5.7 Making equipment safe after incomplete operating cycle
If an incomplete cycle has occurred, it is assumed that the load being processed has not been subjected to a complete
cycle as per the set process parameters. For this reason access to the load is restricted and will not be allowed until a full
cycle has been completed. At the end of an incomplete cycle or on powering up the device after an incomplete cycle, a
fault code will display relating to the cause of the incomplete cycle (Please see section 5.6 Fault Codes for description of
fault code). Depending on the nature of the fault a purge reset option may be available; this can be done by following the
instructions as per section 5.9 of this manual. If the device does not allow a purge reset to be completed, or the fault re-
occurs after a purge reset, it is recommended that the device is isolated and service is arranged to correct the fault.
5.8 In case of malfunction
In the event of a fault or malfunction with the device during operation, abort the cycle by pressing the Power On/Off
button on the control LCD. Once the device is off, isolate the mains power supply and both the hot & cold water services.
Notify maintenance or service provider of the fault and ensure device is not used until the fault is rectified.
