Maytag F0 E3 Error: Pressure Switch Malfunction

Quick Answer

Maytag F0 E3 is a pressure switch malfunction. The pressure switch reads water level via a small air hose connected to the outer tub. Start by finding the hose (it is a thin rubber tube that runs from the switch near the top of the cabinet down to the tub) and checking it for kinks or cracks. Blow gently into the disconnected hose end - the switch should click.

Nine times out of ten when I show up for this code, it's the air trap clogged with detergent buildup. Takes maybe 20 minutes to clean. But here's what you really need to know: this code means your washer can't tell how full it is. That's not a 'run it one more time and see' situation. That's a potential flood waiting to happen. Get it fixed before you touch that start button again.

What Does the F0 E3 Code Mean?

OK so F0 E3 basically means the control board is getting garbage data from the pressure sensor system and can't figure out how much water is in the tub. I've cleared this code on a ton of Maytag washers, especially ones that are 3-6 years old and have been run on heavy detergent doses. The whole repair is usually under $30 in parts and takes about an hour if you're reasonably handy.

Symptoms You May Notice

  • The display shows F0 E3 and the machine stops dead, usually right in the middle of the fill phase before it's even gotten close to the right water level.
  • Washer fills way past where it should and you can hear water sloshing around more than usual when it tries to agitate, or on front loaders you can actually see water sitting above the door gasket.
  • Machine keeps trying to drain and then refill in a loop, never actually starting the wash cycle, because it can't get a stable water level reading it trusts.
  • Water level in the tub looks noticeably different from load to load even when you're running the exact same cycle setting every time.
  • You can hear the washer humming during fill but it just sits there way longer than it should, like it doesn't know when to stop.

Can you reset a Maytag washer to clear the F0 E3 code?

After fixing whatever caused the code, unplug the washer from the wall and leave it unplugged for at least 60 seconds. This clears the stored fault from the control board's memory. Plug it back in, select a short cycle like Rinse and Spin, and watch the fill phase for the first minute. You want to see it fill, stop at the right level, and move into the wash phase. If it does all that, you're good.

Frequently Asked Questions

What is the air trap on a Maytag washer?
The air trap, sometimes called the air dome, is a small dome-shaped plastic fitting attached to the outer tub. It captures an air pocket that gets compressed as water rises in the tub. That compressed air pushes through the pressure hose to the pressure switch, which translates that pressure into a water level reading the control board can use. When the air trap clogs with detergent residue, the air pocket can't form correctly and the pressure readings become unreliable. Cleaning it is usually the fix for F0 E3 when the hose itself looks fine.
Is F0 E3 dangerous?
Yeah, it's not one to ignore. F0 E3 means the washer may not be able to detect when the tub is full, which creates a real risk of overfilling. That can mean water spilling out of the tub and onto your laundry room floor. Stop using the washer until the pressure system is repaired. The good news is most of the time the fix is a $0 cleaning job, not a big expensive repair.
Can I use my washer with F0 E3?
Don't do it. Without reliable water level sensing, the washer can overfill and you'll end up with water all over the floor. I know it's tempting to just run one more load, but the repair is usually quick and cheap. Start with the pressure hose and air trap cleaning before you assume anything expensive has failed. Ninety percent of the time that's all it is.
How much does it cost to fix F0 E3?
Depends on what's causing it. If it's a clogged air trap, you're looking at zero parts cost and maybe 30 minutes of your time. A replacement pressure hose is $5-10. A new pressure switch runs $15-25 for the part. The expensive scenario is a control board, which can be $150-300. But honestly I've cleared this code with nothing but a small brush and warm water more times than I can count. Start with the free fix first.
How do I find the pressure switch on my Maytag washer?
On front-load Maytag washers, it's usually mounted near the top left or right corner of the cabinet, behind the top panel. It's a small round component, maybe the size of a poker chip, with a rubber hose port on one side and a wire connector plugged in. To access it, remove the two screws at the rear edge of the top panel and slide it forward. On top-load Maytags it's also under the main top, same deal with the two screws at the back. Once you're in there it's usually pretty obvious, just follow the small rubber hose and it'll lead you right to it.
