Guide to Troubleshooting Dishwasher Issues

Appliances

Unlike other household appliances, a dishwasher gives specific symptoms to indicate what is wrong with it. By identifying the problems with your dishwasher, you can save money by reducing repair times. You could even fix the simpler issues yourself. Follow the tips below to learn how to diagnose dishwasher problems on your own [source: WN].

If your dishwasher is leaking, it could be due to several reasons:

• Overloading: Overfilling the dishwasher could cause it to leak. Try reducing the number of dishes and see if the leak persists.
• Faulty Door Seal: Inspect the plastic seal around the door. If there are cracks or holes, it may cause the machine to leak. Replacing the seal is a simple and inexpensive fix.
• Excessive Detergent: Check the detergent tray. If there’s a soap residue left behind, it means too much soap is being used per load, leading to the machine leaking.
• Faulty Pipe Connections: Check the pipes at the back of the machine. Tighten any loose pipes to possibly stop your dishwasher from leaking.

If your dishes are still dirty and dry after washing, it means that your dishwasher isn’t filling with soap and water. It could be due to:

• The Hot Water Valve: Check under your sink to see if the hot water valve is fully open. Opening it will allow your dishwasher to fill with water.
• The Inlet Valve: If the valve is clogged with debris and residue, cleaning it will repair the machine and enable the dishwasher to fill.

A small amount of water at the bottom of your dishwasher is normal. But if there is an excessive amount of water, you may have a problem with the drain hose. Refer to your machine’s manual to find your dishwasher’s drain hose. Check that the drain hose has no holes, is not damaged, and is free of debris or soap residue [source: Home Serve].

If the problems with your dishwasher persist, call a professional to fix them.
