The windows were cleaned to the quality standard I have come to expect from Squeegee Magic. It's possible that more training and supervision is needed for one of the technicians (Mason?). During the cleaning of one of the porch doors, a sliding screen was moved off its track. It is a difficult...

He quickly replaced my old dishwasher with a new model and I haven't had any issues at all. The plumbing appears to be done very well, it's secured and doesn't wobble around, and the dishwasher is working perfectly.

Dishwasher Installation FAQs, answered by experts

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.

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.

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.

Costs depend on labor rates, replacement part prices, brand, and whether emergency service is required.

Limescale can build up outside your dishwasher if you live in a home with hard tap water. Any household surface exposed to water and heat may have unsightly limescale deposits, including kettles for boiling water, sinks, countertops, toilets, taps, tubs, shower doors, glassware, and aquariums. Glass, laminate, porcelain, granite, and other similar surfaces can all have limescale.
