First of all, when the set temperature is higher than the current
temperature, only the A jets come on to bring warm water in to raise the
temperature. It was the B jets that wouldn't flow when the B jet turnon
button was pressed. The A-jets were fine. B-jets come on only when you get
in and want flow out of B-jets.
I contacted the seller of the hot tub, and they advised there is a B-jet
diverter valve on top of the tub (you can close the valve to prevent B-jets
from coming on), to remove it to let the air out and this should get the
B-jets going again. They called this condition an air lock and said it
occurred when I drained and refilled the tub, and that it could potentially
result in compromised heating. I did this and B-jets work again.
However, the water still is not heating up.
What's strange is I drained and refilled the water several weeks ago, and
the temperature heated right up and was fine until this week.
Now that B-jet flow is fine, I don't know why the water won't heat up.
Steve B implied that the heater element may have overheated and is broken,
but the heat was fine for a couple weeks after I drained and refilled the
tub, and B-jet flow has nothing to do with heating the tub. Again, when
the temperature is below the set point only the A-jets are designed to turn
on.
Unfortunately now I've got the service call in and am waiting until later
this week to get whatever the problem is fixed.
