Andyw77 Posted May 31, 2023 Report Share Posted May 31, 2023 Jets and lights work fine, the power and ready light is blinking and heater not working. No heater light on at all. Circ pump is working but I don’t feel like it’s pushing lots of water. I can tell the water is moving but not bubbling. Also that clear tube in the picture does not have water in it and I have no idea where it goes. I’ve pulled the check valve off and it’s sucking but no water is in it. Help please!

cranbiz Posted May 31, 2023 Report Share Posted May 31, 2023 As for the heater, when the tub is calling for heat, measure the voltage on the heater terminals. Depending on your setup, you should have either 120V or 240V across the terminals when the tub wants heat. If you do have voltage, it's a bad heater. If you don't, it's most likely a bad relay. Looking at the board, do you have any burn marks on it? Upload pictures of your control board and wiring diagram. Quote Link to comment Share on other sites More sharing options...

cranbiz Posted May 31, 2023 Report Share Posted May 31, 2023 OK, 110V tub wiring. Heater light never comes on? Is the display OK? Any codes, messages or dashes on it if it's ok? Quote Link to comment Share on other sites More sharing options...
Andyw77 Posted May 31, 2023 Author Report Share Posted May 31, 2023 No codes, when I first power it on it sits there for a minute and then the power and ready light flashes. The jets, light and circ pump all work no problem just not the heater. There is also a buzzing sound coming from the control board Quote Link to comment Share on other sites More sharing options...
tjr Posted June 1, 2023 Report Share Posted June 1, 2023 Power and ready lights flashing together is indicator of circ pump flow issue. The pressure switch built into heater is not closing. Could be dirty filter, weak circ pump or bad pressure switch.Also verify the check valve opens and closes with jet pump operation. Remove filter from hot tub and see if the heater light on circuit board comes on. The pump looks like the original and even though it is moving water its flow is reduced and won't close pressure switch. Test the switch by removing connector from board with multimeter set to continuity. 1 Quote Link to comment Share on other sites More sharing options...
Andyw77 Posted June 21, 2023 Author Report Share Posted June 21, 2023 I noticed when I first plug up my tub that the circ pump is pushing pretty hard and then when the power and ready light starts blinking it doesn’t push as hard anymore… what could that be Quote Link to comment Share on other sites More sharing options...
tjr Posted June 21, 2023 Report Share Posted June 21, 2023 Are you talking jet pump or circulation pump? Quote Link to comment Share on other sites More sharing options...
Andyw77 Posted June 21, 2023 Author Report Share Posted June 21, 2023 Which ever one pushes water from the bottom of the tub Quote Link to comment Share on other sites More sharing options...
tjr Posted June 21, 2023 Report Share Posted June 21, 2023 That is the circulation pump. when it stops moving water what voltage do you get on the board at white and black circ pump connections. Middle set of wires going into bottom of IQ box. On right hand section of circuit board. Quote Link to comment Share on other sites More sharing options...
