My Bosch SHU436UC/17 goes thru its cycle OK, but dishes aren't very clean. During the wash, the water isn't very warm, but at the end of the cycle, the dishes are very hot. Any ideas?

Tablet not desolving after quick wash cycle

Find out whether your quick cycle is a wash cycle or a rinse only. If it is a wash it's obviously too short, and the tablet is not dissolving. You do not want undissolved tablets because they will contaminate your rinse water and u end up with soap on the dishes. You can switch to powder if a tablet isn't going to dissolve quick enough on your quick cycle.

Just got a new Bosch dishwasher (forget which model). After the dishwashing cycle has ended (even long after), the dishwasher and dishes are still wet. Was this an installation problem? Thanks

Hi -
I can't see how any installation problem would cause this - if the dishes are still wet at the end of the cycle, you'll probably find the water isn't heating during the wash cycle. The dishwasher uses steam to heat the washing compartment and dry the dishes. It would appear that the dishwasher isn't heating water internally.
Even if the washer was accidentally connected to the cold water supply ** (see note), this shouldn't happen as regardless of the water supply temperature, the washer should still heat the water to the correct temperature internally.
** UK dishwashers should be connected to the cold water supply. For US installations, dishwashers are commonly connected to the hot water supply. For other locations, please consult your installation instructions.
I suggest you start a regular wash cycle and leave it to run for 10-15 minutes. Then open the door and test the temperature of the water in the base of the washer by hand. The water should be hot and there should be steam present in the washer when you open the door.
If the water is cold or only warm, the water isn't being heated internally or isn't heating to the correct temperature, in which case you should contact the retailer or Bosch Service immediately for a replacement. Do not accept an offer of repair on a brand new washer!
Additionally, do not attempt to repair the dishwasher yourself when under warrantly as this will invalidate the warranty.
Hope this helps. If you need further assistance, please let me know your location and the model number of the washer. This should be laser-etched into the top of the door if you can't find it on any of your paperwork.
Regards, BElectric

We get a white film on dishes and silverware after running then dishwasher. It 's getting worse gradually over time. What is the cause and how do we correct it.

If your dishes or glassware appear with a white film or a white powdery residue or spotted following a complete wash cycle, adjusting the amount or type of detergent you?re using and adjusting your hot water heater?s water temperature may solve the problem. But before you do either of these, put a rinse additive (such as Jet-Dry) in the rinse dispenser to improve the sheeting action of the water.

Next, you?ll have to determine whether the film is removable or permanently etched. To do this, soak a glass in undiluted white vinegar for about 15 minutes. Or, wash the glass with warm water and concentrated dishwasher detergent or a high-phosphate detergent (such as Glass Magic).

If the film comes off, it is probably caused by hard water minerals, improper amounts of detergent, or unsuitable water temperature.

Permanent etching is often caused by a combination of soft water and excessive heat or detergent. If glassware is permanently etched, there isn?t anything you can do to make it clear again. But you can avoid future etching by taking these steps:

1) Be sure hot water entering the dishwasher is no hotter than 140 degrees F. Don?t use extra-hot settings such as ?Power Scrub,? and use the ?Energy Saver? dry cycle.

2) Adjust the detergent amount.

3) Don?t pre-rinse your dishes before loading them in the dishwasher. Food particles on the dishes actually help the detergent and drying agents clean better.

A common cause of poor washing results is improper loading?dishes that block or impede the spray arm(s) or prevent the soap dispenser from opening. On the other hand, if your dishwasher has chronic problems with good washing, the problem may not be your dishwasher. A good first step is vary the amount of dishwasher detergent you're using and try switching brands.

Other possibilities: Your home?s water pressure may be too low, your water may be too hard, or the water temperature may not be hot enough.

In order for your dishwasher to fill to the appropriate level, water pressure should be from 20?120 pounds per square inch. If you suspect that your water pressure may be low, turn off all faucets or other users of water (such as washing machines and sprinklers) and then put a half-gallon jug under the kitchen faucet. Turn on the hot water full-blast. If the jug doesn?t fill within 14 seconds, your water pressure may be too low for proper dishwasher operation. Call your city water utility to discuss your options, or avoid drawing water elsewhere in the house or yard during dishwasher cycles.

The right amount of detergent to use depends on how large your load of dishes is and how hard your water is. Hardness is measured in grains of minerals?the more grains per gallon you have, the more detergent you?ll need. If your water has 12 grains or more of hardness, fill both dishwasher soap cups completely with detergent. If that doesn?t work, consider installing a water softener. (For more information, see the article Water Softener Systems.

To check water temperature, hold a meat thermometer under the hot water faucet for two minutes; if it doesn?t register a minimum of 140 degrees F., turn up the temperature dial on your hot water heater. (However, if you have a newer dishwasher that heats the water internally, it isn?t necessary to turn up your hot water heater.)

If your dishwasher has worked fine in the past but suddenly your dishes aren?t clean after the dishwasher completes all cycles, listen to the spray arm(s) spinning inside during the wash cycle. If spinning poorly, wait for the machine to cool down, remove the spray arm(s) by unscrewing the hubcap(s), lifting the arm(s) off, and then cleaning out the spray holes in the spray arm(s) with a stiff piece of wire.

Washing machine cycle far too long

Hi Fiona.I believe the cold valve is probably faulty & is not flowing fast Its probably dribbling water in?taking forever to fill.the machine should be giving up & beeping at you if thats the case.If you have a faulty cold valve then switching to warm won't help as the hot valve will close itself off to compensate for the lack of cold water..afterall you have told the machine to fill with warm,,if it cant make warm water because of a faulty cold valve then the hot will decrease to a point where its not letting any water thru..try a hot only wash..if it goes thru wash cycle ok then good chance its cold valve problem.wow i hope that helped.

Kenmore washer series 80, Clothes still soapy

If you are getting no water spray during the rinse cycle that would cause the soapy clothes issue.

Are you getting cold water during the wash/rinse cycles? If you have the machine set to warm/warm you may only be getting hot water while the final spin is calling for cold.

If you have cold water available then the timer is not calling for the water spray. The problem is either in the mixing valve or the timer.

Water left after finishing wash

I have a Bosch Dishwasher and the E-Nr is SGS4362EU/03. The machine is approximately 4 years old, in good condition and has been working very well. Suddenly, there is water remaining after it completes a 50 degrees C wash cycle. This is also evident with the pre wash cycle and the 65 degrees wash cycle.

I have checked and cleaned the filters. I have loosened the internal pump white cover (Torx T 20 screw) and checked for any physical blockage - none. I have also checked for any drainage hose kinks - none.

I have tried a series of empty washes and the machine drains the water during the wash cycles. The dishes are also have a dull colour and show show signs of not being properly rinsed during the wash cycle.

Please assist.

Brian
