blue light stuck on start stop button, water flow on but now being pumped

Hi. I replaced the mark one unit with tan IPx4 version about 5 years ago. I did not replace the control. However now the blue light is stuck on (but not fully bright blue) and the water flow remains on but it's not being pumped. The only way to turn it off is unplug the unit in the loft and turn the water off on the hot and cold feed. Do you think it's the control unit that needs changing as it's probably 10 years old.

It may be the controller or the pcb in the processor that is faulty.

You will need to contact Aqualisa direct about this.
