Its a longer heated prewash
Ciao Carlo,
When you select the 'soak' option on the dishwasher, it heats the water to approx 40 - 50 degrees and the soak phase extends the prewash by 15-20 minutes.
I have used this in combination with the 'Normal 55' or 'Intensive 65' programme. It cleans baked on / dried on soiling very well. I add some detergent to the prewash compartment. Either CareCollection dishwasher powder or tabs.
