The short answer
BDBU models take this one slightly differently. A dishwasher that will not start is usually not getting told to, rather than unable to. The door latch, a delay timer left set, an active child lock and a control that needs a reset account for most of these before any component is suspected. The departure from the generic page is in where the first check goes.
Signs and near misses on a BDBU unit
- The door will not latch with a positive click — The latch is the interlock the control reads. No click, no cycle. It is the first thing worth confirming on a BDBU unit.
- A hum for a moment and then silence — Power is reaching something. That is a different branch from a dead panel.
- Standing water in the tub from the last cycle — Many machines refuse to start a new cycle until the old water is dealt with.
- NEAR MISS: the machine starts and stops part way through — That is a cycle fault rather than a start fault, and the drainage page is often the right one.
Causes in likelihood order on the BDBU line
- A door that is not latching properly — Ranked first. The control will not begin a cycle until the door reads as closed, and a latch that has dropped or a hinge that has sagged produces a machine that looks dead and is not. On the BDBU models this stays at the top because nothing about the platform makes it less likely.
- A delayed start left set from a previous cycle — The machine is doing exactly what it was told. It is worth ruling out before anything is opened.
- Water left standing from the previous cycle — Many controls refuse a new cycle rather than washing in old water, so a drainage fault presents as a start fault.
- A failed control board or thermal cut-out — Last, and the least likely. It is what remains after everything above has been eliminated, and it is not an owner repair.
Where to start, and why
- Look for a lock or delay indicator on the panel — Both are settings, both look like faults, and both are cleared in seconds. The BDBU layout is the reason it comes first here.
- Check whether water is standing in the tub — Many controls will not begin a cycle over old water, so this is a start fault with a drainage cause.
- Cut the power for a few minutes and restore it — A control reset clears a surprising number of unresponsive machines and costs nothing.
- Watch whether the breaker trips when the cycle is started — If it does, stop: that is a fault that needs a technician, not more attempts.
Isolate it first
Safety
Isolate the appliance at the breaker before a screwdriver touches a panel. Stored charge outlives the switch. The door latch and its wiring are part of the machine as designed; leave them exactly as they are and never wedge, tape or prop the door.

When to call a technician
The owner side of this fault is everything you can do from the front of the machine without a tool. Call for anything beyond it, and call the same day if there is any smell of hot plastic.
