- A solid green LED in a Husqvarna Automower charging station means everything is good to go and you have no problems with your charging station or boundary wire, right? Not always! In this video you will see a situation where the mower gives a no loop error, the charging station has a solid green LED, the boundary wire has the absolute minimal resistance in it possible, but the mower will not pair with the charging station. We also show you a scenario where the mower is paired with the charging station but gives a no loop error while having a flashing blue light but the boundary wire is in perfect condition. So how do we diagnose these issues where we are being deceived by the charging station LED? The answer is we test the voltage being passed though the charging station by the charging station circuit board. In both of the errors mentioned above it was proven that the charging station board was the cause of our no loop issues. One time because it was sending no voltage to the boundary wire despite having a solid green LED and the other time it was not sending enough voltage to the boundary wire and caused the flashing blue LED. We also show you how you can check your guide wire system by measuring the amount of voltage the charging station board is sending to those terminals as well.

Thank you for watching!
u are my saviour! my 310 stopped and gave me a no loop signal, then it didnt wanna charge, opened the charging station and took out the card to check, and yep there was a burned bit of card, so i swaped it out for one i found on the garbage free of charge, installed it and it took charge, but i had the no loop signal. after ive been pulling my last few hair on my head i found this video and i ran as fast i could down the stairs and into the mower, straight into security and new loop and TADA IT WORKS!! im so happy! i hope you have a good life !!!!
Glad you were able to get it working!
The tip about having the mower out of the charging base when starting the new loop signal creation was helpful. It actually created it but the mower pauses on follow out and now won't create a new loop signal.
Looks like I'll be needing my multi-meter tomorrow!
My god man. Thatk you! A million times over thank you! I am like 7 hours into trying to figure this out. I got a board and put it in. Now it works.
Awesome! Glade we could help!
I replaced my board last year but the board was more obviously the problem, no/low voltages at the boundary wire terminals. Voltages are high at 32V now even though the transformer feed is 28V but have the flashing blue light.
I initially had flashing red and diy repaired a break in the home wire antennae in the base station floor but was greeted with the flashing blue next. I got a new board but it made no difference… at a loss now
Here's a troubleshooting guide that will help you diagnose the issue: www.roboticmowerservices.com/post/troubleshooting-a-no-loop-signal-error-on-a-husqvarna-automower
Thank you so much for this video and all your videos. With it I was able to identify my no loop was down to the charging station board which I was then able to quickly swap out. Keep up the good work

