Dishwasher DIY Tips and Tricks July 2020

Repairing a Dishwasher

Repairing a dishwasher on your own saves you money and time. Instead of waiting around for a Maytag or Sears dishwasher repairman,

You can install the replacement parts by following the troubleshooting guide in your manufacturer’s owner’s manual. Before opening up the dishwasher cabinet,

Verify that the appliance is getting electrical power and hot water from the house. Make sure the dishwasher door latch is locked and the control panel on the front of the appliance is set correctly.

Dishwasher Repair Basics

A dishwasher’s electrical system depends on whether it is a portable unit or built into the kitchen cabinets. Portable dishwashers can be plugged directly into the wall outlet like any other small home appliance.

Built-in appliances must be wired into the home’s 115-volt or 120-volt electrical system directly. The water supply line connects to the home’s water heater to provide the dishwasher with the hot water it needs to sanitize your dishes.

Ideally, the water inside your dishwasher should be 140 degrees Fahrenheit.
