F18 Bosch washing machine error F18 — not draining

What it means

If your Bosch washing machine shows F18: the appliance cannot pump the water out in time.

Likely causes

Clogged drain filter, kinked or blocked drain hose, blocked household drain, faulty drain pump.

Safe steps you can try

Switch off, put a towel down and open the drain filter at the bottom to clean it. Check the drain hose is not kinked and the waste connection is not blocked.

When to call a technician

If the filter is clean and water still does not drain, the drain pump or its circuit is faulty.
