Question about Bosch Dishwashers

Open Question

Bosch SGS5312GB/12 Dishwasher I had a control board. Worked fine except didn't heat the water. Got it repaired (new PCB). Now the only thing it does is drain. Clicks every 20 secs and carries on draining. Got a new board. Does everything (including heat the water) except it does not drain before, between, or at the end of cycles. It does drain when while filling, and if the flood detection rod is raised manually (also drains if the inlet pipe beyond the pressure sensor is blocked - found that out by accident after clearing sludge from the pressure sensor which caused incoming water to back up). Suspect it's a board fault (with both repaired and new boards - different faults), but also concerned that it might be a stuck sensor which is causing different behaviour in the boards.

Hi John I have the same problem, the manual says that it is because the water level is to low, this is checked by opening the door after the machine has stopped filling and before it starts to wash, the level should be 4mm above the main plastic filter ring, the level has two settings, these can be adjusted by pressing the start button and the On/Off button at the same time, release the start button and turn the control to economy 45,if the start light does not come on the level is set to normal, to increase level press the start button again and the light should come on, this will give you an increased filling time. it did no help me but it may help you. good luck

it sounds as though the circulating pump may not be operating. if so fault is often due to the pump capacitor being faulty and this is a cheap part.

I f you have warranty on this please call them, you have a defective D/W.Unless there is no charge for repairs ,don't spend a dollar on what is going to be a on going problem ahead.To explain how to fix this is what the manufacturer should have done in the factory and not made 1 dollar off of this defective D/W until it proved this to be ready .What has happened to Quality Control ? Does it no longer matter ? Very sorry ,you should seek a refund ASAP.

SOURCE: Bosch SHU9925UC Dishwasher Stuck in Initial Drain Cycle

OK Bosch Dw fans.........here is the fix if your SHX dishwasher is stuck on the drain cycle. This may save you a couple hundred bucks.......so listen up. There is a tendency for the very small float switch to STICK in the ON position, which will cause the drain motor to continuously run......and DISallow any other function to work. DISCONNECT POWER. Did I mention to disconnect power? Take off the front base cover....2 torx screws. Remove the other 2 torx screws in the metal clips that fasten the top of the DW to the underside of your countertop. NOW...carefull slide your DW out. You may have to disconnect your water and elec supply if you do not have enough slack to pull it out. Once the DW is out of the cabinet, remove the shiny metal cover on the LEFT side by removing a single torx screw. You will now see a small plastic assembly with a red plastic piece that moves up and down as it rides on a small red styrofoam float. This up and down movement engages a small white plastic switch visible with 3 wires coming out of it. You can carefully UNSNAP this switch out of its mount, and pull the 3 wire plug off of it. THere is a small square blue plastic tab that is supposed to easily slide in and out of the switch. If it is stuck IN, you can sometimes tap the switch and the blue tab will pop out, which is what it is supposed to do without tapping it. You can carefully with a knife blade separate the case on this switch and note the way it comes apart. Clean out any micro debris out of the small channels that the blue tab ride up and down in. Then set it in the channel while holding up the small switch tab that rides on it and see if it slides up and down without sticking! I like to take a piece of wax paper and rub in on the channel and blue tap to provide some lube for the switch to slide easily on. Now, put the switch back on and manually move the red plastic assembly up and down while you are watching the blue tab. The tab should ride up and down with the red assy. If not, buy a new switch. Google the # on the switch and order one. If the tab slides up and down, put things together in reverse order and give it a try. Hope it works for you. This should take you an hour give or take. Take the $200 you just saved and have a night out on me. ........so even though these German Appliances have a good name because of past reliability, the american tendency to value engineer them with plastic parts to reduce costs and increase profit.........just cost you an hour of your time. Will we ever learn.? ......if it ain't broke, value engineer it until it only lasts through the warranty period so you can then collect service and parts blood money from your fellow american.

Dishes won't dry Bosch SHU43


Hello, welcome to Fixya.

I know this post is a few days old, but in the event you haven't found a solution yet I'll throw my 2 cents into it.

I just want to clarify one thing you mentioned in your post about a setting "1" for extra drying, I've been working on B/S/H/ ( bosch thermador siemens gaggenau ) dishwasher's for a long time and this is new to me.

I suspect the "1" is actually an error code and not coincidentally the reason it doesn't dry.

Here`s the most likely reason why it has detected the error...

