Roborock S55 | Error 13 | Mainboard fuse exchange | check description

This method works for many Roborock models.
Please do follwing steps:
1. Clean power pads (vacuum & charger). Test the system. If does not work, go to step 2.
2. Check charger voltage. It should be ~4,2V without load and ~19,6V with load. If the voltage is correct, skip to step 3.
3. It looks like your fuse is damaged. Please replace it according to this video.
Fuse model: RUEF300 PTC 3A 30V
New fuse costs ~0,2 USD.

Hi Everybody! I have Roborock S5, and the charging is not working, the vacuum cleaner always come off form the charger. How can i find out if the charger is the problem, or the battery or the vacuum cleaner mainboard? Thx in advance!

[@YZFMANIAC08]

Nice job, thanks for explanation 👍🏻✌🏻

[@davidfiori3861]

In my S50, fixed the charging error by changing the main capacitor in the charger. 10 minute job.

This fixed the Error 13 on my Roborock E25, thanks!

[@TechDayEveryDay]

You are welcome;)

I went into this with no soldering experience. When I took the bad fuse off, there were two reddish rectangles underneath. Are those solder pads? I removed those too and there was a metallic material underneath the red rectangles. Was the new fuse supposed to be soldered to those red pads?

[@tomaspalencia877]

Yessss it works. Thanks for sharing my roborock is back!

[@TechDayEveryDay]

You are welcome

[@q3bing]

May I ask where did you get the replacement fuse in the US? Thanks!

Measured the resistor and it shows 0.15-0.4 values. Jumped it with a wire just to be sure....stil have the same error...any help? Battery ang charging station measures where ok. Also switched the battery Frome and with a friend's robot and his work fine with both of them, mine gets the error 13 with both ones

[@pawelkdi]

it works thanks !!!

Hi, temp of the air flow?

[@ryana42]

Where do you get a fuzz like this? How Do I know if it applies to the s7?

[@marcocornell7310]

Moin, ich habe das selbe Problem wo kann ich so eine Sicherung bekommen? Gibts irgendwo auch einen Schaltplan?!

[@eshtrum]

What is the liquid that you put on the bad fuse to take it out?

[@iam5085]

Flux?

[@Akerfeldtfan]

Unfortunately that didn't fix it. will keep looking!

[@schr3ck3]

What are you using there to get of the old fuse?

[@TechDayEveryDay]

I'm using hot air.

[@schr3ck3]

@@TechDayEveryDay with what device? And what is the liquid? And isn't there some danger because of the hot air and the parts close to the fuse which should not get broken?

I changed the whole motherboard and that didn't solve my problem, so i changed the charging base and then yes that was definitely solved

[@Henrik229]

Hi I also have a error 13 problem with my robot. But mine charges. Once the robot is charged and i try to start it it just turns off. Once it restarts it starts to charge again. I tried a known good battery but the problem still prevailed. I also jumped the fuse on the Mainboard but it did not held. What could I try now?

[@samashraf4587]

[@Devilot80]

I have that!!!!
