Unable to Manually Start Deep Clean | Dyson Community
Skip to main content

Hi everyone,

I have a Dyson Purifier Humidify+Cool Formaldehyde PH04 which has grown a large amount of mold/algae in the water tank.

I would now like to deep clean the machine but, unfortunately, have been unable to determine how to manually initiate a deep clean cycle.

To reiterate, the machine does not show that a deep clean cycle is needed but I would like to manually start one.

Any assistance or advice would be greatly appreciated.

Thanks!

This is possible by pressing the deep clean cycle above the power button twice. Power on the machine, press the deep clean button and the machine shows how dirty the evaporator is. After that just press the deep clean button again and the deep clean process should start.
