Question about Dishwashers

1 Answer

My Bosch dishwasher has several problems: 1) Water doesn't completely drain out and dishwasher kind-of smells when I open it -- I do keep the filter very clean. 2) The dishwasher takes HOURS to go through one load, no matter what the time says on the display and no matter what type of cycle you choose -- quick, delicate or regular. 3) The red display often displays something that looks like "2h" at the beginning of the cycle. 4) The place where you put the detergent doesn't shut. Please let me know what is going on with it. Many thanks, Kathryn Schwartz

Hi Kathryn .

I think you have a defective pressure switch. The pressure switch is located near to the drain pump, and the device is used to determine when water had been drained completely.

Also check the floater switch located inside the tub.

Regarding your problems:
1) Water doesn't completely drain out and dishwasher kind-of smells when I open it -- I do keep the filter very clean.

A: that is consequence of poor draining, water remaining inside the tub will smell.

2) The dishwasher takes HOURS to go through one load, no matter what the time says on the display and no matter what type of cycle you choose -- quick, delicate or regular.

When pressure switch is broken, drain may take a long time. Check also that you have hot water, or you may have an additional problem with heating system or inlet valve (depending on the model)


3) The red display often displays something that looks like "2h" at the beginning of the cycle.

A: '2H' is a default that is indicating the previous wash cycle ran longer than it was programmed for.

4) The place where you put the detergent doesn't shut.

A: this has nothing to do with drain, it is a bad detergent drawer solenoid, or a problem with contact to control panel.

Conclusions: You need to have the pressure switch tested, the pump hose checked for blockage, and the door drawer solenoid tested.

Since on this appliance there may be more than one fault , I think that the best thing to do would be calling the number listed on the owner manual to arrange a repair.

If you want I can give you more indications on how to test pressure switch, solenoid etc. The job must still be done by a technician on site.

If my solution had been helpful, then please do not forget to leave feedback.

Thanks.

G.

Our dishwasher won't drain completely. I ran it through a regular cycle but it was left with water in the bottom.


Have you tried canceling the cycle? To cancel, turn the on/off switch to on, then press and hold for three seconds the two buttons labeled "Cancel Drain". Keep the door closed for the next minute so that the dishwasher can complete the cycle. During this time the pump will remove any water from the washer. Also you will notice that Bosch dishwashers always leave a little water in the system to keep the seals from drying out and going bad.
Hope this helps

Check the drain line underneath the sink.
It should be suspended just below the counter top.
If it is too low,water from the sink will back fill into the dishwasher.
If the drain is OK,then the dishwasher water valve is defective.

Dishwasher: BOSCH SHE43 - pump keeps draining


Your dishwasher is stuck in flood mode. Bosch dishwashers are built with flood switches located in the bottom base pan of the dishwasher. The flood switch is connected to a rod that activates a small interlock switch. When water enters the base pan on a Bosch dishwasher, a Styrofoam puck lifts the rod, activating the flood switch.

When the flood switch is activated, the dishwasher will go into a no-fill, only-drain mode. The drain motor may also run with the door open to the unit. This is definitely a sign there is water in the base pan. This can be caused by the drain being clogged. There are two ways to fix:

1. You can uninstall the dishwasher and tip it forward to about a 45 degree angle to drain the water out of the base pan. (This is probably why Ian Bint's solution fixed the problem.) Be sure to put a towel under the dishwasher first so that the water is soaked up in the towel instead of going all over the floor. Once you've drained all the water out of the base pan, reinstall the dishwasher and begin a cycle. If it fills and runs, you are good to go.

2. You can also unplug the unit, then remove the kick panel at the bottom in the front. (It's attached with two screws.) Then get some old washcloths or small towels and reach into the base pan below the dishwasher to soak up the water. The pan is directly behind the plastic base panel rim. Once the pan is empty and dry, your dishwasher will no longer be in "flood mode" and will run properly.

If the base pan keeps refilling with water and the no-fill problem returns, there is definitely another issue, such as a clogged drain. At this point, you need to decide whether to invest in an expert evaluation by a certified Bosch repairman and make the necessary repairs, or buy a new dishwasher.

Dishwasher smells like fish


There are several possible causes.

First, make sure the machine is properly installed with the drain hose up in a loop or an air gap before going down to the drain. This is to ensure no dirty water or smells from the sour or garbage disposer backs up into the machine.

Sometimes nasty stuff gets trapped inside internal parts of the machine and inside the sprayer arms. It is normally easy to remove the sprayer arms for cleaning, on reasonably modern Bosch machines they can also be opened up for easy access.

There are also special dishwasher cleaning agents that you can use to perform periodic cleaning cycles. Some believe it is important to use rinse agents to minimize the problem, maybe it is worth trying if you don't use it.

If there is warranty left on the machine I would advise you to complain, there is a slight possibility there is something wrong in the machine for instance bad choice of insulation lining that have been known to emit foul smells.

Good luck with tracking down the cause of this!

Try running citric acid (3 tablespoons) through.
You can get it from a drug store.
Or, run 1/2 cup vinegar through.
Do this in both the dish washer and the disposal.
After doing this try running some water into the disposal and then see if the next time you run the dishwasher if it still smells.
You could be having a problem with water not staying in the drain trap under your sink that is why if you run water and fill the trap, then you will find out if it was the dry trap that caused the smell from sewer gases backing up into the house trough the garbage disposal.
