Washer shows E13 and may stop with water in the base tray; often accompanied by the drain pump running continuously.

Safety first: Unplug the washer and turn off water supply immediately. Be prepared for water spillage when tilting the machine.

Step-by-step checks:

• Access base tray: Carefully tilt the washer backward and look underneath. Many Rosières models have a base tray with a float switch.
• Drain the tray: If water is present, soak it up with towels or carefully tip the machine to pour water out (protect the floor).
• Locate the leak: Remove side or rear panels and inspect all hoses (inlet, sump, drain), the pump, and the tub for drips or water marks. Run a short fill cycle while observing (with panels safely in place and no exposed live parts).
• Secure or replace components: Tighten hose clamps, replace cracked hoses, and if the pump housing or tub is cracked, replace the affected part.
• Check float switch: Ensure the float moves freely and the switch is not stuck in the activated position. Clean or replace if necessary.

Warning: Do not bypass the anti-flood system; it is a critical safety feature.
