Reasons Why A Dishwasher Won't Drain?

"If your dishwasher wont drain, it can happen due to a variety of reasons."

Running a diagnostic check is what is called for before you run to call in the technician. Most reasons why a dishwasher wont drain are due to improper usage and handling of your dishwasher. While dishwashers are intelligent systems, it nevertheless needs to be properly taken care of, following certain basic principles. The most common reason for the dishwasher failing to drain water arises out of mineral build up in the filters and the drains. While highly sophisticated systems are equipped with sensors to detect the hardness or softness of water with appropriate responses to remedy the situation, an ordinary dishwasher will require some preventive care by way of water softening, if hard water is used.

Likewise, it has to be understood that the signal to drain is triggered by float valves and timers. A malfunction in either of these can cause draining problems with dishwashers. The severity and complexity of the factors resulting in slow draining dish washers needs to be ascertained by simple diagnostic tests. While repairing a defective float valve is a simple and inexpensive task, not knowing the real reason or failure to identify the process can lead to much expense and futile attempts at repairing. The key to understanding why your dishwasher wont drain is to understand how and when water is drained, and what triggers the draining process. While the actual flow of water is controlled through valves and filters, the when factor is determined by timers.

However, on occasion, a sophisticated computerized control which relies on information from sensors may shut down the drain cycle too early when fed information by defective sensors. In this case, it is the sensor that needs to be replaced or repaired and not the control panel.
