Question about Westinghouse 24 in. MDB421 RF Built-in Dishwasher

1 Answer

Dishwasher doesn't spray

* My dishwasher appears to fill up with water ok. * Once full it doesn't spray the water over the plates etc. * The timer appears to run as there is a humming sound. * After 10-15 mins it appears the water is pumped out and new water is pumped in. * Still the water is not being sprayed around. * Hence at the end when I open the door I have plates that have not been cleaned at all but it is quite hot inside the machine (looks like the water gets heated but it is not being pumped around to spray on the dirty items). Thanks in advance for any assistance

It sounds like your dishwasher is doing everything normal EXCEPT washing. The unit fills properly, the timer advances properly, the unit drains and goes through a rinse cycle, plus the water is heating. I would check your main wash pump for obstructions that may be clogging it, or if it is not running at all, you need to check the interconnecting wiring and/or something in the wash pump circuit that would prevent it from running. There should be a wiring diagram/tech sheet located behind the lower kick panel under the door. I hope this helps some. Good luck and let me know what you find.

Dishwasher leaves white film on plastic dishes and stainless steel . Salt is full and rinse aid is full.


If your dishes or plastic dishes appear with a white filmy 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.

Dishes don't seem to be coming clean in dishwasher. Plasticware seems cloudy and etched. Other plactic pieces look cloudy. Whites plates appear clean.



Hi


If you are noticing that the dishes are not clean, then there are a few things to check for. Check the soap powder if it’s kept in a dry environment. Also try replacing the powder with something like a gel or liquid. Next thing to check for is the water pressure and fill valve. Check if the water is filling in and the spray arms are throwing the water with enough pressure. Try and listen to the sound if you hear a proper spraying action sound. If it seems as a low water pressure then check the fill valve.

Now, check if dishwasher is draining the water or not. While the dishwasher is working check whether the dishwasher is draining and there is not much left out water after the cycle is complete. Try cleaning the spray arm with a soft brush.

The water temperature plays a major role in cleaning of dishes. The temp should be between 125 and 150 F for dishwasher to clean the dishes.


Please post back for any further assistance.

Running but not cleaning



Hi


Thanks for using FixYa. First of all please check the Water temperature by using a thermometer inside the dishwasher to measure the water temp. It should be as close to 125 degree F to 140 degree F as possible. Now try using the temperature boost feature if your dishwasher is equipped with this cycle feature and check if this will help your wash ability issues.

Now check the Powder soap by making sure that you store your soap in a dry environment and it is not stale and clumping together. Possibly try a different detergent like a liquid or gel. Also, make sure the dishes are loaded properly, or dishwasher is not overloaded.

To check the proper filling dishwasher will fill with water up to and around the heating element. If water is more below the heating element, you may have low water pressure or a problem with the fill valve. Try & listen if it sounds like it is spraying the water around with enough pressure.

For low water pressure, try to clean the screen at the entrance of the fill valve, sometimes the fill valve can fail and not allow the proper water into the dishwasher and may need to be replaced. And, check the spray arm and pump cover for splits or leaks. Also make sure that the water is draining and is not accumulated in the dishwasher, if it is in dishwasher then check for clogged drain hoses and drain pump.

Low water fills are a very common trouble maker with today's dishwasher.

Please do rate this solution and revert for further assistance.

Thanks

Dishwasher not completing cycles


Is the water being heated??? When the timer reaches the stage where it will not move forward any further, after 5 minutes or so, open the door & see if the water is heating up. The timer often waits for the water to reach the correct temperature. Temp is measured by the thermostat. If the element tests OK, then it could be the relay that switches the element. The relay is turned on & off by the timer. I would say that if the timer is OK & the element has the correct resistance, then it is is more likely to be the relay. Last resort would be the thermostat, but my money is on the relay.
