What we can confirm
Code E:30 / -10, from the manufacturer's own documentation

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
Dosing pump blocked
Door not locked

About Bosch error code E:30 / -10
What this one means
Water is not reaching the machine.
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:
- A faucet icon is shown — 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:
- A closed tap
- Blocked inlet filters
- A kinked or jammed inlet hose
- Low pressure
- The level measurement system
What to try yourself
- Check the tap is fully open
- Clean the filters in the water inlet
- Straighten the inlet hose
- Wait five minutes and try once more before concluding anything
Then what
Five published causes under one code, four of them free to check. This is the clearest example on the appliance of a code that names a circuit rather than a component.
This code is published for washers. The full list of codes has the rest.
