What F8 means on a Frigidaire washer

The F8 error code on a Frigidaire washer indicates a water level sensor failure. The water level sensor, also called a pressure sensor, monitors the amount of water inside the drum by detecting air pressure changes in a small tube connected to the tub. The control board uses this signal to determine when to stop filling, begin agitation, and initiate the drain cycle. When the sensor's electrical characteristics fall outside acceptable parameters, the board flags an F8 fault and halts operation to prevent overfilling or running the motor dry.

The primary diagnostic test for F8 involves checking the sensor at its terminals. Between terminals 1 and 2, and between terminals 2 and 3, the capacitance should read between 40nF and 50nF. Between terminals 1 and 3, resistance should measure between 20 and 40 ohms. Readings outside these ranges confirm sensor failure. Causes can include a failed sensor, wiring harness damage between the sensor and control board, a clogged or kinked pressure hose, or water intrusion into the sensor housing that distorts its readings.

Common causes of F8

  1. 01

    Faulty water level sensor

    Part replacement

    The sensor itself has failed electrically. Capacitance between terminals 1-2 and 2-3 outside the 40nF to 50nF range, or resistance between terminals 1 and 3 outside 20 to 40 ohms, confirms the sensor needs replacement.

  2. 02

    Clogged or kinked pressure hose

    Wiring / connection

    The small plastic hose connecting the tub to the water level sensor can become blocked with detergent residue or develop a kink, preventing accurate pressure readings from reaching the sensor. Inspect the full length of the hose for obstructions or bends.

  3. 03

    Damaged wiring harness or connector

    Wiring / connection

    Wires running between the water level sensor and the control board can fray, corrode at the connector pins, or pull loose, causing an open or short circuit. Visually inspect the harness and check connector terminals for corrosion or damage.

  4. 04

    Water intrusion into the sensor housing

    Part replacement

    If moisture has entered the sensor body, it can corrupt the sensor's capacitance and resistance readings. Look for water staining or mineral deposits on the sensor exterior as a clue.

  5. 05

    Failed control board

    Part replacement

    If the sensor and wiring both test within spec, the control board itself may be unable to correctly read or process the sensor signal. This is the least likely cause and should only be considered after the sensor and harness are confirmed good.

Frequently asked questions about F8

What does F8 mean on a Frigidaire washer?
F8 indicates a water level sensor failure. The washer uses a pressure-based sensor to monitor how much water is in the tub, and the control board detected that the sensor's electrical output is outside acceptable limits. The machine shuts down to prevent overfilling or running without adequate water. Diagnostic testing focuses on capacitance between sensor terminals 1-2 and 2-3 (expected 40nF to 50nF) and resistance between terminals 1 and 3 (expected 20 to 40 ohms).
Can I fix the F8 error code myself on a Frigidaire washer?
A knowledgeable DIYer with a multimeter capable of measuring capacitance can perform the sensor diagnostics. Check the pressure hose for kinks or clogs first, then test the sensor at its terminals using the specified values. If the sensor is out of range, replacing it is straightforward on most Frigidaire models. Wiring harness repairs require some comfort working with electrical connectors.
Is it safe to use my Frigidaire washer while the F8 code is active?
No, you should not run the washer while F8 is active. Without a functioning water level sensor, the machine cannot accurately control the fill cycle, which creates a risk of overfilling and potential water damage. The washer will typically stop mid-cycle anyway, so continued use attempts are unlikely to complete a load successfully.
How much does it cost to repair an F8 error on a Frigidaire washer?
If only the pressure hose needs cleaning or repositioning, there is no parts cost. A replacement water level sensor typically runs in the range of $20 to $60 for parts, depending on the specific model. If a technician is needed for diagnosis and replacement, total repair costs including labor generally fall between $100 and $200.
Will resetting my Frigidaire washer clear the F8 error code?
A power reset may temporarily clear the F8 code, but it will return if the underlying sensor problem is not resolved. Unplugging the washer for a few minutes resets the control board, but the fault will reappear as soon as the machine attempts to read the water level again. A proper repair requires testing and correcting the sensor, hose, or wiring issue.
