Quick answer
The Blomberg DWT51600FBI uses a condensation drying system, so warm vapor at the top during or after a cycle is not by itself proof that the door seal has failed. Blomberg's official FAQ says to open the door slightly so steam can escape, and it separately says the dishwasher door must close properly. First determine whether the report is vapor, a few droplets, or a stream of water; then check the door closure, gasket, rack or dish interference, and visible leakage without removing panels or adjusting the latch. If water reaches the floor, the door will not latch, or the symptom continues after the external checks, stop the cycle and use the model-specific service path.

Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Run or observe the next affected cycle only while you can monitor it safely, and record whether the top symptom is vapor, isolated droplets, or liquid running onto the floor. Note when it appears—during washing, at the end of the cycle, or only after the door is opened—and whether the dishes are merely warm or the door area is wet.
Expected result: Only warm vapor appears, a few droplets form at the top, water runs down the cabinet or onto the floor, or the symptom occurs before the cycle is complete.
Next step: If there is a puddle, stop the cycle, protect the floor, and do not run another cycle until the external checks and model-specific service decision are made. If there is vapor only, continue with the closure and gasket checks.
Why this matters
Why: The DWT51600FBI's listed condensation drying system makes vapor plausible. A liquid trail or puddle indicates a closure, loading, installation, or leak condition that cannot be dismissed as normal drying.
-
Check 2
With the dishwasher off and cool enough to touch, inspect the full door gasket and the top edge of the tub. Wipe visible food residue or debris with a damp cloth, then check that the gasket is seated and not folded, cut, pulled out, or trapped by a rack or dish.
Expected result: The gasket is dirty, displaced, damaged, or obstructed; the rack or dish touches the door; or the gasket and door edge look clear.
Next step: Remove only the visible obstruction and clean the gasket. Do not stretch, glue, heat, or replace the gasket without confirming the exact DWT51600FBI part and instructions; arrange service for damage or persistent liquid leakage.
Why this matters
Why: Blomberg identifies a clean gasket as a maintenance requirement, and a physical obstruction can prevent a proper door closure or redirect steam. A clear gasket does not prove that the latch or installation is correct.
-
Check 3
Load the racks so no tall item, utensil, or panel edge can touch the door or detergent area, and close the door without forcing it. Check from the side that the door sits flush and that the latch engages in the same way it did before the cycle.
Expected result: The door needs pressure to latch, springs back open, sits unevenly, or closes flush with no contact; the top rack or dish was previously in the way.
Next step: Correct only the load interference and retest with the door closing normally. If the door will not latch or remains uneven, stop using the dishwasher and use the model-specific installation/service instructions rather than adjusting the latch by guesswork.
Why this matters
Why: Blomberg's FAQ directs users to verify that the dishwasher door is properly closed; loading interference can mimic a seal failure. An uneven or loose latch is a mechanical or installation issue, not a confirmed gasket diagnosis.
-
Check 4
Use the complete DWT51600FBI model and serial information to open Blomberg's matching user and installation documents. Compare any built-in panel, door, gasket, and installation instructions with the appliance as installed; do not transfer steps from a different Blomberg model or a generic dishwasher.
Expected result: The matching document confirms the installed configuration, the document is for a different model or region, or no model-specific document is available.
Next step: If the exact document confirms an external adjustment, follow it with power isolated as directed. Otherwise stop at the external checks and contact an authorized Blomberg service provider; do not remove the door assembly or panels.
Why this matters
Why: The exact model page confirms DWT51600FBI is a top-control, panel-ready built-in unit, but hardware and installation details remain document-specific. A mismatch prevents safe latch, panel, or seal adjustment.

Find the observation that best matches what you see, then follow the next safe action.
-
PATH 01Next step
What you see
Only warm vapor appears near the top during drying, there is no floor water, and the door closes flush and latches normally.
Do this next
Follow Blomberg's advice to open the door slightly after the wash so steam can escape, and monitor for actual liquid leakage or cabinet damage.
