Dishwashers
Dishwashers
Dishwashers are electromechanical household appliances used for cleaning and drying of dirty utensils and dishes. Dishwashers are also used in restaurants but they are high capacity heavy duty machines specially designed to take large quantities of dishes every cycle.
Characteristics of Dishwashers
Capacity: Typically, like any other home appliance, dishwashers are categorized by their capacities, broadly speaking. This means that the capacities rule the roost when it comes to choosing dishwashers. Let us say dishwashers are not suitable for irregular shaped dishes and utensils despite them being sufficiently large in size, so they depend more on the place setting or rather in layman's language, organization of wash racks within the washing cabinet to receive maximum dishes and utensils. Another point you will need to check when inspecting dishwashers to buy is whether they are suitable for most of the utensils you want to use the dishwasher for.
Size: Size is another critical factor that differentiates dishwashers. It is also an important factor for decision making because the size of the machine affects your location to install it and more importantly cost of ownership.
You can expect a certain degree of standardization of dishwashers in terms of their sizes even across different brands. The regular size for dishwashers is 60CM in width and 86CM in height in Europe whereas in America, the sizes are expressed in inches; however they are more or less the same, if you are thinking of buying one from America for your kitchen. Nevertheless, washtub decides how much space you can actually utilize within the machine. A tall tub design provides extra 20% space than a standard design tub which have a service kickplate underneath their doors. You can also consider portable dishwashers which come fitted with counter tops and castor wheels. Their sizes are conveniently built in 45W and 60H CM.
Silencing or Damping of Sound: Modern dishwashers dampen sound to quieter 40-45 decibels using a combination of sound absorption materials, blankets or panels etc unlike their predecessors. Remember, all these things cost a little premium to you. However, undampened models are known to producing of upto 70 decibels.
Types of Dishwashers
Types of dishwashers are the important points that play their roles in decision making. Basically there are three types of dishwashers available throughout Europe.
Free standing type of dishwashers: This is the most simplest of the designs in all the types of dishwashers but they are bulky in size occupying lots of floor space thus are suitable more for large restaurants. Since there are countless dishes and cutleries are to be washed in a restaurant environment these free standing dishwashers are built robust for continuous operation. But as it goes, free standing dishwashers, although flexible, their front stays visible even after installation. These are cheapest of all the types, despite their large capacities, for obvious reasons.
Built-In Dishwashers: As the name indicates, these built-in dishwashers have their control panels built in such a manner that they are hidden in the top of the door. The entire built in dishwasher is so convenient that the entire unit can be installed with in the kitchen no matter even if it the full height model.
Advantage with built in dishwashers is they take less time to install and are relatively cheaper. Don't get confused with terminologies like fully integrated dishwashers or integrated dishwashers as they all are referring to the same old built in dishwashers.
Semi Built-In Dishwashers
Semi built-in dishwashers are suitable for a drawer line kitchen and will be covered by a matching door to the full height. Alternatively, a matching door-panel can be may also be used. Thanks to their build at a convenient chest height, loading and unloading are easy so.
If you are concerned about kitchen space, under-counter dishwashers are the things for you. They can handle upto 30 racks of dishes every hour thanks to their quick heaters. They are usually available in stainless steel construction for long life and ease of cleaning.
Features of Dishwashers
First of all, dishwashers, regardless of their types need to be long lasting and rugged for handling various dishes. Secondly, buyers are also interested in the dishwashers' power and water consumption levels ahead of knowing the level of automation.
Most dishwashers have their tubs built in stainless steel to weather mechanical deformation and chemical erosion unlike in the past when the tubs were made in plastic. Stainless steel helps dampen sound to a great extent and retain heat by reflection thus effecting faster drying of utensils. Another drawback of plastic tubs or hard enamel lined steel tubs is chipping out with usage before giving in finally. Repairing the enamel lined tubs is expensive.
Hard food or food leftover disposers are almost a standard feature in modern kitchen dishwashers; however, Baush avoids this feature in order to contain noise level. Another idea behind avoiding this is tucked on to water consumption which increases with pre-rinsing cycle done to remove hard and large food leftovers under running water. If they can be cleared by hand before loading the dishes it saves a lot of water even with mini garbage removal units fitted on.
Most automated features such as wash cycles and drying cycles, temperature and water flow control are through microprocessor control units. Electromechanical rotary switches are replaced by photoelectric sensors to trigger or switch off sequenced operations.
Damping is a critical feature in most kitchen dishwasher brands. Some manufacturers have their own specifications and registered nomenclatures for this feature (such as whisper package or Quiet Guard etc) however the bearable decibel level should be around 45 to be suitable for long operations over the years.
Child lock is another optional feature you may like to have; direction of water feed may differ in certain brands but this may not be considered as a unique feature.
Dishwasher Accessories
There is a whole host of accessories if you are keen to buy and they start selling from as low as $2.25 for a kit of dishwasher rack repair tine pins to the biggie – dishwasher door panel which costs anywhere above $300 depending upon the size and make of your dishwasher. And there are some accessories that are sold only along with a dishwasher, such as dishwasher tip guard which are very useful in securing the machine when it is hardly possible to attach it to counter top or cabinet.
However, out of all the dishwasher accessories what you might find of utility are dishwasher top fill strip for around $40, heavy duty door spring set, and space maker, either in single or double bowl which costs around $180, in stainless steel. Heavy duty door spring sets are really of high utility value especially if you are using it on a continuous basis. It may not cost you not more than $19 or 20 but the peace of mind it provides is very high.
Additional stainless steel top dish rack is another one you might find useful. This comes across as a replacement for even the new one especially if it is hard enamel coated. Hard enamel coated dish rack is good till it does not begin shedding. So also, large knife racks are pretty handy if you are frequently using long handled utensils or knives. Storing them over this knife rack is safe for racks to prevent chipping.
Of all the things, you probably can't do without the pair of dishwasher cleaner and dishwasher garbage disposer. These two things are designed particularly to keep the machine healthy and spic and clean. The garbage disposer is particularly designed for continuous operation, so you can fit it and almost forget it for quite sometime.
How to Choose and Buy Dishwashers
Choosing house hold appliances isn't an easy task unless you are an expert or you are conscious of what your requirements are. It may be luring to decide in favor of an all automatic machine but it may prove a wrong decision if you run out of luck with it, just in case. Of course the first step is to decide whether you want a big one because you frequently make use of those large pans with long handles or the small one that fits under your kitchen cabinet. But there are more to choosing a dishwasher than meets the eye.
However, certain tips will not be out of place at this time.
Choose a dishwasher which has a stainless steel tub even if you have to pay a little extra for this. As time passes by, you will really appreciate this move for its perfect shape and surface. Stainless steel can sustain mechanical onslaughts and resists hard water corrosion in addition to the detergent effect.
Enamel coated steel tubs are, of course, built to last long and retain their original shapes but with the passage of time the enamel surface chips out and repairing it is a high cost affair as well as time consuming which, I am sure, no one will like to spend on their old dishwashers.
Noise is another concern you have to pay attention to while buying dishwashers. Dishwashers with muffler fitting help dampen noise through their operation. It can really get on your nerves if the noise level is any higher than 44 decibels. Check whether the machine can work under half load condition although it is advisable not to run it half load practically if all functions operate by default regardless of the load.
Check whether manufacturer's warrantee is only for replaceable spares or will it also include faulty workmanship too. Also, you can clarify with the dealer whether warrantee excludes labor costs for services during warrantee.
Make sure you are not paying higher than its due or than from the next shop. Recommendations work beautifully in your favor, and what better than a friend doing it for you?