Awesome! Glad we could help ya out!
Love your video's. Didn't found a other chanel that's nearly as good as yours. Thanks and greetings from Frankfurt ✌️
Hi, great touturial…i got one of the older 305, with the 21v power supply.. the station gets 21,6 volts steady, and with boundrywire disconected, the board hummes, make sounds… i measure a fluktuatin voltage to the boundrywires(disconected) going from 18 to 22volts, on guide output 3 to 4,5 volts..
Mover charges and the light on station works well, green, blinking and blue…. Do you think it is the board.?
Thanks for great info. I changed my pcb card on my 435x base. Now it goes out to mow and goes away out past boundary wire hits the fence and stops and just sits there. No loop signal. I have a green light. I have 33v on loop and 14 on guide. 4.5 ohms on complete circuit and 3.9 on guide. I have relearned the loop with no problems. Don’t know what its problem is.
Great video! My 450xh just started goofing around. Would go forward a few inches and stops, turns a bit, move forward a few inches and stops,... Solid green light in the station. I get 27.7 v where the mower recharges, 4.6 v on all guide wire tabs, but only 25.5 v on the loop tabs. I guess its either the board or the harness to the terminals.
I'm also getting 25.5V on the boundary. Did you find a reason why you were losing 2V and were you able to resolve your issue? Thanks
This has been brilliant - very clear and well illustrated and I've followed every stage, thank you. However, I've got to the end of your testing programme with solid green light, 28 volts in & 28 volts out on the boundary wire and the charging pads and perfect continuity on the boundary wire but it's still showing zero on all the signals - loop and charging station and won't pair. Any ideas, please?
Probably mower related at that point. Possibly a front loop sensor or main board issue
@@RoboticMowerServices thanks for your help.
Great explanations, very clear and to the point 👌👍
Thank you
Hi tested my 315 year 2015 and i have 30 v between the 2 boundry wires so thats ok but when i messure the guide signal from the charger i have 13v ,is that correct?
Same here on a 415x. Wondering if it is a different spec for these models or are we having a problem with the board. I started checking mine because of odd behavior when using the guide wire...
Same on my 330x 32 v on my boundary wire and 13 v on my guide wire. The search goes on.
They voltage on the loop terminals is 11v ac on my station that is working correctly, is it different here in Europe I wonder ?
I got a Mow Ro robot lawnmower docking station light is suppose to be green. It’s a blinking red light now! I live in Houston and as you might know the Heat has been brutal! Any suggestions would be much appreciated.
I have an automower 330x and checked all the output values and everything is correct. I have the problem the automower does not use the guide wire. On the automower i can see it does not have connection with G1. However it does give values for G1 for the lus sensors. Any ideas what could be the problem?
Hello. What is the lowest voltage output for the loop to work properly? My gives 25V out.
25 is about as low as you can go.
I have very strange voltages at my charging station (28 V):
between AL and AR: 32 Volt
between AL and G: 4 Volt
between AR and G: 14 Volt
How is that even possible with a 28 V transformer? And why is the current between AL and G not the same as between AR and G? Any ideas anyone? Thanks for your help!
Same here on a 415x.
Same here on 420 and have flashing blue. Did do a botch repair on my base station antennae wire that tells the mower it’s home and was immediately greeted with the flashing blue after stopping it from flashing red. Changed board and no good.
Hello Could you help me I have a 550H that I can not connect via Bluetooth, it tells me that it is disconnected, then no longer turned on or being in the station, then change the board and battery and I can not make it work that could do according to your experience that you share with us all.
Got a blinking green light and no voltage on the charging points. Any idea what it could be?
U sir fixed my problem. Installed new loop cable, solid green and no signal. But after I enter security and added new loop it now works flawlessly 👌🤌👍. Thank you 😀
Good to hear
thank you very much
The first part worked!!
Awesome!
So I have changed the power supply and the charging station board. I am getting the fast color changing light red. Also there is no volts on the charging outputs of the station either. Could it be that I got a bad board that I replaced?
What is the voltage coming into the board? And is the voltage coming into the board consistent? Meaning it is staying at a steady number and not jumping from 28 volts to 31 volts or something like that.
@@RoboticMowerServices I will check.
@@RoboticMowerServices When I put a paperclip in each hole of the actual plug from the power supply I got from about 2 - 9 volts and it just bounced back and forth.
Got flashing blue LED. Boundary wire resistance is good - 1 Ohm and AR/AL terminals are reading 28V when disconnected from boundary wire. The Guide wire terminals are reading 4 8 and 12V though. Don't know what to try next.
Me too
Have you solved since this was 4 months ago? 😬
@@alanmannion8670 yes. It was the circuit board in the basestation. Replaced and works perfect now.
Thanks very much for getting back to me!
I replaced mine last year but the board was more obviously the problem, no/low voltages at the boundary wire terminals. Voltages are good at 28v now but have the flashing blue light.
I was initially repairing a break in the home wire antennae in the base station floor but it started to rain and I had it still plugged in. So the water may have fried the board again. Thanks again. I’ll have a think and prob replace the board too. 👍

really helpful
easy and sure thank you😊
Chrgeing station only charges when I lift off the boundary cable
Bad kitty, your ruining my shot1 (18:41)
My 435x is pending between 15-29 volt and i have changed transformer and the the board in the station.. Heeelp!
