about Top up water tank LED.

Can I clear Top up water tank LED myself?
Pull the tank out, or fill it in place, with fresh drinking water. If it comes back, it needs a visit.
How often does a Liebherr IceMaker tank need refilling?
It depends on how much ice you use. The top up light tells you when the tank is running low.
Can I fill the Liebherr IceMaker tank without taking it out?
Yes. The manual shows it can be filled in place or taken out completely for filling.

Usually the tank is not seated all the way back. If it is seated and the light stays on, the level sensing needs a technician.
