Whirlpool Dishwasher Error Code F17 — What It Means & How to Fix It

What Does This Error Mean?

The F17 error on your Whirlpool dishwasher means the machine started a fill cycle but did not reach the required water level within the allotted time. The dishwasher needs a certain amount of water before it can begin washing. If the water level is too low after the fill timeout, F17 is displayed and the cycle stops.

Affected Models

Whirlpool WDF series
Whirlpool WDT series
Whirlpool 6th Sense series
Most Whirlpool dishwashers

Common Causes

The water supply tap under the sink is turned off or only partially open
The inlet hose is kinked or pinched behind the dishwasher
The inlet valve filter screen is clogged with sediment
The water inlet solenoid valve has failed and is not opening
Very low household water pressure is preventing adequate fill

How to Fix It

Check under your kitchen sink for the dishwasher water supply shut-off valve. Make sure it is turned fully open (counter-clockwise).

This valve is sometimes accidentally bumped or partially closed during cabinet work.
Pull the dishwasher out slightly (with the power off) and check the inlet hose running from the valve to the dishwasher. Look for kinks or sharp bends.

A hose kinked behind the dishwasher is a common and very easy fix.
Turn off the water supply valve and disconnect the inlet hose from the dishwasher. Check the filter screen inside the hose fitting and clean it if blocked.

The filter screen is a small mesh insert — rinse it under tap water and reinstall.
Reconnect the hose and run cold water from the kitchen tap to check the pressure. Low overall household pressure can cause F17.

If your kitchen tap also has low pressure, the issue is with your home water supply — not the dishwasher.
If the supply checks out fine and F17 persists, the inlet solenoid valve has likely failed. Have a technician test and replace it.

The inlet valve opens when it receives power from the control board. A failed solenoid will not open regardless of water pressure.

When to Call a Professional

If the water supply and hose are clear but F17 persists, the water inlet valve solenoid likely needs replacement. Inlet valve replacement typically costs $100–$180 at a repair shop. A technician can test the solenoid in about 30 minutes.

Frequently Asked Questions

Why does F17 only happen on some cycles and not others?

Water pressure in your home fluctuates throughout the day. During peak usage times (morning showers, multiple taps running), pressure drops. If the dishwasher starts a fill cycle during a low-pressure moment, it may not fill in time. This is especially common if the inlet valve filter screen is partially clogged.

How do I know if my water inlet valve has failed?

Start a cycle and listen near the bottom of the dishwasher during the fill phase. You should hear the water flowing in. If you hear nothing and see F17, the inlet valve is likely not opening. A technician can confirm with a multimeter test.

Can F17 cause water damage in my kitchen?

No — F17 means the machine is NOT getting enough water, not too much. The dishwasher will simply stop the cycle without enough water to operate. There is no overflow or leak risk from F17 itself.
