F6E3 Serious Moderate DIY

KitchenAid Dishwasher F6E3 — Suds Detected / Slow Fill

KitchenAid Dishwasher · Error code F6E3

What F6E3 Means

The control detected excessive sudsing or an abnormally slow fill — water level not reaching target within the expected time.

Symptoms

  • Lots of suds in the tub
  • Long fill times
  • Cycle pauses and restarts the fill
  • Poor wash performance

Common Causes

1
Wrong detergent (hand dish soap)

Liquid dish soap causes massive suds — most common cause.

2
Too much detergent

Over-dosing rinse aid or detergent.

3
Slow water supply

Partially closed valve or low pressure.

4
Failed OWI / pressure sensor

Sensor misreads water level.

How to Fix It

  1. Stop the cycle and confirm only dishwasher detergent (not hand soap) is in the dispenser.
  2. Open the door and sprinkle table salt over suds to break them down; run a Rinse Only cycle.
  3. Repeat rinse cycles until no suds remain.
  4. Verify the household water supply valve is fully open and pressure is normal (~40-60 psi).
  5. Reduce detergent dose if using pods or powder — most loads need less than a full pod.
  6. If suds aren't the issue, clean the OWI sensor lens in the sump.
  7. Replace the OWI sensor if cleaning doesn't help.
