My son and girl friend moved into their house about 3 years ago. The existing shower is an Aqualisa Quartz model and the processor box is grey. My understanding is that the grey box was superceded with a black box several years ago, so it will be well outside any warranty.
Recently the pump no longer started when the ‘boost’ button was activated, but the buttons are lit when pressed.
I contacted Aqualisa and the suggestion was there might be an air lock, so I carried out the process to clear a possible air lock, but the pump still does not start when the ‘boost’ button is pressed.
I took the cover off the processor box and observed what was happening with a digital multi meter. There is a circuit board in the middle of the processor box which applies AC volts to the pump when the boost button is pressed, but the pump does not start. As far as I can remember, the level was about 130 V ac at the pump connectors.
I’d like to get the shower working for them as cost effectively as possible, so I’m looking for any help trying to identify the problem. I’ve googled extensively, but can’t find any info on the processor internal circuits, so my questions are:
1) is 130 V ac the correct level to be applied to the pump connectors or has the switching circuit board failed in some manner ?
2) if 130 V ac is the correct level, does that mean the pump has failed ?
3) is there some other mechanism in play that is preventing the pump from starting ?
4) is there any info in the public domain on the processor internal circuitry ?
Thanks for reading and any help
