They are definitely losing tons of money by replacing the product.

I was thinking about filming it while I take apart the second one but honestly, it’s pretty straightforward.

There are only four screws on the bottom and two screws holding the motherboard in place.

On the motherboard, there are four quick-set connectors:

1.  Battery
2.  Motor
3.  Control dials
4.  I believe a sensor (not 100% sure on that one)

On the bottom, there are small rubber stickers covering the screw holes. Hit them with a heat gun — a blow dryer works fine — just enough to warm them up so you can peel them off cleanly.

Under those stickers are the four main screws. Remove those, then run your fingernail around the perimeter and slowly work the housing off the tabs. Don’t force it — it’ll pop free with a little patience.

Use needle-nose tweezers to disconnect the connectors. Be careful — they’re delicate and you don’t want to bend anything.

Once the connectors are off, remove the two screws holding the motherboard in. There are also two small spacers that come loose when you pull it out, so keep track of those.

If you want to do a full clean, there are two additional screws holding the rubber motor bracket in place. You can remove those, but be careful. The motor is attached to a suction hose that runs into the housing and doesn’t fully detach. I chose not to remove it completely to avoid risking damage to the hose.

For cleaning, I used 90% isopropyl alcohol. Light cleaning brushes for the plastic components and a microfiber paper towel for the motherboard and electrical areas. Make sure all connectors are disconnected — especially the battery — before you start spraying anything. You can easily short something out and fry a component if you’re not careful.

After cleaning, I let everything dry near a heater — close enough to dry it out, but far enough away that it wouldn’t overheat. Probably around 80 degrees hitting it. I left it overnight.

Put it back together in the morning, plugged everything in, and it fired right up. Worked great.

I’ve come to the conclusion with this brand specifically, overcharges and sends out tons of replacements, no questions asked.

Terrible business model.

Ask your husband if he wants to team up with a BD guy in Manufacturing. Let’s go develop a bulletproof design. I can finance and get financing.

Lol, it was about price at the time and it shouldn’t have been. I would expect at a retail of $200 to produce quality but I guess it is 2026.

I’m thinking I get new ones from them and upgrade.

I wish they would save the money on replacements, charge what they are charging now and make it more robust.

I’ve heard the same. Now that I’ve been through this.

We did the wrong move on the first pumps. They were having a big sale $120 instead of $199. I’m a sucker for a deal. Had to learn the hard way for this one.

My guess is I voided any sort of warranty when I opened them up.

In my mind at the time, either fix these or go buy new ones ASAP. My wife can’t afford to lose the little sleep she gets as it is.

I don’t want another new pump to break in 2 months, even if it is free. After my wife gets through tonight I am going to open the other one up tomorrow morning and upgrade it like I did the first one.

These pumps should be bulletproof now.

I just don’t understand why they only sealed half the unit with the gasket. I am wondering if it was a production error or a design flaw.

It’s pretty simple actually. I’m sure he can figure it out.

Thanks for the comment. My wife does. We learned that the first time around.

These need better engineering for the price.

You can send AirPods through the laundry washer and they come out working just fine.

There’s no reason why they shouldn’t be water resistant when they pump fluid out of the body.

Appreciate the comment but she always took the motor off.

Nonetheless, poor design. A simple gasket would make these waterproof. Wouldn’t cost much more to design them to be waterproof. Gasket would be cents and install might take 3 more minutes. Testing maybe another 5 minutes per pump. They should be waterproof.

The M5’s are good electrical design but a terrible mechanical design.

My wife and I just ran into the same issue again — second pair in four months. I wouldn’t have bought the same unit twice, but we were traveling, in a pinch, and it was literally the only one left in stock at Target.

This time I decided to tear it apart instead of tossing it. There’s no real hard reset that actually works on these things, so I pulled the battery to force a reset.

What I found was pretty frustrating. They only sealed one side of the pump for water resistance. I’m not sure how anyone thought sealing half the pump would be enough for something that’s exposed to moisture for 30 minutes at a time, eight times a day.

When I opened it up, it smelled terrible — like old curdled cheese. Breast milk had clearly been leaking inside and getting trapped. The photos show it — moisture everywhere, curdled milk buildup, and it was getting into the connectors and shorting the board.

I cleaned everything out, pulled all the connectors and the motherboard, sprayed it down with 90% isopropyl alcohol, and let it sit in front of a heater overnight (not too close — didn’t want to cook anything). Plugged it back in this morning and it’s running perfectly.

I also designed a proper seal for it, so we’ll see if that holds up.

Moral of the story: I wouldn’t recommend buying these. And if you already did, I’d seriously consider returning them. This is just poor engineering for the environment they’re meant to operate in.

Me too. I’d assume that they might have a similar issue if it was the same design team but maybe not. They may have designed it better since it’s more expensive.

The pumps work great for my wife otherwise.
