How A Dishwasher Is Installed
Installing a dishwasher is a simple process that requires an electrical power source, a hot water supply line, and a drain.
Electrical Connection
For a dishwasher to operate, it needs electrical power. A typical appliance cord can make the electric connection when plugged into a standard outlet, or by hard-wiring a cable that feeds into the appliance box at the rear of the appliance.
Water Supply Line
Dishwashers are connected to the hot water supply line only and include a heating element inside the dishwasher. The water entering the washer is typically around 120 degrees F but will be heated to over 155 degrees F to sanitize items in the dishwasher.
Drain
The dishwasher drain can be attached to the sink drain adjacent to the dishwasher or, if there is a garbage disposal, to the disposal drain. The drain from the dishwasher must be connected before the sink’s P-trap and must be positioned with a high loop under the sink to prevent potential backflow of water into the dishwasher as well as water siphoning out of the dishwasher during normal operation.
Reasons Why A Dishwasher Might Overflow
There are several issues associated with a dishwasher and one common one is overflow. Here we will look at why a dishwasher may malfunction in this manor.
Malfunctioning Float Assembly
The float assembly is the component that tells your dishwasher when to fill with water and when to stop. If this part is malfunctioning it could be signalling for more water even when the tub is full leading to water overflowing on your floor.
Worn Door Gasket
The door gasket or tub gasket prevents water from leaving the tub when full. If the gasket should become damaged or loose, water can leak out. A common cause of a bad gasket is excessive wear and tear from constant exposure to water and detergent which compromises the integrity of the watertight seal.
Blocked Drain
The dishwasher drain is connected to the sink drain under your kitchen sink. A clogged drain line can cause water to back up and overflow. The clog could be in the sink line or from too much food waste blocking the dishwasher drain. If a garbage disposal is also installed excess debris in the disposal could also cause backups. You will be aware of this condition when you see water backing up into the kitchen sink.
Leaking Inlet Valve
The valve is located on the water inlet hose at the back of the dishwasher. If the connection loosens or becomes damaged water can leak behind and under the dishwasher.
Preventative Measures
There are some simple steps you can take to prevent water overflow from your dishwasher. Here are a few to help you start your maintenance.
Powders Over Gels
Always choose powdered dishwashing detergent over gels because gels contain chlorine bleach. Bleach will destroy gaskets and seals meant to keep water inside your machine. Also, gel-type cleaners tend to leave behind spots and soapy residue.
Measure Accurately
Always read the manufacturer’s suggestions for the amount of detergent needed. Too much detergent can lead to excess suds and issues with draining. Premeasured tablets are likely your best option.
Clean The Filter
Any type of buildup on the filter is problematic. Be certain to keep your dishwasher clean and regularly run the self-cleaning cycle. Also, always remember to crack the dishwasher door to allow excess moisture to evaporate or you could be facing mold issues.
Watch For Soft Water
For homes with water softeners, there are additional concerns. Soft water creates extra sudsing activity which can cause your machine to overflow. Again, check your manual for extract amounts of detergent needed.
