The short answer
This page covers the Bosch SBV-series dishwasher, the models whose number carries the SBV prefix. A Bosch dishwasher that will not start is usually either not latched, not allowed to start, or quietly already running. These machines are designed to be very quiet, and a cycle in progress with the door shut can be almost inaudible - so before troubleshooting, confirm the machine is not simply getting on with it.
What you observe on these models
- The panel responds but no cycle begins — The machine has power and is refusing or deferring the command: latch, delay start or child lock.
- Nothing at all - no panel, no lights, no sound — Power. The breaker, the switch under the sink or the connection behind the kickplate.
- It seems dead but the cycle finishes hours later — It was running all along. A quiet machine behind an integrated door is easy to mistake for a dead one.
- NEAR MISS - it starts but no water arrives — That is a fill problem - the supply valve, the inlet screen or the float - and it belongs on its own page.
Causes, most likely first on this family
- No power at the machine — First. The supply is usually a switched connection under the sink or behind the kickplate, which is easy to knock off and impossible to see.
- The door not fully latched — Second. The latch has to engage before anything happens, and a heavy integrated or panel-ready door needs a deliberate push rather than a nudge.
- Delay start, child lock or a programme already selected and paused — Third, and the most commonly missed: the machine is doing exactly what it was told, at the time it was told to do it.
- Leak protection triggered by water in the base pan — Fourth. The machine will drain but refuse to fill, which reads as a start failure and is really a leak report.
- The door switch, the control board or the mains connection — Last. A machine with a live supply, a latched door and no lock-out active is an electrical diagnosis rather than a guess.
- 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 fitted with an integrated door and fed from a switched spur behind the adjacent cabinet, so confirming the supply is both the least visible check and the quickest.
Check in this order, and why
- Find the switch that feeds the machine - usually under the sink - and check the breaker — On these models these models are commonly fitted with an integrated door and fed from a switched spur behind the adjacent cabinet, so confirming the supply is both the least visible check and the quickest, which is why this check leads.
- Open the door and close it again firmly until the latch engages — On a heavy custom or integrated door the latch needs a push, and a rack that is not fully home will stop it.
- Look for a delay-start or child-lock indicator on the panel — On an integrated model the panel is on the top edge of the door, so you have to open the door to read it at all.
- Switch on and listen for the drain pump running without a cycle — Continuous draining means leak protection is active; stop and look for water under the tub instead.
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 the mains connection on a built-in dishwasher sits low where water collects. Never defeat the door latch to make the machine run with the door open.
When to call a technician
Call when the supply is live, the door latches audibly, delay start and child lock are clear, the base pan is dry and the machine still does nothing. That is the door switch, the control or the mains connection, all of which are metered live behind a panel.
