What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Diagnose the complete drain path
What they doA technician should inspect the pump cover drain pump hose air gap and downstream plumbing when E25 remains after the documented accessible checks.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Confirm that the appliance is a Bosch dishwasher
Record the model number and confirm the display belongs to a dishwasher. Do not apply this page to a Bosch washing machine because Bosch documents E25 or F25 there as a turbidity-sensor fault.
The same visible code can mean something different in another product type.

Disconnect power and remove standing water
Switch the dishwasher off and unplug it. Remove standing water with a sponge before opening the filter and pump-cover area described by Bosch.
Keep the dishwasher disconnected while the pump area is open.

Clean only the accessible pump area
Remove the filter and pump cover using the model instructions. Remove only visible loose debris and verify that the cover is undamaged and locks back into position.
Broken glass may be difficult to see. Wear suitable hand protection and never probe blindly.

Inspect the visible drain hose path
Without disconnecting inaccessible plumbing check that the visible hose is not sharply bent or crushed. If an accessible air gap is fitted inspect it only as its own instructions allow.
Stop if the hose connection is fixed inaccessible or leaking.

What it means
Bosch also documents drain-hose and air-gap restrictions as possible E25 branches. This meaning is scoped to dishwashers because Bosch uses E25 or F25 differently on washing machines.
