Hi all, trying my luck here as my water purifier is leaking when idle. It's a Xiaomi MR432 under the counter model and been owning it without any issues for the past 4 years. The only thing I have done to the machine in the past month is changing the composite and RO filters. I tried resitting the filters but to no avail, the water is still leaking from the RO side.

Does anyone else have experience with this machine and know a shop who services it?

I'm not sure how to troubleshooting here are some pics of the purifier and the RO filter

need to check which part leak. could be simple o-ring

Thank you for the video! I followed it step-by-step and found this part to be leaking.

As you can from the video is dripping on idle. It's rather puzzling because I find:

- all o-rings are in good shape. The exact size and thickness is hard to find even if I want to replace it
- the one part that is broken is this clamp but I don't think it's the issue, also can't find the replacement (not even sure I'm calling it correctly

Is there any specialists that repair or service water purifier?

thats the catch that binds the tube. that is the leaking point?
you can buy generic one
remember to put back the buckle

Lifesaver I'm trying to find it on shopee what is it called exactly?

I forgot to attached the video so here's the leak.

However when I applied pressure to it the water leaks went somewhere else like the bottom of the water filter so could this be a water pressure issue? I tried to close my tap and lil but to no avail.

cant see where the leak come from.
use hairdryer to blow dry the place
then apply water pressure bit by bit to see where it came from.

in theory you can diy the whole set with own components

I have dismantled it once more and I can now see the leakage is on the RO filter side. There's a wheel base at the bottom of the machine where the RO filter sits on. It's even leaking without the filter installed. I have order the replacement part from Taobao and hopefully this is it.

I have finally fixed it! This wheel base thing was really the culprit. From my untrained eyes I don't see anything wrong with it, no cracks whatsoever. The only thing I suspect is the larger washer (not in the pictures) that rest inside the casing which seems flatten.

Less than rm40 to fix and 3 weeks of headache, not bad. Thanks for the link to the video I won't have known how to take it apart!

Well done!
