Problematic RO's

Hi folks…

After much annoyance, calling out techs, and unecssary phone calls, lost dialysis, & blood, a problem seems to have been solved. The RO unit that resides by my machine was deemed faulty. Since it’s been replaced 1 session has been smooth running…

I was beginning to think I’d end up dialysing back in the unit! Aaargh!

Hope everyones doing well:)

Glad you got that sorted out, J. Would you mind sharing which water treatment set up you’re using, and what sort of problems you were having, so other folks who run into it will know what to suspect?

Blah the board ate my last attempt to post…

Here we go… The machine side of the setup is Gamrbo, the WRO (water reverse osmosis)
http://www.gambro.com/int/Treatment-offerings/Self-Care-hemodialysis/Products/Water-Treatment-WRO-300/

The machine itself is a Gamrbo AK95, with several new parts & the latest system software

I must admit the technicians have been very good, tho I’ve had to call them out a fair bit since I started, tho this is the first time the RO has been replaced.

Problems have included a lot of error messages (some can be resolved by phone) where the machine shows a spanner, replacement of the heating/temperature circuit.

Originally filters were changed every 2 months, which has now been cut down to 3. As I understand it, someone from the manufacturers services the machine once a year.

One of the problems has been our extremly high water pressure. Since the waterbird has replaced pipes a lot of people have had plumbing problems, although the machine only needs around 2-3 bar to function.

This was resolved by putting a regulator between the machine & the main supply pipe.

Hope this is of some use.

Hi JW
Great to hear from you. We use the gambro WR300’s in my part of Australia. I liked my older Gambro better as it was much quieter but it stopped dead in the wee small hours a few months ago after 2 and half tears of valiant Nocturnal use. Just heard this tiny little whimper and beep and it died. The new one is working well but LOUD. I shut it in the wardrobe with towels stuffed under the doors otherwise I focus on the noise all night.
Take care

I did a test with a DB meter. The sleeping average DB is 4.5 DB; the WRO from Gambro is 5.8. No one can sleep in this DB volume unless you filter the noise with some sound filtration padding. I just discovered this. Someone suggested me putting ear plugs, but that could be very dangerous not hearing the alarms. So the best thing would be to build a padding covering the WRO to filter the noise, or make a box for it that is sound proof. I do not suggest ear plugs.

I have the very same setup here in Canada, and had some issues with my new RO machine as well. It was a faulty circuit board that continued to read/alarm ‘no water’. We ended up replacing the whole unit after several ‘problem treatments’, and attemps to repair. A very trying time inb our household. It is amazing how reliant we become on our machines at home and how much havoc it causes when they fail to operate properly.

Hi y’all,

Not having an RO machine myself (or a dialysis machine for that matter), I can’t comment on the challenges of insulating it so it’s quieter. It sounds like that might help, but as with any machine, be sure not to block the air vents that allow it to cool.

As far as earplugs, though, if you have normal hearing I doubt that any earplug is so good that you wouldn’t be able to hear alarms through it. Since I travel by air a lot for work, I’ve tried every earplug on the market to cut down on airplane noise. Even the best (those plain rectangular foam ones, believe it or not) don’t even block out conversation, let alone anything shrill. I’d try it while awake and test the alarm to be sure, but strongly suspect that you could both insulate the RO (in some safe way) AND wear earplugs and be okay.
