So you face a need for a dishwasher repair.
Before calling in the professionals, do your best to diagnose and repair the problem on your own. Some issues are an easy fix if you know what to do and have the right tools.
Seriously, look at your dishwasher and consider where most of the parts are located. The control panel itself might seem a bit confusing. The board for it isn't something you will be able to repair if there is a technical failure. However, behind the door panel are some key parts which are easy to access, repair and replace. You also have inside the tub of the machine where you can access components like the drain and spinner arms.
Are you ready to troubleshoot your dishwasher problem? If so, make sure you have the right tools on hand before you begin. Most dishwasher troubles will require a multimeter to figure out, which is a device that's used to test for continuity and to see the amount of power that's present. You can refer to the owner manual of your dishwasher to determine what an appropriate result is and to see the wiring diagram so you know how to properly test each part of your dishwasher.
However, some issues are easy to fix without digging too deep. For instance, a problem with filling or draining might not be because of a switch or motor failing out. The issue could be due to a kink in a hose, a food-clogged drain and a few other superficial complications. Take the time to see what can be diagnosed at the surface, even if you aren't an appliance repair expert, because it just might save you an unneeded service call.
Are you washing plastic items in your dishwasher? If so, make sure that none of the plastic objects you wash include BPA. The high heat temperatures in a dishwasher can cause the BPA toxins to release from the plastic. Many plastic items are made BPA-free nowadays, especially baby bottles, but you can never be too safe. For instance, any plastic cup you purchase at Dollar Tree will only be safe to put in your dishwasher if it actually has a dishwasher-safe label. Check everything ahead of time; BPA exposure is a serious health concern that needs to be avoided.
