RESETTING THE HIGH LIMIT SAFETY SWITCH
All versions
Remove the cup grill and drip tray. Press the overheating safety switch reset button
to reset the device. Reassemble the machine in reverse order then power the
machine on to test heating functions.
Important:
All versions of DIAMANT Pro are equipped with redundant overheat protection (via software
in a water ling time-out feature and a mechanical EGO circuit interrupter high limit safety
switch).The rst line software protection can be reset by simply restarting the machine at the
main power switch. However, if the mechanical high limit safety switch ever trips, it must be
reset manually by pressing the reset button.
Pro Tip:
The simplest way to diagnose a tripped high limit safety switch is to turn
the machine on at the main power switch and check for a functional
displays and/or touchscreen, but with lower than expected water heating
temperatures accompanied by a unilluminated heating lamp.This indicates
that power to the boiler’s heating element is being interrupted by the
safety switch.
SMARTTEA TEMPERATURE ADJUSTMENT
All versions
The output temperature of the smart-tea dispenser is adjusted through the screw of the cold water
bypass, placed on the top panel of the machine, as shown below:
