Low voltage detected — power supply problem

The most common cause of the 9E1 error on a Samsung washing machine is low household voltage — shared circuit under heavy load (~50% of cases); start with: check the outlet voltage.

What Does Error Code 9E1 Mean on a Samsung Washing Machine?

Low voltage detected — power supply problem.

The control board continuously samples incoming line voltage and flags 9E1 when it reads below the acceptable window (roughly 108V, or under 100V during high-draw phases), while 9E2 signals over-voltage. The washer halts to shield its inverter and electronics from unstable power. Unlike bE, which points to a button or interface fault, 9E1/9E2 specifically concern the AC supply itself, whether from household wiring, the circuit, or the utility, and only rarely the internal power board.

Models affected: Samsung front- and top-load washers with a digital control board that monitors input voltage, roughly 2015 onward
What owners report: Owners commonly report 9E1 appearing mid-cycle, especially during spin when current draw peaks, and often on circuits shared with other appliances or fed through an extension cord. Many find the quick win is simply relocating the washer to its own dedicated outlet, after which the code tends not to return.

What Causes Error Code 9E1?

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

  1. 1
    Low household voltage — shared circuit under heavy load 50% of cases
  2. 2
    Extension cord or undersized outlet wiring 30% of cases
  3. 3
    Voltage fluctuation from utility 15% of cases
  4. 4
    Internal power board fault 5% of cases

How to Fix Samsung Washing Machine Error Code 9E1

🔧 Easy DIY Est. time: 10–20 min
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Check the outlet voltage

    Use a multimeter on the outlet. Samsung washers require 120V (±10%), typically 108–132V. Below 100V during spin cycle is common if sharing a circuit.

    🔩 Multimeter or outlet voltage tester
  2. 2

    Move to a dedicated circuit

    Washers should be on a dedicated 20A circuit. Sharing with other appliances causes voltage sag during spin.

  3. 3

    Check power board

    If voltage is good but error persists, the internal power monitoring circuit has failed.

    🔩 Samsung power board ($80–$200)

How to Reset Error Code 9E1

Restore proper voltage and unplug for 5 minutes. Restart on a dedicated circuit.

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

Persistent 9E1 on a known-good circuit indicates an internal power regulation fault requiring professional service.

Average professional repair cost for this issue: $150–$350

Frequently Asked Questions

Can I keep using my Samsung Washing Machine when error 9E1 appears? +
It is not advisable. The washing machine may still power on, but running it while 9E1 is active can worsen the power fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes 9E1 on a Samsung Washing Machine? +
Across reported Samsung washing machine repairs, the most frequent is low household voltage — shared circuit under heavy load (50% of cases), extension cord or undersized outlet wiring (30%), then voltage fluctuation from utility (15%). Check them in that order before replacing any parts.
9E1 keeps coming back after a reset — what should I check next? +
A reset only clears the stored 9E1 fault; if it returns, the power problem is still present. Move on to the physical checks — check the outlet voltage, then move to a dedicated circuit — since the code will reappear until the root cause is resolved. This is a beginner-friendly job needing only basic hand tools.
How much does it cost to fix Samsung Washing Machine error 9E1? +
A DIY repair typically runs $0–$200 in parts, versus $150–$350 for a professional service call, so handling it yourself saves around $150. Expect the work to take about 10–20 minutes.
Which Samsung Washing Machine models show error 9E1? +
9E1 is documented on Samsung front- and top-load washers with a digital control board that monitors input voltage, roughly 2015 onward. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
