Commercial Dishwasher repair in Lower Mainland, BC.

Commercial dishwashers are essential tools in any commercial kitchen. They are designed to handle large volumes of dishes, glasses, and utensils, making it easier for kitchen staff to keep up with the pace of a busy restaurant. However, like any piece of equipment, commercial dishwashers can experience problems that can impact their efficiency and effectiveness.

Here are some of the most common problems that commercial dishwashers face, and some

recommendations for how to address them.

Problem 1: Poor cleaning results

If your dishes are coming out of the dishwasher dirty, it could be a sign that your dishwasher is not functioning properly. Poor cleaning results can be caused by a variety of issues, including clogged nozzles, a malfunctioning pump, or inadequate water temperature.


  • Check the dishwasher's water temperature. Make sure it is hot enough to sanitize dishes and remove food debris effectively. The ideal water temperature should be between 120-140°F.

  • Check for clogged nozzles or blocked spray arms. Clean any clogs or blockages to ensure that the water is reaching all surfaces of the dishes.

  • Check the pump for any signs of malfunction or wear and tear. If you notice any issues, replace the pump as soon as possible.

Problem 2: Leaking dishwasher

A leaking dishwasher can cause serious damage to your kitchen floor, walls, and equipment. It can also increase the risk of slips and falls for staff working in the area.


  • Check the door gasket for any signs of wear or damage. Replace the gasket if necessary.

  • Check the water inlet valve for any signs of damage or leaks. Replace the valve if necessary.

  • Check the drain hose for any signs of damage or blockages. Clear any blockages or replace the hose if necessary.

Problem 3: Noisy dishwasher

A noisy dishwasher can be a nuisance for both staff and customers. It can also indicate a potential problem with the dishwasher's motor or other components.


  • Check the dishwasher's motor for any signs of wear or damage. Replace the motor if necessary.

  • Check the dishwasher's pump for any signs of wear or damage. Replace the pump if necessary.

  • Make sure the dishwasher is properly leveled. A dishwasher that is not level can cause excess noise during operation.

Problem 4: Cloudy dishes

If your dishes are coming out of the dishwasher with a cloudy or hazy appearance, it could be a sign of poor water quality or detergent buildup.


  • Check the dishwasher's water quality. Poor water quality can cause mineral deposits to build up on dishes. Consider installing a water softener to improve the quality of the water.

  • Check the detergent you are using. Make sure it is designed for use in commercial dishwashers and that you are using the correct amount.

By following these recommendations, you can keep your commercial dishwasher running smoothly and efficiently. Regular maintenance and inspections can also help you catch potential problems early, before they turn into major issues. With proper care, your commercial dishwasher can provide reliable service for years to come.
