Washing machine life profile

Dear, First, i have seen on FIDES 2009, there are 1 more rinse in the table of phases by program (§3.5.3) than in the principle of life profile (§3.5.1). •17 "fragile washing" cycles/year, with 2 rinses / cycle (1 rinse/cycle in §3.5.1) •100 "normal programs" cycles/year, with 3 rinses / cycle (2 rinses/cycle in §3.5.1) •33 "very dirty" cycles/year, with 3 rinses / cycle (2 rinses/cycle in §3.5.1) Total = 150 cycles = 433 rinses / year What is this additional rinse? It’s a preliminary rinse at 18°C before washing clothes (before programs)? Secondly, in the "very dirty" program in table of phases (§3.5.3), there are 2 phases of washing with drum at 80°C (Short wash and Normal wash). Each phase have 33 cycles/ year so 66 cycles / year in total (together). Same for the "Empty (drum at 80°C) phase" = 66 cycles. 66 cycles of “washing and empty” with drum at 80°C, but there are only 33 cycles/year of "Heating to 80°C". The same cycle of heating is used for the 2 phases of washing with drum at 80°C (short wash and normal wash). •Duration of washing (short and normal) + empty = 0.13 + 0.33 + 0.1 = 0.56 hours/very dirty cycle •During of heating = 0.26 hours/very dirty cycle The drum of washing machine can have the same temperature between 2 washes without another heating? Sincerely
