Cycles last too long--Bosch dishwasher

Only two of the dishwasher selections now work--pot scrubber and power scrub plus, but these two take up to 4 hours to run through the complete cycles.

SOURCE: Long cycle times

Many dishwashers heat the wash and/or rinse water to a higher temperature, as the cycle calls for it. In these cycles, the dishwasher pauses after it has filled with water, waiting for the water to reach the pre-set temperature. What happens next, depends, as follows: On some units, the pause is timed and the unit continues after the allotted time. On others, the cycle can't continue until the water reaches the higher temperature. If you have this type of dishwasher and the water isn't being heated (say, because of a problem with the heating element or thermostat), after the unit stops at the heating cycle, it never continues. When you repair the heating-system problem, the "cycle problem" is fixed too. About the led: If your dishwasher has a digital readout and you see an error code, it may indicate a problem with the unit. If this happens, look up the error code in your owner's manual to find out what the problem is.

UNfortunately that sounds like the controle module and you can not have that fixed. only replacement of the part will fix that problem

SOURCE: Bosch dishwasher cycle doesn't end

Try this link, 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 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.

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.

SOURCE: Bosch dishwasher fills with water after cycle is completed

Sounds like you need a new water inlet valve. It's not shutting off completely, so water slowly enters the machine even while it isn't running.

It sounds like there's a problem with the dishwasher's heating element. The dishwasher uses the heating element to heat the water to certain temperatures, and it will wait (run for extra time) for the water to reach this temperature, and may eventually give up. When it's time to dry, the dishwasher uses the heating element to steam dry the dishes. If you're not technically savvy, you will probably need to have a pro work on the machine, but first check to make sure there's not hard water scale buildup on the heating element. If you're brave enough to work on the machine, you should check to see if the element's plugged in, check its resistance to make sure it conducts electricity, check the element's switching components, and finally the dw's computer board. There's a chance that the machine is just stuck in a loop or something. You should try turning off the circuit for a few minutes. There's a chance it may reset and start working.

The issue with your Bosch dishwasher 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 ). This is the purpose of the "1" indicated in the display, a heating problem.

I`d first suggest calling in an authorized bosch servicer, however If you feel capable there`s a way to visually inspect the control. 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 at "1" ( because it can`t heat to advance or until canceled ) trying to heat the water.

**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 there 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. If you do not feel comfortable attempting this service, call a local pro, preferably one familiar with Bosch/Thermador/Gaggenau, to service your machine.**

Hope this answer`s your question, 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 and leave a testimony.

Good luck.

How do we put it through a test mode?

Here you go, both answers :>)
Bosch Dishwasher Troubleshooting Your Bosch dishwasher can run a test cycle which will quickly go through each stage of a wash programme in order to find out at what point a fault is occurring. It will only give you a general idea of where the problem lies but is a useful first step in diagnosing the issue.

The steps to start the test cycle vary depending on what model you have but the basic method is similar across the range. It might be that your dishwasher doesn't have the same button labelling as described in the steps below. In that case try holding down the buttons which have similar names. After a little trial and error you'll find the right combination.
  • Make sure the dishwasher is switched off.
  • Press and hold the Power Scrub Plus and Regular Wash buttons.
  • Turn on the dishwasher, then release the two buttons.
  • The light above each of these buttons should flash.
  • Start the test cycle by pressing the Power Scrub Plus and Regular Wash buttons again.
  • The test programme will begin and an error code will be displayed at the end of the cycle if a fault has been detected.
You can find a list of Bosch dishwasher error codes and their definitions here.

How to run self test on bosche dishwasher

Here is an excerpt from "Bosch Dishwasher Troublesoooting".

Running a Test Cycle
Bosch dishwashers have a test cycle which can be run as a troubleshooting measure. The method to run this test cycle is similar across the Bosch dishwasher range so if your dishwasher features seems different from those described below then try experimenting, as the process is fairly straight forward and will be very similar. Bosch dishwasher model numbers are usually found around the top or lip of the door. One of the most common differences between dishwasher models is simply the names of the buttons. For example in the first example below, POWER SCRUB PLUS and REGULAR WASH may be called WASH and ECO depending on your dishwasher model and the country you are in. The other key difference is whether your dishwasher has a display panel (which can display error codes) or not (in which case a program light will illuminate to tell you the fault.
To run the test cycle hold down the POWER SCRUB PLUS and REGULAR WASH buttons. Whilst held down press the ON/OFF button. The lights above them should flash. Now you can check the status of each dishwasher program by pressing its button. Now you can run the full test cycle = Press the POWER SCRUB PLUS and REGULAR WASH buttons again. The dishwasher will start up and when the cycle has ended one, if you have no display panel on your dishwasher model the indicator lights will illuminate if a malfunction was detected as follows -
CLEAN - A temperature sensor fault. If this is the case then the test cycle will be very short as the dishwasher will terminate the test once it's been detected.
RINSE/DRY - A water sensor/filling fault. If this is the problem then the test cycle will not complete as the dishwasher cannot detect the right level of water, the dishwasher will just keep filling and draining again.
WASH - A heating fault. Check your heating element.
If you do have a display panel on your Bosch dishwasher then after the cycle is complete an error code will be shown if a fault has been detected. The error codes are as follows -
0 - No errors have been detected.
1 - A water sensor/filling fault.
2 - A heating fault.
4 - A water filling fault. This can also appear as F on the display during a normal cycle.
8 - A temperature sensor fault.
When troubleshooting your Bosch dishwasher, running the above test cycle is a good start in diagnosing the problem and should give you an idea of where the problem lies with your Bosch dishwasher and what fixes and repair are in order. Our general troubleshooting page will give you some ideas on other things to check on your dishwasher. Good luck!

