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.
Replacement Dishwasher Parts
Buy replacement dishwasher parts that are compatible with your appliance's make and model. If you are unsure which replacement part you need, remove the defective part from the dishwasher and take it with you to the appliance supply or hardware store. You may be able to find a list of replacement part numbers on the manufacturer's website if you have a Kenmore dishwasher or other major brand. Other websites also sell appliance parts direct to the customer.
Dishwasher Repair Safety Warnings
Before performing any home dishwasher repairs, make sure the power is shut off from the circuit breaker box. If you are repairing a portable dishwasher, you may be able to unplug the power cord from the electrial outlet instead. Shut off the water supply from the main valve under the sink before attempting any dishwasher repairs or maintenance.
