If the machine suffers from poor performance and the low pressure
switch(es) trip and cannot be reset (the fridge fault lights also
illuminate) then this may be a symptom of a refrigerant leak.
Put the unit is Standby mode and isolate from the power supply.
Contact a refrigerant technician authorised in accordance with EU
517/2014 as soon as possible.
