Samsung Front Load Washer Water Level Pressure Switch Parts — Models & Compatibility

If your Samsung front load washer won't fill properly, overfills, or displays water level errors, the pressure switch is likely at fault. This hub covers the DC96-01703B pressure switch replacement — the sensor that tells your washer how much water is in the tub. It's a common failure point in Samsung WF series models, and replacing it typically fixes fill cycle issues within 20 minutes.

Is This the Right Part for Your Model?

The DC96-01703B fits most Samsung front load washers manufactured between 2008-2014, primarily the WF series. Your model number is located inside the door frame or on the back panel — it'll start with "WF" followed by three digits. Check the compatible models list below to verify fit. This switch replaces older part numbers DC96-01703F, AP4458924, and PS4217080, so if you're looking for any of those, this is your replacement.

About This Replacement Part

The water level pressure switch monitors air pressure in the tub via a small hose. When water fills the drum, air pressure increases in the hose, which triggers the switch to signal the control board. When this switch fails, you'll see erratic behavior: the washer might underfill and leave detergent on clothes, overfill and leak, or stop mid-cycle with error codes. Samsung washers are particularly sensitive to pressure switch calibration — the DC96-01703B is a direct OEM-spec replacement designed to match the original pressure thresholds. At $73.99, it's a straightforward fix compared to service call costs that often exceed $200 for the same repair.

Compatible Samsung Washer Models

This pressure switch works with the following Samsung front load washer models. If your model isn't listed but starts with "WF" and was made between 2008-2014, there's a good chance it'll fit — verify the part number on your current switch before ordering:

Installation Overview

Replacing the pressure switch doesn't require special tools — just a screwdriver and about 15-20 minutes. You'll need to remove the top panel of the washer to access the switch mounted on the right side. The trickiest part is reconnecting the small air hose without kinking it, since any air leak will cause the same symptoms you're trying to fix. Make sure the hose clicks firmly onto the switch nipple and inspect it for cracks while you're in there.

Why This Part Fails

Pressure switches fail from two main causes: moisture infiltration and diaphragm fatigue. Over time, humid air inside the washer cabinet can corrode the internal contacts. The rubber diaphragm that responds to pressure changes also hardens with age, losing its ability to actuate the switch precisely. If you've noticed your washer gradually getting worse at judging water levels — sometimes too much, sometimes too little — that's textbook pressure switch degradation. The DC96-01703B uses improved sealing compared to early Samsung switches, which should give you several more years of reliable operation.

Frequently Asked Questions

Will this fix my "LE" error code?

Not directly — "LE" indicates a motor or drain issue, not water level sensing. However, if your washer shows "1E" or "E7" (water level sensor errors), this switch is exactly what you need.

Do I need to recalibrate after installation?

No. The DC96-01703B is pre-calibrated to Samsung specs. Just install it, reconnect the air hose and wiring harness, and you're done. Run a test cycle to verify proper fill levels.

Can I test my old switch before ordering?

You can do a basic continuity test with a multimeter, but pressure switches are difficult to test accurately without specialized equipment. Given the $73.99 price and the hassle of disassembling the washer twice, most techs just replace it if symptoms point to the switch.
