Dishwasher has become an unavoidable device in the modern kitchen. Home makers who get accustomed with the regular use of this device will find it difficult to carry on household chores easily if the machine breaks down suddenly. The time consuming hand washing of dishes is something the home makers wish to avoid. It is therefore important that dishwasher should be maintained properly to avoid unexpected breakdowns and preventive measures are to be undertaken as in the case of other household appliances.
One of the common problems that occur in the dishwasher is water flooding. There are any causes for occasional flooding especially when it is put to continuous use. Leak in the internal hose pipes can be a probable reason. At times loose clamps that secure the hose pipes will lead to leakage. Hot water circulation in the machine may be the reason for clamps getting loosened. The user may not be aware of such leaks while the machine is running. Sudden stoppage of the dishwasher will alert the user who can detect water stagnation at the base of the machine. It may not be possible for a layperson to detect the source of leakage or the cause for it. By pulling the machine forward and tilting it by 45 degrees, the accumulated water can be drained off. Once the base is emptied and stagnated water removed completely, the machine can be switched on again.
But the reason for leakage or flooding is to be investigated. The service department of the manufacturer or dealer will be able to fix the problem. There are possibilities for similar problems to occur again. All modern machines are provided with anti flooding devices to prevent such occurrences. It is known as anti flood safety system, which will detect water leakage and accumulation at the base of the machine.
The float switch provided for the purpose will activate the system. When the water level rises due to flooding, the float will push the switching mechanism. The programme device will receive alert signals and the pumping in of water will stop automatically. Float switch will also function as a water level indicator. On receiving signals the switch activate the drain pump and accumulated water will be pumped out.
Different methodologies are being adopted by manufacturers of dishwashers to prevent flooding. Many systems are invented and patented in this context. But such devices are based on identical principles. Inlet and outlet of water are monitored by sensors incorporated in the system. In case of flooding, supply of water will be regulated automatically and water collected at the base of the machine will be pumped out.
Anti-flood safety system is now incorporated in all popular brands and models of dishwashers. Intensive heat generated in the machine is a cause of worry and potential accidents. Scalding is a very common hazard occurring in the dishwashers. The consumers should take care to choose a quality product which is equipped with anti-flooding device. Apart from scalding there are possibilities of pipe bursts and short circuits. The users should therefore be careful in handling the machines. They should strictly follow the manufacturers’ instructions regarding the use and maintenance of the dishwashers.
