    Note: there are no screws either side of the dishwasher, do you need to remove the base plate to access the screws to open the bottom?

Since water doesn't drain out ,it could be a clogged in the drain line. Often the problem is at the point where the drain line attaches to the garbage disposer or household drain line. You should remove this line and clear it form any debris in the hose or the hose connection. Be sure to reattach the hose before starting the dishwasher again. Good luck!

SOURCE: Diplomat intergrated dishwasher error code FA

FA is a problem with the tubidity sensor. By holding down the power button, it stops, but just repeats everytime you try a new wash cycle. So keep doing it and you can atleast use it. If you want to go one step further and find a permanent solution try feeling around in the sump (where the filter slots in) being careful for any broken glass. Other than that it will probably be a strip-down job to examine the internal hoses and the pump; not a DIY job to be honest.

I just read this for the same problem: push sanitize, then heat and dry, sanitize, heat and dry, sanitize, heat and dry, cancel, then open and close the door. It worked. The dishwasher is running correctly even as I type this.

If you are still trying to sort out this issue try the following.

From what you say then it is most likely the aqua sensor on the side of the dishwasher. The gurgling sounds that you hear are likely the drain pump running and the un-drainable water sloshing in the sump.

Verify that there is actually water going to the dishwasher( Basic step but often overlooked)

Next the inlet valve will have to be checked. This is the part where the water line from the house connects to the dishwasher, under the toe/kick panel. Remove power from the dishwasher. Disconnect the dishwasher electrical connections (2 wires) to the inlet valve and connect it (carefully to 110 V power) using a jumper wire. With 110V power the valve should open and water will flow into the dishwasher, if not then the fault is in the inlet valve.

If this checks fine then the fault is likely in the aqua sensor...

On the outer left side (viewed from front) there is a panel, Behind this panel there is a small clear(of light blue) plastic mechanism with hoses and wires attached( There is usually a yellow disk at the top about 6cm in diameter) this is a float and sensor assembly there is tells the control the water level and works as an emergency drain if there is an issue. There will be a red stick protruding downward to the base and a Styrofoam float on which the stick rests. This is a pan overflow sensor if the stick is too high the unit will go into drain and cut off the fill valve power. The yellow disk is a diaphragm which senses water height. This unit can become stuck with wear and hard water.

Hi I have an Bosch SGs43c02gb/35 and it does not drain all of the water out when it has finished the cycle, I have cleaned the filters out which were relatively clean and run it with a dish washer cleaner...

Hello

It is quite common for a dishwasher to not drain because either the drain hose or the air gap (if the unit has one) is clogged up. Drain hose clogs commonly occur where the hose is attached to the main household drain line, or where the hose connects with the garbage disposer. Try removing the drain hose to unclog any debris. Don't forget to reattach the hose before you start your dishwasher again.

The pump assembly is comprised of a pump, wash impeller, and drain impeller. The pump ejects the water from the unit, the wash impeller pushes water through the spray arm, and the drain impeller directs the water towards the drain port. Examine your dishwasher's pump assembly. Clean out any debris that may be blocking it. Replace the pump assembly if any of its parts appear to be worn or defective.

It isn't very common, but sometimes a dishwasher's pump assembly is driven by a belt. If that belt becomes worn and defective, then it cannot properly run the pump that drains your dishwasher's tub. If your dishwasher uses a drive belt, examine it now. If it shows signs of wear, replace it.

A defective timer could interfere with a dishwasher's ability to drain properly. Test your dishwasher's timer mechanism. If it is faulty, replace it. Keep in mind that you can replace either the entire timer assembly or just the timer's motor.

The motor plays a key role in a dishwasher's ability to drain water. If your dishwasher's motor is not functioning properly, it will negatively affect the draining capability of your machine. Test your dishwasher's motor for continuity. If it fails the test, replace the motor.

In some models, a valve has to open in order for the water to drain out of the dishwasher. This valve is controlled by a solenoid, but it is the timer that decides when the valve should open. If your timer is working fine, check the drain valve and its solenoid. If need be, replace them.

I am having issues with my dishwasher where it appears to be working but does not clean. Hot water does enter the unit and drains properly but is not cleaning. Muck is still on the door, the arms are wet....

No you need not wash the dishes but just cleaning of the debris and then putting it in the dishwasher for proper cleaning will help you to prevent the drain from getting blocked.

