Direct answer
For the GE GDF510 dishwasher, prove power, door latch, control lock, delay and Start/Resume behavior first. First, reset the breaker once and close/latch the door firmly.
What this covers
- GE GDF510 dishwasher (GDF510P*)
- GE/GE Profile dishwasher; Dry Boost, bottle jets, UltraFresh and Wi-Fi equipment varies.
- The specific fault this record addresses: will not start or respond
What it does not cover
- ×The same symptom on a different GE 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 is not latched positively
What separates it The panel lights but pressing Start produces nothing, or the machine beeps and stops. The latch has to close a switch before anything runs.
How to confirm Push the door firmly until it latches. A slightly proud door looks closed and is not.
- 2
Control lock is active
What separates it A lock icon shows on the panel and buttons beep without responding. Easily triggered by wiping the panel down.
How to confirm Clear it with the model's documented button-hold sequence, which differs between brands.
- 3
A delay start is running
What separates it The display shows a countdown or a delay indicator rather than cycle progress, and the machine will start later on its own.
How to confirm Cancel the delay explicitly rather than pressing Start repeatedly.
- 4
The previous cycle was interrupted and needs resuming or cancelling
What separates it The machine resumes a partly finished cycle rather than starting the newly selected one, or refuses a new selection.
How to confirm Run the documented cancel or drain sequence to clear the interrupted cycle before selecting a new one.
- 5
No power is reaching the machine
What separates it The panel is completely dark. Many dishwashers are wired to a switch under the sink or a dedicated breaker rather than a visible plug.
How to confirm See no-power — check the breaker and any switch under the sink before assuming a control 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.
- Whether the panel is dark, or lit but unresponsive — these are entirely different problems.
- Whether a lock icon or a delay countdown is showing.
- Whether the door latches with positive engagement rather than just resting closed.
- Whether the previous cycle completed normally.
Push the door until it latches positively and try Start again
ReversibleA door resting closed without engaging the latch switch stops everything.
Check the panel for a lock icon or a delay countdown
ReversibleBoth are far more common than a control failure, and both clear with a documented sequence.
Run the documented cancel or drain sequence to clear an interrupted cycle
ReversibleA machine holding a part-finished cycle will not accept a new selection.
Check the breaker and any switch under the sink if the panel is dark
ReversibleMany dishwashers are hard-wired to a wall switch rather than a visible plug.
Start and cancel one empty cycle to confirm normal control response
ReversibleConfirms the fix before committing a load.
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
- GDF510P*. GE/GE Profile dishwasher; Dry Boost, bottle jets, UltraFresh and Wi-Fi equipment varies.
- Type — entry front-control, plastic tub
- An entry GE front-control dishwasher, often with a plastic tub and a heated-dry element rather than Dry Boost. The plastic tub holds less heat, so lean on Heat Dry and rinse aid; keep plastics off the tub floor near the element.
- Wash
- A basic cycle set with a manual filter at the tub floor — clean it periodically, the top cause of poor cleaning and odour.
- Drain path
- 'Won't drain' is usually the filter, drain hose, air gap, or an un-removed disposer knockout plug.
- Symptom boundary
- This record covers GE GDF510 dishwasher when it will not start or respond. A different symptom on the same hardware, or this symptom on a different GE 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.
- !Stop for hot wiring, smoke, arcing, or repeated breaker trips.
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. GE Appliances publishes this as "Owner support". Official GE and GE Profile model manuals, troubleshooting and service entry point. What that article does not carry is the model boundary — it is written for a product line, and GDF510P* 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
Does the GE GDF510 have Dry Boost?+
Usually not — the entry GDF510 typically uses basic heated drying rather than GE's Dry Boost fan system, and often has a plastic tub. So drying is weaker, especially on plastics. Enable the Heat Dry option, keep the rinse-aid tank filled and raised, and open the door after the cycle. For strong plastic drying you would need a GE with Dry Boost (GDT/PDT models).
I press Start and nothing happens, but the lights are on.+
Lights on means power is fine, so it is a permission problem. Push the door until it latches positively — a door resting closed without engaging the latch switch is the most common cause — then check the panel for a lock icon or a delay countdown, both of which stop a cycle starting and both of which clear with a documented button sequence.
Does this answer apply to every GE model?+
No. It is scoped to GDF510P*. GE/GE Profile dishwasher; Dry Boost, bottle jets, UltraFresh and Wi-Fi equipment varies.
What should I record before troubleshooting won't start or not responding?+
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 responding. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Stop for hot wiring, smoke, arcing, leaks or repeated breaker trips.
