Most Common Reason For Dishwasher Overflow

​An overflowing dishwasher can be a severe problem if not correctly fixed. Finding a puddle of water on your floor is never a pleasant sight. Water damage on floors and rugs can be overly expensive if not fixed on time. Diagnosing the problem can help save your floor and your money.

There are several reasons why your dishwasher is overflowing with water and detergent. These problems mostly range from simple errors to faulty parts that need adjustment or replacement. Knowing what is causing an overflowing dishwasher will help diagnose and repair the problem.

Fortunately, with a little know-how, dishwasher repairs can be done at home. A great place to start is checking the dishwasher manual and online for additional tips and resources. Most dishwasher manufacturers have user-friendly websites packed with vital information. You can easily find a local retailer for parts or have an online chat with dishwasher experts. Below are some of the common reasons for dishwasher overflow.

Dish detergent

One of the most common reasons for dishwasher overflow is soapsuds. If you are using a weak detergent that is leaving more than half an inch of suds on top of the water, floods can happen. Additional small amounts of dishwasher liquid or hand soap can cause an overflow. Most users find themselves putting too much detergent or the wrong type of soap into the machine. You can add some vinegar into the appliance or use some of the best dishwasher detergents available.

Filling your dishwasher with too much detergent will cause overflow and having sudsy water. While some detergents are cheap, poor quality of the soap will cause you to rethink saving a couple of bucks.

Door Gasket

If soap suds or water escape past the dishwasher door onto the floor, you have a door gasket problem. The problem is your sealing gasket on the dishwasher door is most likely worn out and needs replacement. When a dishwasher closes, the rubber seal going the entire interior door is what makes sure the water remains inside. Once the door gasket gets brittle, ripped, or worn out, water will eventually overflow.

A good way to stop this is to clean the gasket and make sure to add some small amounts of petroleum jelly. If you find your door gasket is in bad condition, make sure to restore it, as replacement is generally the best way to repair this problem.

Improper alignment

Another problem that caused water overflow is dishwasher alignment. A dishwasher must be at a leveled surface, or else you will face the possibility of water gathering your unit is highly likely. You need to place a level at the bottom of your dishwasher. If you have a misaligned dishwasher, make sure to set some shims under the unit and measure it again. Adjust your dishwasher until you’ve perfectly leveled it.

Water Inlet Valve malfunction

A dishwasher supplies water from the water inlet valve. If the valve is working correctly, it provides a dishwasher with a proper quantity of water and then shuts off. When the bottom of the dishwasher fills with water, the inlet valve is malfunctioning. If the valve is faulty, the appliance will fill the water and overflow onto the floor. Check the water inlet valve which is usually found under the dishwasher and connected to the water line coming from under the sink.

Overfilled dishwasher

Did you know your appliance may be taking in more water than it should? Not draining the excessive water will force water out of your dishwasher. Users are, at times, experiencing problems with the drain itself or not having a properly sealed valve. Depending on the type of dishwasher you have, you should consult the owner’s manual or manufacturer’s websites.

Float Assembly is faulty or stuck

When water enters the dishwasher, the float assembly will automatically move upwards. The float assembly tells the dishwasher water valve when to shut off the water. Once the float is stuck on the UP Position, dishwashers will overfill. Make sure to check the float assembly to find out whether the float is stuck. A float assembly switch is on the inside bottom of the dishwasher.

Loose of damaged valves

Over time, connections and hoses inside your dishwasher can get free. Make sure to check your drain hoses and ensure everything is securely connected. Check whether the clamp holdings are in place on either side. Also, verify whether your water inlet valve isn’t stuck, which may cause flooding. Cracked hoses are easy to replace with a trip to the hardware store.

Leaky dishwasher tub

Your dishwasher has seen its fair share of loads, and leaks may have developed from a hole in the tub. Most detergents and minerals can corrode the bottom of your tub, causing water to seep through. This water collects under your dishwasher and tubs can be replaced depending on the severity of the damage.

Bottom of the dishwasher being blocked or clogged

The bottom of the dishwasher can, at times, fill with food particles. These foods can prevent or clog the area where water drains out. If water cannot drain out of the dishwasher, water will eventually overflow upwards and will leak out of the door. To avoid such blockages, make sure to clear the bottom of your dishwasher after use. Make sure to keep the filter clean and always check for any broken glasses. Keeping a clean dishwasher will prolong its use and help run it as designed by the manufacturer.

Dishwasher tips to remember

If you are having problems with water leaks around the base, cut back on the amount of detergent used. Improperly loaded dishes can cause water to spill through the water vents. If your dishwasher is overflowing or leaking, contact your nearest appliance repair.

Appliance issues can be a pain in the neck, and repairing a dishwasher is no exception. Patiently troubleshooting dishwasher problems can save you money and time. If you experience water leaks, properly clean up leaks and ensure you dry out the area. Don’t allow your floor to become damp as hazardous mold spores can proliferate.
