E1 F9 on a Maytag dishwasher is functionally identical to F9 E1 , both mean drain timeout. The reversed display order is a firmware difference across Maytag DTM platform model generations. The diagnostic steps, parts, and fixes are exactly the same as F9 E1.
When I see this code on a Maytag, I immediately look for standing water. It means the control board expected the tub to be empty but the pressure sensor or float says otherwise. Usually it's a simple blockage, but on MDB8959 models, a worn spray arm hub actually sags down and chokes off the suction. If the pump's humming but not moving water, you've got a physical clog.

What Does the E1 F9 Code Mean?
Think of this as a lazy drain warning. Your Maytag tried to kick the water out for several minutes and eventually gave up to prevent the pump from overheating. Before you buy parts, listen for a grinding noise. I often find cherry pits or glass stuck in the impeller, which mimics a pump failure but costs nothing to fix. Most of the time this code is a $0 fix.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:
Spray arm bearing hub worn, arm drooping and partially blocking filter inlet (MDB8959)40%
Clogged drain filter24%
Drain pump failure22%
Kinked or blocked drain hose14%
Symptoms You May Notice
Standing water at the bottom of the tub after the cycle ends, sometimes a full inch of murky gray water just sitting there.
E1 F9 shows up on the display at the end of the drain cycle, or sometimes mid-cycle if the water can't drain fast enough.
You can hear the pump humming or buzzing but the water level isn't going anywhere.
The wash cycle stops and won't finish, dishes come out wet and sometimes still dirty.
A faint sour or musty smell from water sitting in the tub between cycles.
Can you reset a Maytag dishwasher to clear the E1 F9 code?
Press and hold the Cancel or Drain button for three seconds to force a pump-out cycle. If the water clears, the code resets on its own. If the tub's still full, bail the water out manually before pulling the filters or you'll end up with a kitchen floor covered in gray water. After you've fixed the actual cause, run a short cycle to confirm the drain completes fully.

Frequently Asked Questions
What's the difference between Maytag E1 F9 and F9 E1?
In the field, these codes are identical. Maytag just flipped the characters in their software during a specific production run. Whether your screen says E1 F9 or F9 E1, the logic is the same: the control board timed out the drain cycle because the water level didn't drop fast enough. I treat them exactly the same way on a service call. Start with the filters and the drain hose before assuming the pump is dead, because most of the time it's just a physical blockage and you don't need any parts at all.
Can I still use my dishwasher when it shows E1 F9?
Honestly, no. Well, you can try, but it's going to keep stopping mid-cycle and leaving standing water in the tub. And if you keep running it with water pooling and a struggling pump, you risk burning out the motor. The pump's designed to move water, not spin in sludge. Fix the blockage first. It takes maybe 20 minutes to clean the filter and check the drain hose, and that solves it probably 60% of the time. Don't keep forcing it through cycles hoping it'll clear itself. It won't.
How much does it cost to fix the E1 F9 error?
Depends entirely on the cause. Clogged filter? Zero dollars and fifteen minutes of your time. Kinked drain hose? Also free. A new drain pump runs about $40-$60 for the part (WPW10348269) and it's easy enough to swap yourself if you're comfortable with basic tools. The MDB8959 spray arm hub assembly is around $25-$35 online. If you're calling a tech out, budget $150-$250 all in for a pump replacement including labor. Start with the free stuff first, then decide if you actually need parts.
How do I tell if it's the pump or just a clog?
Listen when the dishwasher tries to drain. If you hear a hum or buzz and nothing's happening, that's usually the pump running into a physical obstruction, something jammed in the impeller or a kinked hose downstream. If you hear absolutely nothing during the drain cycle, the pump might not be getting power or the motor's seized. Grinding noise? That's debris in the impeller for sure. Pull the filter and feel around in the sump before you order anything. Nine times out of ten there's something physical down there.
How long does replacing the drain pump take?
If you've done it before, about 45 minutes. First time, budget 90. You might need to pull the unit out slightly to access the pump from underneath depending on the model year. Disconnect the water supply, disconnect the drain hose, and put towels down because water will drip. The pump either unclips or has two screws depending on the year. Take a photo of the wire connections before you disconnect anything, seriously, it saves a ton of frustration. The job's rated beginner difficulty, just take your time.
Does cleaning the filter always fix this?
Not always, but way more often than people expect. I'd say on roughly half the E1 F9 calls I go on, the filter's just packed with grease and food debris, especially when nobody's cleaned it in six months or more. Maytag says monthly, basically nobody does that. So start there. If you've cleaned the filter and water still isn't draining, check the drain hose for kinks next, then the air gap or disposal connection if you have one, then finally pull out the multimeter and test the pump.
