Technician has phenomenally quick response; came out same day of the call. Diagnosed the failure of my GE dishwasher’s motherboard. Efficient and explanatory with information. Courteous and clean in his process. Cost was commensurate with the repair. I would definitely recommend Sun Home Service.

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.

Installation includes leveling the unit, connecting water and electrical lines, securing the unit, and testing for function and leaks.

A dishwasher filter should be replaced every five years, depending on the manufacturer's recommendations and the frequency of use. The exact timing can vary based on factors such as the hardness of your water, how well you rinse dishes before loading them, and how often you clean the filter. Regularly inspect the filter for signs of wear and tear or damage. If the filter appears worn out, damaged, or excessively clogged despite regular cleaning, it should be replaced sooner.

Dishwashers should be cleaned a minimum of once every 3 months, but really it should be done monthly. This is to prevent germ buildup and will help keep your machine running smoothly. Dishwasher maintenance isn’t too difficult, you’ll simply clean the filter, wipe down the spray arms with vinegar or rubbing alcohol, and run the cycle on empty. If there is any debris, you can remove it with a small metal pick. Do not use wood as the tip can break off inside the machine.

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.
