Samsung Dishwasher Error Code DE — Door Won't Latch

What Does This Error Mean?

The DE error means your Samsung dishwasher thinks the door is open — even if you've pushed it shut. The dishwasher won't run unless the door is fully latched and locked. This is a safety feature to prevent water spraying everywhere. DE usually means the door latch, the door switch, or the wiring connecting them has a problem. Most cases can be fixed without a technician.

Common Causes

Door latch mechanism is worn out or broken and not clicking into place firmly
Door latch strike plate on the tub is bent or misaligned so the latch can't engage
Door switch (microswitch inside the latch assembly) has failed and isn't sending the 'closed' signal
Wiring harness from the door to the control board is damaged or has a loose connection
Dishwasher is not level — a tilted machine causes the door to hang crooked and not seat properly

How to Fix It

Open the door fully and push it firmly shut — don't just push until you hear a click, apply steady pressure to make sure it seats completely. Try pushing at the corners and edges, not just the center. A door that appears closed can still be slightly ajar.

Some Samsung dishwashers require a firm, deliberate push to engage the latch — a gentle push isn't always enough.
Check if the dishwasher is level. Use a spirit level on the top edge of the open door. If the machine is tilted left, right, or forward, adjust the leveling feet underneath. An uneven dishwasher puts stress on the door and can prevent proper latching.

Leveling feet are usually adjustable by hand or with pliers. Turn clockwise to lower, counter-clockwise to raise.
Inspect the door latch and strike plate (the slot on the tub rim that the latch hooks into). Look for visible cracks in the latch plastic, and check whether the metal strike plate is bent or pulled away from the tub wall. A bent strike plate can be carefully bent back into position.

Replacement door latch assemblies for Samsung dishwashers are available on Amazon and appliance parts sites for $20-$50.
Check the door gasket (rubber seal around the door). If the gasket has slipped out of its channel or has a bulge, it can prevent the door from fully closing. Push the gasket back into its groove around the entire perimeter.

Dish soap residue can cause the gasket to stiffen and bulge over time. Wipe it clean with a damp cloth.
If the latch clicks and feels secure but the DE code still shows, the door switch has likely failed. This is the tiny microswitch inside the latch assembly that tells the control board the door is shut. A technician can test and replace it — or you can replace the entire latch assembly as a unit.

Search for your model number plus 'door latch assembly' on appliance parts sites to find the correct replacement part.

When to Call a Professional

If you've checked alignment and the latch still doesn't click firmly, the latch assembly or door switch likely needs replacement. These parts are relatively affordable ($20-$60 for the part). A technician can diagnose and replace the latch assembly in about an hour. Expect $100-$200 for parts and labor.

Frequently Asked Questions

Why does the DE error appear mid-cycle?

If DE appears while the dishwasher is already running, the door latch came undone during the cycle. This can happen if the latch mechanism is worn and can't hold against vibration. It's also worth checking whether anyone bumped the door or opened it accidentally. A worn latch that holds at the start of a cycle may work loose once the motor creates vibration.

Can I run the dishwasher with tape holding the door shut?

No — please don't do this. The dishwasher builds up pressure and heat during a cycle. The door latch is a safety mechanism. Running it with an improvised fix is a water damage risk. Fix the latch properly before running another cycle.

Is DE the same as the dishwasher beeping with no error code?

Not necessarily. A DE error should show on the display. If the dishwasher beeps and won't start with no code, the door may simply not be closed far enough to trigger the door switch — try pushing the door harder. If a code appears, DE specifically means the door sensor is reporting an open door.
