Frigidaire Washer Error Code E35

Pressure sensor indicates water overfill

Frigidaire codesFrigidaire washer codes

Pressure sensor indicates water overfill – water inlet valve defective, air tube kinked, or main control board defective.

First step from the service manual

Check that air tube is connected properly, check for kinking and leakage; disconnect tubes and blow into them to ensure the system is unobstructed.

What E35 means on a Frigidaire washer

The E35 error code on a Frigidaire washer indicates that the pressure sensor has detected a water overfill condition. The pressure sensing system uses an air tube connected between the outer tub and a pressure transducer on the main control board. As water fills the tub, air pressure in this closed tube increases and signals the control board about the current water level. When the control board receives a signal indicating the water has exceeded the intended fill level, it triggers E35 and typically halts the fill cycle to prevent overflow damage.

The most common cause of a false or genuine overfill reading is a problem within the air tube circuit. If the tube is kinked, disconnected, or leaking, the pressure signal reaching the control board becomes inaccurate. A disconnected tube, for example, will cause the pressure sensor to read no pressure at all or ambient pressure, which can be misinterpreted as an overfill depending on the control logic. A blocked or clogged tube creates a similar problem by trapping stale pressure readings.

If the air tube checks out as unobstructed and properly connected, the fault shifts to either the water inlet valve or the main control board. A defective inlet valve that fails to close completely allows water to continue entering the tub even after the fill signal has stopped, resulting in a genuine overfill. A faulty control board may misread pressure sensor input or fail to close the inlet valve on command. Diagnosing the inlet valve involves checking that it fully closes when de-energized, while a control board fault is typically confirmed only after all other components have been ruled out.

Common causes of E35

  1. 01

    Kinked or disconnected air tube

    Wiring / connection

    The air tube connecting the tub to the pressure sensor can become kinked, pinched, or pulled loose over time, sending an inaccurate water level signal to the control board. Inspect the full length of the tube and blow through it to confirm it is clear and unobstructed.

  2. 02

    Blocked or clogged air tube

    Wiring / connection

    Residue or debris can accumulate inside the air tube, restricting airflow and causing incorrect pressure readings. Disconnecting the tube and blowing through it will reveal any blockage that needs to be cleared.

  3. 03

    Defective water inlet valve

    Part replacement

    An inlet valve that fails to fully close when de-energized will allow water to continue trickling into the tub, eventually triggering a genuine overfill condition. If the tub is actually overfilling with water, the inlet valve is the most likely culprit and will need to be replaced.

  4. 04

    Faulty pressure sensor

    Part replacement

    If the pressure transducer itself is sending incorrect readings to the control board, the board may register an overfill even when the actual water level is normal. This is typically diagnosed after the air tube has been confirmed clear and the inlet valve has been tested.

  5. 05

    Defective main control board

    Part replacement

    A malfunctioning control board may misinterpret pressure sensor signals or fail to send the correct signal to close the inlet valve. Control board failure is considered a last resort diagnosis after all other components have been eliminated.

Frequently asked questions about E35

What does E35 mean on a Frigidaire washer?
E35 means the pressure sensor has detected that the washer tub filled with more water than the intended level. The washer stops the cycle to prevent an overflow situation. The fault can stem from a kinked or blocked air tube, a water inlet valve that won't close fully, or a defective main control board. Checking the air tube first is the recommended starting point for diagnosis.
Can I fix the E35 error on my Frigidaire washer myself?
In many cases, yes. Start by locating the air tube that runs from the tub to the pressure sensor, and inspect it for kinks, disconnections, or blockages. Disconnect the tube and blow through it to confirm it is clear, then reattach it securely. If the tube is fine and the tub is genuinely overfilling, the inlet valve or control board will need further testing, which may require a qualified technician.
Is it safe to use my Frigidaire washer while the E35 code is active?
No, you should not continue using the washer until the issue is resolved. The E35 code indicates a potential overfill condition, which can lead to water leaking onto the floor and causing water damage or a slip hazard. The washer typically halts the cycle when this code appears, which is a protective response you should not override.
How much does it cost to repair a Frigidaire washer with an E35 error?
Repair cost depends on the root cause. If only the air tube needs to be cleared or repositioned, the repair may cost little to nothing beyond your time. Replacing a water inlet valve typically runs between $75 and $200 including parts and labor. A main control board replacement is more expensive, generally ranging from $150 to $400 or more depending on the model and technician rates.
Will resetting my Frigidaire washer clear the E35 error code?
A reset may temporarily clear the E35 code, but the error will return if the underlying problem is not fixed. If the inlet valve is leaking, the air tube is blocked, or the control board is faulty, the overfill condition will occur again on the next fill cycle. A reset is useful for confirming whether the fault was a one-time glitch, but persistent E35 codes require proper diagnosis and repair.
