14. Fault Finding
If there is a fault with the appliance, and controllers are installed, a numerical fault code may appear on the
digital display controller. If controllers are not installed, one may be fitted to find out the fault code. Fault
finding without controllers (and thus fault codes) is possible but more time consuming.
To diagnose and rectify faults, the Fault Finding Table is used as illustrated below:
