When tub is plugged in (110 V), the pump/jets run at low speed, and heater light is steady red. When we try to increase speed, the motor makes a humming sound, and the light on the GFCI plug goes off momentarily. The pump then continues to run at low speed. The circuitboard was replaced about 2 yrs ago. We noticed some tarnish on the contacts of the power plug and cleaned that off, but that did not help. Thanks.
