Most common way to repair the dishwasher is by yourself. While it may seem like an intimidating appliance, a dishwasher is, at its heart, a simple device that you can repair on your own. Understanding how your dishwasher works will help you repair the machine smoothly and safely. Your dishwasher heats water as high as 140 F in its lower basin (the area below the bottom rack) with a metal heating element.
For repairs that involve removing the dishwasher from its bay, follow the safety shut-down and removal procedures. Dishwashers are top-heavy when the door is open and the machine’s mounts are removed.
Here are some of the most common issues to give you a better understanding:
Dishwasher is overflowing
Located in the dishwasher basin, the float assembly is a saucer-shaped device that rises as water rises in the basin. When the water reaches a certain height, the attached overfill float switch signals the dishwasher to cut off the water. If the float is not moving or switch not working, the water will keep rising until it overflows.
Dishwasher door is leaking
If water is dripping from the bottom or sides of your dishwasher door, most likely your door seal is no longer functioning properly and needs to be replaced. Your door may leak even though the machine is working well or it may be leaking in conjunction with overflow problems.
The dishwashers not draining
When the dishwasher does not drain or drains slowly, your machine probably has a blockage that you can clear by hand.
The dishwashers not cleaning well enough
It can be frustrating to run your dishwasher on a full cycle, only to discover dried, caked-on food after the drying cycle. Is your machine on the way out? Maybe not. For machines that aren’t cleaning dishes well.
The dishwashers not drying the dishes
Are the dishes still wet or damp even after a full cycle? That metal horseshoe-shaped heating element at the bottom of the machine, in the basin, is in charge of drying operations. This heating element is relatively inexpensive and is simple to replace.
Safe shut-down and removal procedures for the dishwasher
For all repairs that involve removing the machine from its location, follow these procedures:
- Turn off the circuit breaker at the service panel.
- Under the kitchen sink, shut off the water supply line. Disconnect the dishwasher drain and supply lines. Disconnect the power cord.
- Open the door. Unscrew the machine where it is attached to its metal frame.
- Open the door slightly to gain a hand-hold on the machine. Hold both sides of the door. Gently wiggle the machine side to side while pulling towards you.
- Do not open the door with the machine out of its bay as it can tip forward and injure you. Push halfway into the bay to prevent the machine from tipping.
