Dishwasher Installation questions, answered by experts
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.
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.
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.
Yes, even a small dishwasher leak is a big deal. While it might seem minor, continuous unnoticed drips can lead to significant water damage to your kitchen floor, subfloor, and cabinetry. This damp environment is also a perfect breeding ground for mold, which can cause health issues and expensive mold remediation. Remember that water and electricity don't mix—having even a small leak poses a potential electrical hazard. Addressing any leak as soon as possible protects your home and avoids costly future repairs.
Yes, a dishwasher needs an air gap to prevent backflow. Additionally, in many locations, air gaps or another measure to prevent backflow are required for building code compliance. There are alternatives to an air gap, like a Studor vent or a loop and trap design, but an air gap is the simplest and most popular solution.
