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.
-
Door, power or supply Washer will not start
A machine that does nothing, or one that lights up and never fills. The door lock and the water supply account for most of it, and both are worth a minute before booking.
- No response at all
- Lights on but the cycle never begins
- Starts, then stops without filling
On the same appliance
What else belongs to the washers
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
Drain pump blocked
Drain path restricted
Drain blocked or kinked
Pump obstructed
Water in the base
Door not locked

About Bosch error code E:10 / -00 / -10 / -20
What this one means
The pump for the automatic detergent dosing system is blocked.
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:
- The dosing pump unit
- Detergent that has dried in it
What to try yourself
- Put the machine into standby and clean the dosing pump unit
- Consider switching the automatic dosing off temporarily so the machine can be used
Then what
Only the machines with automatic dosing have this. Thick detergents and long gaps between washes are what dry in the unit, and it can be turned off manually while it waits for a repair.
This code is published for washers. The full list of codes has the rest.
