Aldi Intex spa: how often to change filter? (code E90)

[MikeWLeics]

We've had this spa for just 1 month now, and we have hit the error code E90 several times.
If I remove the filter, the thing will work okay, so it would appear to be that.

I have got a filter cleaning chemical, which did seem to shift the dirt and let the filter be re-used, but technically we are on our 4th filter in 4 weeks!
We always shower before getting in, no frothy suds on us, plus the chemicals (chlorine and pH) look okay (have to tweak them most days).

Is it normal to get this pretty well every week?
We have LOVED having it during this lockdown, but I can't imagine keeping up this regime with the filter - the manual suggested every 6 weeks or so, I think!

Thanks

After you are sure everything is in line & you have a clean filter you could try this

I would imagine this condition could be cause by water imbalances that allow build up on the sensor.

My Intex instruction book says to remove the filters when using the spa, putting them back when done. This may be your issue?

This is one small item in one paragraph, cleverly hidden in the middle of many instructions.
