Default H150i PRO flashing red & high CPU temps [RESOLVED]

Is my new H150i Pro DOA or is there an easy fix?

On initial boot up of my new PC build the led lights on the pump head are flashing red and whilst in the BIOS the CPU (i9-9900K) quickly increases to 90c. The "CPU fan" speed in the BIOS is reading 0.

I've tightened the 4 bolts holding the pump to the CPU, checked all the cables, replaced the SATA power cable and put the USB lead in a different header. The little 3 pin lead is attached to the CPU_FAN header as instructed. However, the same thing happens each time I boot up, except I switch off the PC before it gets to 90c.

Having read these forums, my best guess is that the pump is not working. Does anyone have any other ideas, or do I need to return the H150i Pro for a replacement?
