What Causes A Dishwasher Not To Drain
You can handle many issues with the dishwasher on your own following instructions in the troubleshooting section of the manual. But the issues with the drain require detailed analysis. And the first thing to understand is the principle of a dishwasher operation.
The dishwasher operates similar to a washing machine. The only difference is that the water goes twice through the purification system. Each stage of the wash cycle is completed by water draining. If the dirty water is not removed, the machine cannot proceed to the next step of the program.
At first, there is a rough filtration, then a fine filtration follows. The average water consumption is 9-12 liters. Saving is achieved by constant purifying of the same water. After the filtering process, the water enters the pump, returns to the rocker arm and sprinklers.
At the end of the selected wash cycle, the water goes down and the drainage pump sends it to the sewer system. But it does not happen if any element of the drainage system does not function properly or is completely out of order.
So, why does the dishwasher stop and fail to drain the water? There can be different reasons for it:
- Filter clogging
- The fold of the hose through which the water is drained
- Clogged drain system
Change Or Clean The Filter
Its possible that a blocked dishwasher filter is stopping water from draining. Many households are unaware that dishwasher filters must be cleaned on a regular basis.
Keep a look at your dishwashers managers handbook. There youll find out where the pipe is situated or not. Figure out when and how to clean it.
The pipe for many dishwashers is located from the inside bottom of the dishwasher. Be careful about the leakage in the pipe joint.
