Alma Fault Codes

Some Alma fault codes are easy to fix, others require specialist assistance.

If your Alma laser device displays a fault code, it usually indicates that one or more components require attention. These system faults can range from handpiece recognition issues to cooling system warnings.

We specialise in diagnosing and repairing Alma laser faults efficiently, helping clinics minimise downtime and get devices back to full functionality. Below is a breakdown of common Alma fault codes, what they mean, and how each issue can be fixed.

Alma Fault Codes

Fault Code	System Fault
iButton INC Failed / Head Error iButton Failed	The device is unable to read the iButton chip in the handpiece. This can indicate a faulty iButton, poor connection, or corrupted chip. Replace the iButton or reconnect securely; in some cases, the handpiece may require refurbishment. If the issue continues, contact a GoLaser professional and we’ll be happy to help.
Handpiece RES Error	This error points to incorrect resistance readings from the handpiece, often because of damaged internal components or poor contact. Inspect and repair or replace the handpiece circuit board or contacts. If the issue persists, contact a member of our team.
RS232 CS Error / RS232 WD Error	These indicate communication difficulties between system components via the RS232 serial connection. Check and reinstall internal cables; replace communication boards if needed. If the issue continues, contact GoLaser for support.
Connect Interlock	The interlock safety system is not engaged. This may be caused by an open circuit or a disconnected footswitch/key. Ensure the interlock loop is properly connected and functioning. If necessary, replace malfunctioning interlock parts. If the problem continues, contact one of our friendly team members.
Flash Init Error	There is a Flash Data Error. On the Technician screen chose the "Fix Flash" and wait a few seconds, and press the "save" button. Then, shut the system down, wait a few seconds again, and turn the system on. If the problem continues, contact one of our friendly team members at GoLaser.
FlowSw Error / FlowSw OFF Error	Suggests a malfunctioning flow switch or insufficient water flow. Turn system off, wait one minute and restart. Make sure the coolant pump is operating, examine and clean the water flow sensor, and look for obstructions in the tubing. If the flow switch is defective, replace it. If the problem persists, contact one of our friendly team members.
Level Switch Error	A sensor or float switch problem is preventing the device from detecting the anticipated water level. Check the water tank level, clean the level sensor, and inspect the switch for faults. If your problem continues, contact the GoLaser support team.
LCD Does Not Match MCU	Android Apk version does not match. Update the software to make sure that it is a matching pair. If your problem continues, reach out to the GoLaser support team.
LevelSw Error	Turn the system off, wait 1 minute and restart it. Check the water level and then check the flow switch. If your problem is still occuring, contact the GoLaser support team.
Simmer Error	The laser's simmer circuit is not firing correctly, possibly due to an issue with the flashlamp or driver board. Inspect and replace the flashlamp or driver components if needed. Contact GoLaser for any support needed.
Pulse Data Out of Range	The laser parameter is too long. Shut it down and reach out to GoLaser for a service.
Head Error VB1=0 VB2=0	Voltage readings on both VB1 and VB2 are zero, indicating a serious head or driver issue. Contact GoLaser to test the power supply and head connections; repair or replace the affected driver circuitry.
Driver Error Laser Off / Driver Error Over Curr	These error codes point to an issue with the diodes within the laser handpiece, typically caused by diode degradation over time due to extended use. The handpiece may require refurbishment, including replacement of the internal diodes. Contact the GoLaser support team for handpiece refurbishment and repair.
Driver Error Overtemp	The laser driver has exceeded safe operating temperatures. Check cooling fans, thermal sensors, and airflow within the unit. Any failed cooling components should be replaced. Contact GoLaser if your problem persists.
Driver Current Error	During lasing in OFFTIME, A/D value > OffDrv*2 or value < OffDrv < 2. Connect a new handpiece, then check the MEG 150. Contact GoLaser if your problem continues.
Driver Current Off Error	At START, STBY, and READY the A/D value > 100. Connect a new handpiece, then check the MEG 150. Contact our friendly team if your problem continues.
Save Data Error / Date Time Error	These issues are caused by corrupted internal clock settings or a failure to save system data. Reset date/time in system settings; inspect internal memory for faults. Replace the motherboard if necessary. Contact GoLaser for any support if your problem continues.
Unrecognized Applicator	The connected applicator does not belong to this system. Connect a new handpiece. Reach out to GoLaser for any support if the problem continues.
ThermalSw Error	The coolant temperature level is too high. Check water level. Then, wait for 15 minutes and restart the system, and if the system starts, then the problem is water temperature too high. So, check the room temperature and clean dust from the heat exchanger. Contact GoLaser for any support if the problem continues.
Freq Error	There is a laser signal frequency error. Restart the system and check again for any error, if the error persists, then install the last software on the interface controller and LCD and check again for any error. Contact GoLaser for any support if the problem continues.
No Pic Detected	No answer from pic tester. Check with another HP if you get the same error, if not, you need to go to the technical screen, disable PIC, restart the system, and see if the new error message appears. Contact GoLaser for the necessary support.
Pulse Power Out of Range	Check if the RED switch on the Interface controller is on PROG. If it's not, switch it and turn on the System. Contact GoLaser for any support needed.
No Pic Signal	Shut down and reach out to GoLaser for assistance.
Pulse Time Out of Range	Check if any wire from the 15 pin D (type of connector on the PIC controller) is loose, if it is, connect it back by Soldering. Reach out to GoLaser for any support needed.
PIC Version Error	PIC Software version error. Check match between the PIC versions to the controller, if a match is not found then reinstall the right match. Contact GoLaser for any support needed.
Machine Init Error	Machine failed to initiate Limit/Unlimit. Shut down and reach out to GoLaser for the necessary support.

