F8
Whirlpool Washing Machine
Severity: ModerateWhat Does This Error Mean?
The F8 error means your Whirlpool washer is not getting enough water. The machine tried to fill but didn't detect adequate water flow. This is usually a water supply issue that you can fix yourself.
Affected Models
- WTW5000DW
- WFW5620HW
- WTW4816FW
- WFW9620HW
- Most Whirlpool top-load and front-load washers
Common Causes
- The water supply faucets behind the washer are turned off or partially closed
- The water inlet hoses are kinked, bent, or frozen
- The inlet hose filter screens are clogged with sediment or mineral buildup
- The water inlet valve inside the washer has failed
- Low household water pressure (below 20 PSI)
How to Fix It
-
Check that both hot and cold water faucets behind the washer are fully open.
These are the knobs or lever handles on the wall. Turn them counterclockwise to open fully.
-
Inspect the water inlet hoses for kinks or sharp bends.
Pull the washer out slightly if needed. Straighten any kinks in the hoses.
-
Clean the inlet hose filter screens.
Turn off the water. Unscrew the hoses from the back of the washer. Pull out the small mesh screens with needle-nose pliers and rinse them clean.
-
Run a nearby faucet to check your home's water pressure.
If the flow is weak everywhere, the issue is your water pressure, not the washer.
-
Reconnect the hoses, turn on the water, and try a new cycle.
If the error returns, the water inlet valve inside the washer may need replacement.
When to Call a Professional
If you've checked the supply and cleaned the filters but the error persists, the water inlet valve may be faulty. A technician can test the valve with a multimeter. Expect repair costs of $125–$250 including parts and labor. The valve itself is usually $30–$80.
Frequently Asked Questions
What does F8 mean on a Whirlpool washer?
It means the washer is not filling with enough water. The machine detects low or no water flow coming in. Check the water supply faucets and hoses first. Clogged filter screens are the most common culprit.
Can I fix the Whirlpool washer F8 error myself?
Yes, this is one of the easiest errors to fix yourself. Most of the time it's a closed faucet, kinked hose, or dirty filter. No tools are needed except maybe needle-nose pliers for the filter screens. You only need a technician if the inlet valve has failed.
Why does my Whirlpool washer show F8 in winter?
Cold weather can cause water supply lines to partially freeze. This reduces water flow to the washer below the minimum threshold. Keep your laundry area above freezing temperatures. You can also run warm water at a nearby faucet before starting the washer.
