How do I reset the code.the lights are lit 4 hour delay, rinse only steam clean.

I would try turning off all power to it for few minutes and see if it reset it’s self, before I go to any great expense.
Also I had a washer that quit working on one cycle but would work on the others, could try that as well. Hope this helps!

this is not from me but i found it and am passing on..
Hi


Thanks for using FixYa. Error code 4h means 4 hour delay start which means that the dishwasher is in delay start mode and has been set to 4 hours. You can either wait for 4 hrs or to start it immediately press the cancel button to cancel the delay start option. After this program the cycle and options and press Start again as the dishwasher will not start the wash until it reaches the delayed hour i.e. till 4hrs. If after 4 hrs still the light blinks and it wont start then you'll have to replace the control panel. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

Alarm conditions during operation of the dryer

The LEDs begin to flash if one of the following malfunctions occurs:

• NTC open (the LEDs flash in sequence from right to left)
• NTC short-circuited (the LEDs flash in sequence from right to left)
• If the START button is pressed for more than 20 seconds while a cycle is in operation all the LEDs flash.

If the microprocessor identifies one of the conditions listed above, operation of the dryer is interrupted; the LEDs continue to flash in order to warn the user of the malfunction.
If the error is eliminated, the dryer returns to normal operation when the programme selector knob is turned to RESET and the drying cycle is re-selected.

You should only use distiller water in the steamer. Never ever use tap water! This is what caused lime and scale build up.
Since it's to late, you have nothing to loose by trying this to descale the unit:

Put up to one cup of white vinegar into the reservoir. Fill 3/4 of the way with water. Turn unit on and let it heat up, but DO NOT RUN STEAM THROUGH THE LINE. Once heated up, turn unit off and let it set for hours. Drain and rinse well. Then run a water only batch through the steam cycle. There are companies that sell special de scaling solutions. But hopefully, the vinegar will work.

Place the unit in diagnostic to do this make sure machine is off turn control knob to the left at least 3 times to clear now turn knob 3 clicks to the right 1 left 1 right all lights should light up do this within 6 seconds if you don't get lights repeat process I do this everyday so be patience once all lights are lit turn to the right until done light is lit press start button you will now see lights flash in varying sequence the way to read this the lit fill/sense light is the f code, wash light =8, rinse =4, spin=2, done=l when fill/sense light is not lit this is the second halve of the code example F7E1 you would have fill/sense lit, rinse=4, spin=2,done=1 F7 code, non lit fill/sense done=1 okay you may have more than 1 code it will continue to read the same code until you turn the knob once to the right the control will hold up to 4 codes at a time once you find the codes we'll go from there

Most likely the control panel is defective. Go to the repairclinic.com for further diagnostic help and parts.

Hi-Temp Wash, Hi-Temp Rinse, or Sanitize options.
Some models have options that may require a water heating delay, such as Hi-Temp Wash, Hi-Temp Rinse, or Sanitize. Additional time may be required to heat the water to the proper temperature. The dishwasher will continue to circulate water during this heating delay but the timer will not advance until the proper temperature is reached

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.

TO OPERATE:

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.

**TO CANCEL A CYCLE:
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.**

DELAY START:
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.

TOP RACK ONLY:
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.

REFILL RINSE AGENT LED:
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.

“F” CODE:
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.

The same thing happened to our Mr. Coffee this week! I followed the instructions about running vinegar through, then rinsing several times with water. However, the light would not stop blinking. We did by-pass the light by setting the timer for delayed brewing and it worked. However, that blinking light came on again. Then, my husband tired the vinegar wash again but instead of doing it one time, he ran the same vinegar through 6 times until the light went out! Then he proceeded with the water rinse. Our Mr. Coffee is working again!

try hitting 'heat dry' 'normal' 'heat dry' 'normal' should light up all the lights then go into test cycle washes, Once it finishes test, about 10 mins all should be good.
