Maytag Dishwasher Error Code F8 E4 — Water Supply Issue
What this means
The F8 E4 error code on Maytag dishwashers indicates the unit is not receiving enough water. This is usually caused by a closed water supply valve, a kinked inlet hose, a clogged inlet screen, or a faulty water inlet valve. It is one of the most common Maytag dishwasher errors and is typically a straightforward fix.

Step-by-step fix
4 stepsCheck the water supply valve
Locate the water supply valve under the kitchen sink (usually on the hot water line). Make sure it is fully open by turning it counterclockwise.
The valve handle should be parallel to the pipe when fully open.
Inspect the inlet hose
Pull the dishwasher out slightly and check the water supply hose running from the valve to the dishwasher for kinks or damage.
Even a slight kink can restrict water flow enough to trigger this error.
Clean the inlet valve screen
Turn off the water supply. Disconnect the supply hose from the inlet valve at the bottom of the dishwasher. Check for a small mesh filter screen inside the valve port and clean any sediment or debris.
Homes with hard water tend to accumulate mineral deposits in these screens — clean every 6 months.
Test the water inlet valve
If the supply is good and screens are clean, the inlet valve solenoid may be faulty. With the dishwasher running, listen for a click and water flow. No click means the solenoid isn't engaging.
You can test the solenoid coil with a multimeter — it should read 500–1500 ohms.
When to call a professional
If the water inlet valve needs replacement and you're not comfortable working with water connections under the dishwasher, a technician can handle it quickly.
