My Tresnati desk from Costco is not working and the customer support has been pretty terrible so far, they want to create a ticket with ALL my contact details just to help...it feels scammy. Does anyone have a fix for the "E3" error or the TOP error? My desk is currently stuck in standing position and I can't fix it.

So a few years ago, this desk was sold at Costco, and since then it seems several people have had issues with it.

In the first case, the circuit board falls out of sync with the stepper motor, which is easily solved by moving the desk all the way up with the 3.5mm jack disconnected.

However, in my case, the circuit board was stuck at "BOT", preventing the desk from going down and moving the desk up any significant amount resulted in a "E3" error code, indicating no signal from the motor.

CS will automatically assume that this means the motor is bad and will offer you a new motor under warranty. This will work if the motor connector is loose or the motor is stuck. However, in my case it was the desk-side connector that was loose, as evidenced by bending the connector with my hands fixing the issue.

Repairing this requires cutting off the rubber housing with a box cutter, removing the pins with one of these and then crimping on new Minifit Jr pins with a Molex crimper. I also recommend some heatshrink and Sugru to seal up your work. If you do custom cabling for desktop computers you should already have the necessary tools, otherwise you will most likely have to buy.

I purchased the Tresanti motorized sit/stand desk from Costco 4 months ago, and I think I found out why it was such a great deal compared to other desks.

This morning, it wouldn't move up from lowest position. It says "top" after about a half second movement, maybe 1/4". There is a new sound on the left side that sounds like a loose clunking. I would guess there is a mechanical sensor that is supposed to stop the desk at the top of movement, and perhaps that is loose and triggering too soon.

Anyway, that's just a guess, and I'll probably take it apart to try and fix. Since the desk is no longer in stock, Costco will take a return disassembled via UPS and assembled if I take it to the store. Other sit/stand desks are several hundred more than this, so trying to fix seems worthwhile.

Has anyone experienced this?

Just got my new tresanti desk from Costco and have had nothing but problems ever since turning it on. Constantly getting E3 errors and now it’s all the way up but it says it’s “bot” so I can’t go down. Tried reset but that doesn’t do anything. Anyone have this problem? Gives me E4 and E3 which both say are about power. Can’t figure it out. Decided to go to bed. Hoping for better luck tomorrow.

I need help troubleshooting my brand new tresanti desk I got from Costco (haven't even worked a day yet with it).

It appears that the measurement is off on the desk meaning when I press down it says "bot" but the desk is in a standing position (probably was 40ish inches when I put it in this place). My preferred sitting height is where it usually would bottom out, but now I can't get it to go down.

I've read the other troubleshooting posts and when I disconnect the headphone-like jack it disconnects the power to the controls so I can't move the desk. If I move the desk up as high as it will go it eventually sends an E2 error and never reached 'top."

Does anyone have experience with this issue? The desk is functioning fine (no unusual sounds, feels smooth), it just has the height counter wrong.

TLDR; my new desk says its at 'bot' when it really is a standing position and I need help resetting the height orientation. TIA
