The water level settings in a washing machine are typically represented by numbers, such as 1, 2, 3, etc., or small, medium, large. The exact volume of water corresponding to each water level can vary depending on the specific make and model of the washing machine. Unfortunately, without knowing the specific model of the washing machine, it is not possible to provide an exact value for water level 1 in liters.
To find the exact water level capacities for each setting, refer to the washing machine's user manual or look for the specifications on the manufacturer's website. The user manual should include a detailed chart or table indicating the water levels for each setting, which will give you the precise volume in liters.
