Dave did great work installing my kitchen faucet. He noticed the garbage disposal hose was not secure enough so he took a trip to lowe's to get a hose clamp to ensure the job was done correctly. I'd definitely recommend Dave for all types of projects.

Good job repairing the dishwasher. However, a cable to garbage disposal was knocked loose. Didn’t show up the next day, but fixed it the following day.

Dishwasher Installation questions, answered by experts

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.

Some common signs you have a dirty dishwasher filter are:

Food sticking to your dishes even after a thorough wash cycle
Odor coming from your dishwasher
Stains left on dishes and utensils
Water pooling in your dishwasher
Food stuck to parts of the dishwasher, like the racks, walls, or sprayer arm

Repairs typically cost between $150 and $600, depending on the issue, parts needed, and labor charges.

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.

Most repairs take 1-3 hours, but complex issues requiring part replacements may take longer if parts need to be ordered.
