The short answer
This page covers the BlueStar BS-series dishwasher, the models whose number carries the BS prefix. A BlueStar dishwasher that will not start is usually not latching, not being allowed to start, or not being fed. On a pro-style machine the door is heavy and often carries a custom panel, so the latch needs a deliberate push; and the supply is normally a hard-wired or switched connection under the sink that is easy to interrupt and impossible to see.
What you observe on these models
- The panel lights but nothing happens on start — Power is present and something is holding the cycle: latch, control lock or a delayed start. On the BS models this is the observation to trust first: it can be made from the front of the appliance without moving anything.
- Completely dead, no lights at all — Supply. The breaker, or the switched connection in the cupboard under the sink.
- It starts and stops within moments, repeatedly — The latch is reporting that it did not stay engaged, which on a heavy door is a mechanical story.
- NEAR MISS - the machine runs but never fills — That is a supply-valve or inlet problem and belongs on a different page.
Causes, most likely first on this family
- No power at the machine — First. A switched connection under the sink, a tripped breaker or a loose terminal behind the kickplate all present as a dead appliance.
- The door not latching, usually because of its weight or a rack not pushed home — Second on a panel-ready machine. Nothing happens until the latch engages, and a settled door needs more of a push than it used to.
- Control lock, delay start, or a programme already selected — Third, and the most-missed: the machine is following an instruction rather than failing.
- A worn latch, a misaligned strike or hinge settlement — Fourth. The wear item behind a door that has become stiff, and the reason it eventually stops reporting closed at all.
- The door switch, the control board or the mains connection — Last, and diagnosed only once supply, latch and lock-outs are all proven.
- Where this ranking departs from the brand-generic page — The cause that moves is no power at the machine: it leads here because these models are commonly hard-wired or fed from a switched spur behind the neighbouring cabinet, so the supply is the thing you cannot see and therefore the thing to prove first.
Check in this order, and why
- Find the switch or breaker that feeds the machine and prove it is live — On these models these models are commonly hard-wired or fed from a switched spur behind the neighbouring cabinet, so the supply is the thing you cannot see and therefore the thing to prove first, which is why this check leads. Under the sink is the usual place. A switch knocked off during a clean is indistinguishable from a failed machine.
- Push the lower rack fully in and close the door deliberately — Listen for the catch. On a heavy door with a custom panel it needs a push rather than a nudge, and a protruding handle will stop it short.
- Look for a control-lock or delay indicator and clear it with the documented sequence — Guessing at key combinations changes settings instead of clearing them.
- Look at the strike and the latch for wear and alignment — A door that has needed a shove for months is telling you this is coming.
Before you open anything
Safety
Switch the machine off at its breaker before removing any panel - a capacitor can hold a charge after the power is off, and on a hard-wired machine there is no plug to pull as a second line of defence. Do not defeat the door latch.
When to call a technician
Call when the supply is proven live, the door latches audibly, no lock-out is active and the machine still does nothing - that is the door switch, the control or the mains termination, all metered live behind a panel. Call as well for a latch that needs force, because on a heavy door that is hinge and strike alignment rather than a part swap.
