The electronic display shows F-01 - Hotpoint Aquarius WD640 Front Load Washer/Dryer

an E4-01 is a fuser warm up error...this is usually caused by a bad thermistor but can also be caused by a bad fuser lamp or thermostat

the problem is with a electronic board, so nothing can be done by the used, the specific board need to be replaced.

You can get the Nokia X2-01 Restriction code from the site Onlinegsmunlock.com/unlock-your-phone/rs7wp2/ and Unlock it easily...

NOT ASSIGNED means no cashier is signed on. Find the cashier number button, probably labeled CASH #. In REG mode, press CL to clear the error, then 1, then CASH #, and Cashier 1 will be assigned. The display will show -01- Go straight from here into your sale.
Some registers are set up to not show the cashier number on the display or receipt. If 1 CASH # doesn't work, try CASH #, 1, CASH #.
Most users don't track sales by cashiers, so they forget they even have the capability, and they forget how to use that CASH # key. If you press the CASH # button without entering a number, it will sign out the active cashier, and you'll get this NOT ASSIGNED error.

what is it that you are using.

there are 1000 of things one can add to DT.

Helloduranjp,
Welcome to fixya.

You said, Your Bosch dish washer won't work. A number 1 is displayed on the electronic panel.

If it is displaying"01" then that means the extra dry setting is being applied!
Did you try to use the extra Dry setting?
Did the dishwasher work before this or is it brand new?
What is the model number and year?
Let me know ! I'm waiting for your response

Below is and example of the usage of 01 or 00 in a Bosch Dishwasher!

There is a software Problem on the electronic in the back of the coffee maschine.
Changing that electronic to the new version will sort that Problem.

Depending on the software of the Norstar it is connected to, you would log in to the key system by using Feature **23646 and then follow it up with the administration password.

If this is a pre 1.0 system, i.e DR5.1 do the following. If not, go to the bottom and click on the link and find the manual for the system your phone is connected to. Generally the system coordinator guide will have what you are looking for.

example, February would be entered as “2”.
- The time may be entered in either 12 or 24-hour format. If the
display is in English, and the hour entered is less than
thirteen, the display prompts you to specify “am” or “pm”.

Press [Show] This will open the time change function. Simple rule. If you want to modify a value, press [CHANGE] and you'll get a cursor. Once you're done with that entry, press [NEXT] to go to the Minutes, press [CHANGE] etc...

Display shows [YY MM DD W HH MM]. - Dial new information as follows: YY = Last two digits of the year MM = Month (01-12) DD = Day of the month (01-31) W = Day of the week (1-7; week begins on Monday (1) and ends on Sunday (7)) HH = Hour (use 24 hour clock) MM = Minutes (00-59) - Dial # to set current date and time.
