The short answer
On a Danby dishwasher, a refusal to start most often comes back to no power at the supply — breaker, switch or outlet. Danby is a Canadian maker that specialises in compact, portable and apartment-scale appliances, so its units end up in garages, basements, dorms, offices and second kitchens far more often than in a fitted main kitchen. The brand moves one thing in particular: no power at the supply — breaker, switch or outlet ranks higher here than it otherwise would. The first two checks below are owner work and need no tools beyond what is already in the house.
What you observe
- No lights and no response to any button
- Lights on but no cycle ever begins
- A cycle that appears to start and then does nothing
- The machine beeping and refusing to run
- It worked, and then stopped after a power interruption
Ranked for a Danby dishwasher
- No power at the supply — breaker, switch or outlet — Why this rank: A dead panel is a supply question first; many machines are fed from a switch under the sink or a receptacle inside the cabinet that nobody remembers exists. — Owner checkable: true
- Door latch not proving closed — Why this rank: No dishwasher will run with the door unproven, and a latch fouled by residue or a door held proud by a tall item is the most common single cause. — Owner checkable: true
- Control lock or a delay start set — Why this rank: Both refuse a start by design and both are easy to set by accident with a wet hand. — Owner checkable: true
Check in this order
- Check the breaker and look for a switch under the sink or in the adjacent cabinet. — Because: It sits at rank 1 on this brand.
- Close the door firmly until it clicks and try again. — Because: It sits at rank 2 on this brand.
- Look for a lock or delay indicator and clear it. — Because: It sits at rank 3 on this brand.
Steps a homeowner can safely take
- Check the breaker, and look for a switch under the sink or in the adjacent cabinet — many machines are fed through one. — Tools: flashlight
About 10 min
- Close the door firmly until you hear the latch click, making sure no item is holding it proud. — Tools: none
About 5 min
- Look for a control lock or delay indicator on the panel and clear it. — Tools: owner guide if available
About 10 min
- Confirm the water supply valve under the sink is fully open. — Tools: flashlight
About 10 min
- Switch the breaker off for a minute, restore it, and try a plain cycle from cold. — Tools: none
About 15 min
- Press the float in the tub floor down and let it rise freely — a stuck float stops a fill before it starts. — Tools: none
About 10 min
- Stop condition: Stop at the first step that would require a meter on live terminals.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Nothing on this page asks you to work at a live terminal, and none of it asks you to defeat a door interlock or a safety switch — those exist to stop the machine running in a state that can injure you, and a machine that will not run with its door open is working correctly. If a breaker trips twice on the same operation, leave it off: a repeat trip is a fault to be found, not a nuisance to be reset. Stop at the first step that would need a meter on live terminals. unplug-before-service branch-circuit-15-20a
