Service Rainwave 800 Washing machine model 952901796?

Re Service Rainwave 800 Washing machine which I bought secondhand without instruction book. When set on programme 6 for acrylics/delicates (40 degrees) it just fills up with cold water, keeps rotating, filling with cold water a few times then emptying and spinning - finishing with the washing powder particles all over the clothes due to no hot water infill on this programme. I have just washed on a 60 degree cycle and had no problem with hot water fill.
