What 4C5 means

On Samsung DW80R and DW80T series dishwashers, including the DW80T5040US, 4C5 is a check code for water arriving while the dishwasher is not asking for any. The control counted 200 supply pulses in a mode where the fill valve should be closed. That points to the valve leaking through or cycling repeatedly. It is a diagnostic code that only some units display on screen, so many owners never see it unless a technician pulls it up.

Common causes of 4C5

  • Fill valve not closing fully when it should
  • Repeated valve cycling
  • Water pressure that pushes past a worn valve seat
  • The flow counting circuit
✓ One safe check you can try

1. Close the shutoff valve under the sink so no more water can enter. 2. Check the tub floor for standing water and leave the door open. 3. Do not start another cycle. 4. Reopen the valve only when we are ready to test. 5. Call us to look at the fill valve.

! Why to stop there
  • A closed valve stops the water but does not tell us whether the valve or the counting circuit is responsible.
  • We test whether the valve closes fully and whether the pulse count is honest.
  • The price is written and agreed before work, and 30 days of workmanship coverage follows.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

4C54C5 questions
Why does it say the dishwasher took in water when it was idle?

The control counts pulses from the fill path. Enough pulses while no fill was requested suggests the valve is letting water through or opening repeatedly.

Can this flood my kitchen?

A leaking valve can keep adding water. Shutting the supply valve under the sink while you wait is a sensible step, and we check the tub and floor for water.

Will I see 4C5 on my display?

Only some units show it. If yours does not, we can still read it, and it tells us where to begin. Our technician can pull the stored check codes and confirm what the control counted.
