Nothing can be more frustrating than opening your dishwasher after a long day, only to find that it hasn’t done its job. If your dishwasher is experiencing issues, particularly with the water pump, it can leave you in a lurch. The water pump is a critical component responsible for circulating water during the wash and drain cycle. When it fails, the entire cleaning process is compromised. In this article, we’ll explore the common reasons why a dishwasher water pump might not be working and guide you through troubleshooting and repair options.
Understanding the Dishwasher Water Pump
The dishwasher water pump is designed to move water throughout the unit.
