Hi new to the board. Have a problem with my Hoover Optima washing machine. Always use the same programme “coloured” but when I put it to this setting now it comes up with different temperatures and will not let me put it to 40 (which is my usual setting). Have since used the cotton setting at 40 with no problem but it will not let me select my usual “coloured”. 🙁 Can someone assist me. Thanks
