    Hi

    Thanks for your advice, the machine has been working fine for a year or so, detergent and rinse aid are both liquid and of good quality. I dont know what the variation is but I now have this 'feel'

    to the surface of the china dishes, no iron parts inside the wash area of the machine, does the rinse quantity setting have an impact?

    Thanks

    Thank you, the spray arm had some fine fibre in the jet, all is ok now.

Hi there,

Remove rust-creating items from the dish-load;
Use the recommended amount of granular (powder) detergent. Powders hold minerals suspended in the wash water better than gels.
Always use a high guilty detergent, some cheap stuff doesn't always dissolve good. Don't store your detergent under the sink(like most people do) -too humid,can destroy the active ingredients (in granular detergent).

NOTE: Installing an iron-removing unit in the home water supply may be the only way to completely eliminate this problem.

Post further comments for more information...

Good Luck!!

Thanks

    Well, problem seems in Spray arms -
    There's a spray arm at the bottom of your dishwasher--it may have a tall spray tube mounted to the center of it. There may also be a spray arm located directly beneath the upper rack of dishes and/or above the upper rack.

    If debris is blocking the holes in the spray arms where the water comes out, it could cause cleaning problems. Regularly inspect each of the spray arms and clean out the holes as necessary. 
    Thanks

I have a am-14 hobart washer. having problem with rinse temp indicator. it is fine for the wash then the temp gauge is jumping around, could it be the thermostat?


Your rinse temperature sensor that is a tiny probe in the water piping (top rear of machine) needs replaced. Hobart part # 00-294692. It costs about $84.

Hi, Our VFW post bought a used Hobart commercial dishwasher, model # wmp-es2 serial # 14054-302.We use the commercial soap,sanitizer, and rinse aid. The problem is,after washing the glasses they look...


Hi,

Check that the dishwasher is getting hot by feeling the temperature of the door - also at the end of the cycle when you open the door there should be lots of steam. If the machine is heating the water then increase the salt delivery a little - or even try a more expensive detergent to see if it makes any difference.

Temperature-



The single most important factor in getting good results is HOT WATER!!
The water must be at least 130o to work effectively. This is documented by the major manufacturers of detergents, such as Proctor & Gamble. Otherwise, greasy films will occur, along with soap residues left on glassware, etc. Use a candy thermometer in a glass under the running hot water tap on your sink to measure the incoming water temp. In general, it is best to always turn on the hot water at the kitchen sink for at least one minute to allow the actual hot water to flow. If not, the first couple of wash cycles will have cold water in the tub, and this wastes time, energy and soap. Using the delay cycle is never a good idea, since you will be assured of a cold fill the first few cycles.


Water Hardness-

Most areas have fairly hard water, which affects the cleaning properties of detergents. Hard water is water showing above 7 grains of hardness. Our Austin customers have, for example, 11-20 gr. hardness in many areas, mainly due to the limestone aquifer which supplies the vicinity. For them, I recommend filling both detergent cups full, plus using a rinse aid. If you don't know how hard your water actually is, we have a solution.



Water Hardness Test Kits- Know where your water stands to determine your strategy.


[IMAGE][SRC][/SRC][ALT][/ALT][WIDTH]100[/WIDTH][HEIGHT]100[/HEIGHT][STYLE][/STYLE][/IMAGE] Easy to Use!


Checks hardness in Grains. Takes the guesswork out of detergent measuring!



Great for monitoring your softener's efficiency!

- According to dishwasher industry statistics, approximately five million new dishwashers are sold each year. Many new dishwashers find homes in the 1.3 million new houses built annually. But that leaves 3.7 million other dishwashers-and most are replacing existing units that no longer perform because of lime scale, soap scum, iron and grease buildup. Based on an average cost of $400-500 for a new dishwasher, consumers are spending more than $5 million dollars each day on new dishwashers ($1.85 billion each year). Perhaps this would change if they had heard about the Dishwasher Magic product first :)



You can determine the cause of cloudy glassware by soaking a glass in vinegar for 5 minutes. If the cloudiness is removed it is a hard water deposit and more detergent is likely needed. If the cloudiness is not removed it is a permanent condition known as etching. In this situation, use less detergent and stop pre-washing. In actuality, dishwashing detergent needs a bit of soil to work on, otherwise it will tend to foam up.

Maintenance Techniques-

Every two months, run the unit with a quart of white vinegar added to the tank (no dishes or detergent for this!). This removes any deposits left behind in the tub, and actually helps keep the drain clear! Do this mainly on units with plastic tubs, since they are porous, and will absorb not only grease, but residue from the detergent.

