## How to Fix Frigidaire Error E35 (Pressure Sensor Overflow)
If your Frigidaire washing machine display is showing the error code **E35**, it indicates a problem related to the water level sensing system. While this might sound complicated, the underlying issue is often straightforward and repairable by the homeowner.

### 1. Explanation: What does the E35 code mean?
The Frigidaire E35 error code signifies a **Pressure Sensor Overflow** fault.
**In plain English:**
Your washing machine uses a small sensor (the pressure switch) to determine the water level inside the drum. It does this by measuring air pressure in a small hose attached to the bottom of the tub.
* **During normal operation,** the water rises, compresses the air in the hose, and the sensor measures that pressure.
* **The E35 error** occurs when the sensor detects pressure that is far too high—meaning the control board thinks the tub is overflowing or the sensor itself is providing a faulty reading.
**The likely culprit is the Pressure Switch itself,** though the hose or the control board could also be at fault.

### 2. Step-by-Step Fix: How to Diagnose and Resolve E35
Before ordering parts, always perform a visual check and try a power reset.
#### Step 1: Power Reset and Visual Inspection (The Quick Fix)
1. **Unplug the Washer:** Disconnect the washing machine from the power outlet for at least 5 minutes. This allows the control board to completely reset any transient errors.
2. **Inspect the Tub:** Check if there is any actual excess water in the tub. If the tub is indeed overfilled, you likely have a water inlet valve issue, but the E35 error is still caused by the pressure sensor failing to communicate the problem correctly.
3. **Check for Clogged Drains:** Ensure your drain hose is clear and not kinked, allowing water to drain properly.
4. **Plug In and Test:** Plug the washer back in and try running a short cycle. If the error returns immediately, proceed to Step 2.
#### Step 2: Locate and Inspect the Pressure Sensor System
The pressure switch is usually located under the top panel of the washing machine, near the main control board.
1. **Access the Components:**
* **Unplug the washer** before starting any disassembly.
* Consult your owner’s manual to determine how to safely remove the top panel (usually two screws at the back and sliding the panel backward).
2. **Identify the Components:** You will be looking for a small, round or rectangular device (the pressure switch) with wires and a thin, flexible rubber or plastic tube (the pressure hose) attached to it. The hose runs down to the bottom of the wash tub.
3. **Check the Pressure Hose:**
* Carefully disconnect the pressure hose from both the switch and the tub connection point.
* **Inspect the Hose for Kinks or Clogs:** Look for signs of damage, blockage, or sediment buildup within the hose. A blockage can trap high pressure, triggering the E35 error.
* **Clear the Hose:** If necessary, carefully blow air through the hose to ensure it is completely clear.
4. **Check the Tub Inlet Port:** Ensure the connection point where the hose meets the tub is also clear of lint or soap residue.
#### Step 3: Test or Replace the Pressure Switch (The Likely Repair)
If the hose is clear and the error persists, the pressure switch itself is likely malfunctioning and giving a false “overflow” reading to the control board.
**Note:** Unlike older, analog switches, most modern Frigidaire pressure switches are digital and cannot be reliably tested with a standard multimeter. Replacement is generally the most effective diagnostic step if the hose is confirmed clear.
1. **Disconnect the Wiring:** Carefully unplug the electrical harness connected to the pressure switch. Take a picture beforehand to ensure correct reassembly.
2. **Remove the Old Switch:** The switch is often held in place by a single screw or a clip.
3. **Install the New Switch:** Connect the new pressure switch, reattach the pressure hose, and reconnect the electrical harness.
4. **Reassemble and Test:** Put the top panel back on (you may wish to leave the screws out temporarily), plug the washer in, and run a test cycle. The E35 error should be resolved.
