Spa Milan pump S100201 display lights permanent

[Gifford47]

I've a bestway lazspa Milan 2021 with a pump model S100201. There are 6 wires from pump and 4 wires from display.

I've installed a blue LLC with low pass filter and an esp with latest firmware.
After power on I hear the start beep and after that the display lights permanent. Bubbles, pump and heater are functioning.
I've tried with/without low pass filter and tried several digital pin arrangements but display doesn't work as aspected.

Which setting could be the right for this setup?
@visualapproach do you have an idea?

Oh that's a weird hybrid. I bet you have a 4 wire system but they had a 6 wire cable over...
Treat it like a 4 wire

Ok, but how exactly:/
The pump function only with the following settings (for a 6 pin pump) but not the display

All other settings don't work. Also if i don't use D5 which is originally not connected... that's confusing :/

yes OK, I have the same problem with a Helsinki model - I would be interested in a solution too.

I think here is a reference for the same issue #493

I have now ordered the S100101 pump.

The differences to the s100201 are that the s100101 does not have a WLAN module and no airjet plus. I will then implement the regulation with the rotary control module

Had anyone tried to cut off the preinstalled WiFi module and then install the custom one?

[visualapproach]

It doesn't work with that pump unfortunately

I have the S100201 Airjet model with WiFi modul. Problem is, that the oriinal WiFi is now broken.. Is it possible to add the board to it? Thank you!

Not unless you replace the motherboard with a non-wifi model I'm afraid
