Why Is My Dishwasher Shutting Off

In the hustle and bustle of our daily lives, our trusty dishwasher stands as a steadfast companion, tirelessly cleaning our dishes and utensils without complaint. So, when your dishwasher unexpectedly shuts off, it can be both frustrating and perplexing. This article aims to unravel the mystery behind this common household conundrum. We will explore the possible reasons behind your dishwasher’s unexpected shutdowns and provide you with practical solutions to get it back up and running efficiently.

Understanding the Basics

Power Supply Issues

One of the most common culprits behind a dishwasher shutting off is power supply problems.

Tripped Circuit Breaker

A tripped circuit breaker can disrupt the flow of electricity to your dishwasher.

Faulty Power Cord

A damaged or faulty power cord can also lead to power supply issues.


Dishwashers have built-in mechanisms to prevent overheating, and if they sense excessive heat, they may shut off.

Clogged Vents

Blocked or clogged vents can cause heat to build up inside the dishwasher, triggering a shutdown.

Water Supply and Drainage

Water Inlet Valve

The water inlet valve is responsible for allowing water into the dishwasher. If it malfunctions, the dishwasher may shut off due to a lack of water.

Drainage Problems

A clogged or obstructed drainage system can also force your dishwasher to shut down.

Sensor Malfunctions

Door Latch Sensor

The door latch sensor ensures that the dishwasher door is securely closed before it operates. A malfunctioning sensor can lead to unexpected shutdowns.

Float Switch

The float switch monitors the water level inside the dishwasher. If it detects an abnormal water level, it may shut off the dishwasher as a safety precaution.

Electronic Control Board

Faulty Control Panel

The control panel on your dishwasher is equipped with electronic components that can malfunction, causing the dishwasher to shut off unexpectedly.


In conclusion, a dishwasher shutting off can be attributed to various factors, including power supply issues, overheating, water supply and drainage problems, sensor malfunctions, and electronic control board failures. To resolve this issue, it is essential to identify the specific cause and take appropriate measures. Regular maintenance, cleaning, and professional repairs can help keep your dishwasher running smoothly.
