Rank by the event, not by the symptom
When a Whirlpool dishwasher goes completely dead right after an installation, a leak or a storm, the event is the strongest evidence available. A machine that has never powered up since fitting points at a circuit that was never energised or a junction never made up. One that died in a storm points at a protective device. One that died after a leak points at water where the supply lands. None of them starts with a new board.
What you are seeing
- The console is completely dark and no key does anything.
- The machine has never worked since it was fitted.
- It went dead within a day of a leak, a storm or kitchen work.
- It works when nudged into a certain position and dies again afterwards.
- Not this fault: The console lights but the cycle will not start - that is a control or door fault.
- Not this fault: The machine has always been unreliable - read the symptom-first page instead.
Ranked by what happened
- New install - circuit never energised, or the junction never completed — Why ranked: First for any machine that has never run. A dishwasher circuit is often left off until the install is signed off, and sometimes never switched on.
- Junction disturbed by cabinet or plumbing work — Why ranked: Second for anything that died after kitchen work. A conductor out of its connector kills the machine and survives every part replacement.
- Protective device at the control opened after a surge — Why ranked: Ranked here because it explains a machine that died during a storm with nothing physically disturbed.
- Water in the base or at the junction after a leak — Why ranked: It removes power and keeps removing it until everything dries, which is slower than owners expect.
- Shared switched circuit turned off — Why ranked: Last by frequency but free to test, and it explains a dead machine in an unfamiliar or newly rewired kitchen.
What to check, in order
- Write down when the machine went dead and what else happened that day. — Because: The event selects which cause is plausible; without it every check below is a guess.
- Find the dishwasher breaker, switch it fully off, and switch it back on. — Because: It covers ranks one and five together, and a partly tripped breaker can look on.
- Try every switch near the sink, including ones that appear to do nothing. — Because: It settles rank five, which is the cause nobody thinks of.
- With the breaker off, remove the toe kick and look at the junction box and the base pan. — Because: Ranks two and four are both visible there, and neither needs a meter to spot.
Checks you can do safely
- Identify the breaker feeding the dishwasher, switch it fully off, wait, and switch it on again. — N: 1 — Tools: None — Time: quick
- Operate every switch near the sink in turn and try the console after each one. — N: 2 — Tools: None — Time: quick
- With the breaker off, unscrew the toe kick and look into the junction box for a conductor out of its connector or browning at a terminal. — N: 3 — Tools: Screwdriver, torch — Time: moderate
- Feel the base pan with a dry cloth. If it is wet, leave the toe kick off and let it dry with air moving before restoring power. — N: 4 — Tools: Cloth — Time: moderate
- Stop rule: Stop here. Making up a junction, testing for voltage or replacing a protective device is licensed or 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. A hard-wired machine is not isolated by its own controls, so the breaker is the only safe disconnect. Never open a junction box with the breaker on, and never reach into a wet base. If a leak is still active, shut the water supply as well as the power.
When this becomes a service call
A new machine has never powered up and the breaker is confirmed on. You find a loose, browned or scorched conductor in the junction box. The base is wet and the source of the leak is not obvious. The console stayed dark after a full power cycle following a storm.
