Airboost won't switch off

I have a 3 year old Mira Sport Max 10.8Kw shower with airboost. I don't use the airboost much, just 30 seconds at the end of a shower. Last time I used it I tried to turn it off with the airboost button, but it won't turn off. Next time I turn the shower on, it comes on, the airboost light flashes several times and airboost stays on. The button will not switch it off. When I switch the shower off, the airboost stops a few seconds before the water does. Any help is appreciated.

You may have a faulty front cover pcb which is causing this.
