We would advise if your model had a child lock this will be documented at the back of the user manual and will advise on how to use. If SMS25AB00G is your model, this does have a child lock.
#2 This model does not have an Auto programme however, the most economical programme to use will be the Eco wash. This will save you energy and water consumption.
Is there an 'auto' wash programme for this dishwasher? If not, which programme is recommended to be used as default/standard? (with energy/water usage in mind)
#3 Just bought this dishwasher, washing for first time on Eco50 , time shows 3.30hrs can this time be shortened, what is the washing time for Quick 50
The appliance has a vario speed plus program which improves the time of the dishwashing program. The quick 45 program is 29 minutes long.