First perform a vinegar cycle wash in the dishwasher. Pour a cup of vinegar into the bottom of the dishwasher. Keep the temperature at the highest setting possible and perform a wash cycle.Then start using a dishwasher most probably that would solve the problem. If this does not solve the problem then there must be some parts worn out or faulty creating the problem.

There are many probable causes of failure .

To clean the dishes the water temperature is essential.It the water is not hot then the dishes will not be cleaned properly.So check the water temperature.

Also check the filter in your dishwasher.Clean the filter if there is accumulation of debris in the filter.

Dishwasher- dishes not clean

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

Glasses in top rack not getting clean anymore.

-Have you changed the dishwasher soap recently? What are you using? Is the powder remaining behind in the soap dispenser?
-Have you removed the filter in the sump area, cleaned it and removed any debris under the filter. (watch out for broken glass that is almost always found in 5 year old dishwashers.)

-You are running water at the sink until it gets hot, but you may still have problems if the heating element has failed. Recommend you check that element. If you can get to the element, check resistence of the heater to see if is has any at all.
If heating element checks out good, the next common problem is a failing wash pump motor.

FOOD PARTICLES ON DISHES

Hi

If your dishwasher is cleaning poorly, check these:
Water-inlet valve Most cleaning problems are caused by the dishwasher not getting enough wash water, so the water-inlet valve is often to blame. This valve is usually at the bottom left or right of the dishwasher, behind the lower access panel. It's the device with the main water line from the house, a rubber tube to the dishwasher, and two wires attached to it.

When a water-inlet valve is defective, you may hear the sound that's usually referred to as "water hammer." If the water-inlet valve is defective, you need to completely replace it.

Internal filters Every dishwasher has some type of filter to keep large food particles and foreign objects away from the pump assembly:

  • Most modern dishwashers have self-cleaning filters that don't need any routine cleaning.

  • Some have filters in the bottom of the dishwasher that you need to periodically clean. You don't need any tools to remove the filter, and cleaning it is easy. Consult your owner's manual to determine which type you have and its maintenance requirements.

If your filter is clogged, it may be causing the cleaning problem.

Drain valve Some dishwashers have a valve (or gate) that should open only during draining. If debris lodges in the valve, it can't close properly, so water drains out during the wash cycle. Most dishwashers drain into the garbage disposer. If yours does that, listen for water flowing into the disposer during the wash cycle. If you can hear it then, the drain valve may be clogged.

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.

Water temperature To get the best cleaning results, the water entering your dishwasher needs to be hot enough. Try running the hot water in your kitchen sink for about 30 seconds before starting the dishwasher, to pre-heat it. Also, if your dishwasher lets you select a higher wash or rinse temperature, try that to see if it helps.

To check the temperature of the hot water that comes from your kitchen faucet use a waterproof thermometer. If the water isn't 120 degrees Fahrenheit, your dishwasher may have trouble getting your dishes clean. You could increase the temperature of the hot water to the whole house--and therefore the dishwasher--by adjusting the hot water heater thermostat.

Warning! To lessen the risk of scalding, don't set the hot water heater temperature higher than 120 degrees Fahrenheit.

Detergent cup Dishwashers don't perform their best if detergent is introduced only at the beginning of a cycle, so add detergent to both parts of the cup.

If the detergent cup isn't opening, see the "The detergent cup doesn't open" section, below.

Note: Dishwashers are usually wired directly to the home’s electrical system. To disconnect the power, switch off the circuit breaker or remove the fuse for the electrical circuit the dishwasher is attached to. Try to turn the unit on after disconnecting the power to be sure you were successful.

CAUTION: If you’re not sure you’ve shut off the power properly, DO NOT CONTINUE. Call a qualified appliance repair technician to complete the repair.

Soap foam left after dishes are washes. can't dry properly. and always has soapy water left in it and on the washed plates.

Try adding some liquid fabric softener to your dishwasher. This will reduce the foaming. Also make sure there is rinse agent in the proper dispenser, this will reduce the soap sticking to the dishes. Finally, reduce the amount of dishwasher powder or liquid you put in for each wash. If water remains in the bottom of the dishwasher, check if there is a filter or drain hose clogged. Is the dishwasher drain hose connected an undersink garbage disposer? If yes, make sure it is run periodically so it does not clog up.
