I finally got my hot tub fixed after about a year of sitting empty, it is a caldera Hawaiian model. Last winter I winterized it after I had a problem with It tripping the breaker every day. I finally installed a heater and one new circulation pump. Cleaned and sterilized it and finally filled it and balanced the water. We used it last night and I realized water is not coming out of half the jets even though both pumps are running. I'm not even sure what could be the problem. I tried changing position of the diverter valves but it didn't move any flow to those jets.