Use a rinse-aid, such as Jet-Dry, in your dishwasher, unless you have a water softener. In this case, do NOT use a rinse aid, and reduce your powder detergent to one teaspoonful per grain of water hardness. We recommend the solid form of the Jet-Dry, not the liquid. For one thing, the liquid is harder to deal with than checking a hanging basket visually. Also, the liquid dispenser only injects a couple of drops of liquid into the unit at the end of the wash cycle. This does not take into account varying degrees of water hardness in different areas. The solid version is always working right thru the wash and rinse cycles. Hang it in the left front corner of the upper rack for the best distribution.





Detergents- Gel or Powder?


Gel detergents are not the best solution for your dishwashing . They create more problems than they resolve. A few examples include:


Gels contain chlorine bleach (dissolves rubber seals)

Gels tend to cloud glassware, leaving a whitish film.

Gels never really rinse off of interior tub or from sump area.

Gels clog the detergent dispenser, making it release late or not at all. This causes door streaking by the chemicals.

Gels don't work well in hard water, they leave spots


Always use powdered detergent or tablets, and make sure that your water temperature is at least 125-130o to the dishwasher! It makes a world of difference in the final results.

The problem is usually the water not being hot enough and the detergent. need to try buying small containers of different detergents and see with works best with your water and machine. hard water and the wrong detergent causes this problem.Perhaps you changed detergent lately or they changed the formula of your detergent. Or your machine is not heating the water properly any more. Like a failing heating element.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

We have a hoshizaki ice machine 901mwh the ice cubs seems to be getting stuck in the evaporator area and pileing up on it self and freezing bake up


The main problem with Hoshizaki machines is if you are in a hard water area, if so do you have a good quality water filter, it may need changing. A quick way to check for calcium ot lime deposits in the machine is
1. Turn it off, run you clean hand around the area near the evaporator, are there any rough or flaky deposits there, if so you may need a chemical descale, contact a reputable fridge guy to do this for you.
2. The swinging arm motor may be faulty or possibly the ice sensor which controls the harvest cycle. If this is faulty sometimes the tray goes back up before the ice has slid off.
3. If the machine is situated in a cellar or other cool (less than 10 deg C / 50 deg f) this can sometimes affect the harvest cycle again to set this you need a tradesman.
4. Does the water flow properly over the lower part of the mould plate during a harvest cycle, the pipe can become blocked or dislodged.

Hope this is helpful

All glasses and plates have a cloudy film remaining after wash


Hi
White film deposits are observed if water is hard or when you are using more detergent than needed, try filling detergent cup half way. Try using white vinegar after the wash cycle is complete, run a complete cycle. Also turn down the heat on the hot water fed to the dishwasher. Try using water softener for better results.
You can also add vinegar in the final rinse cycle. Make sure that your soap dispenser drawer is opening and closing fine.
Hope this helps... Please post back if more information is required.

My dishwasher says that it needs salt what sort of salt and how much?


HOW MUCH SALT DO I NEED TO ADD?


shim.gif
shim.gifYour machine may have a float indicator or a warning light to tell you when salt needs adding to the water softener. Often float indicators are difficult to see, and there is no accurate guide as to how much salt you need to add. Quite simply, just add granular salt to the reservoir until it won't take any more!


The softener will use the salt to replenish itself each time you wash. As an approximate guide, you should do a full top up about once a month. If your machine doesn't have a warning light, a good way to remember to check and / or top up is to do it on a regular day of the month (e.g. the first Saturday or the 15th)

CAN I USE ORDINARY TABLE SALT?

No. Table, cooking, rock and sea salts may contain additives that can actually increase water hardness. Also, the fine consistency of some of these salts mean they are likely to clog when wet. Always use granular dishwasher salt because it is very pure and is the right consistency for use in your machine.

Granular salt is the ONLY type of salt that should be used to regenerate the softener. Be aware that some varieties of 'dishwasher salt' use Dead Sea salt. This variety may contain minute insoluble organic matter that may adversely affect the resin within your softener over time. If you are in doubt about the origins of the salt, ask the retailer or manufacturer.

Dishes not clean


hi friend,HOW TO GET THE BEST FROM YOUR DISHWASHER
Always follow the manufacturer's instructions and read the directions carefully on detergent, rinse aid and salt packaging.
Cleaning your machine about once a month will remove any grease and lime scale deposits which can build up on the inside of the machine. Special dishwasher cleaning detergents are available which are used when the machine is empty. These cleaners will often leave a fresh smell in the dishwasher too. If you want to have that fresh smell all the time, use a dishwasher freshener. These are usually supplied as hanging tags, which should be carefully positioned away from any moving arms. A freshener is essential if you load during the day and then run the machine at night.

