3 Fault Repair 3.1 Whistling Noises From Door Seal G 7882 CD, G 7883 CD Cause Fan speed in drying unit set too high. Remedy A095 2.3 Setting the Fan Speed (Air Throughput). x Note If the fan speed is reduced too much, then the drying time will be extended. 3.2 Door Seal Bulges Cause Improper detergent use over time may cause damage to the seals in the machine. The use of rinsing agents (when these contain paraffin oils) in the final rinse can also cause the seal to swell after only a short period of time. Remedy AUse a different detergent. ATo protect seals, disinfecting alkaline detergents with a high proportion of active chlorine should not be used at temperatures above 176°F (80°C).
