FAULTS AND REMEDIES

Warning! The operations should be carried out by a qualified professional.
9.1 DIAGNOSIS AND OPERATING ANOMALIES
This section includes the typical anomalies that could occur.
Many of these problems are not caused by the cooler, but they could be brought about by the electricity supply or by an incorrect use of the water cooler.
In the ANOMALY column, the problems reported by the customer are listed.
In the POSSIBLE CAUSES column, the "probable reasons" behind the problem are listed.
In the INTERVENTION column, the corresponding corrective action is listed.
Warning! If the appliance is equipped with a chlorine filter, proceed as
follows:
Remove the filter cartridge and fit on the false cartridge mod. TEST CAN.
• With the help of a pump P, connect the appliance's water inlet to the container with
the disinfecting solution.
• Start the pump up so a disinfectant solution enters the machine and then, at the same
time, open the taps so that the disinfectant runs from the distribution nozzles.
• Before the solution runs out, stop the pump and interrupt the dispensing.
• Leave the disinfectant to act for at least 20 minutes.
• Reconnect the appliance to the mains water supply.
• Let at least 15 litres of water flow out of the taps so as to rinse the hydraulic system
suitably, before using the appliance again.
