The Zanussi ZRD 1845 Refrigerator has some known problems that occur often. Here are some easy to do solutions for the problems or error codes your Zanussi might be giving you.
The appliance is not receiving power. This could be due to a power outage, a blown fuse, or an unplugged power cord.
The appliance is not cooling as expected, which may be due to an incorrect thermostat setting, an open door, or an unsuitable location.
The compressor is operating without stopping, which can occur if the thermostat is set too low or the door is not closed properly.
Frost and ice accumulation is above normal levels, potentially due to frequent door opening or a faulty door seal.
Unusual or loud sounds are coming from the appliance, which can be due to normal operation sounds like gurgling or bubbling, or because the appliance is not level.
