7.1 The electronic control system of the Supreme has a self-
diagnostic feature which determines if the unit is operating
satisfactorily. If it is not operating correctly the nature of the fault
is ascertained and a fault mode is indicated.
7.2 If steam or boiling water discharges from the vent pipe the
Supreme will switch off. Other critical faults are indicated by the
indicators flashing. The cause of the fault will be indicated by
which is flashing (see Section 8.0 FAULT FINDING). A critical
fault would render the unit unsafe to use and so will deactivate
both the element and solenoid valve.
7.3 The Supreme incorporates an electronic scale conditioning
function which will reduce the rate of scale deposition in hard
water areas. However, in extreme circumstances some deposits
may still occur in the storage tank, these should be periodically
removed.
