What Does Error Code 1E Mean on a Samsung Dishwasher?

Water inlet sensor failure.

The 1E code fires when the control board reads implausible signals from the water inlet flow sensor, which counts the volume entering during fill. If pulses fall below the expected threshold within the allotted fill time, the board flags a sensor failure rather than a simple no-water fault. This distinguishes it from supply-side leak or overfill codes like 5C: 1E points specifically at the flow sensor, its wiring, or genuinely reduced supply flow that keeps the sensor below its detection threshold.

Models affected: Samsung dishwashers using flow-sensor water metering, including models such as DW80R5060US, DW80K5050US, DW80B6060US and DW80CG4051SR
What owners report: Owners commonly report 1E appearing early in a cycle right after filling, and a partially closed supply valve, kinked hose, or clogged inlet screen is a frequent false trigger. Many find that restoring full water flow or reseating the sensor connector clears it before any part replacement is needed.

What Causes Error Code 1E?

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

  1. 1
    Inlet flow sensor failure 55% of cases
  2. 2
    Water supply issue reducing flow below sensor threshold 30% of cases
  3. 3
    Sensor connector loose 15% of cases

How to Fix Samsung Dishwasher Error Code 1E

🔧🔧 Moderate DIY Est. time: 30–60 min
Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Check water supply

    Confirm supply valve open, hose not kinked.

  2. 2

    Clean inlet screen

    Remove and clean the inlet valve mesh screen.

  3. 3

    Test flow sensor

    Disconnect and check with multimeter.

    🔩 Samsung dishwasher flow sensor ($25–$60)
  4. 4

    Replace inlet valve assembly

    If sensor is integrated with the valve.

    🔩 Samsung inlet valve ($35–$80)

How to Reset Error Code 1E

After fixing supply or replacing sensor, restart 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

If supply is confirmed and sensor replaced but 1E persists, control board water detection failed.

Average professional repair cost for this issue: $120–$250

Frequently Asked Questions

Can I keep using my Samsung Dishwasher when error 1E appears? +
You often can for a cycle or two, but the water-supply issue behind 1E will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.
What most commonly causes 1E on a Samsung Dishwasher? +
Across reported Samsung dishwasher repairs, the most frequent is inlet flow sensor failure (55% of cases), water supply issue reducing flow below sensor threshold (30%), then sensor connector loose (15%). Check them in that order before replacing any parts.
1E keeps coming back after a reset — what should I check next? +
A reset only clears the stored 1E fault; if it returns, the water-supply problem is still present. Move on to the physical checks — check water supply, then clean inlet screen — 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 1E? +
A DIY repair typically runs $25–$80 in parts, versus $120–$250 for a professional service call, so handling it yourself saves around $95. Expect the work to take roughly 30–60 minutes.
Which Samsung Dishwasher models show error 1E? +
1E is documented on Samsung dishwashers using flow-sensor water metering, including models such as DW80R5060US, DW80K5050US, DW80B6060US and DW80CG4051SR. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
