What it looks like from the kitchen
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.

The most common call Dishwasher not draining
Water standing in the bottom of the tub after a cycle. Two of the five causes come out by hand without tools, which makes this the symptom most worth five minutes before booking anything.
- Standing water after every cycle
- A code in the twenties, or four flashing lights
- Dishes clean on top, wet and gritty below
On the same appliance
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

About Bosch error code E25
What this one means
The drain path is blocked somewhere between the pump and the waste.
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:
- E25, E-25, E6102, E61-02, E6103, E61-03 — the same condition, on machines of different ages
- Four lights flashing — how a model with no digital display says it. On that machine, the lights are the code
- Active and Clean lights flashing — 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:
- The pump cover left loose
- The hose
- The air gap
- The standpipe or disposal connection
What to try yourself
- Clear the drain pump cover and reseat it
- Straighten the hose behind the machine
- Clear the air gap on the counter
Then what
This condition carries more labels than any other on the appliance — an older two-digit code, two four-digit ones, and on a machine with no display, four lights flashing above the door. All of them mean the same thing.
This code is published for dishwashers. The full list of codes has the rest.
