out.
How do I reset the 4C error code on my Samsung dishwasher?
Press Cancel or hold Power for 3 seconds to exit the current cycle and clear the 4C code from the display. The code will return immediately on the next cycle if the underlying water supply problem has not been fixed. For a full control board reset, turn off the circuit breaker for 60 seconds. But remember - resetting the code without fixing the inlet valve, supply pressure, or flow meter will just result in the 4C code returning within 4 minutes of starting the next cycle.
