If the selected appliance code does not match with the ID resistor fitted to the
appliance, then, an error ‘33’ will be displayed.
A table showing this and other common fault codes is shown below.
Fault Codes
Fault code locations are numbered C0 - CF and
c0 - cF.
CO/cO locations hold the latest fault recorded.
A code of FF indicates that the fault location is empty.
If a sensor is faulty instead of a temperature it will show E1 if open circuit and E2 if
short circuit.
Any other code displayed should be checked against the full chart.
Please ring Gledhill Technical Helpline for details.
