Dishwasher Installation questions, answered by experts

Installing a dishwasher should take one to four hours, depending on the complexity of the installation and whether you DIY or hire a pro. Even if you're particularly handy, installing a dishwasher on your own will likely take longer — at least two hours. On the other hand, a professional can likely install a dishwasher in about an hour. Installation time will take longer if you have to remove an existing dishwasher, reroute plumbing, or repair damaged flooring underneath the appliance.

Not all dishwasher noises are signs of trouble, as dishwashers naturally make sounds during operation. Normal sounds for a functional dishwasher include humming, swishing, and sloshing. However, if you hear problematic noises such as pounding, drumming, grinding, or rattling, it could be a sign of an underlying issue, and you should consider having a technician inspect your appliance.

If the dishwasher is in working condition, start and run a complete cycle with nothing inside. Let it drain and sit overnight before removing the hoses. In theory, it should effectively drain. You may find residual water in the hoses, but you can plug them. If the dishwasher breaks down midcycle it can sometimes be full of water. You’ll need to manually remove the water with a plastic cup before removing the dishwasher.

You should follow the instructions listed on the detergent packaging and in your dishwasher user manual. Often, this means inserting the tablet or pod into the detergent dispenser (and not in the bottom of the dishwasher). If you put the pod anywhere else, it might dissolve too early in the cycle and fail to clean your dishes properly.

Costs depend on labor rates, replacement part prices, brand, and whether emergency service is required.
