I am hoping that someone here can help me. My hayward 1.5hp pump has been working fine for the last month. Today I went to turn it on and all it wants to do is hum. I checked the plugs, breakers, unplugged to reset and moved the control to recirculate instead of filter (thinking it may be stuck). All it does is hum/buzz. Called hayward and spent 20 mins on hold. Called my local pool dealer and they suggested replacing the pump thinking it was a bearing issue. Any suggestions? I really don't want to spend about $350. TIA
