My washing machine used to wash clothes super clean, and white shirts and socks were super white when thrown into the leader's mouth. I haven't cleaned anything recently Does anyone know?

1. Reasons for changing washing powder or liquid detergent. (Just find the right brand)

The speed of the washing machine or the execution time of the program are not as good as before. This can only be solved by changing parts. (If it is within three bags, see the after-sales door. If there are more than three bags, you can consider changing one. )

3. The dirt in the inner barrel of the washing machine has not been cleaned for a long time, causing secondary pollution to the washed clothes. (a) Buy washing machine cleaning agent and clean the inner barrel. B, find the after-sales door to dismantle and wash the inner barrel. C. If the washing machine has been used for too long, directly replace it with a no-clean washing machine. At present, Haier has done a good job of cleaning-free. )

These are probably the three situations ~ I hope to adopt with pure hands ~
