How To Diagnose Dishwasher Issues.

diagnose dishwasher problems

Dishwashers are vital kitchen appliances that facilitate the cleaning of dishes. Even with their small size, dishwashers easily compare to other home appliances and sometimes have attributes that beat any other appliance. They are spacious, easy to use, and have a pretty long lifespan. Attributes that make them one of the most convenient appliances in our homes. When one buys a brand new dishwasher, it is always with a smile on the face and the satisfaction that he won’t be scrubbing dirty pots anymore for a long time. Unfortunately, the truth is that things do not always go the way we plan when it comes to dishwashers. Your dishwasher might surprise you with a failure much earlier than you expected. In many cases, these failures even go unnoticed for a long time, and we only realize it is there the day our appliance ultimately gives up. That is why as the owner of a dishwasher, you should regularly have a look at your dishwasher and check that everything is working fine. To help you with this task, we decided to tell you what types of issues your dishwasher can face and how to diagnose dishwasher problems. 

Common Dishwasher Issues And How To Diagnose Them.


Error Codes

Dishwashers with a display often show error codes when there is a problem. These error codes correspond to specific failures in your appliance. Depending on the appliance you have in your appliance, the error code will point out a specific problem that you will have to fix as soon as possible. To detect, understand and solve an error code that appears on your dishwasher’s display, type the code on a search engine with the brand and model of your appliance. Then read carefully what the problem is and how you can solve it. Some of these issues are easy to fix DIY, while others require the trained hands of an expert appliance repair technician.

Drain Line Issues

Drain line issues are some of the most complicated issues to detect in a dishwasher. Dirty dishes after a cleaning cycle are one of the signs that shows that you have a drain line issue. If your dishes come out dirty after a cleaning cycle, check the high loop underneath your sink. The lack of a high loop causes water to go back into your dishwasher during the washing cycle. Thus, your dishwasher can’t clean up your dishes effectively. Call an expert technician to look at your sink and your drain line and to fix this problem.

Lack Of Water And Poor Water Pressure

The main element that a dishwasher uses to clean your dishes is water. If your washer does not get enough water or get it with low pressure, it can’t perform its task correctly. To find the problem with dishwashers that do not fill with water, you have to look at the water inlet valve. Check that the water valve inlet is not broken or leaking. Also, look at the water line underneath your sink and make sure that it is not kinked. If any of these parts are defective and you can’t replace them yourself, call an expert technician to do the job for you.

Clogged drain line

If your dishwasher has difficulties draining or does not drain at all, it could be because of a clogged drain line. To solve this issue, open your garbage disposal and check that it is clean and clear of any debris. In case your garbage disposal has some debris that clogs it, thoroughly clean it and try to see if it solves your draining issue. If it does not help, call a specialist to look at your dishwasher and drain line.

Malfunctioning Drain Pump

A malfunctioning drain pump is a huge and complex problem to fix, even for some appliance repair experts. The drain plays an essential role in your dishwasher. It helps your dishwasher to wash, drain, and also for circulation. Fixing it DIY requires deep technical knowledge and the right tools. That is why it is best to allow a trained appliance repairman to take care of it himself. If your dishwasher does not drain properly, we highly recommend calling our appliance repair experts to fix it correctly in the shortest time.

Dirty Filter

A filter’s role in the dishwasher is to trap residues of food and prevent them from sticking on your plates during the cycle. When this filter accumulates dirt, it can’t perform this task anymore, and you end up with dirty plates at the end of the cycle. To prevent this from happening, you have to clean your dishwasher at least once every month. To clean it, first, remove the filter. It is found on the interior floor of your appliance. Then hold its handle and turn it clockwise to open it and pull it out. Use a bowl of water, vinegar, and baking soda to clean it in and out. Once everything is clean, place it back into your appliance. 


Now that you know how to diagnose dishwasher issues, you do not have to worry anymore when your appliance behaves strangely. Just remember that maintenance is always better than repair. Always perform maintenance on your appliances at least every half a year to ensure that they are working properly and to extend their lifespan.
