Common Causes for a Leaky Dishwasher


A dishwasher is a convenient kitchen appliance that most people take for granted. When you notice a leak from a trusted brand, there’s something gone wrong. Dishwashers need regular maintenance and upkeep to continue running smoothly. If you have a leaking dishwasher, there are a few reasons for this anomaly. Many dishwasher problems can be repaired by cleaning the appliance properly or replacing some parts. We have identified several common dishwasher problems and how to solve them.

Damaged Hose Clamps

Hose clamps help secure the drain hose and circulating hose to the dishwasher pump. You can easily find these clamps and hoses by removing the kickplate at the bottom of the dishwasher. Leaking is caused by clamps being loose or hoses having cracks in them. You can tighten the clamps using a screwdriver or replace the hose clamp. Refitting and replacing the clamps is also necessary. Make sure you call a professional plumber for this part.

Defective tub

Old dishwashers are more likely to develop a worn-out tub. Detergents and minerals in the water are known to cause corrosion of the tub. A hole may have also developed in the tab causing water to leak. The good news is that repairing damaged tubs is possible. Other times, the best solution is to replace the entire tub altogether. Make sure to check whether the damage is extensive and make the right decision. You can call a professional plumber to help if the damage is extensive.

Dishes coming out dirty or covered with residue

Make sure you check everything to ensure you are not doing anything to cause the problem. For example, it is possible to overload the dishwasher or to have utensils restricting the spinning motion. However, if this is not a problem for you, check for blockages, debris, or grease in the door gasket and strain screen. You can also use a water softener or a detergent to help soften your water.

Dishwasher Overfilling

If your dishwasher is taking in more water than it should and not draining correctly, overflowing will occur. Overflow causes water out of your dishwasher and on to your floor. You can also be having problems with the drain itself. Your float valve may not be sealing water properly. Consult your owner’s manual or go to the manufacturer’s website and find out how to fix the problem. Once you experience water leakages, clean up the leak and ensure you dry out the area.

Doesn’t dry your dishes

This dishwasher’s heating element usually causes this problem. If you have a working heating element, check the thermostat. A malfunctioning high limit thermostat causes the heat to shut off before the dishes are thoroughly dry. You can find your high limit at the bottom of your dishwasher tub. Always use a multimeter to check the device. Remember to check your rinse aid dispenser. Make sure it is dispensing correctly. Without the rinse aid, your dishes will not dry out properly.

Faulty doors

A sign of a defective door is finding drips of water accumulating directly under the door. If this happens, the door latch is either loose or misaligned. Due to the frequent mechanical movement, the door becomes faulty. You can use a screwdriver and tighten loose screws on the latch. If the door seal is loose, an epoxy patch kit and screwdriver will do the trick. When a seal cannot be firmly secured, the best decision is to replace it.

Dishwasher door hinges can also be adjusted to fit in place securely.

Noisy dishwasher

Most dishwashers will come with some noise unless you have an ultra-quiet dishwasher. If your once quiet dishwasher is making a racket, this is a cause for concern. You could be having a defective pump or need to replace the wash arm seal. Another possibility is your spray arms are not turning correctly. And this is making the spray arms hit the racks or dishes, and they need replacing. Noisy dishwasher’s problems are solved by replacing worn-out parts.

Smelly dishwasher

Old and wet food is likely to be the cause of your smelly dishwasher. Ensure you look through the machine correctly for any meal. Clean your dishwasher’s screen located at the bottom of your machine. Most people are shocked at how dirty and disgusting the screen can become. If you notice a chemical smell from your dishwasher, a plastic plate or Tupperware may have melted onto the heating element. Make sure to load your dishwasher correctly and pre-rinse your dishwasher.

Start Problems

If your dishwasher doesn’t start, make sure to check the power sources. Check whether you have a blown fuse and ensure the outlet is not malfunctioning. You can unplug the dishwasher and plug it back. If your dishwasher’s latch isn’t closed, your dishwasher might not start.

Sometimes, you might hear your dishwasher trying to work but won’t run correctly. It means your motor is stuck. Try spinning the motor by hand and see whether it moves. Ensure you turn off the power first to avoid electrical shock.

Unleveled dishwasher

If you have a misaligned dishwasher, water is bound to leak. To avoid this problem, open your dishwasher and place a level inside on the bottom. What this does is ascertain whether your dishwasher is level or misaligned. If your dishwasher is not level, you need a screwdriver to remove the service panel. Pull out your dishwasher and make the necessary adjustments. Make sure to fit back the dishwasher and screw the fittings.

Wrong dishwasher detergent

Are you using regular dish soap? Regular dish soap is a big no-no, as it foams up too much, leading to leakages. You should only use detergents intended explicitly for dishwashers. It doesn’t matter if you are rinsing your dishes with soap before running them. The solution on the dishes is known to bubble up and put pressure against the door seals. Avoid using dishwasher soap when rinsing dishes to avoid leaking problems permanently.

Appliance issues can become a pain in the neck, especially if they persist. A dishwasher leak repair is not one of the favorite things to do. Troubleshooting the problem will save you time and money. If the problem persists, you can always depend on professional plumbers to come to your rescue.
