Loud humming noise when turned on. Motor and pump is not turning. Just happened yesterday afternoon with no warning. Was working fine in the morning and not making any abnormal noises. It is a Hayward SP3210X15. I see them for sale online as a motor/pump assembly. Is best option to replace both? Is the pump/motor serviceable? I will need to disassemble to find out which part seized up.
