Aquabot Turbo T Water Pump Pulses on-off-on-off

I have a Turbo T which is 3 years old. The water pump starts up for about 20 seconds then continuously alternates from on to off to on to off to .... in about 1 second intervals. Motor works fine. I've pulled out the pump and cleared all debris from the propeller. Wire connections look good.
