Re: runs program but stops on 1 minute left and needs...

I have this problem quite regularly with my NEFF built-in dishwasher. It can have a number of causes, but in my case it is almost always due to a sticking float in the filling system. This causes the machine to underfill so it doesn't clean properly and then sticks with 1 minute left to run for ever. Other machines are probably quite similar - especially Bosch and Siemens.
My solution is to :
1. Disconnect electrical supply and turn off the water. Slide the dishwasher out of its housing carefully (you made need to disconnect hoses and mess with the levelling feet and other fixings to do this)
2. Remove the decor panel from the front door (usually two torx screws 2/3 of the way up each side - just loosen them)
3. Take the left panel off the dishwasher. Have a look at the filler float / air pressure chamber mechanism. If it all looks black and gungy inside, then this is probably your problem (It's slime mould that seems to love to collect here and jam stuff up). It may be possible to clean it in situ using hot soda or vinegar (someone else has put a youtube video about this here: ). If that fails though, you will need to remove the entire float chamber mechanism to clean it out.
4. Take the bottom panel off (below the door.
5. You need to remove the water matrix reservoir. Remove the clip securing the water inlet to the matrix (back lower left, narrow pipe - blue in my case) and pull the pipe off (have a towel handy - it'll dribble quite a lot)
6. Pull out the clip between the two corrugated pipes next to the water inlet pipe, then pull these two pipes away from the water matrix. (towel again!)
7. Peel away the plastic splash shield carefully to expose the wiring to the micro-switches. Double check you unplugged the machine, then pull the two connectors off the switches.
8. Remove the two metal rails holding the matrix to the side of the machine (one torx screw in the middle of eash rail) and also remove the two top retaining clips (front one just pulls off and the rear one is held with the self-tapping screw accessible from the back)
9. You should now be able to lift the entire water matrix clear of the machine (there are 3 water connections at the bottom - these just pop out. Take care not to lose the rubber sealing rings). And you'll need that towel again. And maybe a bucket! And a good excuse for why the floor is all wet. (allright, I exaggerated a bit there)
10. Disconnect the lower drain hose from the float assembly - you need to get at this through the lower front panel.
11. It should now be possible to ease the float assembly up and away from the machine. Watch out for the red push-rod that operates the anti-flood device from the polystyrene float in the base.
12. You now have a (fairly slimy) pressure chamber assembly in your hand. All the parts of this simply unclip with a bit of effort. Take case not to break any bits, but basically anything that's a different color is detatchable. Clean everything (except the two microswitches!) in warm soapy water. An old toothbrush can help. If there is any lime-scale build-up, use a lime-scale cleaner too.
13. Before you put if back together, check the base of the machine (where the polystyrene float is) for water. If present, soak it up with a sponge or paper towels.
14. Now put it all back in the reverse order. REMEMBER THE ANTI-FLOOD float/push-rod assembly. I forgot and had to take it all apart again.
15. Water on, plug in, cross fingers and try it!
16. If it still messes up, check for water in the base again - you may have a leak from somewhere else causing the anti-flood to operate. ( In this case though, the machine will normally just continuously try to empty, rather than even attempt a wash cycle.)

Good luck.

Re: runs program but stops on 1 minute left and needs...

To be honest with you i ended up taking it to the local dump because i was under pressure from the wife as she was concerned about the items not being cleaned properly and also if left unattended for a long period of time was it going to be a fire hazard?? but saying all that i was kind of happy leaving the door open once the wash was completed to leyt the dishes dry naturally. it's your call but in a nutshell no i didn't fix my one. good luck dave

Did you manage to solve the problem with your dishwasher. I have the same model and it keeps sticking on 1 minute at the end of the cycle. Any advice please?

The dishwasher doesn't finish the 30 min program. The display shows 1 minute remaining but the washer doesn't stop.

It sounds like the d/w has a heating issues. Possible internal failure of the heating relay.

I have a SHU5305us/u12 and my front door lettering got erase. anyone have a picture or a manual that tells me what each button means.

Cycle Interruption

As a safety feature the dishwasher will automatically turn itself off whenever the door is opened. However, if the door is opened quickly while in a wash or rinse cycle some water may splash out of the dishwasher. For this reason it is recommended that the machine always be switched off before opening the door.

To Interrupt a Cycle

1. Press the on/off button to stop operation.

2. Wait at least 10 seconds (or until the water noises stop) before opening the door.

To Resume a Cycle

1. SHU/SHI models, close the door and press the on/off button.

2. SHV models, push the on/off button and close the door.

Changing a Cycle

For Bosch dishwasher models SHI 6800 and 4320, SHU 5300, 5310 and 6800 press the program button of the desired cycle TWICE. For all other Bosch dishwasher models, press the program button of the desired cycle ONCE. The chosen cycle button (or the light above it) becomes illuminated, showing that it has been selected.

* SHU 3030 and SHU 3130 models do not have program lights.

Cancelling a Cycle

Each control panel shows which buttons to simultaneously push to cancel a cycle. Refer to your dishwasher to find the cancel drain buttons on your particular model.

1. Press the indicated buttons at the same time and hold for approximately 3 seconds.

2. When the drain pump noises stop and the LED display or clean light indicate that the end of the cycle has been reached, the dish

washer is reset.

