Bosch washer dryer E06 error code
What E06 means on a Bosch washer dryer
Drain fault: the machine cannot empty water.
Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
On a Bosch washer dryer, the E06 code means the machine has a drain fault and cannot empty the water out. You will usually notice that it is not draining, and water left in the drum can sometimes overflow and leak out through the soap drawer.
Engineers sometimes find small objects and fluff caught around the drain pump, such as lint or a hair clip wrapped around the part that spins to push water out, so the pump hums but cannot clear the water. They also sometimes find a blockage further along, inside an extension fitted to the drain hose, even when the pump and filter look clear.
An engineer will typically test the fill and drain, check the filter and pump for debris, and look along the drain hose and any extension for anything trapped inside. To put it right, they usually clear out whatever is blocking the pump or hose. Where an extension is causing the trouble, they may remove it and connect the original drain hose straight to the waste pipe to shorten the drain run, then run rinse, spin and drying tests to make sure the machine empties properly.

Before you check anything yourself
- Switch the washer dryer 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 washer dryer 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.
