What is the most common reason a dishwasher stops working?

As someone with extensive experience in plumbing, I’ve encountered numerous cases where dishwashers suddenly stop working. It can be quite frustrating, especially when faced with a pile of dirty dishes waiting to be cleaned. In this blog post, we will explore some common reasons why dishwashers malfunction and provide insights on how to troubleshoot these issues.

1. Clogged or Faulty Drainage System

One of the most prevalent reasons for dishwasher failure is a clogged or faulty drainage system. Over time, food particles, grease, and debris can accumulate in the dishwasher’s drain hose or filter, obstructing proper water flow. This can lead to standing water inside the machine and prevent it from functioning correctly. To resolve this issue, check the drain hose and remove any blockages manually.

2. Water Supply Issues

Another frequent problem that causes dishwashers to stop working is water supply issues. If there’s insufficient water entering the appliance during the wash cycle, it may fail to clean dishes adequately or even refuse to start altogether. Ensure that the water supply valve connected to your dishwasher is fully open and not blocked by any obstructions.

3. Malfunctioning Heating Element

Dishwashers rely on heating elements to heat up water during the washing process effectively. When these elements become defective or burnt out, your dishwasher may struggle to generate enough heat for proper cleaning and drying of dishes. If your dishes are wet after the cycle or if the water doesn’t get hot enough, it could mean that the heating element is broken and needs to be replaced.

4. Broken Door Latch

A broken door latch is another common culprit behind a malfunctioning dishwasher. The door latch mechanism ensures that the door remains securely closed during operation, allowing no water leakage and initiating the wash cycle properly. If your dishwasher fails to start or stops mid-cycle, it’s worth checking if the door latch is intact and functioning correctly.

5. Control Panel Issues

Sometimes, dishwashers may cease to work due to control panel malfunctions. If the buttons on your dishwasher’s control panel become unresponsive or erratic, it can be a sign of electrical problems. Try resetting the dishwasher by disconnecting its power source for a few minutes and then plugging it back in. If the issue persists, you might need professional assistance to repair or replace the control panel.


In conclusion, there are various reasons why your dishwasher might stop working. From clogged drainage systems to faulty heating elements, these issues can disrupt your daily routine and leave you with piles of dirty dishes. By understanding these common problems and implementing proper troubleshooting techniques, you can potentially save time and money on unnecessary repairs. Remember, when in doubt, always consult a qualified professional who can help diagnose and fix the issue promptly.
