Hi, welcome to Just answer
How old is this washer ?
the problem seems to be with either the motor or the spin speed push button...also please let me know where is that popping sound coming from
Not exactly sure of age. 4-5 years it is thought.
Because popping noise occurs when it is on full spin and only intermitently it is difficult to decide where noise originates.
OK...most likely it is the switch itself that is bad and will need replacement
Ok will see about replacing the switch
