What Does Error Code PE Mean on a Samsung Washing Machine?

Water pressure sensor (pressure switch) failure.

PE fires when the control board reads an out-of-range or implausible signal from the analog water-level pressure sensor, which converts tub air-column pressure into a frequency the board uses to gauge fill. The code triggers on an open, shorted, or drifting sensor, or when a kinked or blocked pressure hose prevents pressure from reaching it. Unlike OE (overflow) or nF/4E (no-fill) codes that indicate actual water problems, PE points specifically to the sensing circuit itself misreporting the level.

Models affected: Samsung top-load and front-load washers across most recent series, including models such as WF45T6000AW, WF42H5000AW, WA50R5400AV, and WA54R7600AV
What owners report: Owners commonly report PE showing up at the start of a cycle or during fill, sometimes after the machine has been moved or tilted, which can pinch the pressure hose. A frequent quick win is reseating or clearing that thin hose before assuming the sensor has failed.

What Causes Error Code PE?

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

  1. 1
    Pressure sensor failed (open or shorted) 55% of cases
  2. 2
    Pressure hose kinked or blocked 30% of cases
  3. 3
    Control board pressure sensor input failure 15% of cases

How to Fix Samsung Washing Machine Error Code PE

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

    Check the pressure hose

    The pressure hose runs from the outer tub up to the pressure sensor. Check for kinks, cracks, or blockages. Blow gently through the hose — you should hear the sensor click.

  2. 2

    Test the pressure sensor

    The sensor should audibly click when you blow into the hose connection. Test electrical continuity at each water level position.

    🔩 Multimeter
  3. 3

    Replace the pressure sensor

    The sensor is usually accessed by removing the top panel. Disconnect the hose and wiring, unscrew, and swap.

How to Reset Error Code PE

After repair, unplug for 1 minute then restart.

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 a new pressure sensor and clear hose don't resolve PE, the control board sensor input has failed.

Average professional repair cost for this issue: $150–$280

Frequently Asked Questions

Can I keep using my Samsung Washing Machine when error PE appears? +
You often can for a cycle or two, but the sensor issue behind PE will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.
What most commonly causes PE on a Samsung Washing Machine? +
Across reported Samsung washing machine repairs, the most frequent is pressure sensor failed (open or shorted) (55% of cases), pressure hose kinked or blocked (30%), then control board pressure sensor input failure (15%). Check them in that order before replacing any parts.
PE keeps coming back after a reset — what should I check next? +
A reset only clears the stored PE fault; if it returns, the sensor problem is still present. Move on to the physical checks — check the pressure hose, then test the pressure sensor — 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 Washing Machine error PE? +
A DIY repair typically runs $20–$60 in parts, versus $150–$280 for a professional service call, so handling it yourself saves around $130. Expect the work to take roughly 30–60 minutes.
Which Samsung Washing Machine models show error PE? +
PE is documented on Samsung top-load and front-load washers across most recent series, including models such as WF45T6000AW, WF42H5000AW, WA50R5400AV, and WA54R7600AV. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
