Fast response, super professional, knowledgeable! Highly Recommend! Installed a microwave and dishwasher within 24 hours of our request. Faster than the appliance stores service. Service was 2 days before New Years holiday! I couldn't find any service before the holiday. Very grateful to Noori...

Diagnosed the problem with dishwasher, unfortunately the required part is no longer available. I asked about a problem with our stove while he was wrapping up and he did a tune up for me on the burners and gave me a discount on that work.

David was prompt, courteous and professional. I hired him back for a refrigerator repair after watching him work on my dishwasher. In both cases, I thought he was more competent than the original installer. He's going to be my go-to appliance guy.

perfectly. The total price for purchasing a high quality dishwasher which matched the refrigerator I purchased 2 years ago, install it and remove the old one was less than the purchase price alone of a new dishwasher even using our military discount! It was just so easy to have TruBlue handle...

Dishwasher Installation questions, answered by experts

Common issues include drainage problems, faulty doors, inconsistent cleaning performance, unresponsive controls, or unusual noises.

The answer is a resounding yes, as dishwashers save significant water and energy compared to washing dishes by hand. The difference is so drastic in fact that those who use energy-efficient dishwashers can expect savings of over $450 per year. This is because dishwashers use less water, they wash at a higher temperature than a hand rinse, and you don’t need to rinse them after washing. New dishwashers use around 4 gallons per load, whereas washing by hand can use up to 2 gallons per minute.

Some signs that your dishwasher is going out include:

The door no longer latches
Dishes are still dirty after a cycle

If your dishwasher is not energy-efficient or is older than 10 years, you should also consider replacing it. Repairing an older model may be more expensive than replacing it with something newer and more energy- or water-efficient.

Repair costs vary by issue, typically from $100 to $500, depending on the parts needed and labor involved.

Professional repair is advisable for electrical issues, refrigerant leaks, or unfamiliar problems. Technicians can accurately diagnose and fix such problems, ensuring safety and appliance longevity.
