Samsung Top Load Washer 1C Pressure Switch Error Fix -... | digitalhomefaults.org

Technical Background:

The Samsung Top Load Washer utilizes a pressure sensor (or pressure switch) to detect the water level within the tub. The sensor outputs an analog voltage signal proportional to the pressure exerted by the water column. The main control board interprets this voltage to control water inlet and outlet valves. Failure occurs if the sensor output is out of range (too high or too low) or if there is a communication breakdown between the sensor and the control board. Sensor calibration drifts are more common during extreme cold temperatures found in Canadian winters.

Symptoms:

Observed error code '1C' (or '1E' on some models) displayed on the washer's control panel. Unit fails to initiate wash cycle or fills excessively/insufficiently. Water may continuously fill or drain without prompting. App-side error logs report "Pressure Sensor Fault" or similar.

Possible Causes:

Faulty pressure sensor (drifted calibration, internal short circuit).
Obstruction in the pressure sensor hose (kink, clog, debris).
Loose or corroded wiring connections to the pressure sensor.
Damaged or malfunctioning main control board.
Overfilling of the tub, causing the sensor to read an out-of-range value.
Extreme temperature fluctuations affecting sensor accuracy (Canadian winter conditions).

Solution:

1

Disconnect the washer from the power supply (breaker lockout). Verify no voltage is present using a multimeter.
2

Locate the pressure sensor, typically found near the bottom of the washer cabinet. Consult the service manual for specific location.
3

Inspect the pressure sensor hose for kinks, clogs, or damage. Clear any obstructions with compressed air or a small wire.
4

Disconnect the wiring harness from the pressure sensor. Inspect the connector pins for corrosion or damage. Clean with electronic contact cleaner if necessary.
5

Use a multimeter to measure the resistance of the pressure sensor. Compare the reading to the specifications in the service manual. Replace the sensor if the reading is out of range.
6

If the sensor tests good, suspect a faulty main control board. Replacement of the control board should be performed by a qualified technician.
7

After repairs, run a calibration cycle (if available) through the Samsung SmartThings app or service menu to calibrate the pressure sensor. Monitor water levels during the first few cycles.

Safety Warning:

Always disconnect the washer from the power supply before performing any repairs. Water and electricity are a dangerous combination. Never work on live circuits. Ensure proper grounding to prevent electrical shock. Dispose of old electronic components according to local regulations. Data privacy: Be mindful of the washer's network connectivity; change default passwords and keep firmware up to date.

Prevention:

- Regularly inspect the pressure sensor hose for kinks or damage. - Avoid overloading the washer, which can stress the pressure sensor. - Run a washer cleaning cycle with a washing machine cleaner every 1-3 months. - Before winter, insulate water pipes leading to the washer in unheated areas to prevent freezing and potential sensor damage. - Ensure the washer is level to prevent uneven water distribution and inaccurate sensor readings.

Expert Tip:

A quick way to check for a blocked pressure sensor hose is to disconnect it from the sensor and gently blow air through it. If you feel significant resistance, there is likely a blockage. You can also try using a wet/dry vacuum to clear the hose.
