For pressure leak - diaphragm and seals replacement, is that a reasonable DIY job? Also do you know if the aforementioned parts would be easy to source?

Blockage - do you mean a blockage in the pump itself?
Got it, is this the type of controller in question? https://forum.lowyat.net/index.php?showtopi...ost&p=107024259

Correct. This is the pump controller.. But over time, I just get the controller board and replace the controller board in the controller casing. Still work like charm. Don’t need to replace the whole head anymore.

The controller is just a few ringgit compared to buying the whole set at 60-100 ringgit. The one u show is a bit expensive at rm240

Got it. I will do some research to see what are my options. May I know where you bought the controller board from?

Gotta try and climb up to confirm model + visual inspection first though sweat.gif

Thanks again for your answer!

Something like this. But better u open the controller (very simple) and just take a photo of the controller.
