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.

It might be time to buy a new dishwasher for your kitchen if you consistently notice a significant amount of water left over after a cycle, indicating potential drainage issues that are becoming persistent or costly to fix. Visible rust, especially on the interior tub or racks, suggests internal corrosion that will likely worsen over time and can compromise cleaning performance. Additionally, if your dishes are coming out excessively hot after the drying cycle, it could point to a malfunctioning heating element or thermostat, which can be an energy inefficiency and a potential safety concern, making replacement a feasible choice.

The average cost to repair a dishwasher that’s leaking is $200, but your total will depend on the underlying problem. Having a professional replace a faulty door gasket or a gasket in a supply line could cost as little as $50, while replacing a leaking dishwasher pump could total as much as $600.
