If your washer dryer is shooting about a cup of water into the drum at the start of the dry cycle, it is likely not a fault but a normal part of the machine's operation. Many washer dryer models use a condenser drying method, which involves introducing a small amount of water into the drum during the dry cycle.
Here's how it typically works:
Wash Cycle: During the wash cycle, water is used to clean the clothes.
Rinse and Drain: After the wash cycle is complete, the machine goes through a rinse and drain process to remove excess detergent and water from the clothes.
Dry Cycle: When the dry cycle begins, the machine uses a condenser drying method. In this process, the machine injects a small amount of water into the hot drum. As the drum rotates, the water comes into contact with the hot surfaces, turns into steam, and condenses back into water. This process helps to cool down the hot air and convert the steam back into a liquid, which is then drained out of the machine.
The purpose of this water injection is to cool down the hot air generated during the drying process, making it more efficient and allowing it to condense back into water. It's important to note that only a small amount of water is used for this purpose, usually much less than what is used during the wash cycle.
If the washer dryer is functioning properly and there are no other issues such as water leakage or abnormal noises, then the water injection at the beginning of the dry cycle is likely normal and not a cause for concern.
However, if you are unsure or notice any other unusual behavior, it's always a good idea to consult the user manual or contact the manufacturer's customer support to confirm that everything is working as intended for your specific model.
