FAULT FINDING
If a sensor error is detected one of the following
three error codes flash alternately with the
sensor number instead of the temperature
E1 Open circuit
E2 Short circuit
E3 Temperature greater than 99°C
A code of FF indicates the fault location is empty.
The two fault code indication modes are again
mainly for use by the Gledhill engineer and can
only be used with a reference table.
The Blocking errors will clear automatically
when the fault is cleared/component changed.
The Locking errors can only be cleared by
resetting the controller.
In each case there are 16 fault locations stored
in date order with C0 being the latest and CF
the first.
The most common fault codes are shown
opposite. Not all appliances use all the error
codes available.
For further assistance please call the Gledhill
Technical Helpline on 01253 474584.

If flashing on its own system has

If flashing on its own, the system
is running normal
If both flashing indicates a fault but unit is still working
