Hoover washer dryer E20 error code
What E20 means on a Hoover washer dryer
Drain fault: the machine cannot empty water.
Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
On a Hoover washer dryer, the E20 code is a drain fault: the machine cannot empty its water. You may find water left sitting in the drum, and the machine may also refuse to spin.
Engineers sometimes find a blockage in the drain filter, built up from fluff and small items such as coins and screws, or a blocked hose inside the machine leading to the pump. Sometimes the filter itself is damaged and will not come off by hand. Engineers also sometimes find the code showing even though the machine drains properly, because the part that senses the water level has failed.
An engineer will typically drain off the standing water and check the waste pipe, the filter and the hose inside for blockages. They clear whatever they find, then run a rinse and a drain to make sure the machine fills, drains and turns the drum without leaking. If the filter is broken, they replace it, sometimes together with the drain pump it fits into, and a faulty water level sensor is replaced. Where a part is needed, it often has to be ordered and fitted at a second visit.

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.
