#1 Does this model have a decibel noise rating... Also when you say it can be self installed-- does it mean we need a wrench or tools..
We do not say this model should be self installed and would recommend having a licensed plumber install this model.
#2 Do you need to buy any additional parts, to enable you to install the dishwasher yourself, such as a power cable/drainage hose?
Most of our dishwashers on our website come with parts which allow you to install the unit yourself. You may also need an electrician for any extra work that may be required.
#3 How does it work with only a cold water inlet?? Does it heat the water itself?
This washing machine only takes a cold inlet as it heats the water it self.
