Whirlpool's own answer for a WFW9620 that seems to use too little water is that it should look low: this is a low-water-usage washer, the water level will not be as visible as in a standard deep-fill washer, and the amount varies by cycle and load size to give the best fabric care. Some models fill from the top and others from the bottom, so the water is less visible during filling. Always use HE detergent. A genuinely low fill is a different problem: F8 E1 or LO FL means low flow, so check the valves, hoses, screens and flood-safe devices.

ReversibleIt is a low-water washer; the level is not as visible as in a deep-fill machine.
Use HE detergent
ReversibleUse HE detergent, and always use it in the right dose for the load, and then test again to see whether it helped.
Check for a low-flow code
ReversibleCheck for a low flow code, since F8 E1 or LO FL means that the supply needs attention.
Clear the supply
ReversibleClear the supply, with the valves open, the hoses straight and the screens clean, and then test again to see whether it helped.
Reset the code
ReversibleReset the code, by pressing Pause or Cancel twice and the Power button once, and then test again to see whether it helped.
Model-specific
What is true of this model and not of its siblings
- The fill-hose test
- Whirlpool suggests a simple test for a suspect fill hose: with the hose uninstalled, run water through it at a sink or other source. If the water does not flow completely through or the stream is restricted, replace the hose. It is a two-minute check that separates a hose problem from a valve or supply problem.
- The WFW9620 in numbers
- Whirlpool's page lists the WFW9620HW as a 5.0 cu ft smart front-load washer with the Load & Go XL Plus dispenser and remote control through the Whirlpool app, 38 5/8 in high, 27 in wide and 33 1/4 in deep, at a closeout price of $1,279.00 on 2026-09-25 (prices change). A large drum with a small water fill is by design, because a front-loader tumbles clothes through a shallow pool instead of submerging them.
- Steam and heated cycles use their own fill
- On models with a heated or Sanitize cycle the washer fills, heats and then tumbles, so the drum can seem to hold less water than a plain wash while the heater warms it. Whirlpool says the heating time depends on incoming water temperature, load size and type, and running the hot tap at a sink for 30 seconds first shortens it. That is a timing effect, not a low fill.
