Common Dishwasher Error Codes (All Brands)

Common Dishwasher Error Codes Explained (All Major Brands)

Modern dishwashers aren’t just metal boxes that spray hot water, they’re smart enough to let you know when something’s wrong. Nowadays, nearly all mid- to high-end models, including dishwasher with garbage disposal, flash error codes when a part fails, something leaks, or water isn’t doing what it’s supposed to.

These codes are your machine’s way of saying, “Hey, something’s off and here’s a clue.” They can be a little cryptic, sure, but they save you time by pointing to the exact system that needs attention. No more guessing or blindly ordering parts.

Each brand likes to speak its own language when it comes to error codes, but many follow similar logic: a water fill problem here, a drain issue there, maybe a leak sensor tripped. This article breaks down common codes by brand and gives you straight answers on what they mean and what to do next.

Why Dishwashers Show Error Codes

Dishwashers are smarter than they used to be. When something’s off water’s not flowing right, a sensor trips, or a pump jams up the machine flashes a code. That code is basically its version of saying, “Hey, something’s wrong, and here’s a clue.”

The point is early detection. You don’t want to wait until the kitchen floor is a lake or the dishes come out with last night’s lasagna still caked on. Error codes give you (or a repair tech) a starting point to find the problem fast. That saves time, and usually money.

Instead of spending an hour poking around, the code points you toward the issue water inlet, drain line, electrical glitch, whatever. It’s not magic, but it’s way better than guessing. And while not every code means a huge problem, all of them are meant to stop something worse from happening.

Error Codes by Brand

Bosch

• E15: Water leakage detected the dishwasher’s built-in leak protection has kicked in. Usually caused by over-sudsing, a cracked hose, or a spill inside the base.
• E25: Drain pump is blocked. Could be food scraps, glass shards, or buildup. Check the filter and impeller.
• E09: Water isn’t heating properly likely a busted heating element. You’ll need a multimeter or a technician.

Whirlpool

• F2E2: Communication problem between user interface and control board. Maybe a loose wire, or the control board’s gone haywire.
• F6E4: Float switch stuck could mean water at the bottom of the tub or a tilted dishwasher. Check level and look for leaks.
• F8E1: Low water flow. This one’s often your valve under the sink not being fully open, or a clogged inlet screen.

GE (General Electric)

• C1: Drain pump’s working overtime. Usually a clog in the drain hose, filter, or air gap. Time to inspect the plumbing.
• C2: Dishwasher isn’t draining. Can be a similar cause to C1, or maybe the drain solenoid’s stuck.
• C3: Leak detected float switch has tripped. Pull the unit out and check the bottom pan for water.

Samsung

• LC or LE: Leak sensor tripped often soap suds or a minor drip sets this off. Wipe things down, dry the pan, and try again.
• 4E: Water supply problem. Valve closed? Kinked hose? Filter gummed up? Start there.
• HE: Heater error. Could be a failed element or wiring issue. Not DIY unless you’re handy with a multimeter.

LG

• AE: Water leak. Often door seal or hose is the culprit. Look under and around the machine.
• FE: Too much water in the tub. This usually means a faulty water inlet valve stuck open.
• IE: Inlet error – not filling properly. Could be low water pressure or a clogged inlet filter.

Maytag

• F9E1: Draining slow or not at all. Check drain hose, filter, and garbage disposal connection.
• F6E6: Control board miscommunication. Sometimes a hard reset (breaker off, wait, power on) buys you time.
• F5E1: Door not closing right. Inspect latch and make sure racks aren’t sticking out.

KitchenAid

• (Same codes as Whirlpool, mostly same parent company.)
• F8E4: Water pooled in the bottom float tray got wet. Could be a leak, or you overfilled with soap.
• F5E2: Door latch issue. Try gently adjusting the door alignment. If you have to slam it, you’ve got a problem.

Each brand speaks its own language, but most codes boil down to five things: water getting in, water getting out, heat, leaks, or electronics not syncing. Learn what’s normal for your machine or keep this list bookmarked.

What to Do When You See an Error Code

First, don’t panic. Error codes seem intimidating, but they’re basically the dishwasher’s way of raising its hand and saying, “Hey, something’s off.” Here’s how to handle that signal without diving straight into repair mode.

1. Crack open the user manual.

Each brand and sometimes even each model uses slightly different codes. Your manual will tell you exactly what your dishwasher is trying to say. No manual lying around? A quick search for your model number + “error codes” will usually do the trick.