We contacted GoLaser with an urgent request for a Soprano Titanium after being let down by our previous supplier. Konrad delivered a device within the day! Outstanding service! As a business owner committed to offering the best service possible to our clients, it's reassuring to work with a company that shares the same vision. It's great working with you again, Jamel. Thank you.

We contacted GoLaser after the company we had used for many years to service our laser let us down and almost doubled their prices. Mariusz came on a day that was good for us and we couldn’t be happier with his expertise and professionalism. He was polite and incredibly knowledgeable, taking the time to explain any issues thoroughly and being fully transparent with his work and findings. He gave us complete confidence in the maintenance of our equipment. We highly recommend Go Laser and Mariusz for anyone looking for reliable and expert laser servicing or repairs! We will definitely use again.

I recently had the opportunity to use Go Laser servicing, and I was thoroughly impressed with the experience. From the moment I reached out, the communication was clear and professional. Konrad took the time to thoroughly assess the laser equipment, explaining the issues and offering a detailed breakdown of the necessary repairs and maintenance.

What stood out was his expertise and attention to detail. He was able to quickly diagnose the problem and resolve it efficiently. The service was prompt, and the equipment was returned in perfect working condition. Konrad also offered helpful advice on how to maintain the laser for optimal performance in the future.

Overall, I highly recommend Konrad for anyone in need of laser servicing. His knowledge, professionalism, and customer-first approach make him a standout in the industry. I will definitely return for any future laser maintenance needs.

I’m so happy I found this company online. After ringing around and getting quoted ridiculous prices and other engineers not being very helpful I felt deflated, but then I spoke to Konrad and he put my mind at ease.
I would highly recommend GoLaser. Konrad is very efficient and knowledgeable. You honestly can’t go wrong, the service is 10/10.

Fantastic service. Excellent communication throughout. Had our handpiece refurbished which included a totally thorough service of our laser machine.
Konrad showed us everything he was doing, nothing at all was hidden. The door was open throughout... much different to past experiences from other companies when we weren't allowed in the room!
DEFINITELY recommend to anyone wanting an honest and thorough job.
Thank you so much GoLaser

Just had our first service after changing to GoLaser for our service and maintenance plan. Once again the professionalism was second to none. Fabulous job again. VERY HIGHLY RECOMMEND

Had my Soprano Titanium fixed by GoLaser, I was very impressed with the quick respond and adressing the issue straightway without messing about, not been taking the advantage of us needing an engineer urgently , been honest from the beginning which is really important for us as we're with no technical knowledge on part pricing.
On the day of repair Konrad came fully equipped and fixed the problem in a very professional and confident way.
Also thank you for answering all the questions patiently we had asked throughout the whole repair.
Definitely Will be using GoLaser for all our services.

Excellent service, including communications over the phone and arranging visit/s. Felt valued as a customer and it was clear that GoLaser were trying to find a solution that made sense for me rather than forcing me into their pre-set tariffs. Thank you.

