Quick answer: Samsung dishwasher error code 5C: dishwasher cannot drain. The most common cause is clogged filter or sump blocking the drain. Try this first — clean the filter and sump. If that does not clear it, check the drain hose. If the code persists, call a qualified technician.

What causes the 5C error?

  • Clogged filter or sump blocking the drain
  • Kinked or blocked drain hose
  • Blocked garbage disposal or sink drain connection
  • Air gap clogged (where fitted)
  • Failed drain pump
  • Drain hose installed without a high loop, causing backflow

How to fix Samsung 5C — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Clean the filter and sump
    Remove the bottom filter, rinse it, and scoop out food and debris from the sump underneath. A clogged filter is the most common reason a Samsung dishwasher will not drain.
    Safety warning: Wear gloves - broken glass often hides in the sump.
  2. Check the drain hose
    Follow the drain hose from the dishwasher to the sink or disposal. Straighten kinks and make sure it is not crushed behind the machine.
  3. Clear the disposal or air gap
    If the dishwasher drains through a garbage disposal, run the disposal to clear it - a new disposal's knockout plug is a classic cause. If you have an air gap cap on the sink, lift it and clear any debris.
  4. Run a cancel/drain cycle
    Press and hold the start/cancel button to force a drain attempt after cleaning. If water still stands, the pump may have failed.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • 5C persists after cleaning filter, hose, and disposal
  • The drain pump makes no sound or hums without draining
  • The drain pump needs replacement
  • The control board is not running the drain cycle

Frequently asked questions

There is an inch of water in the bottom. Is that normal?

A small amount after a cycle can be normal on some models, but standing water deep enough to trigger 5C is not - the drain path is blocked or the pump has failed.

My new garbage disposal was just installed and now 5C appears. Why?

The disposal's dishwasher inlet plug (knockout) was probably never removed. It blocks the dishwasher drain completely - a very common cause.

Can too much detergent cause 5C?

Excess suds can confuse the drain sensors and slow draining. Use the recommended amount of detergent and skip pre-rinsing additives.
