KitchenAid Washer Error Code F8E4 — What It Means & How to Fix It

What Does This Error Mean?

F8E4 means the flowmeter in your KitchenAid washer recorded an abnormal amount of water during the fill cycle — either significantly more or less than expected. The control board stops the cycle because it cannot confirm a correct fill. A partially clogged inlet valve screen, low water pressure, or a failed flowmeter are the most common causes.

Affected Models

KitchenAid Front-Load Washer
KitchenAid KHFW Series
KitchenAid KHHW Series
KitchenAid Artisan Series Washer

Common Causes

Inlet hose filter screens are partially clogged with sediment, restricting flow below the expected rate
Household water pressure is below the 20 PSI minimum, causing a slow fill
Water supply valve is not fully open
Flowmeter impeller is stuck or worn — it is not spinning freely to generate an accurate pulse count
Flowmeter wiring harness has a loose connector, causing intermittent pulse counting

How to Fix It

Check that both water supply valves behind the washer are fully open.

A valve that is even slightly closed significantly reduces flow rate and can push the flowmeter reading below the acceptable range.
Turn off the supply valves and disconnect the inlet hoses from the back of the washer. Remove and rinse the filter screens inside the hose fittings.

Sediment and mineral deposits on the screens are a common cause of restricted flow and F8E4.
Reconnect the hoses, turn on the supply, and run a short cycle to see if F8E4 clears.

If the fill sounds normal and the cycle completes without the error, the screen was the cause.
If F8E4 returns, check household water pressure at the nearest tap.

A kitchen tap that runs slowly or with low force suggests low household pressure. Contact your water utility if pressure is consistently below 20 PSI.
If pressure and screens are fine, have a technician test the flowmeter pulse signal.

The flowmeter is located on the water inlet path. A technician can observe the pulse count during a fill to confirm whether it is reading accurately.

When to Call a Professional

If inlet filters are clear and water pressure is adequate, the flowmeter needs to be tested and likely replaced. A technician can confirm the diagnosis by observing the pulse signal during a fill cycle.

Frequently Asked Questions

What does the flowmeter do in a washing machine?

The flowmeter measures the volume of water entering the drum by counting pulses as water spins a small impeller. The control board uses this count to confirm the correct amount of water has entered before starting the wash.

Is F8E4 the same as F8E1?

They are related but different. F8E1 means the fill timed out — not enough water arrived in the allowed time. F8E4 means the flowmeter measured an abnormal volume — the fill may have completed on time but the volume was outside the expected range.

How much does a flowmeter replacement cost?

A replacement flowmeter for a KitchenAid washer typically costs $30 to $80 for the part. With technician labor, the total repair usually runs $130 to $230.
