Zanussi ZK73/46EF 3 Lights Flashing & Alarm Sounding

[Grzyb]

Hi All,

Have the above model, which has developed a fault.
All 3 Lights Door Alarm/Temperature Alarm & Fast Freeze are flashing & an Audible alarm is heard.

According to the manual it says "Major Alarm" & "Call Service"

Anyone have any ideas on what it could be & how much it would cost to repair.

Fridge/Freezer is about 10 years Old....

Thanks for any advice that someone mau be able to provide

Regards

Grzyb
