Bosch washing machine E35-10 error code
What E35-10 means on a Bosch washing machine
Anti-flood fault, water detected in the base.
Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
When your Bosch washing machine shows E35-10, it is telling you its anti-flood protection has switched on because water has been detected in the base of the machine. You may notice a leak, or the lights flashing, and the machine will usually stop running its cycles.
Engineers sometimes find a damaged hose inside the machine, such as a hose with a hole in it, and sometimes find a small hose that has come loose from where it should be connected, letting water escape into the base.
An engineer will confirm the anti-flood fault, look for water in the base and then trace where it has come from by checking the hoses inside the machine. A hose that has simply come away can often be refitted there and then, while a damaged hose is replaced, and that part sometimes has to be ordered and fitted at a second visit. Once the repair is done, the engineer runs the machine to check that it fills, drains and spins properly.

Before you check anything yourself
- Switch the washing machine off and unplug it, or turn it off at the isolator switch, before you touch anything. Our guide to safely isolating an appliance walks you through it.
- An error code tells you where to look, not that it's safe to take the washing machine apart. Don't remove panels or covers to get at the parts it points to: that's an engineer's job.
- If it involves the mains supply, sealed parts, or you're not confident at any point, stop and book a qualified engineer rather than risk injury or further damage.
