Maytag Dishwasher F6 E4 — What It Means & How to Fix It
Also shown as F6E4, 6-4 on some models.
The anti-flood float in the bottom of your Maytag — the mechanical backstop that halts filling if water climbs too high — is sending an open signal, most often because it's physically stuck rather than because the tub is actually flooding.
What this code means
F6 E4 (6-4 flashed) reports the overfill float switch reading open. That float is a small dome on the tub floor that rises with the water and trips a safety switch to cut the fill; when the control can no longer trust its signal, it raises this code. A float jammed by a stray utensil or hardened detergent is the usual, harmless cause — but a float that keeps tripping because water seeps in while the machine is off points back at an inlet valve that isn't sealing.
Some owners see this alongside water pooling in the base; if there's standing water you didn't add, treat it as a possible leak and stop running cycles until you've traced the source.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Float physically stuck high on debris or a fallen utensil | Very common | Yes — free by hand |
| Float switch beneath the float failed | Occasional | No — technician job |
| Inlet valve seeping water in while off, raising the float | Occasional | Partly — observe |
| Wiring fault to the float switch | Less common | No — technician job |
What you can try yourself
- Open the door and find the float — a small plastic cap near the front of the tub floor — and lift it; it should rise and drop with a light click and nothing holding it.
- Clear anything around it: a dropped piece of cutlery, a chip of food, or hardened detergent can all pin it up.
- Wipe the float and its well clean, then seat it and check the free movement again.
- Switch off at the breaker for two minutes to reset, then run a short cycle and watch whether the code clears.
- If the float moves freely but 6-4 returns — or you keep finding water in the tub between washes — the float switch or a seeping inlet valve needs a technician.

When to call a technician
- The float moves freely yet F6 E4 keeps coming back.
- Water reappears in the tub base when the machine has been sitting idle.
- Visible water escaping onto the floor, which is a leak rather than a stuck float.
Typical professional repair cost: Float switch or related repair generally runs $130–$250 with labour.
Frequently asked questions
Where is the float on a Maytag dishwasher?
It's the small plastic dome sitting on the floor of the tub, usually toward the front. It rises as the tub fills and trips a switch underneath to stop the water. You can lift it with a fingertip to check it moves freely.
My float moves fine but F6 E4 won't clear — now what?
If the float itself is free, the switch beneath it or its wiring is the likely fault, and that's a technician check. Also watch for water arriving in the tub while the machine is off, which would mean the inlet valve isn't sealing.
Is F6 E4 a leak?
Not by itself — it's the overfill float reading open, often just because it's stuck. But if you see standing water you didn't add, treat it as a possible leak and stop running cycles until the source is found.

- Maytag Dishwasher F1 E1 Your Maytag's control board has flagged one of its own relays as stuck on — an output that should have switched off still reads live — and a full power-down often clears a false alarm, while a genuinely welded relay means board-level service.
- Maytag Dryer PF PF on a Maytag dryer is the power-failure notice: the dryer lost power mid-cycle and stopped. Nothing is broken — clear the code and resume the load.
- Maytag Washer F8 E1 Your Maytag washer started filling but isn't sensing enough water arriving — nearly always a supply-side issue with the taps, hoses, or inlet screens rather than a fault inside the machine.
- Maytag Washer F9 E1 Your Maytag washer is taking too long to pump out — the machine flags F9 E1 when the water hasn't cleared within about eight minutes, usually because something is blocking the drain path.
