Samsung Dishwasher Error Code 1E
On WaterWall models this code means water is not getting through the fine filter, so cleaning the filter is the fix in most cases. Meanings vary a little by model line, and on some machines the same code covers a low water level, so if a clean filter does not clear it, treat it as a water-level problem.
Also shown as: IE
Common causes
- Fine filter blocked with grease and food residue
- Tub heavily soiled or dishes loaded so water cannot circulate
- Wrong detergent, or far too much of it, foaming and confusing the level reading
- Low incoming water level or weak supply
- Faulty water level sensor
What to check, in order
- Take out the filters in the bottom of the tub and wash them thoroughly under a tap.
- Make sure you are using proper dishwasher detergent, in the amount the dispenser is designed for.
- Reload the machine so dishes are spread evenly and nothing blocks the water path.
- Turn the dishwasher off, wait a few minutes, and run a normal cycle again.
- If the code returns with clean filters and normal loading, have the water level sensing checked.
Clear the code and test
- Fix what the checks above found first — a filter cleaned, a hose straightened, the spray arms freed. Clearing the code without fixing the cause only brings it back.
- Close the door, plug the dishwasher back in (or restore its breaker) and make sure the water tap is open.
- Run the shortest programme and stay nearby for the first minutes, watching for leaks and listening for the drain pump.
- If the programme finishes with no code, the fault is cleared. If the code returns, write down the code and when it appeared before calling a technician — it speeds up the diagnosis.
When to call a professional
Most cases are solved by the checks above. Book a technician if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code 1E, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.

Parts are model-specific. Find your model number first — usually on a label inside the door, on the door frame or on the back — and match the part to that number before ordering.
