Electrolux PI915SSM: How to fix error code E23 and E21?

Wed, 20 May 2026 18:02:05 -0700

Hi,

I have problem with my pure i9.

I got e23 and e21 error codes and i bought new batteries to fix it. Its still showing same error codes, when i put it on charging station.

Sometimes it shows red battery icon, sometimes white, but error codes stays same.

I have cleaned charcing stations two metal pads and also pads beneath the vacuum. Pads are shiny clean and dont have any corrosion or dirt.

I have also cleaned the hole vacuum with bottled air, so vacuum is clean from dust and dirt.

Internet forums dont have anymore solutions to fix my vacuum. Some forums are telling that this pure i9-model usually get eletronic fault and it cant be fixed...

Can someone please save my vacuum from dumpster?

Narwal Freo Z10: Clean Water Tank Empty ... but it's NOT

Sat, 16 May 2026 20:23:25 -0700

We've had our Narwal Freo Z10 Ultra for about 6 months now. Love this thing! However, we seem to be having a recurring issue with the base station clean water tank. After filling the clean water tank and starting up, the narwal becomes angry from time to time and will say "fill clean water"... even though the tank is full and properly installed. My wife has found a temporary fix: using a baby medicine syringe to inject water into the base station clean water tank connection point. Doing this 3 or 4 times seems to clear up the issue... but a few days later same fault occurs. Anyone know of a root cause or complete fix?

Some things I have tried:

Cleaned both waste water and clean water tank thoroughly

Small pipe cleaner run through of all water lines to verify no obstructions

Thorough cleaning and maintenance of vacuum robot

This close to tearing the base station apart and doing a thorough cleaning.... when the wife isn't looking🫣

Samsung Jet Bot VR30T80313W: Battery won't charge.

Tue, 12 May 2026 14:49:13 -0700

So I just got my robot vacuum back after lending it to my brother.

Turned out it stopped working a while ago.

When I got it back I started to diagnose it.

The first thing I noticed was, when it's docked in the charginstation, it turns on and I can adopt it into the smart things app. The battery read 0% and no matter how long it charges it wouldn't go up.

So I started by disassembling the battery down to its individual cells. Turned out 5 out if 6 cells were completely dead (absolute 0 volts).

So I ordered some new cells and put the battery back together. The battery now shows 21,7 volts. But it still doesn't want to run outside the chargingstation.

When I use a multimeter on the battery, while it's connected to the chargingstation it shows about 25 volts on d+ to d- (the plugs from the vacuum to the PCB on the battery). And still 21,7 volts on b+ to b- (the spot welded tin to the battery). It has now charged for about 2 hours and it's still about 37% charged (so not getting charged).

I've tried to put the PCB under an thermal camera to see if anything gets hot, but it doesn't. Even with it plugged into the chargingstation, without the chargingstation or it disconnected from the robot. I've also tried to connect 21 volts 1 a with a powersupply connected both on d+ to d- and on b+ to b-, yet nothing gets hot.

Anyone have any idea on how I could fix this?

I'm pretty new to this stuff, but I do watch some youtubers like NorthridgeFix and TronicFix so I have some general idea.

Should I disconnect the cells again and maybe try injecting voltage over some of the chips on the PCB or check the resistance on some of the caps? If so i would love some guidence. I don't have a chip programmer yet, but I will order one sooner or later, if needed.

Roborock Qrevo S: roborock Qrevo S Robot Lidar error. Check that the turret turns freely

Sun, 26 Apr 2026 09:46:48 -0700

Does anyone have a guide on how to disassemble the Qrevo S?

Context:

My robot hasn't hit the year mark and yet he doth betray me with the Lidar error. I tried spinning the lidar with a cotton swab a few (15) times (it turns just fine), cleaning the area with a toothpick and vacuum, moving it, soft resetting it, hard resetting it and now I'm at a loss.

I followed this guide initially, but unfortunately it doesn't get me all the way to the turret motor in my model: https://www.reddit.com/r/Roborock/commen...

I have tried YouTube, google and am a hair's breadth away setting fire to my poor tool kit.

Any help or advice would be really appreciated.
