Samsung Dishwasher Throwing a 9E Error?

Your Samsung dishwasher is flashing a 9E error and either drowning itself in water or sitting there bone dry, refusing to start a cycle. Either way, your dishes aren't getting clean and your kitchen floor might be getting a surprise bath.

What's Actually Going On

The 9E error code on a Samsung dishwasher is the machine's way of telling you it's lost its mind about water, specifically, it can't figure out how much water is actually inside the tub. That's the Samsung water level sensor doing a bad job, or more accurately, failing to do its job at all. The sensor monitors water pressure at the bottom of the machine and sends that info to the control board so the dishwasher knows when to stop filling. When the sensor goes bad, the board is flying blind.

Here's where it gets annoying: a failing Samsung dishwasher water sensor doesn't always fail the same way. Sometimes the tub overfills because the sensor never signals "full," and water creeps up past the door seal. Other times the machine won't fill at all because the sensor is sending a false "full" reading right from jump, so the control board thinks it's already got enough water before a single drop comes in. Both situations throw that 9E error, and both situations land you at the same part.

Before you assume it's the sensor, quick sanity check: make sure the drain hose isn't kinked, run a reset by cutting power for five minutes, and look for anything obviously clogged around the sump area. If the 9E error comes right back and you're still seeing overfill or no-fill behavior, the sensor is almost certainly your culprit. The control board is rarely the issue when the symptom is this specific.

The Fix

The part you need is the DD81-01428A water level sensor. Here's how to get it swapped out:

Kill the power and water supply. Seriously, don't skip this. Unplug the dishwasher or flip the breaker, and shut off the supply valve under the sink.
Pull the dishwasher out from under the counter if needed, you'll want access to the bottom of the unit. Lay down a towel because there's gonna be some residual water.
Remove the lower spray arm and the sump cover inside the tub. These usually pop off or have one or two screws holding them in place.
Locate the water level sensor, it's typically mounted near the sump/float area at the base of the tub, connected by a wire harness.
Disconnect the harness, unclip or unscrew the old sensor, and pull it out.
Snap the new DD81-01428A in, reconnect the harness, and reverse your steps.
Run a short test cycle and watch for that 9E error. Spoiler: it shouldn't come back.

The whole job usually takes 30-45 minutes if you're reasonably handy. No special tools required beyond a basic screwdriver set.
