Following this logic, we make a simple conclusion. If at this stage you pour rinse aid + detergent into the tray (special compartment), then the machine will simply drain most of the liquid, like the remaining water from the previous wash. Accordingly, the quality of the wash will significantly deteriorate, because there simply won’t be enough detergent for the new cycle. As a result, things are not washed enough, remain dirty, and have a musty smell.
To wash properly, add the detergent when the machine starts filling with water. Or the second option, also very popular, is to pour the detergent/pour the powder directly onto the items in the drum.
Remember this feature of all washing machines and follow this simple advice! And your washing will be much better.
