Introduction

My wife's Elvie Stride got some milk inside and suddenly stopped working. I was able to take it apart and disconnected the battery. After cleaning the milk off and letting everything dry, it charged properly and started working again.

This isn't a proper disassembly guide, but hopefully it gives you the courage to pop yours apart if it stops working!

  1. YX1mAfGN6FOs2SEs

    • Take off the rubber sleeve around the case.

    • The two halves of the clamshell are held together by about 9 plastic snaps - no screws or glue.

    • A handful of guitar picks and gentle prying on each side should be sufficient to pop it open.

  2. eWJOkMjqlBIKcSgD

    • Four T6 Torx screws hold a black piece of plastic into the front clamshell.

  3. UkEjnDTHVeZpdNli

    • The battery is held in place by a small bit of adhesive. A spudger and light force is sufficient to remove it.

  4. fB2VShIvmyoYhbLM

    uxyLFEwDMBYOk5H5

    • The PCB is held into the black plastic bracket with three T6 Torx screws. Remove these, and the device is almost completely disassembled!

    • The battery connector pops vertically out of the socket (not by sliding parallel to the PCB).

  5. yNaeOTL2eBH2mVeh

    • We can identify a few key components on the board:

    • Nordic Semi nRF52832 (Bluetooth chip)

    • Winbond 25Q32JV 32MB SPI Flash

    • TI BQ25601 battery charge controller

    • WCH WC340H USB-UART controller

Conclusion

To reassemble your device, follow these instructions in reverse order.

my battery keeps disconnecting inside the hub, not sure how to fix it but that could be a common issue with them.

Angela Darby -

I didn't have a guitar pick on hand but was able to use an old gift card to open this up. Any credit card would work here.

Randall Ary -

what battery is used? is it a common size one can buy easily, with a standard connector?

Gregory Fung -

It's a standard 18500 li-ion cell, nominally 2300mAh. I can't identify the connector but it looks similar to a Molex Pico-EZmate.

The connector is shrink-wrapped onto the battery, and could probably be removed and taped onto a new one.

Steven Bell -

The battery connector definitely comes away too easily from the board. If my wife's does it again, I'm thinking I'll see about using a dab of hot glue to see it down. It could damage it but only one way to find out. @angeladarby

Good luck

I just opened and fixed mine. Took less than a minute to fix it. The battery is connected by a red and black wire to a white piece that I needed to press back into the board. Don't be afraid to open it up.

The machine has milk inside it, I put it in the wrong direction and it suction the milk and now it doesn’t work please help

Krys -

What worked for me was to open it up, disconnect the battery, clean up any visible milk (a Q-tip and a little bit of water will work), let it dry, reconnect the battery, and then try charging it.

Steven Bell -

I had a similar problem. I didn’t seal it right and milk got into the actual pump. I took it apart and turned it on and could hear milk inside still. I took the rubber piece off where the two nipples are and cleaned it with a q tip then I took the 3 screws off the actual pump cleaned that out then turned the pump on for a few minutes and it blew out the remaining milk. Works like new again. Hope thats helpful
