Maytag Dishwasher FA E4 Error Code: Diagnosis and Fix

Quick Answer

Maytag Dishwasher FA E4: The FA E4 error code on Maytag dishwashers indicates a flood protection (FA) fault with a specific sub-code (E4) pointing to the anti-flood sensor detecting water in the base pan. On Maytag Quiet Series models, FA is the flood alert system - when water accumulates in the machine's bottom base pan (below the tub), a float or sensor triggers FA to prevent water from reaching the floor. E4 specifically identifies that the anti-flood sensor registered water where it should n

This code's usually a slow burner. It doesn't mean your kitchen's about to flood, but it does mean the safety tray underneath the tub is holding water. Most of the time I find a tiny pinhole in the door gasket or a loose hose clamp that's been dripping for weeks without anyone noticing. If you clear the water and it's back in three days, you're definitely looking at an active leak rather than a one-time splash.

What Does the FA E4 Code Mean?

When I see FA E4 on a Maytag, the first thing I do is pull the kickplate. This is rarely a software glitch. There's physical water touching a sensor in the plastic pan at the very bottom of the machine. It's a protective hard stop designed to save your hardwood floors from a way bigger repair bill. I've seen this on probably a dozen Maytag dishwashers in the past year alone, and honestly, most of them were just a bad door gasket.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Door gasket leak at bottom corners (most common on Maytag Quiet Series)40%

Drain hose connection leak at tub or pump outlet24%

Circulation pump seal failure causing internal drip14%

Tub weld or sump seal failure12%

Water inlet valve dripping after valve closes10%

Symptoms You May Notice

FA E4 flashing on the control panel mid-cycle with the machine stopped dead and pumping itself out
A thin film of water on your kitchen floor near the front edge of the dishwasher that wasn't there when you loaded it
Machine kicks on fine but kills itself 10 to 15 minutes into the wash cycle, every single time
Door gasket feels stiff and crumbly, or you can see cracking right where the rubber curves around the bottom corners
Standing water in the plastic base tray when you pull the kickplate off

Can you reset a Maytag dishwasher to clear the FA E4 code?

You can't reset FA E4 with a button combo alone. The sensor is a physical switch that has to be completely dry first. Kill the breaker, pull the kickplate, and soak up all the standing water. Point a fan or hair dryer at the base pan for about 20 minutes. Flip the breaker back on and wait 30 seconds. If the pan's truly dry, the display should clear on its own. If it doesn't, the float switch might be stuck in the raised position and needs a gentle push back down to reset.

Frequently Asked Questions

What causes the Maytag FA E4 error code?

Think of FA E4 as a catch-all for any water that escaped the tub. In the field, I find it's rarely a burst pipe or some dramatic failure. It's usually a door gasket that's lost its shape over the years or a buildup of gunk in the bottom corners of the door that's preventing a tight seal. Occasionally, using too much detergent causes suds to push over the front lip of the tub, which drains directly into that bottom tray and trips the sensor.

How do I drain the base pan to clear the FA E4 code on my Maytag dishwasher?

You've gotta get the kickplate panel at floor level off first. Once that's out of the way, you'll see the plastic drip tray. I use old towels or a small wet-vac to get every drop out. The trick most people miss is drying the sensor itself. It's a small plastic housing with a couple wires attached to it. If that thing stays damp, the code stays on. Give it a good wipe down and point a fan at it for a bit before you try to restart.

Can I run my Maytag dishwasher with the FA E4 code showing?

I wouldn't. The machine's actually trying to protect you here. If you keep resetting it without fixing the leak, that water can eventually reach the control board or the main wash motor. That turns a $30 gasket fix into a total loss. Plus, if that tray fills up and overflows, your subfloor's the next casualty. Find the leak source and fix it before you run another load. It's not worth it.

How much does it cost to fix the FA E4 error code on a Maytag dishwasher?

Depends on what's leaking. If it's just the door gasket, the part number is W10900014 and it runs about $25 to $40 online. Add maybe an hour of your own time and you're done. If it's the circulation pump seal, expect $80 to $150 on the pump assembly plus a couple hours of work. If you're calling a tech, budget $150 to $250 all-in for a gasket swap, and more like $300 to $400 if the pump's involved. I had a guy last month pay $340 for a service call that ended up being a $30 gasket and 45 minutes of work.

How do I know if the FA float switch itself is the problem?

After you've dried out the base pan completely and FA E4 still won't clear, the float switch is probably stuck. It's a small plastic float in the base tray that sits low when dry and rises when water pushes it up. If it's stuck in the up position even with a dry pan, it'll keep triggering the fault. Reach in and gently push it down. If it springs back up on its own with no water present, replace it. Part runs about $15 to $25 and it's a quick swap.
