Hi, Bob- I don't have, and never had the SM5K, but the control circuits for
the pump would not generate the Go - Stop - Go - Stop gate for the ( triac
or power Mosfet?) driving the pump's field coil. Probably a loose wire
connector, crack in the printed wiring trace or an open pump winding, in the
order of, "I hope the problem is..."
A cheap-o voltmeter can be used to troubleshoot the thing. Even the wire may
have pulled loose from one of the terminals on the pump.
Easy fix: just tin and solder the brass grommet on the terminals, if you
find solid power to the push-on connectors or can cause the pump to
intermittently fail to vibrate just by wiggling the connector(s).
Cheers, Mabuhay -RayO, aka Opa!
