How to Fix Error F9 E1 — Step by Step

1

Step 1: Reset the Washing Machine

Begin by unplugging the washing machine from the power outlet and waiting for 30 seconds. This will reset the machine's control board and clear any temporary errors. Plug the machine back in and try to reproduce the error code. If the code persists, proceed to the next step.

Step 2: Check the Drain Pump Filter

Locate the drain pump filter, usually found at the bottom of the washing machine. Remove the filter and clean it with a soft brush or replace it if it's clogged. Check the filter housing for any blockages or debris. Use a multimeter to measure the resistance of the filter (should be around 10-20 ohms). If the resistance is higher than normal, replace the filter.

Step 3: Inspect the Drain Pump and Tub

Check the drain pump and tub for any blockages or debris. Use a drain snake or plumber's auger to clear any clogs. Inspect the tub for any signs of damage or wear. Check the drain pump's electrical connections for any signs of corrosion or damage. Use a multimeter to measure the voltage and resistance of the drain pump (should be around 120V and 0.5-1 ohms). If the readings are abnormal, replace the drain pump.

Step 4: Check the Drain Sensor

Locate the drain sensor, usually found near the drain pump. Use a multimeter to measure the resistance of the sensor (should be around 10-20 ohms). If the resistance is higher than normal, replace the sensor. Check the sensor's electrical connections for any signs of corrosion or damage.

Step 5: Check the Control Board

Visually inspect the control board for burned components, corrosion, or loose connectors. If the readings are abnormal, replace the control board. Check the board's electrical connections for any signs of corrosion or damage.

When to Call a Professional

If you're unsure about handling electrical components, or if you've tried the above steps and the error code persists, you should call a professional appliance technician to diagnose and repair the issue. They can help you identify the root cause and provide a more accurate estimate for the repair.

Field note: F9 E1 means the machine did not see a drain complete — it is not a default control-board part. On Whirlpool Washing Machines start at the filter/sump, high-loop / height of the drain hose, and the impeller. A crushed hose or a coin on the impeller looks identical to a ‘bad pump’ on a scan tool.

What this code is not

Not ‘replace the board because it will not empty.’
Not a water-inlet problem (that is a fill code).
A missing high loop that siphons, or a disposer knockout still in place, will retrip F9 E1 after any new pump.