Replaced the control board in Bosch Dish Washer SHE44C and the cycle times are reversed???

I think this board requires coding to your particular model?? your dishwasher has four selection button and a delay start, whereas the module has five selections and delay as it is used in several different modesl. The coding info should have been in the box with the part and may need to be carried out directly on the module with the fascia panel removed. If you post the part number of the module I will see if I can get you the coding information..

No water is coming in and its almost like it is 3/4 of the way through the cycle and stuck in the same position.

If the wash motor continuous to run but the cycle is frozen then most likely the thermostat or heater is faulty. Try to run one of the short cycles like rinse only to confirm if the cycle is completed.

Bosch dishwasher model SHX46A why does the on/off switch and lights stay on while the dw stopped running?

The dw was not quite running. It does pause between cycles. The power scrub cycle means that you had the machine on the longest of all cycle choices. There's almost always a light and a normal cycle. The pots and pans cycle is a power scrub option. Yes all the lights would be on until they switched to a different part of the cycle. Do you have a DRYING light? That would be the one to look for as far as the dw being finished. :)

I need to know what the buttons say on the dishwasher. Mine have no letters


Some SHX46 washers have 4 wash cycle buttons and others have 5. The button on the left side on top of the door is the start/stop button regardless of how many wash cycle buttons you have.

If you have 5 cycle buttons, reading from left to right they will be as follows.

1. Top Rack Only / Sanitize
2. Power Scrub Plus - (Long wash for heavy soil)
3. Regular Wash - (Economy wash for light to medium soil)
4. Delicate Wash - (Shorter wash at a lower temperature for delicate items)
5. Rinse & Hold.

These buttons are also used for cancelling a wash cycle. Hold down buttons 2 and 4 (Power Scrub Plus and Delicate) at the same time to cancel a wash cycle and drain the water out.

If your washer does have 4 buttons, it means you don't have a Top Rack / Sanitize cycle, in which case the button configuration - from left to right - will be:

1. Power Scrub Plus - (Long wash for heavy soil)
2. Regular Wash - (Economy wash for light to medium soil)
3. Delicate Wash - (Shorter wash at a lower temperature for delicate items)
4. Rinse & Hold.

With this button configuration, the cancel cycle buttons are 1 and 3.

I hope this solves your problem. If you need any additional information, please post back.

I have a Bosch SHX46A05UC/33 5-cycle dishwasher whose labels on the cycle buttons have also worn away. While the Macmarkus post was helpful b/c I have some of the same buttons, can you tell me the labels...


Some SHX46A washers have 4 cycles and others have 5 cycles.

I'm fairly sure your model has the hidden buttons on the top of the door and you stated you have five-cycle buttons, in which case they will be as follows.

1. Top Rack only cycle or Sanitize
2. Power Scrub Plus
3. Regular Wash
4. Delicate Wash
5. Rinse and Hold.

These buttons are also used for cancelling a wash cycle. Hold down "Power Scrub Plus" and "Delicate" at the same time to cancel a cycle and drain the water out.

If your washer does have 4 buttons, it means you don't have a Top Rack / Sanitize cycle, in which case the button configuration (from left to right) will be:

1. Power Scrub Plus
2. Regular Wash
3. Delicate Wash
4. Rinse and Hold.

I hope this solves your problem. If you need any additional information, please post back.

New Bosch dishwasher mold before cycle

The Bosch is a very good dishwasher and it is very airtight. I would suggest you NOT leave the dishes inside that long, and always use the Power Scrub Plus cycle if you have it. It will get the water as hot as possible so mold does not continue to grow in the plumbing and filters.

It is NOT the dishwasher unit causing the problem.

Bosch Dishwasher stuck in "Scrub Cycle"

The Control module on our SHU43 blew this morning and when I took it apart to get the module out, I discovered why two of the Cycle selections no longer worked..... the little plastic lever that pushed the switch behind the fascia button - had broken off. You may have the same issue. It's not a cheap fix though as a new module is gonna cost me $175.
