What Does Error Code nE Mean on a Samsung Dishwasher?

Noise sensor error — abnormal sound/vibration signal from the wash system.

The nE code fires when the control board reads an abnormal sound or vibration signature from the noise (knock) sensor mounted near the pump and motor. Rather than a flow or level fault, it flags acoustic anomalies — cavitation from insufficient water, hard debris striking the impeller, worn pump bearings, or a faulty sensor circuit. It differs from flow codes like 3C or leak-related 9E in that it monitors sound patterns, not pump feedback or water presence directly.

Models affected: Samsung dishwashers equipped with a noise/knock sensor on the wash system; the code is not specific to any single model but can appear across full-size models with this sensor.

What owners report: Owners commonly report nE after a glass breaks or a fruit pit slips past the filter, and clearing the sump often resolves it. Weak household water pressure can be a false trigger via cavitation, so it's worth confirming the fill before suspecting the sensor.

What Causes Error Code nE?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

1

Debris (glass, bone, pit) in the circulation pump 40% of cases
2

Low water level causing pump cavitation 25% of cases
3

Noise sensor or harness fault 20% of cases
4

Circulation pump bearing wear 15% of cases

How to Fix Samsung Dishwasher Error Code nE

🔧🔧 Moderate DIY Est. time: 30–60 min

⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.

1

Inspect the sump and filters

Remove the lower rack, filters, and check the sump for hard debris; clear anything around the impeller area.

⚠️ Glass shards may be present — wear gloves.
2

Verify the fill level

Start a cycle and check water reaches the base of the heating area; weak fill means inlet valve or supply problems causing cavitation noise.
3

Check or replace the noise sensor

With power off, reseat the sensor connector; replace the sensor if the error persists with a clean, properly filling machine.

⚠️ Unplug or switch off the breaker before removing panels.

How to Reset Error Code nE

Power off at the breaker for 60 seconds, then rerun a cycle.

Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.

When to Call a Professional

Grinding or screeching from the pump along with nE means pump replacement — a job best left to a technician.

Average professional repair cost for this issue: $130–$260

Frequently Asked Questions

Can I keep using my Samsung Dishwasher when error nE appears? +

You often can for a cycle or two, but the sensor issue behind nE will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.

What most commonly causes nE on a Samsung Dishwasher? +

Across reported Samsung dishwasher repairs, the most frequent is debris (glass, bone, pit) in the circulation pump (40% of cases), low water level causing pump cavitation (25%), then noise sensor or harness fault (20%). Check them in that order before replacing any parts.

nE keeps coming back after a reset — what should I check next? +

A reset only clears the stored nE fault; if it returns, the sensor problem is still present. Move on to the physical checks — inspect the sump and filters, then verify the fill level — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.

How much does it cost to fix Samsung Dishwasher error nE? +

A DIY repair typically runs $0–$40 in parts, versus $130–$260 for a professional service call, so handling it yourself saves around $130. Expect the work to take roughly 30–60 minutes.

Which Samsung Dishwasher models show error nE? +

nE is documented on Samsung dishwashers equipped with a noise/knock sensor on the wash system; the code is not specific to any single model but can appear across full-size models with this sensor.. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
