E23 Bosch washing machine error E23 — water leak

What it means

If your Bosch washing machine shows E23: the leak protection (Aquastop / base-pan sensor) has detected water and shut off the supply.

Likely causes

Leak from an internal hose or joint, damaged door seal or gasket, cracked tub, excess foam, leak at the inlet hose connection.

Safe steps you can try

Turn off the tap and unplug the appliance. Look for water underneath and at the hose connections. Use less detergent.

When to call a technician

If there is a leak, do not use the appliance: the leak must be fixed and the Aquastop system reset.
