Troubleshooting Common Dishwasher Problems; Doesn’t Clean Dishes, Leaks, Bad Odors, Loud Noises, Won’t Fill With Water & More

Having a problem with your dishwasher is horrible. Dishes can pile up quickly when a dishwasher is out of order. Every homeowner needs to do minor maintenance to their dishwasher just like with any other appliance. If you are having problems with your dishwasher, it may be a simple fix that you can easily take care of. Southwest Appliance Repair of San Antonio is here to point out some simple solutions to common problems homeowners face when it comes to their dishwasher.

Dishwasher Doesn’t Clean Dishes

If your dishes are coming out of the dishwasher looking less than stellar, then your dishwasher isn’t doing its job. The first thing you will want to check is the spray arms. Make sure they can move freely without hitting any dishes in the way. This will make it so the water isn’t evenly distributed, leaving some dishes unclean. You may want to try giving your dishwasher a good cleaning too. Make sure there isn’t any buildup making it difficult for the water pressure to be where it should be. This can be caused by hard water. If none of this works, it could be that your upper discharge housing gasket needs replacing or tightening.

Causes of Leaking Dishwasher

A dishwasher that is leaking can cause quite a bit of grief to any homeowner. It doesn’t take long for excess water leaking from your dishwasher to cause damage elsewhere. If you find your dishwasher leaking water, the first place to check is the drain. If there are any obstructions in the drain, the water will buildup and eventually start to leak because it can’t properly drain. Another problem might be the seal around the door of your dishwasher. Make sure there is no cracking or other damage on the seal, or it will need to be replaced. You can also check the hose for any damage that could cause it to leak. Leaking dishwashers can also be caused by a pump that needs replacing.

Dishwasher Has Bad Odors

Since your dishwasher is responsible for cleaning food off of dishes, it is only natural that food can get trapped in the drain occasionally. You should check the strainer screen for any food or grease that is sitting in there. Giving your dishwasher a good cleaning on a regular basis should help you avoid bad odors. If you rinse large pieces of food or grease off of dishes before placing them in the dishwasher, you can most likely avoid this problem as well.

Dishwasher Making Loud Noises

Dishwashers do make a certain amount of noise in order to operate, but if you notice your dishwasher is louder than normal, you may have a problem. Make sure there isn’t anything in the way of the spray arms. If they are hitting against any dishes, it can cause a loud knocking noise. It could mean a bigger problem with your pump that will have to be looked at by a professional.

Dishwasher Won’t Fill with Water

If your dishwasher isn’t getting the water it needs to work properly, it can ruin the dishwasher completely. The first thing you should check is the hot water supply stop valve under your kitchen sink. Make sure it is turned on and your dishwasher can get the water that it needs. Your water inlet valve could need replacing and that would be a bigger problem.
