Aqualisa Quartz diverter issue

Hello,

My Aqualisa Quartz (gravity pumped) system, installed in 2018, has recently started to develop problems.

For the first shower in the morning, I have to fiddle with the two buttons before any water comes out of an outlet (sometimes the one selected, sometimes not). The blue light flashes correctly and then remains steady once the temperature is reached, which makes me think the diverter might be the issue. I have already removed and cleaned the top shower head, but this made no difference.

It’s worth noting that we have a second Aqualisa in the ensuite which works perfectly.

Is it possible to open and repair the diverter, or should it be replaced entirely?
