F6-E4 means the overfill float switch has tripped. The dishwasher thinks it is overfilling, so it runs the drain pump and blocks the cycle as a flood precaution.

Quick answer: Maytag dishwasher error code F6-E4: overfill float switch tripped. The most common cause is dishwasher not level, tipping the float switch. Try this first — check that the dishwasher is level. If that does not clear it, power reset for 30 seconds.

What causes the F6-E4 error?

  • Dishwasher not level, tipping the float switch
  • Water pooled in the base pan from a small leak
  • Float stuck up because of debris or detergent gunk
  • Too much detergent causing excess suds
  • Failed float switch stuck in the tripped position
  • Fill valve letting in too much water

How to fix Maytag F6-E4 — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Check that the dishwasher is level
    Maytag lists leveling as the first check. Incorrect leveling can actuate the overfill float switch by itself. Place a level on the tub edge and adjust the feet until it is level.
    Safety warning: Turn off the breaker before adjusting feet under the unit.
  2. Power reset for 30 seconds
    Turn the breaker off for 30 seconds, then back on. If the float has dropped back down, the code clears and the dishwasher can run.
  3. Cut back on detergent
    Excess suds can lift the float. Use the measured amount of a quality detergent and skip extra rinse aid for a few loads to see if the code stays away.
  4. Look for water in the base
    If you can safely access under the unit, check the base pan for standing water and dry it. Standing water means a real leak that will trip the float again.
    Safety warning: Do not pull a built-in dishwasher out alone — get help or call a technician.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • The code returns right after a reset with no visible cause
  • You find standing water in the base pan (active leak)
  • The float switch is stuck or physically broken
  • The dishwasher is under warranty

Frequently asked questions

The dishwasher keeps draining and will not start. Is that F6-E4?

Yes. When the float trips, the dishwasher runs the drain pump as a safety response and refuses to fill.

Can tilting the dishwasher reset the float?

Some people tilt the unit to drain the base pan, but that only clears the symptom. Find and fix the leak or the float will trip again.

Why would leveling cause this?

The float is a small mechanical switch. If the whole tub tilts, the float can ride high enough to trip even with a normal water level.
