Tips for Troubleshooting Common Dishwasher Problems

Tips for Troubleshooting Common Dishwasher Problems

The dishwasher is one home appliance that’s often taken for granted until problems creep up that affect its normal operation. If yours is malfunctioning, you may be able to get it working properly again by troubleshooting common dishwasher problems. If these tips don’t work, it’s time to call an appliance repair expert.

No Lights, Sounds or Water Flow

First, open and shut the door to make sure it’s securely latched. Then check for a tripped circuit breaker in your home’s main electrical panel. If these fixes don’t work, have a repair specialist check for a bad thermal fuse, a faulty door switch or a bad main control board.

The Motor Hums, but the Appliance Won’t Start

You’ll need professional help to identify the source of this problem and get it fixed. The issue may be a jammed pump or motor, a faulty motor start relay or broken drive belt.

Noisy Operation

Check whether the spray arm is hitting a dirty dish that’s sitting too high in the rack. If there’s no obvious obstruction, an appliance technician can check whether a foreign object is lodged in the pump or motor gears, the circulation pump motor bearings are going bad, or the wash or drain impeller is cracked or broken.

Dishes Aren’t Coming out Clean

Simply cleaning any buildup of food debris inside the spray arm and on the drain screen located on the tub bottom may fix this issue. If there’s no improvement, call a pro to look for other possible causes, like a faulty timer motor, a bad selector switch or burned out heating element.

The Dishwasher Doesn’t Drain

Try cleaning out the drain basket on the bottom of the tub. If this doesn’t help, look for clogs or kinks in the drain hose running from the dishwasher to the sink drain. If you have a garbage disposal, clean the dishwasher drain hose fitting too. If the dishwasher still doesn’t drain, it’s time to get a professional diagnosis.
