While installing dishwasher they left deep scratches on hardwood floor. I sent him pictures and there was no reply. Also, did not attach dishwasher to countertop so when you open it tilts forward. Have to have another handyman come and fix.

Dishwasher Installation FAQs, answered by experts

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.

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.

The drain pump will naturally make a standard operational and draining sound several times throughout your dishwasher cycle. If you hear abnormally loud sounds like scraping, grinding, or clicking, you may have food debris or a piece of glass stuck in your drain filter. Avoid dishwasher repair by always scraping food off your dishes and loading the racks correctly.

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.

Descaling a dishwasher is important if you want to keep it working as efficiently and effectively as possible. Limescale builds up quickly in dishwashers that are used regularly, especially in areas with hard tap water. You need to descale your dishwasher regularly to ensure that your dishes come out clean.
