What Does Error Code F6E3 Mean on a Whirlpool Dishwasher?

No water detected — inlet / fill problem.

F6E3 fires when the control does not sense water reaching the tub within its programmed fill window, so it stops the cycle to protect the pump from running dry. The board watches the inlet valve energizing against feedback from the flow meter or fill sensor. Unlike F8E1, which flags a fill or overfill/leak fault once water is moving, F6E3 specifically means essentially no incoming flow was detected — pointing at supply, valve, or line problems rather than a sensor reading mid-fill.

Models affected: Whirlpool dishwashers using the F#E# fault-code scheme, including models such as WDF520PADM, WDT730PAHZ, WDTA50SAKZ, and WDF330PAHS
What owners report: Owners commonly report this code after the under-sink shutoff was left partly closed following plumbing work, or when the fill line got kinked when the unit was pushed back. A frequent quick win is simply opening the supply valve fully and clearing the inlet screen; a slow or clogged inlet valve can mimic a supply problem, so it's worth checking flow before replacing parts.

Frequently Asked Questions

Can I keep using my Whirlpool Dishwasher when error F6E3 appears? +
It is not advisable. The dishwasher may still power on, but running it while F6E3 is active can worsen the water-inlet fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes F6E3 on a Whirlpool Dishwasher? +
Across reported Whirlpool dishwasher repairs, the most frequent is water inlet valve clogged or failed (45% of cases), supply shutoff closed or low pressure (30%), then fill line kinked / float stuck (25%). Check them in that order before replacing any parts.
F6E3 keeps coming back after a reset — what should I check next? +
A reset only clears the stored F6E3 fault; if it returns, the water-inlet problem is still present. Move on to the physical checks — check the water supply, then clean the inlet valve screen — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix Whirlpool Dishwasher error F6E3? +
A DIY repair typically runs $25–$60 in parts, versus $150–$320 for a professional service call, so handling it yourself saves around $125. Expect the work to take roughly 30–60 minutes.
Which Whirlpool Dishwasher models show error F6E3? +
F6E3 is documented on Whirlpool dishwashers using the F#E# fault-code scheme, including models such as WDF520PADM, WDT730PAHZ, WDTA50SAKZ, and WDF330PAHS. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
