Water fills up, nothing happens at all until the end of the cycle and the water drains. Fixable?

There is a temp sensor that tells how hot the water is and it is either bad, or the heating element wont warm the water so it drains.

A-- If you hear the water filling for 3 minutes before the lights flash, 2 things could be happening:

a.1) water never reached the proper fill/run level so the computer prevents the heater from starting and alerts the user. There should be a code list in the troubleshooting section of the user manual describing the blinking lights and what they mean.

Solution- verify by sound if water flows at the same rate as the sink tap, if not then shut off the water and check the inside the connection hose for debris against the screen inside the hose end or insid ethe machine end where there is a intake valve. The debris keeps sediment out so it works but there's no auto cleaner for the screen.

a.2) Otherwise the heater itself is faulty meaning it does not conduct an electrical path or maybe overheating (could be dry) and the computer senses the wrong temperature either too high or too low.

Solution- A service call to determine the reason why; heater continuity, water valve, heater relay, hi-temp fuse, etc.

B-- Now, if you do NOT hear water filling for those first 3 minutes, 3 things could be happening;

b.1) House water supply is turned off.
b.2) hose is clogged (see solution a.1 above)
b.3) Drain pump inside dishwasher was clogged during the last run and old water didn't drain out (maybe some water is evident in the tub bottom).
Solution- Most dishwashers start each wash cycle with 30 second drain pump running to make sure the tub is completely emptied so the next fill cycle can't overfill. This ensures that if the user finds a 3 liter pot that flipped over during the last wash and if they dump that full pot of water into the unit to make it lighter, that the water will get drained before the new water enters the tub.
If the drain pump is clogged reset the power and restart the wash cycle. Note how much water is in the tub and see if it goes down any during those 30 seconds by opening the door afterwards. Find the clog either a bone or plastic bag or some small pice of a childs toy is stuck in the drain pump or the other end is clogged maybe by grease or bones if you have a sink disposal unit. The things they grind up drop into the drain 1" inch above the hole for the dishwasher drain tube.

NOTE: There is also an overfill [float] switch if the water inlet valve gets stuck open and the water keeps filling, the drain pump is switched on until someone comes and shuts off the water supply. When the tub drains the float drops and the drainpump stops. This will also make lights blink so check the user manual for codes or call the factory service reps [1-877-337-3639].

Either way, there should be instructions to reset the machine for restart. If it doesn't reset you need someone to fix the control that tripped the unit, maybe a safety fuse or a broken piece of the puzzle.

If your dishwasher is brand new, then call Bosch service as they can repair it under warranty.

Hello Kimberley,
It appears that a part of your question is cut off so i may be off base here but what i am reading is that your washer will go through the wash cycle and drain the wash water then just quit?? is that what is happeningIf yes that is whats going on i think what is happening is that after the wash cycle it fills with only COLD WATER for the rinse cycle and its not filling with the rinse water and just sits their until the rinse cycle water is filled and if its not getting cold water into the washer its not going to do anything If it is filling with cold water my apologies my bad for misinterpreting what the question reads and i ask ya to re-ask it.

You need a timer the motor contacts are probably burnt.

it does not aggitate? Thats the cycle that allows the water to wash the clothes. It may be broken, I have had that happen a couple times. I would take the aggitator off and see if the teeth in the groves are worn out, It happen's when used alot. Commen problem and easy to replace.

For the machine to keep filling it would indicate that there is a siphoning problem. Check the outlet hose is not running along the ground, it has to rise up then loop back down or the water will just run straight down the drain. If the problem only happens after the first pump out it would indicate the end of the outlet hose is lower than the drum or there is no air break around the outlet hose. (The stand pipe should be larger in diameter than the hose from the machine).

Hello , here is the fix-your drain hose is placed to low in the drain line in the wall, it can not be placed in water or it will siphon the water out of your washer into the drain pipe and it wont stop until it hits air. try pulling your drain hose up and out of the drain and get a zip tie or cable and tie it to one of the water valves by the drain pipe placing the end of the drain hose about 5-6 inches inside the drain pipe. Let me know if you have any other questions and good luck it will work.

remove bottom cover look for tech sheet usually on right side of cabinet at bottom fh is usually a water fill issue drain may be siphoning water may be slow filling or bad flow meter flow meter may be harder to diagnois but try tapping lightly with screwdriver (it's the round object left side with 2 small hoses attached ) slim chance may be pressure switch left side rear corner

your dirty water backed up into the washer (which it shouldn't do) and probably clogged something in there,..i would recommend getting it flushed out somehow, not sure how,.....next time, your washer drain hose should go up under the sink as high as possible and then back down to drain,....this settup makes it hard for drain water to go back into washer,....it's instructed in any dishwasher manual