Why this path and its safety boundary
Why it matters: The observation is consistent with the DWT51600FBI condensation drying system and does not by itself prove a failed seal.
-
PATH 02Next step
What you see
A dish or rack touches the top of the door, the gasket is folded or dirty, or the door is not fully latched.
Do this next
Remove the obstruction, clean and reseat only the accessible gasket edge, and confirm the door closes without force. Stop and arrange service if the gasket is damaged or the latch remains abnormal.
Why this path and its safety boundary
Why it matters: The closure is being affected by a visible loading or gasket condition that can redirect steam or prevent sealing.
-
PATH 03Next step
What you see
Water runs onto the floor, the door opens during operation, or the door will not latch even with the racks clear.
Do this next
Stop the dishwasher, isolate power and water if it is safe to reach them, protect the floor, and request authorized Blomberg service with the model and photos. Do not continue cycles to test the seal.
Why this path and its safety boundary
Why it matters: This is not safely explained as ordinary condensation drying; a leak, closure, or installation fault remains possible.
-
PATH 04Next step
What you see
The external checks are normal but droplets or floor water continue, or the exact model documents do not match the installed hardware.
Do this next
Keep the appliance out of service and arrange model-specific inspection. Do not select a gasket, latch, or panel part from a different Blomberg family.
Why this path and its safety boundary
Why it matters: The remaining cause may be a model-specific door, gasket, installation, or internal water path issue that the public general FAQ does not distinguish.
Helpful context
Understand the symptom
Identify vapor versus a leak before changing the seal
The matching report describes a new DWT51600FBI with steam coming from the top and later says it drips onto the floor. The exact Blomberg product page lists a condensation drying system, so visible vapor around the top is expected in the drying process. A liquid stream, repeated puddle, or water escaping before the door is opened is a different observation and should be treated as a leak or closure problem until checked. Do not infer a failed latch from vapor alone.
Check closure and loading from the outside
Blomberg's official FAQ says the dishwasher door should be properly closed and its cleaning guidance says to keep the door gasket clean and free of food particles or debris. A tall plate, rack item, folded gasket, or debris at the top edge can redirect condensation or prevent the door from seating. Inspect the perimeter with power off if you need to wipe it, but do not remove the door skin or bend the latch.
Use the exact model manual for installation questions
Blomberg's model page identifies DWT51600FBI as a top-control, panel-ready built-in dishwasher and provides links to user and installation manuals. Use the model and regional document for any built-in alignment, panel, gasket, or latch procedure; the available manual portal says to search by model number. A generic dishwasher latch or seal adjustment is not a safe substitute for the DWT51600FBI instructions.
When checks do not resolve it
Need a professional?
Stop using the dishwasher and request authorized Blomberg service if water reaches the floor, the door will not latch or opens during a cycle, the gasket is damaged, or condensation remains excessive after the external closure checks. Preserve the exact model and regional documentation for the technician.
Common questions
FAQ
Is steam from the top of the Blomberg DWT51600FBI automatically a bad seal?
No. The exact model page lists a condensation drying system, and Blomberg's FAQ says to open the door slightly so steam can escape. A liquid stream, repeated puddle, or door that will not latch is different and needs service evaluation.
What should I check before calling service?
Confirm whether the symptom is vapor or water, check that no dish or rack blocks the door, inspect and clean the accessible gasket, and verify that the door closes flush and latches without force. Do not remove panels or adjust the latch without the exact model instructions.
Can I use a generic dishwasher gasket or latch adjustment?
No. The DWT51600FBI is a specific top-control, panel-ready model. Use its matching manual and installation information to identify any supported adjustment or replacement; otherwise use authorized service rather than guessing fitment.
What if condensation drips onto the floor?
Stop the cycle and treat floor water as a possible leak or closure problem rather than normal steam. Protect the floor, isolate water and power only if safe to reach, and request service with the model, timing, and location of the water.
