This article will highlight what causes dishwashers to leak and some possible ways you can fix the problem.
What are the Causes of Leaking Dishwashers?
The possibility of your dishwasher leaking can be overwhelming. Allow us to simplify it for you by highlighting some of the most common issues causing that leak.
Over Filling the Dishwasher
In most cases, when the dishwasher is overfilled, it will use more water than it is draining. This forces water out. You can avoid this by washing only the right amount of dishes at a time.
Choosing the best dishwasher for your kitchen can help you avoid this mess. Countertop dishwashers are ideal for a small or less demanding kitchen. On the other hand, double drawer dishwashers are designed to handle more dishes at once and are suitable for bigger kitchens.
A Broken Water Pump System
A broken water pump leads to water leaking from the bottom of the dishwasher. It helps pump water as the dishwasher cleans the utensils and empties the water from the drain.
There are Hoses attached with clamps attached to the pump system. If they break, the dishwasher will leak tremendously at the bottom.
Leakage From the Door Seal
If your dishwasher is leaking, the door seal might be the problem. It could be damaged or worn out. Open the dishwasher door and inspect it for any damages.
A dirty door could also mean that it will not close properly. Please make sure the door is clean and closes as it should.
A Clogged Dishwasher Fitter
Food and foreign objects pile up over time when the filter is not cleaned often. This prevents water from going through, and aside from leaking, your dishes will not be properly cleaned. Always check to see if your filter is clogged up.
A Leaking Dishwasher Tub
This is a perfect example of what causes dishwashers to leak, especially if your dishwasher is old or handles big loads often. Due to wear and tear, the dishwasher might have developed a hole allowing water through. Water will collect under the dishwasher.
Depending on how old the dishwasher is and the extent of the problem, you might consider replacing your dishwasher.
An Improperly Aligned Dishwasher
Your dishwasher needs to be aligned to avoid water from accumulating at the bottom and leaking. Place shims under the unit and adjust until your dishwasher is perfectly leveled.
A Malfunctioning Float Switch
The float switch of a dishwasher determines when the dishwasher has enough water.
When the float switch is bad, water will keep on filling even after there is enough. It is advised to replace it when it malfunctions.
Using the Wrong Dishwasher Detergent
Only use the correct dishwashing detergent to avoid excess foaming. This causes pressure against the door seal leading to leakage. Using dish soap when rinsing the utensils is not advised.
A Few Ways to Fix Leaking Dishwashers
Identify the Source of the Leak
- Check where the leak is coming from. Most leaks come from around the door, but some also from the bottom of the unit. Leakage from around or under the door could mean that the float switch, gasket or spray arm are malfunctioning.
- Remove the access panel located at the bottom of the dishwasher and check the pump, inlet, hoses and motor. Using a flashlight, check all these components to see if they are faulty. You may identify the leak, especially if the dishwasher is leaking from the bottom.
- Do a thorough inspection of your dishwasher to find out what may be causing your dishwasher to leak.
Replace the Pump System
- Cut off power to the dishwasher by shutting off the switch and unplugging it from the socket. This is to avoid getting shocked as you replace the pump. Turn off its water supply as well.
- Detach the dishwasher from its cabinet using a screwdriver and remove the old pump. Install the new pump and reconnect the dishwasher to its water and power supply.
Fix All the Leaky Components
- The spray arm might be damaged or clogged. You can clean out a clogged spray arm, but it needs replacing if it is damaged. Always make sure the spray arms are firmly tightened.
- Replace leaky inlet valves. A faulty or damaged valve may lead to leakage.
- Change the float switch height to a higher position. This will change the water level in the dishwasher.
- To avoid leaking from a torn hose, you need to replace it with a new one, ensuring the clamps are tight enough. If the issue is loose clamps, tighten them firmly at the point where the dishwasher is leaking from.
- If your dishwasher is leaking from around the door panel, the door is not sealing correctly. This could be because it is worn out. It would be best to replace the door seal panel to ensure a tight seal against water in the dishwasher.
Unclog the Filter
- A clogged filter can cause a big mess on the floor. The good thing is that it is easy to fix. Clean out any solid residue from the filter to stop water from leaking on the floor. One should check the filter after dishwashing to ensure it is not clogged for the next wash.
Be it a double drawer or a countertop dishwasher; you can try some of these steps to see if the dishwasher will stop leaking. If the problem persists, always call a professional to avoid further damage.
