Amana Washer Error Code bF

Pressure switch fill error

Amana codesAmana washer codes

Pressure switch fill error — washtub failed to fill within 59 minutes or pressure switch contacts did not change state properly during fill.

First step from the service manual

Check to make sure water supply faucets are on, then spin out any water in the washtub (may need to unplug washer for 10 seconds to clear code).

What bF means on a Amana washer

The bF error code indicates the control board detected a pressure switch fill error. Specifically, the washer either failed to fill the washtub to the required level within 59 minutes, or the pressure switch contacts did not change state as expected during the fill cycle. The pressure switch is a sensor that monitors water level by detecting changes in air pressure inside a small tube connected to the tub. When water rises, it compresses that air and triggers the switch to signal the board that the tub is full. If the board never receives that signal, or receives it at the wrong time, it throws bF and halts the cycle.

For homeowners, this error essentially means your washer tried to fill with water but something went wrong. Either not enough water got in, or the sensor that detects the water level did not respond correctly. The most common culprit is simply a closed or partially closed water supply faucet behind the machine. It can also point to kinked inlet hoses, clogged inlet screens, or a faulty pressure switch or its connecting hose.

Start by confirming both hot and cold supply faucets are fully open. Unplug the washer for 10 seconds to clear the code, then restart. If the error returns, further inspection of the water inlet valve, pressure switch hose, and pressure switch itself is needed.

Common causes of bF

  1. 01

    Closed or restricted water supply faucets

    Wiring / connection

    If the hot or cold supply faucets behind the washer are partially or fully closed, the tub cannot fill fast enough to satisfy the pressure switch within the 59-minute window. This is the most frequent cause and requires no parts to fix.

  2. 02

    Clogged or kinked water inlet hoses

    Wiring / connection

    Sediment buildup in the inlet hose screens or a kinked hose restricts water flow into the tub, preventing the washer from filling within the allotted time. Cleaning the screens or straightening or replacing the hoses resolves this.

  3. 03

    Faulty or stuck water inlet valve

    Part replacement

    The water inlet valve controls the flow of water into the tub. If the valve solenoid fails or the valve becomes clogged internally, water flow is reduced or stopped entirely, and the tub never reaches the level needed to trip the pressure switch.

  4. 04

    Defective pressure switch or damaged pressure switch hose

    Part replacement

    If the pressure switch itself is faulty, or if the small rubber hose connecting it to the tub is cracked, kinked, or disconnected, the switch contacts will not change state correctly even when the tub fills normally. The control board interprets this as a fill failure and triggers bF.

Frequently asked questions about bF

What does the bF error code mean on an Amana washer?
The bF code means the washer experienced a pressure switch fill error. The control board detected that the washtub either failed to fill within 59 minutes, or the pressure switch contacts did not change state properly during filling. This code stops the cycle to prevent the machine from running without adequate water.
How do I fix the bF error code on my Amana washer?
Start by checking that both hot and cold water supply faucets behind the washer are fully open. Also inspect the inlet hoses for kinks and the hose screens for sediment buildup. Unplug the washer for 10 seconds to clear the bF code, then restart. If the code returns after confirming water supply is good, the water inlet valve or pressure switch likely needs to be tested and replaced.
Can I still use my Amana washer when the bF code is showing?
No, the washer will not complete a wash cycle while the bF error is active because it has detected a fill problem. Running a cycle without adequate water can damage the motor and other components. Clear the code by unplugging the washer for 10 seconds, address the root cause, and confirm the machine fills properly before running a full load.
How much does it cost to repair the bF error on an Amana washer?
If the fix is simply opening the supply faucets or cleaning inlet screens, the cost is nothing. A replacement water inlet valve typically costs $20 to $60 for the part, and a pressure switch runs $10 to $40. If you hire a technician, expect to add $75 to $150 in labor. Most homeowners comfortable with basic appliance repair can replace either part with a screwdriver and pliers after unplugging the machine.
Why does my Amana washer keep showing bF even after I reset it?
A recurring bF code after a reset means the underlying fill problem has not been resolved. After ruling out supply faucet and hose issues, the water inlet valve or pressure switch is the likely cause. Test the inlet valve for continuity with a multimeter and inspect the pressure switch hose for cracks or disconnection. A valve or switch that fails testing needs to be replaced to permanently clear the code.
