Question about Bosch SHU5307UC Built-in Dishwasher

Prolonged washer cycle time

My washer is taking too long to complete. The "delay start time" keeps popping up with 2H, which I think means 2 hours delay. I have tried resetting the washer. I have adjusted the delay time to "0 H" which I assume means zero hours delay. But it keeps resetting back to 2H. What can I do to get it back to normal?

Re: prolonged washer cycle time

Hi! I'm not familiar with this model, but it sounds to me like there is not a problem! If you set the delay time to 0H, switch off the unit at the main switch, then switch back on. If there is still a 2H displayed, it means that the PROGRAM that you have selected will take 2hours! This is fairly common for the Bosch units on the 50 - 65degC cycles...some models have a "reduced washing time" button - it looks similar to the "delay" symbol, but once pressed, it reduces the washing time by almost half (cuts on rinse cycles) If your model does not have a reduced time button, select a shorter cycle (35/40/50eco), and see if the time is less. Remember that the latest dishwashers are engineered to be more energy efficient and water wise, so they had to lengthen the wash cycles in order to get good wash results! Hope this helps! C.

Re: prolonged washer cycle time

I've had this problem a couple of times, and the culprit was a bad control panel. Last tech to replace it said that if you go to run it, and 2H comes up automatically - the control panel needs to be replaced.

Re: prolonged washer cycle time

These dishwashers are notorious for burning a solder connection on the control board. If you can get the board out and can solder, you can fix it yourself for free. it will be obvious where the problem lies once you open the control board housing, if thats the issue. Otherwise it sounds like you will have to replace the board. Unless of course this is the way it's always operated, but I doubt you'd have posted this if that was the case. Good Luck

My gaggenau dishwasher GM 954-110 is not working. when i switch it on the display panel shows 2H.

Hello, welcome to FixYa.

The dishwasher you're speaking of (provided it is indeed a Gaggenau GM954) is built by Bosch as you may or may not know.

To address your concern regarding the 2H in the display actually needs to be done in two parts. I'll start with the basic info associated with the 2H displayed.

This can be simply indicating the previous cycle exceeded a 2 hour wash cycle, not necessarily an error and can be attributed with too cold water entering the dishwasher (below the recommended 120F), a longer than normal drain time (due to partial blockages, kink etc. hence longer time needed to complete the cycle) or inproper water circulation during the cycle.

Aside from these issues, it (2H) can also mean the unit has a heating error and if left long enough will show another error of "1" in the display, extremely long wash times, etc.

**The first thing I'd suggest before attempting any repair is running an additional cycle while making sure the water inlet is hot (120F optimum) and the unit does indeed drain fine.

**A fair indication of proper draining is to start a cycle and once washing begins (2-3 minutes) activate the "cancel" and the unit should adequately drain in the 2 minute time allowance.

**To identify proper water circulation, place an empty cup in the upright position in the top rack, start a cycle and inspect the cup after 2-3 minutes and it should be full of water.

After trying and posting the results of these thing's we can move forward with potential heating errors, the cause, and how to remedy them. Let me know what you find and I'll continue to assist you in any manner possible going forward. Good luck.

Dishwasher ran all night still not finished. Error code 4H displaying.

Hi and welcome to FixYa. I am Kelly. The 4H is indicating your dishwasher is in the delayed wash start mode. Here is some information from Sears about what to do:

  • The number letter combination indicates that the dishwasher is in a "Delay Start" mode, as well as how many hours were set for the delay start.
  • The dishwasher will not start the wash until it reaches the delayed hour that it was set for. Example: 1H = 1 hour delay start, 2H = 2 hour delay start, etc.
    • To start the dishwasher immediately and not wait for the Delay Start time, cancel the "Delay Start" option, by pressing the Cancel button. Then program the cycle and options and press Start.
    • To start the dishwasher after the Delay time, select the cycle and options desired. Select the "Delay Start" option and on some dishwashers it requires, pressing the Start button.
    • Some dishwashers will display a countdown of the delay time on the display.
Note: Refer to the Owner's Manual or Use & Care Guide for specific instructions on using the "Delay Start" feature.

If you need more assistance we will need your exact model number in any of your future responses.

Beeping sound when cycle is finished just started after 8 years. how do I turn it off?


Welcome to FixYa.

I think can answer your question..."beeping sound when cycle is finished just started after 8 years. how do I turn it off?"

Follow these steps...

**How to Operate the Cycle Completion Signal**

1. Open door, hold down program button (see
Beeper Table below) and simultaneously turn the unit "ON".


SHU 9950 Delay Start Hours
**SHU 9910-9920 Delicate/Econo** should be yours
SHU 8800/8810 Quick Wash

SHV 6800 Delay Start Hours
SHV 4800 Delicate/Econo
SHV 4300 Delicate/Econo

2. Release program button.
a. For SHV 6803 and SHU9950 models:
The display will blink with a code of "0", "1" or
"2". You are in program mode.

? 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.

b. For all other models with the beeper

? If the machine beeps, then the Cycle
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
program mode.

* At the end of a wash cycle, the beeper will sound
off two times, and again every 15 minutes until the
dishwasher is turned off.

Hope this answers your question and provides you with what you needed.

Thank you for choosing FixYa and good luck.

Please take a moment to rate the solution provided and a short testimony if you feel it's warranted, but also let me know if you require further assistance.

2H accures in digital read out. NO Cycles start, just a humming

Do you own an LG LDF6810ST dishwasher? If not, please reply with the manufacturer name, model and serial number.
Are you saying that the display that normally shows the time is displaying an code of 2H? On an LG, that means 2 Hours, (120 minutes) and is not an error code.
On an LG with a symptom like this, I would arrage to replace the main processor card (PCB). You would be getting an error message if the motor (wash or drain) had failed.

Can not reset the ''delay cycle'' timer

I would call that service company back and ask for your money back first of all if he didn't fix the problem. That code probably means a failed circuit board.

What does the 2H mean? It seems to be the "standard" but the manual has no definition.

Great question!
2H means 2 hours -- 120 minutes ... the display only has 2 digits so it can not display 120 minutes. When the timer gets done near an hour an one half, it will start to display a countdown somewhere near 90 (minutes)
Yes, the cycles are long on the LG LDFxxxx dishwashers, just like all water and energy conserving dishwashers.
This really is a good dishwasher, recommend you keep the rinse aid dispenser filled up and ALWAYS use a brand name powder (like Electrosol or Cascade.) Also make sure when it was installed, it was properly leveled.
Hope this helps!

Problem with Bosch built-in Dishwasher Model SHU6806UC

I had the same problem and just today replaced the control board module. Purchased the control module online and installed in myself. Was not that difficult. undo the screws (torx screw driver needed) unhook the connections to the board and label all. Pull the board out and open, found burned connectors. Now works like a dream.
