The 'relay' you hear clicking when the first pump is supposed to run indicates that the microswitch on the handle is working correctly, it could be the the contact tips of the contactor (not really a relay) are worn out and not making or possibly the brushes in the first speed motor are worn out or seized in their holders. Take the panel off behind where the driver stands to check the contactors, take the large dash cover off to check the motors. Can't remember if the pump motors are individually fused, could be a fuse blown if so, also behind the aforementioned panel.
