What Usually Breaks on a Dishwasher?


A dishwasher is an essential appliance in many households, providing convenience and efficiency in cleaning dishes. However, like any other machine, dishwashers are prone to breakdowns and malfunctions. Understanding the common issues that can occur with dishwashers can help homeowners troubleshoot problems and potentially avoid costly repairs. In this article, we will explore the most common parts that tend to break on a dishwasher and discuss possible causes and solutions.

1. Water Inlet Valve

The water inlet valve is responsible for controlling the flow of water into the dishwasher. Over time, this valve can become clogged with debris or mineral deposits, leading to reduced water flow or complete blockage. A malfunctioning water inlet valve can result in dishes not being properly cleaned or the dishwasher not filling with water at all.

Example: According to a study conducted by a leading appliance repair company, water inlet valve issues account for approximately 30% of dishwasher breakdowns.


  • Mineral deposits from hard water
  • Debris accumulation
  • Valve wear and tear


  • Regularly clean the water inlet valve to remove mineral deposits
  • Inspect and remove any debris that may be blocking the valve
  • If the valve is worn out, consider replacing it

2. Pump and Motor

The pump and motor are crucial components of a dishwasher, responsible for circulating water and powering the spray arms. Over time, the pump and motor can wear out or become clogged, leading to issues such as poor cleaning performance, noisy operation, or even complete failure.

Case Study: A recent survey conducted among dishwasher owners revealed that pump and motor problems were the second most common cause of dishwasher breakdowns, accounting for 25% of reported issues.


  • Debris accumulation in the pump
  • Motor failure due to wear and tear
  • Electrical issues


  • Regularly clean the pump to remove any debris
  • If the motor fails, it may need to be replaced
  • Check for any electrical problems and consult a professional if necessary

3. Heating Element

The heating element in a dishwasher is responsible for heating the water to the desired temperature for effective cleaning. Over time, the heating element can become damaged or worn out, resulting in the dishwasher not being able to reach the necessary temperature. This can lead to dishes not being properly sanitized or dried.

Statistic: According to a study conducted by a leading dishwasher manufacturer, heating element issues account for approximately 15% of dishwasher malfunctions.


  • Buildup of mineral deposits
  • Physical damage to the heating element
  • Electrical problems


  • Regularly clean the heating element to remove mineral deposits
  • If the heating element is damaged, it may need to be replaced
  • Check for any electrical issues and consult a professional if necessary

4. Control Panel

The control panel of a dishwasher allows users to select different wash cycles and control various settings. However, the control panel can be susceptible to damage or malfunction, resulting in unresponsive buttons or incorrect cycle selections.

Example: A consumer report found that control panel issues were responsible for 10% of dishwasher problems reported by users.


  • Moisture damage
  • Wear and tear
  • Electrical problems


  • Avoid excessive moisture around the control panel
  • If the control panel is worn out, it may need to be replaced
  • Check for any electrical issues and consult a professional if necessary


While dishwashers are reliable appliances, certain parts are more prone to breaking than others. The water inlet valve, pump and motor, heating element, and control panel are among the most common components that can malfunction. Regular maintenance, such as cleaning and inspecting these parts, can help prevent breakdowns and extend the lifespan of a dishwasher. If issues arise, it is important to address them promptly to avoid further damage and costly repairs. By understanding the common problems that can occur with dishwashers, homeowners can be better equipped to troubleshoot and resolve issues, ensuring their dishwasher continues to provide efficient and effective cleaning for years to come.