Even if your home water supply appears hot, it's not hot enough and must be heated by the dishwasher to insure a proper clean and dry, hence most if not all manufacturer`s do this.

When it comes to your Bosch dishwasher the problem likely lye`s within`the electronic timer/control, specifically the heater relay solder joint. ( a faulty flow switch, ntc or heater can also cause this, but not very probable ).

To repair your unit It will require you to remove the control from the unit and then remove the control from it`s plastic housing and look for a burnt solder contact on the printed circuit board. This will be one of the pins from the heater relay, hence the unit sit`s and display`s the error "1" telling you it can`t heat the water.

( I can send you documentation directly from B/S/H/ confirming and explaining this if you'd like to post your email address ).

**Further to this, if you or someone you know is proficient at soldering, a lot of times it can be remedied by simply repairing the solder...although Bosch recommend`s replacing the control and I don`t pretend to speak on their behalf nor do I profess to know better. This is just my experience (it work`s) and my opinion (why buy new if one can repair ?)**

**Please disconnect the power before attempting any service to the dishwasher**

Installing a new control will certainly remedy the problem as well. But when it is priced at about $170.00 I am more likely to offer someone an alternative to buying new, hence my first reaction to mention this repair tidbit.

The control is available at most brick & mortar appliance parts stores or on-line at vendors such as "repairclinic.com", "apwagner.com", "searspartsdirect.com" etc. part number is based on your specific model number so you`ll need to provide that.

Hope this answer`s your question's, let me know if I can assist you further. Thank`s for visiting "fixya" for your repair inquiries.

Please take a moment and rate this solution to it's helpfulness to you and leave a testimony if you're satisfied.

Good luck.

Bosch SHU 3032 dishwasher gets stuck halfway through the wash cycle and just continues to wash until you manually advance it. I turned in on before bed one night and it was still running the next morning....


Hi,
It obviously sounds like a timer issue here, and as it's embedded in a big chip on the control board, I would think a new control board is needed.
The exception to this is if it is not heating at all, in which case it won't advance if the water is not hot enough. Try it again and see if it gets warm.
If not - replace the heating element.
Most machines just stop to heat up the water, but to cut down cycle time they may recirculate the wash-water first to speed things up.

What is error code 2H


My Bosch dishwasher did the same thing. When the wash cycle starts, the dishwasher fills with water and then the heater is supposed to turn on to heat the water. If the water does not heat, then it will display 2H continuously. The heating element may be bad, but a more likely cause is with the control module. Bosch has a problem with the control module printed circuit (pc) board that powers the heater on many models. The solution requires some technical expertise and soldering skills. The details are explained in the document "Bosch dishwasher troubleshooting tips" on page 11. Download here
Bosch recommends re-soldering the connection, which is a temporary fix. The problem is that the copper conductor (called a trace) on the circuit board is not wide enough to handle the current required for the heating element, and as a result the copper trace overheats, causing the solder to melt on the relay connection. The best solution is to remove the control module PC board and solder a short length of copper wire between the pins to prevent the overheating problem, as shown in the attached photo (magnified portion of PC board). I did this on my dishwasher and it has been trouble-free for over 3 years.

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

Bosch Dishwasher Water Not Heating


Depends on if it is the controller board (easy, just behind the door and requires a torx 20 screw driver) or if it is the heating element. The latter is easy, but time consuming, as it requires you to pull the dishwasher out, detach the bottom, tilt it on it's back, and remove pump,etc to get to it. Not difficult, just a bit time consuming.

Bosch dishwasher cycle doesn't end


Try this link, http://www.applianceaid.com/boschDW.html for procedures for running self-tests on various Bosch models using the front door switches. Find your model and read and follow the procedure.
This remaining at '1' problem invariably relates to a 'heater fault' which has usually been traced to an open solder joint on the control board located behind the switches/indicator lights on front door. See pic here of open solder joint http://www.flickr.com/photos/zenzoidman/145089572/ In most cases, the heating element has not been at fault.
I got mine going again by resoldering the joint and saved ~$300 in parts & labour. If this is beyond your skill set, then replace the control board assembly, 266746, which is used on multiple Bosch models. See this page for more information if you want to try to DIY. http://www.appliancejournal.com/appliance-parts/bosch-appliance-parts/bosch-dishwasher-control-module-266746-37/

If this is still beyond your skill set, then call a tech & supply the Bosch model, serial number, and the results of the self-tests.
