Fix Samsung DW80CG5451SR AutoRelease Door

I’m Drew Callahan, and after covering over 80,000 miles across North America in three different rigs, I’ve tackled my fair share of appliance repairs, including the Samsung DW80CG5451SR. The AutoRelease door issue is one of the more common problems I encounter with this model. In most cases, the root cause is a malfunctioning door latch actuator or a faulty wax motor responsible for the auto-open mechanism at the end of the cycle.

🔨 Pro Tip from Drew

Before you replace the wax motor (part DD94-01006A), check the door hinge springs first. A weakened spring can prevent the door from popping open even when the actuator works properly. I’ve seen many folks replace the wax motor only to find the door still won’t release because they overlooked the hinge tension. Always test the actuator with a multimeter for continuity before ordering parts.

Common Symptoms & Causes

If you’re having issues with your Samsung DW80CG5451SR, these symptoms can indicate an AutoRelease door malfunction.

The dishwasher door fails to pop open automatically at the end of the drying cycle
The door opens too forcefully or swings fully open instead of releasing slightly ajar
Steam and moisture remain trapped inside after the cycle completes, leaving dishes wet
The AutoRelease feature works intermittently, triggering on some cycles but not others

These problems typically result from a faulty door latch solenoid, a worn AutoRelease spring mechanism, or a control board signal that isn’t functioning correctly.

Safety First

Unplug the dishwasher from the power outlet before starting any repair — never work on a live appliance.
Shut off the water supply valve before disconnecting any water lines or hoses.
Wear work gloves when handling metal brackets, sheet metal edges, or sharp components.
Take photos with your phone before disconnecting any wiring harnesses or connectors.
Work in a well-lit area with enough floor space to lay removed panels flat.

Step-by-Step Repair Instructions

Step 1

First things first, disconnect the dishwasher from power at the circuit breaker or by unplugging it. Working on a live appliance can lead to serious injuries. The Samsung AutoRelease system is designed to pop the door open 1–2 inches at the end of a cycle. If the door slams open or fails to open at all, that auto-release mechanism is where I start my diagnosis. Identifying whether it slams or won’t open at all will guide you on which part of the repair to focus on.

Step 2

Next, remove the four T20 Torx screws along the sides of the inner door panel. This gives you access to the components behind the latch area, where the auto-release motor and solenoid assembly are located. This assembly is responsible for physically pushing the door latch open on command, so any fault here will directly lead to either a violent release or no release at all. Pro tip: snap a photo of the wiring and spring positions before you disturb anything to make reassembly easier.

Step 3

Now it’s time to check the motor solenoid. Set your multimeter to resistance mode and probe the motor solenoid terminals. A healthy solenoid should read between 100–300Ω, confirming that the coil is intact and can generate the magnetic force needed to trigger the door release. An open reading (OL) means the coil is broken; near zero ohms indicates a short circuit. Either way, the solenoid will need replacement. Don’t skip this test, even if the part looks undamaged, as coil failures aren’t always visible.

Step 4

If the door is slamming open, it’s likely that the release spring is over-tensioned, storing too much energy and snapping the door open with excessive force. To reduce tension, simply relocate the spring to the next hook position. This lowers the stored energy without removing the spring entirely, which would prevent the door from opening at all. Make this adjustment incrementally and test between each change, as the correct tension can vary slightly by installation.

Step 5

If the door never opens at the end of a cycle despite the solenoid testing good, ensure that the AutoRelease feature is actually enabled. This can be toggled off in the settings. Navigate to the Door Open Setting through either the Samsung SmartThings app or the dishwasher’s control panel to confirm it’s active. This is a commonly overlooked software setting that can mimic a hardware failure and waste valuable repair time.

Step 6

Finally, restore power and run a short wash cycle to verify the repair. Watch for the door to crack open gently by 1–2 inches about two minutes after the cycle completes. A smooth, controlled opening confirms that both the solenoid actuation and spring tension are correct. If there’s still slamming or failure to open, revisit the spring adjustment or solenoid replacement from earlier steps. Pro tip: stay nearby during this test cycle so you can directly observe the door release moment.

Where to Buy Replacement Parts

When to Call a Professional

If the issue continues after following all these steps, the problem might involve a failed main control board, a seized circulation or drain pump, or wiring that requires specialized diagnostic tools. In that case, it’s best to contact a licensed appliance technician. And remember to shut off the water supply valve before any work that opens the fill or drain circuit.

How Much Does This Repair Cost?

DIY parts for fixing an AutoRelease door issue on the Samsung DW80CG5451SR typically run $10–$60, depending on what you need. A professional service call for the same repair usually costs $150–$300 once labor and fees are included. Tackling this repair yourself can save you $100 or more.

Frequently Asked Questions

Why is my Samsung DW80CG5451SR door not opening automatically after a cycle?

The AutoRelease mechanism could have a faulty door latch motor or a blocked release vent. Check for obstructions around the door seal and ensure the dishwasher completes its full drying cycle before diving deeper into diagnostics.

Can I disable the AutoRelease feature if it keeps malfunctioning?

Absolutely! You can typically turn off AutoRelease through the control panel settings menu. Check your user manual under “Dry Options” to find the toggle for this feature.

Is this AutoRelease repair something I can safely do myself?

Basic fixes like clearing obstructions or resetting settings are safe for most homeowners. However, replacing the door latch motor or wiring components should be handled by a certified appliance technician.

The Wax Motor That Controls AutoRelease on the DW80CG5451SR

If the door isn’t popping open at the end of the cycle, the thermal wax motor is your first suspect—this is the component that actually triggers the latch to release when the cycle finishes. Most of the AutoRelease failures I’ve diagnosed on this Samsung model come down to a failed wax motor that’s simply lost its ability to expand and activate the mechanism.

What works

Direct replacement—this DD66-00089A motor is the exact part Samsung spec’d for this model, so no guessing on compatibility or fitment.
You’ll see the door actually release on the next cycle, which is how you confirm the diagnosis was right (beats ordering a latch only to find out the motor was the problem).
Wax motors are one of the more reliable fixes on this model—I’ve rarely seen a replacement motor fail again unless there’s an underlying control board issue.

What doesn’t

You have to be certain the motor is actually the culprit before ordering—if the problem is a faulty latch or a control board that’s not sending the release signal, this motor won’t fix it.
The installation isn’t complicated, but the motor sits in a spot where you need steady hands and decent lighting to disconnect the old one without damaging the connector.

I’ve had customers order the door latch first when the real issue was the wax motor—then they’d call back frustrated after replacing the latch with no result. Test the motor’s responsiveness with a multimeter before you order parts, or at minimum confirm the control board is sending power to the motor at cycle end.
