On 712 the pumps for the Aquahot all get there power from the electronic board for the aquahot the preheat does not need engine merge to work the preheat is the bottom pump if you still have the pumps with the clear cover just because the pump is turning does not mean it is working they are magnetic drive, the plastic on my impeller drive all cracked and seized I peeled it off coated it with JB weld made an arbor for it ground it down to the right size, did not work for long waste of time
