If you have a restaurant or a home with many people, you need to clean the dishes. When the dishwasher is broken, it means trouble for you. Unfortunately, just like any other appliance, the dishwasher develops a wide range of problems that prevent it from working as well as it’s supposed to. The most common problems as given by commercial dishwasher repairs professionals include:
Failure of the unit to clean the dishes
A dishwasher that isn’t cleaning the dishes isn’t a dishwasher at all. The unit will fail to clean the dishes due to many reasons such as:
A lot of debris on the dishes: If the dishes are too dirty, the dishwasher might not be able to clean them properly. For you to ensure that the unit is functioning optimally, you need to avoid putting the dishes in the dishwasher while they are still caked with food.
The best way out is to pre-wash the dishes. This way you remove the food scraps that might be hard to dissolve in the dishwasher.
Low water temperature: Just like when you are cleaning the dishes with your hands, water that isn’t hot enough might not clean the dishes effectively. When you notice that your unit isn’t cleaning the dishes as well as you would want it to, you should check the water temperature.
The ideal temperature to clean the dishes is between 120 degrees Fahrenheit and 150 degrees Fahrenheit. If the temperature isn’t within this range, adjust it.
Wrong detergent: Your dishwasher will also fail to clean the dishes properly when you are using the wrong detergent. You should always use high-quality detergents. If you aren’t sure of the right detergent that you should use, check the manufacturing manual for guidance.
Insufficient water: Finally, your unit won’t clean the dish as well as it’s supposed to due to insufficient water in the dishwasher. The best way to tell whether the dishwasher is getting enough water is to start a wash cycle then open the door when you hear the machine stop filling with water.
The water should reach the heating coil. If it doesn’t, inspect the unit. Confirm that the float valve is operating freely and the inlet valve isn’t clogged.
It’s common for the dishwasher to make some noise, but it shouldn’t be excessive. If your once quiet dishwasher is making a lot of noise, you have a problem in your hands that you should address.
Your dishwasher can make noises due to many reasons. The most common one is due to a defective pump. In some cases, the unit might be requiring you to replace the wash arm seal or bearing ring. Appliance repair professionals report that your spray arms might not be turning properly where they might be hitting the racks or dishes. In such a case, you need to replace them.
Failure of the dishwasher to drain
After cleaning the dishes, the dishwasher should drain the used water. If it’s not draining, you have a problem on your hands that you should keep an eye on. A dishwasher that is still full of water due to its failure to drain can hold the dishes hostage, causing flooding in the kitchen.
There are a number of things that can prevent the dishwasher from draining as well as it’s supposed to. The obvious one is a faulty valve in the drain pump. If the valve isn’t moving properly, you should replace it. Also, consider updating the drain pump or motor.
Also, remember to take a look at the obstructions for the solenoid and drain flapper.
Bad smell coming from the dishwasher
A properly maintained dishwasher shouldn’t produce any smells. If you have weird smells after the dishwasher is done, you most likely have trapped food and grease. This is usually located in the strainer screen and in the jets in the sprayer arms, along the bottom edge of the door.
For you to fix the problem, commercial kitchen appliance repair Springfield professionals recommend that you clean the affected areas then run a full cycle without the dishes. When running the cycle, remember to add dishwasher cleaner and disinfectant.
