The structural design and form of the dishwasher haven’t changed in the past few decades, but its main components and operations still remain simple nonetheless. The many buttons and dials on a dishwasher’s control panel may seem intimidating, but its mechanisms are very straightforward that do-it-yourself dishwasher repairs are still possible.
In order to fix mechanical problems that hinder your dishwasher from operating properly, it is important to first familiarize yourself with the main parts of a dishwasher. It is through proper identification and careful assessment that leads to a hassle free DIY dishwasher repair.
What happens inside a dishwasher?
The main function of a dishwasher is to clean and rinse dirty dishes. It is not a necessity for most households, but for those leading busy and hectic schedules it is but an indispensable piece of kitchen appliance. It is commonly installed under kitchen counters and is powered by electricity. There are numerous brands that carry their own dishwasher product line. Some of the most famous dishwasher brands are:
- Kitchen Aid
- Fisher & Paykel
The major operation of the dishwasher is to combine and heat the mild detergent and water. Once heated at the right temperature, the motor sprays the mixture against the dirty dishes. Once the washing cycle is done, the motor pumps out the dirty water and then continues rinsing dishes with clean water which is sometimes added with a special rinsing agent. After the rinsing cycle, the dishes are then heated and dried. A thermostat ensures that the temperature inside the dishwasher does not go beyond the ideal level.
The main components of a dishwasher are listed below. They are also known to encounter problems from time to time. There really is no need to replace a dishwasher when one of its components breaks down. Dishwasher manufacturers and hardware shops sell spare parts for easy and inexpensive replacement. In order to do this, all you need is a basic understanding of the parts and their primary functions. The diagnosis of problems is easy too as symptoms directly point to two or more dishwasher components only.

Reviewer: David Francis -
Looked up google and read about Ameripro and called them to fix my dishwasher. I had tried to trouble shoot and replace some parts but that did not fix it. The technician came in, was very professional, zoned into the issue, fixed it and the washer was up and running. Liked the fact that he did not try and push for replacing a bunch of parts. Came back again a few weeks later when I started having same issue and tweaked the fix and did not charge me for the second trip!!!
