Where does the water in bottom of the dishwasher come from when not in use?

If a happy owner of a Bosch, Whirlpool, Maytag, Kenmore, Samsung brand dishwasher once encounters water at the bottom, it is probably the reasons that will be discussed later.

Inlet valve for water

It may leak water even when turned off due to calcium deposits in the valve solenoid. All this leads to jamming of the system. This phenomenon is often found in areas where water of increased hardness flows from the tap.

Inlet valve for water

In this case, you should not wait until the device floods the entire floor. It is necessary to replace the water supply valve and do it as soon as possible. There is no way to fix the situation for a while, a complete replacement is required. First you need to turn off the tap under the sink, and then understand what model number the unit has. Usually such information is located on the side. Based on it, it will not be difficult to find the right part.

To replace the intake valve, you must:

  • remove the plate located below;
  • see the hose on the left, it is connected to the inlet valve.

Each device involves its own assembly and disassembly activities.

Check valve

Its main task is to maintain an optimal level of pressure and prevent dirty water from the sink from entering the system. This element works only in one direction, and if it is damaged, the water props up. It is located in the drain hose after the connection to the pump.

It is this hose that will need to be disconnected in order to look inside the system and make sure that the check valve is not clogged. After all, toothpicks, nut shells, bones from meat can get into it. You also need to make sure that there is no damage to the valve.

Some models of Bosch and Samsung devices provide access to the check valve inside the tank. Correcting this situation is not difficult. All that is required is to remove the fine filter.

Position a drain hose

Position a drain hose under the sink

When it is in this position, the risk of dirty water running out of the sink increases every time it is used. For this reason, the system must be higher than the level of domestic plumbing, more precisely, more than 10 inches in height. The name of this item is the High Loop Drain Hose. This action ensures the prevention of water penetration into the system.
