If water keeps entering or leaving a Frigidaire washer when it should not, the guide's standpipe rule is the first check: the FFFW5000 needs a standpipe at least 23.6 in (60 cm) high and no taller than 8 ft (2.4 m), and a drain that is too low lets water siphon through the tub so that water enters but the tub does not fill. The top-loader needs at least 36 in (90 cm). Also check the fill-hose connections at the faucet and washer for rubber sealing washers, and that hot and cold hoses go to the right faucets.

Before you touch a setting
Record this first — changing settings destroys the evidence
- The standpipe height and how the hose sits in it
- Whether the water stops when the faucets are closed

Model-specific
What is true of this model and not of its siblings
- Installation limits that decide siphoning
- The installation limits Frigidaire's guide gives are a minimum standpipe height of 23.6 in (60 cm) for the FFFW5000 to prevent siphoning and a maximum of 8 ft (2.4 m); for the top-loader the minimum is 36 in (90 cm). Hot and cold hoses go to the matching faucets, and rubber sealing washers must be installed at both ends of each fill hose.

Exact questions
Common questions
Why does my Frigidaire washer fill with the power off?+
A low standpipe or an incorrect drain hose lets siphoning move water through the machine; a stuck valve is the other cause.
How do I stop siphoning?+
Set the standpipe and hose as in the installation instructions.
Do the fill hoses need rubber washers?+
Yes; the guide says to check the connections and ensure the rubber sealing washers are installed.
Should I close the faucets when I am away?+
It is a sensible precaution against a stuck valve or hose failure.