2. Try a good ol’ reset.

This isn’t magic, it’s just your dishwasher getting a fresh start. Cut power at the breaker or unplug the unit for about 5 minutes. Some models also have a reset combo on the buttons (like “Start” + “Cancel”). If the code clears, great. If it comes back, keep reading.

3. Inspect the obvious stuff.

Take a minute to poke around:

• Is the door closing all the way?
• Is water flowing to the machine?
• Are you seeing a puddle underneath (leak sensor trip)?
• Check the drain area and filters, food gunk builds up fast.

4. Don’t keep running it if the code sticks.

If the reset doesn’t help and the problem isn’t obvious, don’t force a cycle. Some codes mean water is leaking, the heater’s not working, or sensors are fried, forcing the machine to ru, whichn could make it worse.

5. Call in backup if needed.

There’s a line between smart DIY and unnecessary damage. If the code keeps coming back or involves core parts (like the motor or control board), it’s probably time to get a repair tech involved.

Resetting the Dishwasher

Resetting a dishwasher is often the closest thing to a magic fix. It won’t solve a broken pump or a cracked hose, but it can clear up a glitchy board or a one-off sensor hiccup.

Most dishwashers have a reset combo pressing and holding certain buttons like “Start” and “Cancel” at the same time. Sometimes it’s “Heated Dry” and “Normal” cycled a few times. Depends on the brand. And yes, your manual will tell you the exact method, but let’s be real you probably threw that out or stuffed it in a drawer years ago.

If buttons don’t do the trick, go old-school: flip the breaker. Turn off the dishwasher’s power at the panel for 5 -10 minutes. That forces a full power cycle and can flush out software bugs. Just make sure no one’s in the middle of making toast while you kill half the kitchen circuit.

Once power comes back on, the system should reboot clean and hopefully without the error code. If it reappears right away, that’s your sign it’s not just a glitch. Time to dig deeper or call in a pro.

When It’s a Simple Fix

Not every error code is a sign of major failure. Sometimes it’s just a nudge your dishwasher saying, “Hey, fix this little thing and we’re good.” Here are the usual suspects when things go sideways but don’t require a toolbox or technician.

• Loose door latch: If the door isn’t clicked in place, many dishwashers won’t even start, and you’ll get a mysterious error code. Open it, close it with intent. If it clicks, good. If it doesn’t, inspect for food scraps or worn hinges.
• Blocked filter or drain hose: A quick buildup of gunk in the filter or a bent/kinked drain hose can trigger drainage errors. Pull the bottom rack out, twist and lift the filter, rinse under the tap. For the hose, make sure it isn’t pinched if you recently pushed the dishwasher back in place.
• Water valve turned off: Maybe someone did plumbing work and forgot to turn the water back on. Or maybe the dog bumped it (yes, really). Check under the sink the valve should be fully open. Water supply errors are common and often this simple.
• Too much soap or the wrong kind: Dishwasher bubbles aren’t cute they wreak havoc. If you used regular dish soap instead of dishwasher detergent, you might get a flood and an overflow code. Rinse and run a cycle with no soap to defoam.

Bottom line: Before calling anyone, check the basics. Half of all error codes are just your dishwasher asking for a little attention not a total breakdown.

Keeping Errors From Coming Back

Getting rid of an error code is good. Not having it come back is better. Here’s what matters:

1. Clean the Filter and Spray Arms Regularly

Frequency: Every couple of weeks

Why it matters: Gunk builds up quickly especially if you don’t rinse dishes well (no judgment).

Risks: A clogged filter can choke the system, leading to errors like:

• Poor drainage
• Weak spray performance

2. Use the Right Detergent And the Right Amount

Avoid over-soaping: More isn’t better. Excess suds trip:

• Overflow sensors
• Leak detectors

What to use:

• Dishwasher-specific products only
• Avoid hand soap and non-compatible cleaners

Tip: Don’t pack the soap cup like you’re sealing a time capsule.

3. Load Smart, Not Just Full

Tempting but risky: Overloading blocks spray arms.

Consequences:

• Poor performance
• Low water pressure detection
• Error codes

Best practice: Leave enough room for spray arms on both top and bottom to spin freely.

4. Check Seals and Hoses Occasionally

What to look for:

• Cracks
• Mold
• Signs of slow leaks

Why it’s important: Even tiny drips can confuse your dishwasher into thinking there’s a full-blown leak.

Think of it like: Changing your oil not thrilling, but very necessary..

Summary

Dishwasher error codes might look intimidating, but they’re usually just the machine’s way of pointing at what’s wrong. A leaky hose, a jammed drain, or even a loose door latch can spark a warning. Most of the time, a quick inspection and a basic reset is all it takes.
