Dishwashers are a convenient appliance that can save you loads of time by not having to wash your dishes by hand. There are problems that commonly occur with this appliance, though. These issues are often the result of clogs, mineral deposits, malfunctioning parts, or issues with water flow. Knowing how to spot problems and fix them will help you protect your dishwasher and keep it functioning reliably and efficiently.

Dishes Not Getting Completely Clean

If you’re noticing food debris leftover on your dishes after running a wash cycle, there may be an issue with weak spray pressure. Not enough water is flowing through the unit to make use of the soap and get things clean. There may also be items in your dishwasher that are preventing the wash arm from moving.

Avoid overloading your dishwasher so water and soap can properly circulate through your appliance. You can also clean the spray arms and the inside of the unit to remove any mineral deposits or food buildup. If your unit has a filter, remove any built-up debris and wash it.

If you notice cloudy or white spots on your dishes, this is the result of hard mineral deposits. You can address this problem by using a water softener to remove minerals. A rinse aid that softens these minerals is also helpful.

Water Doesn’t Completely Drain

There shouldn’t be any leftover water inside your dishwasher when a cycle is complete. Standing water can indicate there’s a clog inside the drain of your unit. Inspect the drain hose for any clogs or kinks. Check the drain filter to see if there’s any material blocking water from flowing through.

Dishwasher Doesn’t Fill With Water

If you notice your dishwasher cycling but there isn’t any water entering the unit, there is likely a problem with your water supply line. Make sure the valve is open and the inlet valve screen is clear. The float switch should move and shouldn’t be stuck in a position that senses the dishwasher is full.

Abnormal Noises During Operation

When your dishwasher is running, it should be relatively quiet. If you notice any grinding, buzzing, or rattling sounds, there may be debris caught near an interior component. Worn parts may also be to blame. Make sure the spray arms are clear and move freely. A professional can replace worn bearings if they are the cause of the noise.

Foul Odors Coming From the Dishwasher

Odors generally are the result of food particles left inside your dishwasher. Periodically empty and wash the filter. Wipe out the inside of your dishwasher to remove any greasy films. You can also properly scrape your dishes before loading them into the dishwasher to prevent this from happening.
