What to do if your dishwasher overflows

What to do if your dishwasher overflows - If your dishwasher overflows during washing and rinsing, provide a small basin at the bottom. The water flows into the basin again, where the pump removes the water from the dishwasher. Depending on the type of dishwasher, the drain water can go directly into the pipe under your sink, or into the hose into your sink itself.

What to do if your dishwasher overflows

Basically, a dishwasher is a robot/machine that cleans and rinses dirty dishes. Humans have to load the dishes, add detergent, set the right wash cycle and turn it on, but the dishwasher completes a whole set of functions on its own.

Dishwasher function:

  1. Heating water to a suitable temperature
  2. Shoot the water through the jets to clear the dishes
  3. Air heater for drying dishes, if the user has selected that setting
  4. The heating element heats water to 130 to 140 degrees Fahrenheit.

A timer (or small computer) sets the length of each cycle. Sensors detect water and air temperatures to prevent the dishwasher from overheating or damaging your dishes.

Another sensor can tell if the water level is too high and activate the drying function to prevent the dishwasher from overflowing. Some dishwashers even have sensors that can detect dirty water coming from the dishes. 

Then a pump pushes the water all the way into the sprayed water, where it is forced out and sprayed onto dirty dishes. Think about a garden hose without a nozzle – if you put your thumb on the end of the hose, reducing the space for water to escape, the spray is more powerful. Dishwashers work on the same principle. The force of the water also makes the arm holding the spray jet rotate, like a lawn sprinkler.

The final step in the wash cycle is optional – the dry cycle. Some people let it dry without heat to save energy. Dishwashers are not very complicated mechanically.

The main parts of a dishwasher are:

The control mechanism is located in the door behind the control panel. Many units use a simple electro-mechanical system: a timer determines how long each part of the cycle lasts and activates the right function at the right time (such as the detergent dispenser, washing spray, and drying function). More expensive units may have a computerized control system. Modern units also have door latch that must be closed for the unit to work. Some also have child safety locks.

Inlet valve - This is where water from the home water supply enters the dishwasher. The unit pump does not pump water into the tub – when the inlet valve opens, water pressure pushes water into the unit.

Pump - An electric motor drives the pump. During the pump cycle, the pump pumps water into the spray arm. During the drain cycle, the pump directs water to the drain hose. The motor pump assembly is mounted under the basin, in the center of the dishwasher. 

Reversible This pump switches between pumping water into the spray and pumping water into the drain by reversing the direction of the motor. Reversible pumps are usually installed vertically.

Reversible pump - Direct Drive The motor runs in one direction, so the direction of flow is shifted from the spray sleeve to the line by a solenoid that opens and closes the appropriate valve or switches one hose connection to another. Non-reversible pumps are usually installed horizontally. Direct drive pump

The final word :

The dishwasher can be installed in a portable or permanent configuration. This portable unit is equipped with a side and top that can be used as a table. When not in use, the machine is placed next to a wall.

When it's time to run the cycle, the unit can be rolled up with casters to the sink, where it plugs into a faucet and plugs into a nearby outlet. In a permanent installation, the dishwasher runs under the counter and bolts in place. The hose under the kitchen sink connects directly to the hot water and drain lines, and this unit is usually attached to the sink as well. Both types of installation require 120 volt ground
