Direct answer
For the Samsung DV45K6500 dryer, prove power, door switch, control lock and the Start-button hold behavior before internal repair. First, test the outlet/breaker and close the door firmly.
What this covers
- Samsung DV45K6500 dryer (DV45K6500*)
- Samsung dryer; the DV-prefix model number alone does not state electric versus gas — check the rating plate or full model suffix before applying either supply's diagnosis.
- The specific fault this record addresses: will not start
What it does not cover
- ×The same symptom on a different Samsung product line, which has its own record and its own cited source
- ×An on-screen error code whose meaning has not been checked against this exact model's manual
- ×Live electrical, gas, sealed-system, internal battery-cell or structural repair — a technician boundary, not a self-service step
Differential
What actually causes this, and how to tell them apart
These are ordered by how often each one is the answer, not by how easy it is to try. The point of the middle column is that two causes producing the same headline symptom rarely produce the same detail — that detail is what tells you which one you have before you change anything.
- 1
The door isn't fully latched even though it looks closed
What separates it The door swings shut but doesn't click, or a bulging load is holding it slightly open at the latch even though it appears closed from a glance.
How to confirm Open, redistribute so nothing is pinched at the seal, and close firmly until an audible latch click is heard.
- 2
Control lock or a child-lock mode is active
What separates it Buttons respond with a beep or a flashing lock icon rather than starting the cycle, and this began after someone pressed and held a button combination, intentionally or not.
How to confirm Check the manual for the exact lock icon and the specific button-hold sequence that disables it — it is not the same sequence on every brand.
- 3
A delayed start was set unintentionally
What separates it The display shows a countdown or a time rather than the expected cycle progress, and the dryer will start on its own later rather than never.
How to confirm Cancel the delayed start setting explicitly rather than waiting, if immediate drying is needed.
- 4
No household power is reaching the control board
What separates it The display is fully dark rather than showing an error, lock icon or delayed-start countdown — a true no-power condition looks and behaves differently from a control refusing to start.
How to confirm Test the outlet and breaker before assuming a control-board fault; see the no-power symptom for that path.
- 5
The door switch itself has failed
What separates it The door demonstrably latches with an audible click, no lock icon or delay is showing, and it still refuses to start — this is the conclusion only after the more common causes above are ruled out.
How to confirm With power removed, a technician can test the door switch's continuity in both open and closed positions; a switch reading open when the door is physically closed confirms the fault.
Before you touch a setting
Record this first — changing settings destroys the evidence
Every item below stops existing the moment a reset, re-pair or settings change is made. Written down first, they are what separates the causes above; recovered afterwards, they are guesswork.
- The exact display state at the moment Start is pressed — blank, showing a lock icon, showing a countdown, or showing nothing has changed.
- Whether the door produces an audible latch click when closed.
- Whether anyone recently pressed and held any button combination, intentionally or by leaning on the panel.
Test power at the outlet and breaker
ReversibleRule out a true no-power condition before troubleshooting the door or lock state.
Close the door firmly and confirm the audible latch
ReversibleRedistribute any load pinched at the door seal first.
Check for and clear control lock or an active delayed start
ReversibleUse the manual's exact sequence for this model rather than a generic guess.
Start and stop one empty Timed Dry cycle to confirm normal operation
ReversibleConfirm the fix holds before loading laundry back in.
Model-specific
What is true of this model and not of its siblings
Generic advice for the product line fails here. Each item below is a property of this specific model family that changes which of the steps above apply to you.
- Model scope
- DV45K6500*. Samsung dryer; the DV-prefix model number alone does not state electric versus gas — check the rating plate or full model suffix before applying either supply's diagnosis.
- Fuel — confirm ELECTRIC or GAS
- This series shipped in both electric (DVE45K6500E) and gas (DVG45K6500G) versions — check your model's suffix, because it changes the no-heat diagnosis entirely: electric = element/240V half-breaker/thermal fuse; gas = igniter/valve coils/flame sensor/gas supply.
- Venting
- A vented dryer: clogged lint screen or blocked exhaust duct is the top cause of long drying and overheating — clean both regularly.
- Features
- Steam Sanitize, Sensor Dry (cycle time varies with the load). An older-generation Samsung dryer.
- Symptom boundary
- This record covers Samsung DV45K6500 dryer when it will not start. A different symptom on the same hardware, or this symptom on a different Samsung product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
Continuing past any one of these costs more than the repair saves — in safety, in warranty, or in evidence a technician needs.
- !Unplug for a hot plug, damaged cord, breaker trip or burning smell before attempting anything else.
- !A door switch that tests as failed, or a control board with no display and confirmed good power, needs a technician.
Evidence ledger
Sources behind this answer
Visible sources support the visible claims. Home Product Support records the publisher, the fact used and the review date; community reports can suggest an issue but do not become a published fact on their own.
Where the manufacturer's article stops. Samsung Support publishes this as "Samsung washing machine information and error codes". Samsung's own washer troubleshooting and error-code article; covers filling, draining, spin and unbalanced-load conditions. What that article does not carry is the model boundary — it is written for a product line, and DV45K6500* is the scope applied here. Where a control label, terminal, indicator pattern or reset sequence differs on your unit, the manual for that exact model is the authority, not this page and not the article.
Exact questions
Common follow-ups
How do I know if my Samsung DV45K6500 is gas or electric?+
Check the full model number and the connection behind it: an electric model (…E) has a thick 240V power cord and a four-prong outlet; a gas model (…G) has a standard 120V plug plus a gas line. It matters because a no-heat fault is diagnosed completely differently — element and 240V breaker for electric, gas igniter and valve for gas.
The door looks closed but the dryer won't start.+
Check for an audible latch click — a bulging load can hold the door just enough off-latch that it looks closed without actually engaging the switch. Redistribute the load and close it firmly.
The panel beeps and shows a lock symbol when I press Start.+
Control lock is active. The button-hold sequence to clear it is model-specific — check the manual rather than guessing, since holding the wrong button can set other options instead.
The display shows a countdown instead of starting.+
A delayed start was set. Cancel it explicitly through the menu rather than waiting or repeatedly pressing Start, which won't override an active delay.
Does this answer apply to every Samsung model?+
No. It is scoped to DV45K6500*. Samsung dryer; the DV-prefix model number alone does not state electric versus gas — check the rating plate or full model suffix before applying either supply's diagnosis.
What should I record before troubleshooting won't start or not running?+
Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.
Why is a factory reset not the first step?+
A reset can erase accounts, networks, maps, schedules or preferences without distinguishing won't start, not running. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Unplug for a hot plug, damaged cord, breaker trip or burning smell.
