You should replace your dishwasher every 10 to 12 years on average. Entry-level models may only last 7 to 10 years, while high-end models can last up to 15 years. However, the decision often comes down to performance, repair costs, and safety.
You should replace your dishwasher if it is over 10 years old, has a cracked or rusting tub, or is actively leaking. As a general rule of thumb, you should also opt for a replacement instead of a repair if the repair costs more than half the price of a new unit.
The 50/50 rule is a financial guideline used to decide whether to repair or replace a broken home appliance. It states that if an appliance is halfway through its expected lifespan, and the cost of repair is 50% or more of the cost of a new, comparable unit, you should replace it.

Dawn dish soap (or any liquid hand soap) produces excessive suds in a dishwasher. The aggressive, high-foaming surfactants cause a massive overflow of bubbles that can flood your kitchen and severely damage the appliance’s motor and electronics.
The most common dishwasher failure is poor drainage or standing water at the bottom of the tub, which is usually caused by a clogged filter, a blocked drain pump, or a kinked drain hose. This prevents the machine from running or cleaning dishes effectively.
Common signs a dishwasher is failing include standing water at the bottom, dishes remaining dirty or spotty, unusual grinding noises, or visible water leaks. Additionally, if your unit is more than 10 years old or the dishes come out completely cold and wet at the end of a cycle, it may be nearing the end of its lifespan.
Small appliances with the shortest lifespan typically include kitchen appliances like toasters, blenders, and coffee makers. These tend to have more limited warranties and are generally less durable compared to larger household appliances like refrigerators or washing machines.

A 7-year-old washing machine is generally worth fixing if the repair costs less than 50% of the price of a new machine and the appliance has been reliable until now. Because the average lifespan of a washer is 10 to 13 years, a reasonably priced repair can often buy you several more years of use.
