Strange symbol!

I have a 3 rd generation Nest thermostat , had it about 3 years, which has given me some problems, , with some help and a factory reset seem to be resolved.

However, today a new not seen before symbol appeared, the heating was off, outside of the scheduled times, but the boiler started up on its own, and this new symbol appeared  at the bottom in yellow,  I cannot find out what it represents, also the reset button was illuminated on the boiler……..

Nest Thermostat has a built-in Legionella bacteria prevention program.  Symbol: water drop within a circle.

Tricky to turn off - but can be done?

1) Press your thermostat ring to bring up the Quick View menu

2) Select Settings

3) Select Equipment and Continue

4)  Choose Bacteria Prevention on or off

 

 

 

Hi, my bacteria setting is already switched on, I have never seen that symbol before!?
