Page 187: Regular Maintenance
Regular maintenance Regular maintenance To maintain correct and proper functioning and to prevent interruption of service, the following maintenance scheme should be adhered to. The maintenance interval should be adapted to how frequently the machi- ne is used. Daily • Check the door and door lock: - Let the door remain open and try starting the machine. The machine should not start.
Page 188 Regular maintenance - Verify that all internal hoses do not leak. - Inspect the drive belt. Adjust the tension or replace if necessary. - Check that water does not leak onto the floor. - If the heating time is unusually long, check the heating elements. If the water is very hard, check whether there are lime deposits on the heating elements. Decalcify the elements if necessary. Adapt the amount of deliming agent to the manufacturer’s guidelines. - Never switch on the heating elements when there is no water in the machine. This will cause the slow-blow fuse to trigger.
