The past couple (ok, few) days I've had a blinking coolant light despite
having a full pressure tank and good level in the reservoir.  Finally
got some time today and pipetted some coolant form the pressure tank and
removed the level sensor. Sure enough the probe tips were coated with a
dark slime.  Wiped it off and all is well.
