KP41S3U LED FLASHES 12 TIMES

What is the Brand and model of your washer ?

Is it Indent ?
Many basic UK Indesit washing machines fitted with a rotary dial indicate error codes by clicking the dial continuously round and flashing the door lock light a set number of times.
If the door light (LED) flashes 7 times it means, "Heater relay stuck - check connections on heater and module (PCB)".
In my experience, this fault code usually required a replacement PCB and EEProm. A connection fault on the heater usually results in the entire washing machine going dead. Nothing will work, but the LEDs light up. This symptom can also be caused by an open circuit motor or other faults.

It's always possible for a connection fault to cause error codes but the heater relay is embedded in the PCB and if it develops a fault the whole board needs replacing. I don't recommend replacing the PCB as a DIY repair. It is an expensive part and it will not be guaranteed unless fitted by an engineer. New PCBs do not come with the micro-chip EEPROM which would also need fitting. Replacing the PCB and EEPROM yourself is risky. If the fault is not cured you cannot send the parts back.
If you have an engineer to replace the PCB and EEPROM I would imagine the cost is likely to easily be over £100. If your washing machine has a 5 year parts guarantee Indesit would supply the PCB free of charge but only if their own engineer fits it at a cost of about £90.
If you are really keen to fix this yourself and want to try another PCB there is a company that might be able to help and are happy to deal with the public called Quality Electronic Repairs (see link below)

Most likely your dishwasher finds fault.

Appliances without a display will show the alarms by a number of flashes of the LED "end of cycle".

For example: one flash = i10, two flashes = i20
..........and so on

So, count how many times LED "end of cycle" flashes and you will know the error code.

There is a led light in the upper right corner of the front. The controls are on the large round button in the center. To turn in on, press in the center of the button; the device will turn on and playback will begin. To turn it off, press AND HOLD the center of the button until the LED light flashes several times and then turns off.

To play, press the center of the button and the LED should come on and stay solid. To pause, press the center and the LED will blink once a second Press again and playback will resume.

Think of the big button as a clock face. Press at 12 for volume UP. Press at 3 for next track; HOLD for fast forward. Press at 6 for volume DOWN. Press at 9 for previous track; HOLD for rewind.

For shuffle, press at 12 and 6 together and hold for 2 full seconds. The LED will flash 4 times to show you are in shuffle mode. To go back to normal playback, press at 12 and 6 together for 2 full seconds and the LED will flash 2 times to show you are back to normal mode.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power led, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

Hi Daniel,

Please check if you can access the "error code operational check" to narrow down where the fault came from.
How to enter to error code operational check.
Note : The TV must be in shutdown and not have been switched off. When the TV is switched off, the error code automatically resets to 12 (no error).
Press the buttons on the front panel "Input/Device" and "Menu" at the same time and hold it for 5 sec, activate the error code mode. The LED light will flashes denoting a two digit error code.
Example : if the error code is 22, the led will flash two times pause and then flash two times and will repeat the error code for five times.

If you can't access the error code operational check , please let me know the exact pattern of the flashes of the led light and its color. Check if it will continually flashes green to give you the caused of the symptoms and best solution.

Good luck and take care.

Error Codes
A green LED indicates system faults
Steady On: System OK
Steady OFF: Board control fault or no power applied
1 Flash: Ignition failure (control in one-hour lockout)
2 Flashes: Pressure switch fault, fails open (switch is
stuck open)
3 Flashes: Limit switch open (main or auxiliary)
4 Flashes: Pressure switch fault, fails closed (switch is
stuck closed)
A yellow LED indicates flame status
Steady on: Normal flame is sensed
Flashes: As flame weakens, frequency of LED flashes
increases
hope this is helpful.

The L.E.D. located on the tiller
dashboard will indicate with flash codes what problem is occurring.
L.E.D. Flashes 1 time and pauses, 1 time and pauses…. Batteries are low,
scooter will still operate.
L.E.D. Flashes 2 times and pauses, 2 times and pauses…. Batteries are very
low, scooter will not operate.
L.E.D. Flashes 3 times and pauses, 3 times and pauses….Over voltage to
controller.
L.E.D. Flashes 5 times and pauses, 5 times and pauses….Brake is in the
freewheel position or connection to brake is open.
L.E.D. Flashes 6 times and pauses, 6 times and pauses….Paddle or speed
potentiometer problem.
L.E.D. Flashes 7 times and pauses, 7 times and pauses….Paddle or speed
potentiometer problem.
L.E.D. Flashes 8 times and pauses, 8 times and pauses….Motor
disconnected or faulty.
L.E.D. Flashes 9 times and pauses, 9 times and pause….Controller fault.

I hope this helps they are pretty standard codes I got this from Golden Tech Web Site

This problems very common on Sharp Tv.Do ur tv LED power light turn on solid first.Few mins,than LED,OPC flahes.Power LED,OPC flashes,push power button again,do this at leat 5 or 6 times somtimes the backlight will come back on and work.The power LED,OPC light flashes,turn off/on more than 5 or 6 times don't work.Ur Tuner signal board is dead,must replaced.
