The dishwasher washes dishes using water spray and detergent. This work is performed in a completely sealed container. Also, water enters into one side, and dirty water is drained from another side. So, the causes and different parts can play roles in the water leaking of the dishwasher. In this context, we check and explain different parts which can be the leakage factor of the dishwasher. We recommend that you stay with us until the end of this useful post from the RepairLand website.
The water leaking from dishwasher can be very annoying and worrying. Even if leaking is a little, it may damage to floor coverings and walls. So, it will cost you a lot of money to be reconstructed.
Investigating the reasons for dishwasher leaking and how to fix the problem
In the following, we well-mention the list of the most common parts and components of a dishwasher can be the reason for water leaking under it. Also, we will talk about the mechanisms available to solve the problems related to it.
The water pump of the dishwasher
A defective pump/clamp gasket can be the main cause of water leaking under a dishwasher. The performance of the pump is to circulate water inside the system. In some models, it also drains water from the machine. The pump is installed at the bottom of the dishwasher. This part can have two parts including the water circulation part and drainage part.
Pump mold housing usually has a rubber band (washer) attached to a lower body of the dishwasher and causes it to be clamped and sealed. The life of the machine and that of detergents can cause the washer to be dried, crack, and be torn, as well as create water leaking. Separate parts of water circulation and pump water drainage also have clamp gaskets and seals to prevent leaking and seeping. Of course, these rubber components can also be cleaned due to abrasion and other factors and be the reason for water leaking from under the dishwasher.
Leaks and runoff resulting from these points usually are not considerable, and you must separate the access panel in front of the machine at the bottom of it.
The rubber gasket around the door
If it seems that water is leaking from the front of the machine, the problem may be related to the rubber gasket around the door. The door clamp or door gasket of the dishwasher is usually made of vinyl or soft rubber and located around of the dishwasher door. It creates a complete sealing environment. When rubber or vinyl is getting old, its flexibility is decreasing and even becoming brittle. So, it can damage easily and be destroyed. Thus, it will not seal the machine properly. Check the rubber gaskets around the door; if they have damaged, and been destroyed, replace them. Moreover, make sure that the washer is appropriately placed inside the grooves around the door so that there is not any gap between them. Also, make sure that a toggle door lock is intact and has been properly adjusted.
A dishwasher water inlet valve
The water inlet valve is the water supply duct of the machine, and maybe the reason for water leaking of your dishwasher from this area. The inlet valve can be found at the bottom of the back of the machine in several models. Water requirements are supplied by metal pipes and plastic/metal hoses attached to the inlet valve. Check connections of the mentioned hoses to the machine, make sure that they are connected properly, and there are not any cracks or cuts to create a leak. The problem may be related to the plastic body of the valve. So, it must be replaced. It is better to do these inspections when the dishwasher is filling up with water.
The detergent container
The detergent container and auxiliary detergent container (tablet, etc.) are usually located on the front door of the dishwasher. In some models, a set of containers has been used and connected to the panel with bolts. They use a washer for sealing and preventing leaking. Other models have the containers located on the panel and connected to the back of the front panel with pipes. They use rubber gaskets to seal the whole detergent container. If water leaking of your dishwasher is from the front of the machine, it may be due to the washer around the detergent container or its locking latch.
A sprinkler or water spray arm
Water (as well as detergent) is sprayed onto the dishes through movable water spray arms inside the dishwasher. All dishwashers have a water spray arm or sprinkler at the bottom of the machine, and some newer dishwashers have other water spray arms in the middle, below the upper tray or top of the machine. Many water spray arms are made of plastic. So, the spray pattern can thoroughly change if they crack or twist. The base part of metal arms can also damage, and the spray pattern can change.
These situations can cause water to divert down the door where a sealing washer does not exist. Thus, they will lead to a leak. Also, the blocked pores over water spray arms cause water direction to change and the mentioned problems to be created. Open and take out the water spray arms to inspect and remove any obstructions. Then, after making sure that they are intact, reinstall them.
The float and dishwasher’s float switch
The float and dishwasher’s float switch have been located as safety components to prevent the dishwasher from overfilling. The float is located inside the dishwasher at the bottom of it, and the switch is located at the bottom of the float. When the water rises in the dishwasher, and the water level reaches the proper level, the float causes the float switch to activate and closes the water inlet valve. A fault in the float or float switch of the dishwasher causes the water level to rise so high and a leak to be created. The proper water level is usually up to the heating element located at the bottom of the machine. If the water level inside of the machine is over this value, the float or float switch may be faulty. So, they must be replaced.
Hoses and hose clamps
Hose clamps strengthen the drainage hose and water circulation hose of the dishwasher pump. These hoses and their clamps are placed at the bottom of the machine under the protective plate. If the hose clamps are loose or hoses themselves crack, leaking can occur. Remember to check the existing clamps and tighten/replace them, if necessary.
