Do I Need a Plumber to Install a Dishwasher?

We are thinking of getting our very first dishwasher. Do i need a licensed plumber to install it? I read that we can DIY however my concern is if it will be okay for insurance purposes? Also, there is a power point already in the cabinet that is currently used for water filter. Can one power point be used for both dishwasher and water filter? Thank you

    Have a look under your sink.
    It's pretty similar to a washing machine; you need at least a cold water connection (some cheap models don't have heaters and also require hot water) and somewhere to connect the drain. Often there will be a spare connector on the existing drainpipe for it.

    Installing a dishwasher is no different than installing a washing machine or refrigerator with a water dispenser. Connect the water supply and drain hose. Cheeck for leaks. Plug the power to the GPO and do a dry run before loading the dishes.

    There are plenty of vids on YouTube on how to install household appliances.

  • Will DIY be acceptable for insurance purposes, do you know?

      The connections are all user serviceable. No problem with insurance or warranty.

  • You should look at your PDS and see if it is required.

    If there has already been a dishwasher there already and you follow the instruction manual it should be hard. Just check for leakage for the first couple of days.

    If it's replacing an existing one id do it myself, if it needs pipes running I'd use a plumber.

  • This is two separate questions - do you (assuming basic skill level) need one? No.

    Does your home insurance need one? Check your PDS (as others said) or call and ask - do not assume as it'll be just dumb luck that the flexipipe that breaks (EVERYONE replace them every 5yrs) is that one you installed and they'll reject it because they can.

    If you can unscrew the stop cock under the sink and fit the dishwasher hose (may need a t piece) and you can fit the water outlet to the under sink s-trap then you do not need to be a trader to do it.

    One power point can probably be used for both, if in doubt get a sparky to switch the GPO to a double.