A freshener is essential if you load during the day and then run the machine at night.
LOADING

These items can be washed in a dishwasher, with the following guidelines:
Glassware - Any ordinary glassware and ovenware such as Pyrex. Do not wash lead crystal glasses unless they carry a "dishwasher safe" label.
Tableware - Most everyday crockery is safe. Bone china usually has under-glaze decoration and should be safe. Avoid antique or hand-painted and over-glaze decorated items. If in doubt, check with the manufacturer.
Cutlery - Stainless steel and silver cutlery are normally suitable for machine washing, but it pays to rinse off any acidic food before loading to prevent any corrosion and, if possible remove the cutlery immediately after the cycle, to avoid prolonged exposure in a humid atmosphere. Do not mix steel and silver cutlery in the same basket and wash bone or wooden-handled items by hand.
Plastics - Check whether they are dishwasher safe and do not place in the lower rack, where the heating element may affect the plastic during drying.
Pans - Stainless steel is ideal for dishwashers. aluminium can be washed in the machine, but may discolour during the rinsing. If in doubt, remove aluminium pans before the rinse cycle.
Always wash cast iron and wooden handled items by hand

WHY DOES MY MACHINE HAVE A WATER SOFTENER?
If the water is soft (i.e. does not contain calcium particles), the detergent will work more effectively and there will be less streaking on dishes. Hard water can also block the washer jets with lime scale and cause deposits on heating elements, which will reduce the cleaning efficiency, increase electricity costs and shorten the life of the machine. All dishwasher manufacturers (Bosch, Miele, Siemens) and detergent suppliers want you to get the best results from the machine - and soft water is one of the most important factors in achieving this. The way to ensure water remains soft is to regularly top up the reservoir with granular salt.
Three in one salt tablets do not activate the water softener.
HOW MUCH SALT DO I NEED TO ADD?
Your machine may have a float indicator or a warning light to tell you when salt needs adding to the water softener. Often float indicators are difficult to see, and there is no accurate guide as to how much salt you need to add. Quite simply, just add granular salt to the reservoir until it won't take any more!

This variety may contain minute insoluble organic matter that may adversely affect the resin within your softener over time. If you are in doubt about the origins of the salt, ask the retailer or manufacturer.
WHAT DETERGENT SHOULD I USE?
All modern dishwasher detergents are formulated to work specifically in dishwashers. On no occasion should ordinary washing up liquid be used, as it will cause excess foam, which can result in a leak. If it is accidentally used, sprinkle ordinary salt into the chamber to disperse the resulting suds. Then rinse away the excess salt before using.
There are 3 main types of dishwasher detergent - Powder, liquid or gel and tablets. Which one you choose will be down to personal preference, but most people find tablets very convenient, although using powder is usually more economical and liquids are less abrasive on more delicate items.
WHAT IS RINSE AID?
Rinse Aid is added to a special compartment in the machine and a very small amount is released during the final hot rinse cycle, to reduce the formation of water droplets on crockery etc and so ensures that the water dries away properly and evenly to avoid leaving smears.
Dual action detergent usually contains rinse aid, which is released at a different rate to the cleaning agent and so helps reduce smearing etc without the need to add separate rinse aid. Some 3-in-1 tablets contain an ingredient, which has a 'salt action', which also helps to improve cleaning, but NOTE this is not a substitute for adding salt to the water softener.

The salt action takes place in the cleaning chamber of the machine, but does not actually replenish the water softener. Research has shown that whilst 3-in-1 detergents do clean dishes effectively, their performance is improved by adding salt to the water softener reservoir.
As the performance of machines can vary, as can local water conditions, it is always best to follow your manufacturer’s advice. Some manufacturers advise that if you have unsatisfactory cleaning performance eg white powder residue, poor drying or dirty dishes, then you should return to using three separate products ie detergent, rinse aid and granular salt. Be aware that if you have not been filling the salt reservoir and relying on the salt in 3-in-1 tablets, then it may take a few cycles to re-generate the softener.

Water left in fabrish softener dispenser after wash cycle


My Frigidaire front loader was doing the same thing and also not taking the bleach. I could hear that the water pressure was not real strong when I turned the machine on. I removed the two small screens on the back of the machine where the water supply hoses attached, found they were partially clogged and cleaned them well. The bleach and softener dispensers are now working like new.

