Dishwasher Repair Unraveled

Dishwasher repair is a task most people are not familiar with. It can be a daunting task, especially if you know nothing about dishwasher parts or how they work


With all these parts staring at you, dishwasher repair can become a mystery that needs unraveling. In this article we will look at the steps it takes to repair your dishwasher, and maybe your neighbor’s, too, in the future.

Before you Start

Dishwasher repairs should always begin with two actions: First, make sure the dishwasher is unplugged, or trip the circuit breaker attached to your unit. Dishwashers run off of 115 volts or 120 volts. Dishwasher units are attached to your plumbing and electrical systems of a home. Second, shut off the water supply to your unit. The shutoff is usually located in the basement or crawl space under the home.

Operating Checklist

Dishwasher repairs have specific steps you need to take to diagnosis the problem and then complete the repairs.

i. Check the Power — If your dishwasher will not turn on, then you may have a power issue. Units that use a wall plug-in to receive power may have a problem with the cord or outlet. Check the cord for any tears or breaks. If the cord looks good, then check for blown fuses, the switch on the outlet, or circuit board problems.

ii. Disassemble the Dishwasher — The reason for this is you will need to gain access to the control panel of the unit. Since the control panel is located inside, you will first take off the front panel of the unit. You will need a few tools to complete this part of the operating checklist. Front panels are attached to the unit and the floor with set screws. These will have to be removed.

Possible Issues and Solutions

Dishwasher repair is all about finding the issue and creating a solution for it. Let’s take a look at a few possible issues and get the solution.

i. Door Gasket — The door gasket serves to keep the water inside the unit, not on your floor. It should feel soft and be resilient. If it feels dry or you see cracks, then replace it.

ii. Door Latch — The door latch tells the unit to turn on if the dishwasher knob is in the on position. If your latch is faulty, your unit will not turn on. A solution is to adjust the door latch. The alignment could be off due to the latch being loose or faulty.

iii. Switches — Problems in this area are associated with the door, float, timer, and control switches. To diagnosis these problems, you will have to test each one. Once a diagnosis has been made, then you may proceed by replacing the switch.
