Question about Bosch 24 in. SHU53 Built-in Dishwasher

1 Answer

Error code 2H

There is an error code 2H when you press the Regular Wash or Delicate/Econo button. Dishwasher will not cycle off. It just keeps cycling on the wash cycle and does not drain. I have to manually reset to get it to drain.

I ran the cycle test and it would not end. The display indicates that it should take about 20 minutes to run the test and after 40 minutes I had to manually reset and clear the program.

The dishwasher does drain on a manual reset.

Any ideas?

The control panel needs to be replaced (indicated by the "2H" error code displayed at the start of the cycle).
BTW - The number 1 displayed at the end of the cycle indicates the cycle has timed out (i.e., it doesn't mean 1 minute remaining). Hence the continued running of the unit. Until you replace the control panel, you'll have to manually cancel the cycle at this point.

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.

2. Release program button.

? If the display blinks with a "0", you will hear
no signal (indicates OFF).

? If the display blinks with a "1", you will hear a
LOW volume signal.

? If the display blinks with a "2", you will hear a
HIGHER volume signal.

Completion Signal has been enabled.

? When you push the button again and it does
not beep, it means that the Cycle Completion
Signal has been disabled.

3. To change the program, press the program
button until the desired setting is selected.

4. Turn the Dishwasher off to take it out of

Hello Dave,

Welcome to FixYa.

Try this test I posted below and let me know what error you find...if any.

To begin the test program, press both the SCRUB WASH and DELICATE/ECONO wash program buttons at the same time

as you turn the unit on by pressing the ON/OFF button. Initially, the control unit version number will appear in the display

(e.g./ 20 = version 20, 21 = version 21, etc.).


When the wash program buttons are released, the LED's above them will begin flashing. To end the test program or test cycle, press the ON/OFF button.


To check the wash program LED, press its corresponding button.


To check the Cycle Countdown display, Refill Rinse Agent LED and REGULAR WASH button LED, press the REGULAR WASH button (press the DELAY START button to test the

Cycle Countdown display alone).


The Cycle Countdown display should show "88" when the DELAY START button is pressed and "8h" when the REGULAR WASH button is pressed.


To start the test cycle, press both the SCRUB WASH and DELICATE/ECONO buttons a second time.


When the test cycle has completed, the Cycle Countdown display will indicate a fault using the codes below. If a combination of faults exists, the code numbers will be added together, (e.g./ 6 = faults 2 + 4).


0 = No faults

1 = Aqua Sensor ("Sensotronic") fault

2 = Heating fault

4 = Filling fault
8 = NTC (temperature sensor) fault

email me at macmarkus@live.ca and I can send you via a "pdf" of the diagnostic/repair manual for your specific Bosch...provided it is indeed a SHU5316 unit.

I`ll watch for your reply. Good luck.

Regards,

Macmarkus :)

Water won't drain


Do the diagnostic test:
SHU 53 MODELS

To start test program, press and hold both SCRUB WASH and DELICATE/ECONO program buttons, then turn unit on by pressing ON/OFF button. Initially, control module version # will be displayed (e.g./ ?21? = version 1 with jumper). When wash program buttons are released, lights above them will flash. To end test program, press ON/OFF button.
To check each program indicator light, press its button. To check Cycle Countdown display, Refill Rinse Agent light and REGULAR WASH light, press REGULAR WASH button (press Delay Start button to test Cycle Countdown display alone). Cycle Countdown display will show “88′ when REGULAR WASH button is pressed and “8h” when Delay Start button is pressed.
To start testing, press both the SCRUB WASH and DELICATE/ECONO buttons a second time. When testing has ended, Cycle Countdown display will show a fault using codes below. If more than one fault occurs, code numbers will be added together, (e.g./ ?6? = faults 2 + 4).
0 = No faults detected 2 = Heating fault 8 = NTC (temperature sensor) fault
1 = Aqua Sensor (“Sensotronic”) fault 4 = Filling fault F = Filling fault (display occurs during wash, not test)
To check for heater, high limit or flow switch problems, start testing until heating starts. Using a meter with a current coil, measure current going into dishwasher. If current is ~ 11 A, then heater, high limit and flow switch are OK. If current stays at ~ 1.5-2 A, then heater, high limit or flow switch are faulty.
If water level switch (f1) has failed (opened), display will show fault code “4′ and unit will continually fill and drain where testing won’t be completed. If flow switch (e5) has failed (opened), display will show “0′, water won’t heat (to 150?F) and water won?t stop circulating. If NTC probe (f2/f4) has failed (opened), display will show fault code “8′ immediately and testing will end shortly after water has started circulating.
---------
The dishwasher not draining is most probably faulty drain pump or drain hose is got bit loose.It has to be checked and confirmed

Error code 2H.....or stops on last minute


I don't think you'll find it's the control board.
I think you'll find it's the heater box.
Not an easy job to do yourself unless of course you know what you are doing.
I would suggest you contact Bosch. One other possiblity is that the water inlet is blocked, although to be honest this is very rare.