Where can I find a mnaual that can tell me how to de-lime a Hobart CRS66A Dishwasher?


I doubt that the user manual covers de-liming the Hobart Dishwasher.   If I owned this (fine, expensive) dishwasher, this is what I would do.
1.) Discard any generic, ultra-cheap detergent.  Stop using gels or tablets and only use powders.  Buy a box of brand name powder (like Electrosol or Cascade)  You will be amazed how much difference that will make because the newest generics have mineral bulk added that build up faster then hard water does on both the stainless steel enclosure plus the silverware and even plates.  White patches.  I LOVE generic products and saving money, but low end dishwasher powder is one place I no longer choose a generic product.
2.) Add two cups of white vinegar to the empty dishwasher and leave it there until the morning.  Run a quick cycle with no detergent added.  The vinegar will be pumped out immediately after you begin this quick cycle.
3.) As soon as the dishwasher fills with water during that quick cycle and begins a wash cycle, add two cups of white vinegar and close the door and allow to run the full wash cycle.
4.) When the dishwasher finishes the drain cycle and begins to fill again, open the dishwasher and check the enclosure for remaining "lime" deposits.  If they remain, keep adding 2 cups white vinegar each time the dishwasher refills and begins to wash/rinse again.
You should be delighted with the results. Long term, you should consider adding a whole house water softener and then reduce the amount of dishwasher (and laundry) detergent by one half.  Amazing increase in quality of life by adding a water softener.  You will be delighted.
Please post back with you results, OK?  Good Luck!

When should u add softener?


Dear seymour,

please rate this solution if it meets ur need else choose fixya.

Fabric softener is one of those things we don’t think much about, but use frequently. How does it work? How is it used? Fabric softener is essentially a chemical cocktail that helps soften the fibers in textiles. It makes them feel less harsh and has anti-soiling and anti-staining properties. With such names as Diethylenetriamine, Aminoethylethanolamine and Triethylenetetramine, these chemicals sound like something out of a science-fiction movie, but they are mostly byproducts of animal fats. Fabric softeners come in two types: liquids and dryer sheets. The liquid softeners are added to the rinse water for each load of clothes. Dryer sheets are paper or sponge-like pieces that are coated with the dry softener and are added to the dryer for every load. Some liquid softeners tout that they will leave clothes brighter and prevent discoloration from chlorine. These claims must, of course, be evaluated by each person.

Fabric softeners are used in any form to help make clothing feel softer and to prevent static cling. Anyone who has unloaded a batch of towels from the dryer in winter knows exactly what static cling is. Dryer sheets lubricate the textile fibers to reduce static electricity generated by the drying process. Liquid softeners serve much the same purpose.
There is a great amount of information about fabric softeners on the Internet, and while browsing, a person will undoubtedly come up on Web sites saying the chemicals in fabric softeners are dangerous and can cause a whole host of illnesses and allergies. There is no doubt that some people are allergic to the chemicals and/or dyes in fabric softener. They can cause rashes or upper respiratory distress. Some manufacturers have started producing dye and fragrance-free liquid fabric softeners in response to this problem. Some small companies also produce a vegetable-based, dye and fragrance-free softener that is biodegradable and less likely to cause allergic reactions. There are also some ways of softening the laundry without using any kind of commercial fabric softener. Vinegar and baking soda soften the fibers naturally. A person can add one-fourth cup baking soda to the load at the beginning of the wash cycle, and then a half-cup of white vinegar during the rinse cycle. Another home recipe suggests diluting 1 cup of glycerin in a gallon of water and using one-half cup of the mixture per load of laundry. Still another method uses three parts water to one part commercial hair conditioner. Fabric softener should only be used with standard fabrics. Fine washables such as linen or silk should not have any kind of fabric softeners used on them, if they are machine washable. The chemicals can destroy the look and feel of a fabric like linen, and dull colors in silk. However, most standard cotton and polyester blends are safe with the use of fabric softener. Dryer sheets are a blessing for socks and towels, since these items seem to be most susceptible to static cling. Liquid fabric softener can also usually be diluted to one-fourth strength in order make it last. There is usually no discernible loss of softness or increase in static cling when the softener is diluted. Each person needs to decide whether using a commercial fabric softener is appropriate. Those with allergies or very sensitive skin may want to consider a home recipe, since they are made of ingredients that are readily available. People also need to remember to keep the fabric softener from their fine or delicate washables, especially linen and silk.
