Washer displays E25; drain pump blockage or failure on some Bosch variants

Safety first: Disconnect power and prepare for water spillage.

• Clean pump filter: Open the lower flap, drain residual water, and remove the pump filter. Clear all debris.
• Inspect impeller: Look inside the pump housing and remove any objects. Ensure the impeller is firmly attached to the shaft and spins freely.
• Test pump: After cleaning, reassemble and run a drain cycle. If the pump is noisy, seized, or not running, replace the Bosch drain pump.
