Rank by the event, not by the pattern
When a Whirlpool dishwasher starts faulting right after a leak, a power cut or work in the kitchen, the event is the strongest evidence available. A wet base latches the console off through the leak sensor. A power interruption leaves a latched pattern behind. Cabinet or plumbing work disturbs the supply junction and the latch strike. Each of those has a different first check, and none of them starts with a board.
What you are seeing
- The fault appeared within a day of a leak, a storm or a repair.
- The console refuses everything, including a cancel or drain cycle.
- The fault comes and goes when the machine is nudged or the door is worked.
- The machine was fine and nothing about the way it is used has changed.
- Not this fault: The machine has always blinked this way - read the symptom-first page instead.
- Not this fault: Only the drying is poor - that is a heating or rinse-aid question, not a control fault.
Ranked by what happened
- Leak sensor latched by water in the base — Why ranked: First for any machine that faulted near a leak. It is a protective latch, not a failure, and it holds until the base is dry.
- Latched pattern from a power interruption — Why ranked: Second because it is free to test and it explains a fault that arrived with no physical change to the machine.
- Supply junction disturbed by cabinet or plumbing work — Why ranked: A conductor backed out of a connector gives an intermittent, movement-sensitive fault that no board swap will cure.
- Latch strike moved when the door or the cabinet was worked on — Why ranked: Ranked here because it is common after any job near the machine and it presents as a door-open complaint.
- Connector left unseated during a previous repair — Why ranked: Last by frequency, but the first thing to look at when the fault began the day a technician left.
What to check, in order
- Write down the date the fault started and what happened that day. — Because: It selects which cause below is plausible; without it, every check is a guess.
- Kill the breaker, remove the toe kick, and feel the base pan for water. — Because: Rank one is confirmed by touch, and it explains a total refusal to run.
- Restore power after a full wait and see whether the pattern clears. — Because: It separates a latched pattern from a live fault in one step.
- With the breaker off, look at the junction box behind the toe kick for a loose conductor. — Because: Rank three is visible, and it is the cause most often missed after kitchen work.
Checks you can do safely
- Switch off the dishwasher breaker before touching anything under the machine. — N: 1 — Tools: None — Time: quick
- Remove the toe kick and feel the base pan with a dry cloth. If it is wet, leave the toe kick off and let it dry with air moving. — N: 2 — Tools: Screwdriver, cloth — Time: moderate
- With the base dry, restore the breaker and try a short cycle. Note whether the pattern clears. — N: 3 — Tools: None — Time: one cycle
- Look at the door as it closes. If the strike is out of line with the latch, the machine will keep reporting the door open. — N: 4 — Tools: Torch — Time: quick
- Stop rule: Stop here. Re-terminating the supply junction, replacing the leak sensor or reseating the console ribbon is service work.
Before you open anything
Safety
Switch off the dishwasher breaker before removing the toe kick. A capacitor can hold a charge after the power is off. These machines are commonly hard-wired, so the console power switch does not isolate them. Never reach into a wet base with the breaker on. If a leak is still active, shut the water supply as well as the power before drying anything.
When this becomes a service call
The base is wet and the source of the leak is not obvious. The pattern returns after a full power cycle with a dry base. You find a loose or scorched conductor in the supply junction. The fault began the day a repair was completed - it belongs back with whoever did it.
