Outstanding and friendly service! quick turnaround on install. I think their monthly maintenance program is a great concept and will save you tons of money in the long run. Only thing I thought was a bit of a hassle was having to schedule multiple people to come out just to give you a quote....

Dishwasher Installation FAQs, answered by experts

Some signs that your dishwasher is going out include:

The door no longer latches
Dishes are still dirty after a cycle
Dishes are cold after a cycle
Rust inside or outside the unit
Cracks inside the dishwasher tub
Water collecting at the bottom or outside the unit

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.

It’s not worth fixing a 20-year-old dishwasher or any 20-year-old appliance. Twenty years is beyond the useful life span of nearly every major household appliance. Once the appliance nears the end of its useful life span, repairs will become more frequent. A replacement often becomes more cost-effective at that point.

To create a siphon break and remove any chance of dirty sink water or water that backs up into the sink from getting into your dishwasher, your dishwasher drain hose needs to have a high loop or an air gap device as part of its installation. All building codes require at least a high loop. In many places, it’s necessary to install an air gap device to meet the code.

Water is sitting at the bottom of your dishwasher, likely because the filter is dirty with food debris or because the drain hose has a clog. If the water is still sticking around after following the steps above, it’s time to contact a local plumber.

Any drain in your house requires a water trap to prevent sewer gases from entering the home. Dishwashers don’t have an internal water trap, so they must use an external P trap. The most convenient P trap for the dishwasher is already in the plumbing under your sink.
