The symptom this code usually arrives with
A code names the subsystem; the symptom is what sent you to look at the display in the first place. That page says what it usually turns out to be, cheapest cause first.
-
Often the door, not the machine 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.
- No lights at all
- Lights on but nothing happens
- Starts, then stops within a minute

What else belongs to the dishwashers
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display
Heat pump circuit
Board relay
Heating self-test
Wash arm diverter
Door sensor
Drying fan
Heat pump heater

About Bosch error code Four lights flashing with a beep
What this one means
The machine has stopped on a condition it cannot describe any more precisely.
The other ways your machine may say it
The same condition is published under more than one label, because it has been carried across generations of this appliance:
- Four lights flashing along with beeping — how a model with no digital display says it. On that machine, the lights are the code
What the code covers
A published cause names a circuit rather than a component, which is the single most useful thing to know before ordering a part. This one covers:
- Anything the machine treats as serious enough to stop for
What to try yourself
- Press ON/OFF
- Cut power at the breaker or pull the plug and wait a full two minutes
- Switch it back on and try one cycle
Then what
On a machine with no display this is the equivalent of a code the display would have shown. The two-minute wait matters — thirty seconds is not always enough for the electronics to reset properly.
This code is published for dishwashers. The full list of codes has the rest.
