Alternatively you can open all the windows for 5 minutes to lower the humidity and get a fresh air.
The correct humidity is very important, so we keep the wetness and therefore mould around windows away. You will also feel warmer.
If the windows get too wet in the morning, please use a cloth to dry them and start to use dehumidifier more.
The dehumidifier is working only when the led light marked by arrow ⮕ is on. The humidity shown on the display may be wrong (outdated) and it may stop working because of it. The workaround is to turn it off and on again when it happens - few times a day. Alternatively you may use the “Co” (continuous mode) to make it work all the time.
