I am having problems getting dishwasher to restart after I interrupted a cycle. I have done the cancel cycle pressing Normal and Delicate together. The dishwasher emptied then showed a PF signal. Now is it showing a LE signal and all Front display lights are flashing.

If turning off the power for an extended period of time did not fix the issue, it's possible that the problem is with the dishwasher's control board or sensor. Here are a few troubleshooting steps you can try:

1. Check the water supply: Make sure that the dishwasher is getting a sufficient supply of water. If the water supply is interrupted or low, it can cause the delicate light to flash.
2. Check the filter: Make sure that the dishwasher's filter is clean and not clogged. A clogged filter can also cause the delicate light to flash.
3. Check the float switch: The float switch is a safety device that detects when the dishwasher is overfilled with water. If the switch is stuck in the up position, it can cause the delicate light to flash. You can try to locate the float switch and gently move it up and down to see if it helps.
4. Check the door latch: If the dishwasher's door latch is not properly engaged, it can cause the delicate light to flash. Make sure the door is closed and latched securely.

If none of these steps resolve the issue, it's possible that there may be an issue with the dishwasher's control board or sensor. In this case, it may be best to contact a qualified technician to diagnose and repair the problem.

Check float valve actuator, might be indicating empty when water left behind. Think you can hear switch actuate as you move it.
So no clog or twist in drain hose? Manual indicates any standing water drains in first 45 secs. Makes me wonder if that is now normal. Was it always or just started to leave water....
Make sure you clean filter located in bottom

have a service technician in as it appears to be a problem in the program board
could be moisture across the circuit board

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.



Dado

With the dishwasher door closed and the unit in standby mode or with no cycle selected and all lights off, press - heated-dry, normal, heated-dry, normal buttons in that sequence. Then press cancel..... wait until 2 minute cycle is done. Open and close the door and make sure it is closed. Then run another cycle.

The Start/Resume light is flashing

This flashing light indicates that your cycle or start-up was interrupted.
Possible causes: The door opened during the cycle, or the power was interrupted.
To resume operation: Make sure the door is closed, and press Start/Resume.

The Clean light is flashing

You should call for service if the Clean light is flashing and the machine is inoperable. It is normal if the Clean light stays on after the cycle is complete. The Clean light is an indication that the dishwasher has been run and that the dishes inside it are clean. Once the door is opened after the cycle is complete, the light will shut off.

The lights are rapidly flashing

Any key that gets stuck will rapidly flash. Press the key a few times in order to release it or press Cancel.

The Rinse Only light is rapidly flashing

If multiple keys are stuck, the Rinse Only light will flash. Press each key, one at a time, to release the stuck keys, or press cancel.

I suspect you have your dishwasher set for a 1 hour delay start. Press cancel and restart in a regular/normal cycle and see if it programs.

I think it is difficult. If programmed that way, you have to wait till the cycle is complete. Even if you switch off/on, it will resume from the old setting only.
Or contact service provider or refer user guide. You may have to hold two switches pressed together to cancel.

The console (control panel) is defective. The buttons may be getting stuck and/or are corroded.
