Question about Bosch Dishwashers

Open Question

Bosch SHU4302 WITH REPAIRED PC BOARD has been working fine for several years now seems stuck in rinse/drain mode and is not quite pumping cabinet dry. I have removed the screens and located the small impeller at bottom below cover. The impeller rotates as though it has multiple spring loaded stop positions. When I turn on the unit and open the door water is trickling from the sprayer arms at low pressure. It seems stuck in rinse mode and will not advance cycles or reset when shut off.

SOURCE: Neff S5555 - empties water but stuck in draining mode.

if this machine uses an electrical-mechanical timer with cam switches, the try oiling the shaft bushings both for the timer motor and cams-the timer may be getting stuck because of dry or corroded bushings

SOURCE: Bosch Dishwasher Not Draining

Im really not all that familiar with the bosch unit, but a few things i would ck. when you cancel a cycle (it should drain the water) is it humming??? does it sound as if it even trickling into the sink discharge?? do you have a disposer under your sink that this unit drains into, if so remove the clamp and look for possible obstructions right there.Honestly passed this ill have to defer to someone else sorry and good luck

SOURCE: upper sray arm does not turn

If the filter is clogged than stop here. If it was not clogged then Im assuming you replaced the actual spray arm.You have a problem either your water level is too low or your spray arm is not making full contact where the arm elbow meets the tube running down the back wall inside.Check for improper alignment of upper spray tubing.
Please rate this!

SOURCE: LG LDS5811WW Low pressure out of spray arms

On the LG LDF xxxx dishwasher family, the Vario feature uses a motor/check valve to switch between "full power" cleaning from _either_ the lower or the upper spray arms, never at the same time. So, not seeing the upper arm spin during the lower arm spinning is standard operating procedure.

But back to your problem. Step one would be to remove the filter assembly again and make certain that there is nothing (debris, broken glass) blocking the white areas where the check valve rotates to switch between upper/lower spray arms. A blockage there ~could~ cause impotent spraying/cleaning.

If there is no blockage and the impeller remains in good shape, suspect a failing wash pump motor. Try to isolate the noise to that motor.

Watch for error codes on the display and report back what you find, OK?

Good Luck!

Bosch dishwasher runs continuously


I would call Bosch with you.re model and serial number, they have had a recall on your model for the control board and that sounds like it may be your problem, if it is under recall Bosch will send someone out at no charge to install a new board (800) 856-9226

My boosh dishwasher is stuck in rinse and wont drain, but when i press cancel on the washer the water drains.... whats causing this????


There is a chronic problem with Bosch dishwashers where the heater relay is soldered to the printed circuit board becomes loose (actually it seems like the solder just disappears from the connection).
You may also note that the timer seems to get stuck and will not advance.
Remove the top front panel, the circuit board is on the right side as you face the dishwasher. You need to re-solder the heater relay terminal.

My Bosch diswasher water inlet work fine, when the wash motor or cycle need to start nothing happens. The timer is advancing normal. Water outlet(drain pump) is also working fine. There is no woosh sound...


Hi, it sound's like the wash motor is either seized or just stuck, let's hope it's the later. Bosch had issued a service tip about this problem several years ago titled "Loosening Frozen Impellers" strange choice of word's considering nothing is froze..at least you'd hope lol. I have a copy of it at home and I can likely post it later, ( I'm on my iphone presently ) but essentially what it say's is this...Remove the pump fitler ( inside the tub under the bottom rack ) locate the hole to your right down in the sump well, you should be able to see it with a flashlight or well lit area. Once you've located this hole ( it's providing access to the wash impeller without pulling the unit from the cabinet ) reach in with a 8mm nut driver and locate the end of the impeller and turn it clock-wise until it feel's to turn freely. Give it a test perhaps in a rinse cycle before you put all the filter and screen back together. It should be fine unless the motor is seized, we'll cross that bridge when we get to it, try the repair tip for now. Let me know how that help's and/or if you need further assistance. Thank's for visitng "fixya" for you repair tip's. If this is indeed helpful please rate the solution accordingly, if not, again please let me know. Thanks again and good luck. Macmarkus :)

Bosch SHU4312 won't finish cycle, won't drain.


The control board on these units is prone to a cold solder joint cracking. I have read that Bosch recommends replacement and will supply the board, not covering labor. I repaired mine prior and have done one for a friend as well. Has lasted several years and counting
The symptom is constant cycling without ticking down the last few minutes

Pump motor cycles


If you are still having problems, providing the serial number is actually important because of a retrofit to several items in the door panel. Which could actually be related to your symptom.
Please provide the serial number or report back what you did to resolve the problem. Thanks!

Bosch SHU43C


My SHU43C is just over 3 years old. I had a similar problem recently. First, there were a few floods. Then, the Bosch only drained non-stop. Even when I used the Cancel Drain buttons the drain pump would run without stopping. When I tried to run one of the cleaning cycles, no water entered the machine. Corrective: I removed the base plate, and saw that the red plastic floatation device was in the up position. Using a flashlight and a wooden spoon, I lightly toggled the red float stem down. I pushed regular clean cycle and kept toggling with the red float stem until the rinse water started to enter the machine (turning the red stem seems to also actuate a step in the program). Now the dishwasher runs normally. Voila!
