Your Flush uses the water tank on its right side to keep the humidity up for your mushrooms. When the tank runs dry, the screen shows Water tank low.
Refill the tank
- Push to open the water tank on the right side of your Flush.
- Fill it with clean drinking water.
- Check the hose is inside the tank, right down in the water.
- Push the tank back in, making sure the hose doesn’t get caught behind it.
- Tap Refilled on your Flush’s screen. It tops up the humidifier and carries on.
Still asking for water after a refill? Check the hose first. If it has slipped out of the water or is pinched behind the tank, your Flush can’t draw water. Reseat it, then tap Refilled again.
