Maintaining your machine

Running a deep clean cycle

The monthly deep clean cycle eliminates bacteria and limescale throughout your machine's water system. Your machine's LCD screen and the Dyson Link app will let you know when it's time. You'll need one of the citric acid powder packets that came in your machine's Descaling Kit. Then just follow the steps in our video guide.

  • 🛈 We recommend only using citric acid when running a deep clean cycle. It's a safe, natural cleaning agent, and is widely available.

    • It's quick and easy to run a deep clean cycle

      You can run a deep clean cycle in nine simple steps. After pressing the deep clean cycle button on the front of your machine, start by following steps one and two.

    • Remove the evaporator

      Remove the evaporator from your machine, place it in the water tank and refit the cap.

  • Prepare the cleaning solution

    Remove the cap and evaporator. Fill the water tank halfway to the Max level with cold tap water. Add one packet of citric acid powder (150g) and shake gently until all the citric acid has dissolved. Place the evaporator back in the tank and fill to the Max level with cold water.

  • Replace cap and secure clips

    Make sure you wipe off any excess water to avoid drips.

Frequently asked questions

How often does the filter need to be changed?

The Combi filter needs to be changed after 12 months, based on 12 hours’ use a day.

How long can my machine humidify for?

With a full tank, your machine can humidify continuously for up to 36 hours in fan mode 1.

Can I switch off humidification?

Yes. The machine works as a purifier humidifier, or just a purifier fan.

How often should I run a Deep clean cycle?

This depends on the water hardness where you live. The machine prompts you to run the cycle once a month in hard water areas. It prompts you less often in softer water areas. You can select your water hardness with the Dyson Link app¹.

Will the humidifier overheat if it runs out of water?

No. It has a sensor to detect if it’s out of water. The screen alerts you to refill your water tank when needed.

Can multiple users share the same machine?

Yes, an unlimited number of users can use a single machine. The machine will only ever choose the most recent update. For example, if more than one person was updating the scheduling, the most recent change will be the one the machine progresses with.

Where should I place my machine?

Your machine is engineered to purify and humidify single rooms, so you should use it where you spend the majority of your time at home. When placing the machine, make sure there's at least a few feet of clearance on all sides, so that the air can circulate effectively.
