My customer's Stuart Turner Monsoon 1.5N shower pump was turned off while I changed the shower valve and when turned back on no longer worked. ST confirmed this is a know fault that just by turning the electricity supply off and on again can "fry the PCB". they gave me the part number for a new PCB then told me it was no longer available and that I would need a "service pack" which contains a lot of parts not needed for the job. It would also cost almost as much as a new pump. Does anybody know where I can get a PCB for a ST Monsoon 1.5N please. Thankyou.
