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.
-
Film, grit or dishes still dirty Dishwasher not cleaning properly
Dishes coming out gritty, cloudy or with food still on them. In a hard-water city a good share of this is scale and detergent rather than a failed part — and the machine will eventually tell you so with a code of its own.
- Grit left in glasses and cups
- A white film on everything
- Food still on the lower rack

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
Door sensor

About Bosch error code E05
What this one means
The circuit that switches water between the spray arms is not responding.
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:
- E05, E0106 — the same condition, on machines of different ages
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 diverter valve
- Its circuit on the control board
Worth doing before you call
- Look at whether one rack is coming out clean and the other is not — that is the same story from inside the tub
Then what
A diverter that has stopped switching leaves half the machine washing and half of it not, which is why this often arrives as a cleaning complaint rather than as a code.
This code is published for dishwashers. The full list of codes has the rest.