3. Press the on/off button to turn the dishwasher off.

4. The dishwasher is now ready to run a selected cycle. Add more detergent if necessary.

Cycle starts, but does not fill with water

When I start a new cycle, I first hear the pump run to empty out all remaining water, and after that I hear the motor run for the regular washing cycle, but there is no water in the dishwasher. After a few minutes, the cycle stops, and the washer claims the dishes are 'clean'. When I try starting a new cycle over and over again, about one in 20 times, the cycle will run normally with water. But then the next time, the problem starts all over again. Once a cycle starts correctly, everything works fine, including the rinsing.

Dish washer does not turn on CL light stays on when reset count down 6 appears then goes to CL

Hello and welcome to Fixya,

I have a ton of service info on Bosch so it`s best I post you an exert from the service pdf`s I have on my PC which will explain the meaning of "CL" and then go from there. This is not a common indication of a control problem, but it could be a problem with the plastic casing which houses the control, we`ll deal with that later.

I`ve underlined the section pertaining to the "CL", this is for the SHU68** dishwashers only.


First depress the On/Off Button until it locks in place.

Once the On/Off Button is depressed the LED above the previously used cycle will illuminate.

To change the cycle, simply press the desired Cycle Button twice. The LED above that cycle will then illuminate.

The Cycle Countdown will display an approximate run time for the cycle chosen.

This run time will depend on incoming water temperature and the turbidity of the pre-wash water.

Note: It is normal for the Countdown Display to remain at a time increment for more than one minute, or skip a time increment depending on the calculations of the Control Unit. Also, with continued use the Control Unit will learn the wash and temperature patterns for the most commonly used programs and will then reduce the overall start and running times.

At the end of the cycle the display will show a CL, indicating that the cycle is complete.

Press the Scrub Wash and Delicate / Econo Buttons both in at the same time. The unit will then drain and the figure CL will appear in the display.**

The Delay Start feature allows the unit to be delayed for up to nine hours. To program, start the unit as described above, but after selecting a cycle push the Delay Start button. The display will show a 1h, or one-hour delay. Continue to depress the Delay Start Button until the desired delay time is reached (up to nine hours, 9h).
The unit will begin automatically once the delay time has elapsed. To reset the delay, press the Delay Start Button until it reaches 0h.

The Top Rack Only feature can be used in conjunction with any cycle. To active, press the Top Rack Only Button after selecting a
cycle, the Top Rack Only LED will illuminate and all water will be diverted to the upper wash arm for the complete cycle.

The Refill Rinse Agent LED is activated via a Reed Switch on the Detergent Dispenser, Section 4, Fig. 8-3. The LED will
illuminate when the Rinse Agent Dispenser is empty.
Service note: The Refill Rinse Agent LED will also illuminate when the dishwasher door is opened and then
closed even if the Dispenser is full, but will only remain lit for a few seconds.

An “F” in the display window indicates a filling fault.

Please note: If the door is opened during the cycle, the On/Off Button will be reset to off and must be depressed again to re-active the cycle. The cycle will resume from where it left off.

Now that you are equipped with this info, what I`d suggest is trying the **cancel option. ( ** see above )

Once you`ve tried the cancel option, select a Regular Wash and post back what happens and I`ll try to assist you from there.

Good luck.

Water left in compartment

You need to elevate your dishwasher drain hose under the sink. The water going down your disposal side is running down the hose into the dishwasher.

What is causing the drain pump to continue running

C1 - Partially Blocked Drain - This error will occur when dishwasher was unable to pump out water in less than 95 seconds. Check drain line for debris and blockage. If clear, check for a restricted drain valve in the pump. Check the pressure sensor for correct operation as it sounds like it may be defective and thinks that the machine is still full of water after it has emptied.

Whirlpool gold dishwasher gets stuck at 53 minutes left for an hour

Try "resetting" the control board by running the diagnostic cycle. The cycle completes in 15 minutes. 
The details are in the service manual. The manual can be found hidden behind the tow plate (at the very bottom front of the washer).
The diagnostic cycle may tell you the problem. It also helps clear up some of the software gltiches. 
It is easy to run the diagnostic cycle.
Just the buttons in the following sequence. The sequence should be complete within 6 sec. 
heated dry -> Normal -> heated dry -> Normal
This will trigger diagnostic cycle of 19 intervals. Pay special attention to the intervals 18, 17, 9, 6, 4.
Interval 18 - displays your controller module number (should be letter 'd' followed by number 0 or 1 or 2 or something. Note that down for future reference.
Interval 17 displays 'software generation number' Note that down for future reference.
Then wait until you reach interval 9.  --- clean LED turns on - then an open or shorted thermister is detected.
-- Sanitized LED turns on - then the washer detected greater than 100 deg F temperature
Interval 7
-- Soaking/sensing LED should NOT come on (unless food soil is present).
Interval 4 -- Soaking/sensing LED should come on

Let the cycle complete and then try running the normal wash. Hopefully the possible glitches are cleared by now and you should have no problem. 
If this doesn't work, time to call the expert tech.

Error code 2H

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.

Stuck on last minute

I have seen a lot of these dishwashers burn out the control board, and usually the symptom is the timer not working or inability to complete a cycle. Most of the ones I have seen, you can remove the control board assembly and its pretty obvious where its burnt. If you can do the repair yourself, the board is about $150. Hope this helps!
