Samsung Dishwasher 1E Error Code: Causes & Fix

What is the Samsung Dishwasher 1E error?#

On a Samsung dishwasher, a 1E code means the water-level sensing is off, most often because the filter at the bottom of the tub is clogged and restricting flow. The machine cannot read a normal water level, so it stops mid-cycle and dishes come out poorly washed. It is not a hazard — just a dishwasher that will not complete a cycle. The reassuring part is that the leading cause is a dirty filter you can clean yourself. Start by pulling the bottom rack and lifting out the cylindrical filter in the sump.

1E on a Samsung Dishwasher: likely causes and repair cost#

On a Samsung Dishwasher, the 1E code signals: clogged filter / water level sensor.

Typical professional repair: $100–$225 · Difficulty: moderate · often owner-fixable

Fastest thing to try first: Clean the dishwasher filter.

Symptoms that often accompany 1E: Dishwasher stops mid-cycle; Water not draining properly between cycles; Dishes not getting clean due to restricted water flow

Technician diagnostic sequence for 1E:

1. Remove the bottom rack and turn the cylindrical filter assembly counterclockwise to remove it. Clean all food debris from both the fine mesh filter and the coarse filter
2. With the filter removed, use a sponge to clean the filter well area at the bottom of the dishwasher tub. Check for broken glass or hard debris that may block the drain path
3. Locate the water level sensor float (a small plastic dome near the front-left of the tub floor). Lift it up and down — it should move freely. Clean any debris underneath that prevents it from floating properly
4. If the filter is clean and the float moves freely, the pressure switch or turbidity sensor may be faulty. These are accessed by removing the lower access panel beneath the door

Parts a technician may check or replace: Samsung DD82-01542A; Samsung DD81-02176A

Field note: Samsung dishwasher 1E codes after a recent kitchen renovation are almost always caused by construction debris (plaster dust, sawdust) in the filter. A thorough vinegar rinse cycle (2 cups on the top rack, empty machine, hot cycle) clears the residue.

How to troubleshoot the 1E error yourself#

1E is very DIY-friendly because the filter is designed to be removed. Pull the lower rack, twist out the filter assembly at the base of the tub, and rinse away the food debris and grease that collect there — a clogged filter is the top cause in the table above and this alone clears most 1E codes. Wipe out the sump and check the small water-level float nearby is not stuck with gunk. Reseat the filter with a firm twist so it locks. Run a rinse cycle to confirm. Where DIY ends is the water-level sensor itself: if the filter is spotless and the float moves freely but 1E persists, replacing that sensor is a "moderate" repair for a technician.

Is the Samsung Dishwasher 1E error worth fixing?#

1E is almost always worth resolving, and the cleaning fix is free. When the water-level sensor genuinely needs replacing, the table above lists $100 to $225 — the low end for a dishwasher. Against a new machine that is minor, so I fix it every time on a dishwasher worth keeping. For most owners the only "cost" is ten minutes cleaning the filter; a true sensor repair at $100 to $225 is still well worth it versus replacing the unit.

Samsung Dishwasher 1E: frequently asked questions#

What does the 1E error mean on a Samsung Dishwasher?#

It indicates a water-level sensing problem, most often from a clogged tub filter restricting flow. The dishwasher stops mid-cycle and cleaning suffers.

Is it safe to keep using a Samsung Dishwasher that shows the 1E error?#

There is no hazard, but cycles will not complete properly until the filter or sensor is cleared. Clean the filter before running another load.

Can I clear the 1E error myself, or do I need a technician?#

Usually yes: remove and rinse the bottom filter and check the water-level float. A failed level sensor needs a technician.

How much does it cost to repair the 1E error on a Samsung Dishwasher?#

Often free if it is just the filter. If the water-level sensor has failed, the table above lists $100 to $225.

Which parts usually fail when a dishwasher throws the 1E code?#

Most often nothing — the filter is simply clogged. When a part is involved, it is the water-level sensor from the table above.

Why does a clogged filter trigger the 1E error?#

Debris in the filter restricts water flow and skews the level the machine reads, so it cannot confirm a normal fill and flags 1E, halting the cycle.
