Symptom
Bosch dishwasher will not start
A machine that does nothing, starts and stops, or lights up and never fills. Door and power account for most of these, and both are worth checking before anything is booked.

Five ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
The door is not latching
Press it firmly shut and listen for the click. A rack pushed out slightly, or a tall handle, stops the latch engaging fully.

The door switch
The latch closes but the switch behind it does not report it. This has its own published code and it is a modest repair.

Power
The breaker, or the outlet under the sink that shares a switch with the disposal. A dead machine with no lights at all is power until proven otherwise.
-
Low supply voltage
The machine publishes a code for it. It is about the building or the circuit rather than the dishwasher, and replacing parts will not help.

Child lock or a delay timer
Both are easy to set by accident and both look exactly like a broken machine.
In five minutes
Before you call anybody
None of it needs tools, and all of it makes the visit shorter.
-
01
Close the door properly
Firmly, and listen for the click. Then check the lower rack is pushed fully in and no handle is fouling the door.
-
02
Check the breaker and the outlet
Including the switch by the sink that people forget controls the outlet under it.
-
03
Cut power for five minutes
At the breaker, genuinely off rather than standby. A surprising number of machines come back after this, particularly after a power cut.
-
04
Check for a delay or a lock
A delay-start set by accident, or the child lock. Both are in the manual and both are free to clear.
How it shows up
What people describe when they call
Two shortcuts
Narrow it down before anybody arrives
A description of the behaviour leaves a few possible causes. A code names the subsystem, and the model number says which parts to bring. Either one shortens the visit; both together usually settle it.

About Bosch dishwasher will not start
The fastest diagnosis is the code
A dishwasher that will not start is very often a dishwasher that does not believe its door is shut. There is a switch the latch operates, and if it does not close the machine will not begin — which is deliberate, given that the door is what keeps the water inside.
Door, then power, then the board
Those three, in that order, explain nearly all of these. The door has to latch and a switch has to confirm it before the machine will do anything, which is sensible in an appliance that fills with water. Power includes the outlet under the sink that shares a switch with the disposal — an outlet a great many people do not know is switched at all.
The voltage code
These machines publish a code for a supply that is too low, which is a genuinely useful thing to be told. It means the problem is upstream of the dishwasher, and no part inside it will improve matters. In older buildings and on long runs it is a real finding rather than a curiosity.

Before you book
Questions about bosch dishwasher will not start
It hums but never fills.
That is a different problem — water supply rather than start-up. Check the valve under the sink is open and the inlet hose is not kinked, and look for a supply code.
It started doing this after a storm.
Common here. Five minutes genuinely off at the breaker fixes a fair number. Those it does not fix often have real surge damage, and that timing is worth telling us.
The lights come on but the buttons do nothing.
Check the child lock first — it is usually a button held for a few seconds and it is easy to trigger while wiping the panel down.
