Hotpoint Washer Error Code PE: Pressure Sensor... | appliancefaults.com

Technical Background:

The pressure sensor monitors the water level inside the washer tub. The MCU uses the voltage signal from the pressure sensor to control water fill and prevent overflow. A fault in the sensor, wiring, or MCU can trigger the PE error. The sensor outputs a varying voltage signal, typically between 0.5V and 4.5V DC, depending on the water level.

Symptoms:

The Hotpoint washer displays the error code PE on the control panel. The washer may not fill with water correctly, may overfill, or may not start a wash cycle at all.

Possible Causes:

Faulty pressure sensor
Wiring harness issue between the pressure sensor and the main control board
Clogged or kinked pressure sensor hose
Defective main control board (MCU)
Loose connection at the pressure sensor or MCU
Water overfilling due to inlet valve problem interfering with pressure reading

Solution:

1

Unplug the washer from the 120V AC outlet.
2

Locate the pressure sensor. It is typically a small, round component with a hose and wiring connected to it. Usually found near the bottom or rear of the machine.
3

Inspect the pressure sensor hose for kinks, clogs, or damage. Disconnect the hose and blow through it to ensure it's clear. Replace if necessary.
4

Check the wiring harness and connections to the pressure sensor and the main control board (MCU) for any signs of damage or corrosion. Reseat any loose connections.
5

Use a multimeter to test the pressure sensor's resistance. A typical resistance range is between 1k and 5k ohms but refer to the service manual for exact specifications. Replace if out of range.
6

If the wiring and sensor check out, the main control board (MCU) might be the issue. Replacement will likely be required at this stage.
7

After making repairs, plug the washer back into the 120V AC outlet and run a test cycle to see if the PE error code has been resolved.

Safety Warning:

Disconnect the washer from the power supply (120V AC) before performing any repairs. This is a Lock-Out Tag-Out (LOTO) procedure. High voltage components are present, and failure to disconnect power can result in serious injury or death.

Prevention:

Regularly check the pressure sensor hose for any signs of wear and tear. Avoid overloading the washer, as this can put extra strain on the components.

Expert Tip:

Some Hotpoint washers have a service mode. Entering this mode allows you to run diagnostic tests on individual components, including the pressure sensor. Consult the service manual for the specific procedure for your model.

Frequently Asked Questions

•Where is the pressure sensor typically located on a Hotpoint washer?

The pressure sensor is usually located near the bottom or rear of the machine, often accessible from the back panel.

•What is the typical resistance range for a functioning pressure sensor?

A typical resistance range is between 1k and 5k ohms, but you should always refer to the service manual for your specific model for precise specifications.

•Can a faulty water inlet valve cause a PE error code?

Yes, if the inlet valve is leaking or not shutting off completely, it can cause the washer to overfill, which can trigger the PE error due to the pressure sensor reading an incorrect water level.