We contacted GoLaser after our usual company we use had a long response time (5+ days) for an engineer to be sent out. Konrad arrived within a few hours and came to the rescue. He was able to assess the damage to our Alma handpiece on site. Took away to repair and had it ready in less than 24 hours meaning there was minimal disruption to our business. He is also coming back to service our device next week. Very impressed with the overall knowledge, experience and service provided by Konrad and we will be using GoLaser for all our future needs from now on. Thank you again Konrad!

Konrad was recommended by an industry colleague. I had a damaged and scratched IPL crystal head which he repaired over the Xmas holidays when everyone else was closed. He even returned in back to me in super quick time. Excellent communication ⭐️⭐️⭐️⭐️⭐️
Konrad goes the extra mile. He is a true gem and I highly recommend Konrad at GoLaser for all your laser repair and service needs. Top marks 10/10.

Konrad attended my clinic and carried out a really thorough Soprano Ice laser servicing. Previously I have used original companies and paid over 3.5k a year for a servicing package, in which they come and only hoover the machine, spend 10 min and charge you extortionate fees. I am extremely grateful for finding Konrad on Google as I will be using him for all my machines needs from now on. Also I will recommend you to all my colleagues and put your details in a group of clinic owners so they can all have the VIP service I experienced. Thanks Konrad. 🙏

The most trustworthy and professional, reliable service I have ever had.
I have my own business for nearly 10 years and I have dealt with a few engineers and I have had different experiences and not all of them good but GOLASER is truly amazing and I was really struggling when a laser machine company recommended them and I these guys saved me tons of money as I was told my machine is broken and it’s not repairable and it cost around 10k -12k, and could take a long time it was my main machine still quite new and I bought it around 3 years ago and it was a shock I was devastated.
I wasn’t insured for the parts.

He agreed to come and inspect the machine and he said there is a small chance he could fix it with a few hundred pounds and he ordered the part and managed to fix it,
None of the other engineers suspected the fault.
He also serviced my CANDELA ND YAD 1064, it’s even better that the first day I bought it.
Honestly I can write so much about how helpful GOLASER is but I can only tell you that I’m relieved that I know them because GOLASER don’t do it for money only they have passion, knowledge and a big heart to understand your situation too.
I would definitely recommend them , thank you GOLASER.

Very happy customer, I can’t thank the team at GoLaser enough for my new piece of equipment. It arrived and was put together with great care and ready to go. I’ve known Konrad for years and as former colleague, I trust his work and team implicitly !

I would highly recommend GoLaser especially Konrad. He came very quickly with the solution to my IPL system, so I could restart working with my clients after my IPL system needed a repair. Also he helped me to outsource the right handpiece for my system and adjusted the settings so I could get even better results with the system.
He is very knowledgeable and professional in his approach. And is able to find solution with all thingslaser like nobody else.
Highly recommended

My laser machine handle started leaking and I didn't know where it was coming from. I found GoLaser online. we got in touch on Monday and got a response same day. got the laser machine fixed pretty quickly
All I can say is that they are very professional, know what they are doing and also make things possible in repairing when others give up. very happy with them. I've kept them on the books to service my laser HR machine.

Very impressed and wished i found you guys sooner. I emailed and was able to get an engineer visit the next day. Konrad was really friendly and informative and knew his stuff. very happy with the service!

i have had my ellipse machine for many years and it was really overdue a service and repair. I had reached our to another company and had been chasing them for almost a year for the service. so i was so happy to be fitted in so promptly.

I'm looking forward to using my machine back at full capacity again!

I was introduced to Konrad through a mutual friend a few years ago whilst he was working elsewhere, so I was delighted to hear he had set up on his own.

I needed a service and repair on my Ellipse Ipl Machine so I got in touch with him a few days ago. He fitted me in very quickly (thank goodness) and everything from start to finish has been amazing.

His extensive knowledge within the Laser and Ipl field is mind blowing and that’s exactly what I got! He tweaked my machine so it’s now working better than ever along with taking one of my hand pieces away for a full refurb as he found a minor fault with it.

If I could give 10 stars ⭐️ I would! I would highly recommend Go Laser to anyone who has Laser or Ipl technology in their businesses and who wants a professional and experienced service from start to finish!

Thank you 🙏 thank you 🙏 thank you 🙏
