Citroen relay common faults

These locks don't work like traditional mechanical locks. It's just spinning as the lock and key are designed to do it if a wrong key is used. Original keys can become too worn to engage the mechanism inside it making it spin the same way. Try these basics.
Do you have a spare key you could try? Is there a key slot in the passenger side door you could try? Could you get to the driver's seat through the side or rear doors? Have you tried spraying a fine oil into the lock to lubricate it.
*NOTE* Do NOT use WD40 as it is not an oil. I would suggest something like GT85 or 3in1 spray.

There is something called a BSI or BCM in those cars that tends to fail. The BSI is a computer that controls all those functions. Since I am not sure where you are located, use a search engine and put in the year, make and model and the term BSI or BCM and look at the results.

Sound like the lock actuator is at fault if it only unlocks with key. Also check wiring in door hinge area for wire breakages. You will probably find its dealer only for the part.

Put your ear to the door and listen to where the grinding/buzzing noise is coming from when you lock the door, sometimes it maybe more than one door! The door it's coming from need a door actuator, common fault with the k12 micra's, which i'm guessing this is a k12 model!

Can you give a check to the micro switch that is connected to your boot lock?
If the catch gets stuck, open your drivers door, leave it open,reach across & press down the lock on the passenger front side. The locks will lock/ unlock themselves, because they sense a door is open. Repeat this action until you hear the boot unlock. Also, keep your battery well-charged.
Let us know if this helps!!

Hello 2cats - First, is the drain pump making a humming noise? If so, the unit could possibly have a restriction in the drain line. Try setting the cycle to spin only and verify if water pumps out. Other possibilities could be a faulty door lock, timer, pump, or control board not communicating correctly. In this case I would contact a professional to move forward accurately to properly diagnose and repair the washer.

I HAVE THE EXACT SAME PROBLEM! DID YOU FIX IT?

It may be as simple as a failed door switch. It would appear one of the switches has failed "open" keeping the light on and not allowing the locks to lock. Check each switch to see if you can find an issue with one, perhaps the plastic plunger broke and when the door closes it will not open the switch.

Please let me know if this assisted or if you need additional help.

Thank you,
Tom

door switch is not working.

One of your door lock inside switches are bad.Find the one that doesn't feel right when you push it in either lock or unlock.The internal spring is broke causing the lock relay to keep try to lock or unlock until it gets hot & protects.
